XTERM(1)			X Window System			      XTERM(1)

NAME
       xterm - terminal	emulator for X

SYNOPSIS
       xterm [-toolkitoption ...] [-option ...]	[shell]

DESCRIPTION
       The xterm program is a terminal emulator	for the	X Window System.  It
       provides	DEC VT102/VT220	and selected features from higher-level
       terminals such as VT320/VT420/VT520 (VTxxx).  It	also provides
       Tektronix 4014 emulation	for programs that cannot use the window	system
       directly.  If the underlying operating system supports terminal
       resizing	capabilities (for example, the SIGWINCH	signal in systems
       derived from 4.3BSD), xterm will	use the	facilities to notify programs
       running in the window whenever it is resized.

       The VTxxx and Tektronix 4014 terminals each have	their own window so
       that you	can edit text in one and look at graphics in the other at the
       same time.  To maintain the correct aspect ratio	(height/width),
       Tektronix graphics will be restricted to	the largest box	with a 4014's
       aspect ratio that will fit in the window.  This box is located in the
       upper left area of the window.

       Although	both windows may be displayed at the same time,	one of them is
       considered the "active" window for receiving keyboard input and
       terminal	output.	 This is the window that contains the text cursor.
       The active window can be	chosen through escape sequences, the VT
       Options menu in the VTxxx window, and the Tek Options menu in the 4014
       window.

EMULATIONS
       Xterm provides usable emulations	of related DEC terminals:

       o   VT52	emulation is complete.

       o   VT102 emulation is fairly complete, but does	not support autorepeat
	   (because that would affect the keyboard used	by other X clients).

	   Double-size characters are displayed	properly if your font server
	   supports scalable bitmap fonts.

       o   VT220 emulation does	not support soft fonts,	it is otherwise
	   complete.

       o   VT420 emulation (the	default) supports controls for manipulating
	   rectangles of characters as well as left/right margins.

	   Xterm does not support some other features which are	not suitable
	   for emulation, e.g.,	two-sessions.

       Terminal	database (terminfo (5) or termcap (5)) entries that work with
       xterm include

	      an optional platform-specific entry ("xterm"),
	      "xterm",
	      "vt102",
	      "vt100",
	      "ansi" and
	      "dumb"

       Xterm automatically searches the	terminal database in this order	for
       these entries and then sets the "TERM" variable (and the	"TERMCAP"
       environment variable on a few older systems).  The alternatives after
       "xterm" are very	old, from the late 1980s.

       VT100 and VT102 emulations are commonly equated,	though they actually
       differ.	The VT102 provided controls for	inserting and deleting lines.

       Similarly, "ansi" and "vt100" are often equated.	 These are not really
       the same.  For instance,	they use different controls for	scrolling (but
       xterm supports both).  These features differ in an "ansi" terminal
       description from	xterm:

       acsc
	       Pseudo-graphics (line-drawing) uses a different mapping.

       xenl
	       Xterm wraps text	at the right margin using the VT100 "newline
	       glitch" behavior.

       Because of the wrapping behavior, you would occasionally	have to
       repaint the screen when using a text editor with	the "ansi"
       description.

       You may also use	descriptions corresponding to the various supported
       emulations such as "vt220" or  "vt420", but should set the terminal
       emulation level with the	decTerminalID resource.

       On most systems,	xterm will use the terminfo database.  Some older
       systems use termcap.  (The "TERMCAP" environment	variable is not	set if
       xterm is	linked against a terminfo library, since the requisite
       information is not provided by the termcap emulation of terminfo
       libraries).

       Many of the special xterm features may be modified under	program
       control through a set of	escape sequences different from	the standard
       VTxxx escape sequences (see Xterm Control Sequences).

       The Tektronix 4014 emulation is also fairly good.  It supports 12-bit
       graphics	addressing, scaled to the window size.	Four different font
       sizes and five different	lines types are	supported.  There is no	write-
       through or defocused mode support.  The Tektronix text and graphics
       commands	are recorded internally	by xterm and may be written to a file
       by sending the COPY escape sequence (or through the Tektronix menu; see
       below).	The name of the	file will be

	   "COPYyyyy-MM-dd.hh:mm:ss"

       where yyyy, MM, dd, hh, mm and ss are the year, month, day, hour,
       minute and second when the COPY was performed (the file is created in
       the directory xterm is started in, or the home directory	for a login
       xterm).

       Not all of the features described in this manual	are necessarily
       available in this version of xterm.  Some (e.g.,	the non-VT220
       extensions) are available only if they were compiled in,	though the
       most commonly-used are in the default configuration.

OTHER FEATURES
       Xterm automatically highlights the text cursor when the pointer enters
       the window (selected) and unhighlights it when the pointer leaves the
       window (unselected).  If	the window is the focus	window,	then the text
       cursor is highlighted no	matter where the pointer is.

       In VTxxx	mode, there are	escape sequences to activate and deactivate an
       alternate screen	buffer,	which is the same size as the display area of
       the window.  When activated, the	current	screen is saved	and replaced
       with the	alternate screen.  Saving of lines scrolled off	the top	of the
       window is disabled until	the normal screen is restored.	The usual
       terminal	description for	xterm allows the visual	editor vi(1) to	switch
       to the alternate	screen for editing and to restore the screen on	exit.
       A popup menu entry makes	it simple to switch between the	normal and
       alternate screens for cut and paste.

       In either VTxxx or Tektronix mode, there	are escape sequences to	change
       the name	of the windows.	 Additionally, in VTxxx	mode, xterm implements
       the window-manipulation control sequences from dtterm, such as resizing
       the window, setting its location	on the screen.

       Xterm allows character-based applications to receive mouse events
       (currently button-press and release events, and button-motion events)
       as keyboard control sequences.  See Xterm Control Sequences for
       details.

OPTIONS
       Because xterm uses the X	Toolkit	library, it accepts the	standard X
       Toolkit command line options.  Xterm also accepts many application-
       specific	options.

       By convention, if an option begins with a "+" instead of	a "-", the
       option is restored to its default value.

       Most of the xterm options are actually parsed by	the X Toolkit, which
       sets resource values, and overrides corresponding resource-settings in
       your X resource files.  Xterm provides the X Toolkit with a table of
       options.	 A few of these	are marked, telling the	X Toolkit to ignore
       them (-help, -version, -class, -e, and -into).  After the X Toolkit has
       parsed the command-line parameters, it removes those which it handles,
       leaving the specially-marked parameters for xterm to handle.

       These options do	not set	a resource value, and are handled specially:

       -version
	       This causes xterm to print a version number to the standard
	       output, and then	exit.

       -help   This causes xterm to print out a	verbose	message	describing its
	       options,	one per	line.  The message is written to the standard
	       output.	After printing the message, xterm exits.  Xterm
	       generates this message, sorting it and noting whether a
	       "-option" or a "+option"	turns the feature on or	off, since
	       some features historically have been one	or the other.  Xterm
	       generates a concise help	message	(multiple options per line)
	       when an unknown option is used, e.g.,

		   xterm -z

	       If the logic for	a particular option such as logging is not
	       compiled	into xterm, the	help text for that option also is not
	       displayed by the	-help option.

       The -version and	-help options are interpreted even if xterm cannot
       open the	display, and are useful	for testing and	configuration scripts.
       Along with -class, they are checked before other	options.  To do	this,
       xterm has its own (much simpler)	argument parser, along with a table of
       the X Toolkit's built-in	list of	options.

       Relying upon the	X Toolkit to parse the options and associated values
       has the advantages of simplicity	and good integration with the X
       resource	mechanism.  There are a	few drawbacks

       o   Xterm cannot	tell easily whether a resource value was set by	one of
	   the external	resource- or application-defaults files, whether it
	   was set using xrdb(1), or if	it was set through the -xrm option or
	   via some directly relevant command-line option.  Xterm sees only
	   the end-result: a value supplied when creating its widgets.

       o   Xterm does not know the order in which particular options and items
	   in resource files are evaluated.  Rather, it	sees all of the	values
	   for a given widget at the same time.	 In the	design of these
	   options, some are deemed more important, and	can override other
	   options.

	   The X Toolkit uses patterns (constants and wildcards) to match
	   resources.  Once a particular pattern has been used,	it will	not
	   modify it.  To override a given setting, a more-specific pattern
	   must	be used, e.g., replacing "*" with ".".	Some poorly-designed
	   resource files are too specific to allow the	command-line options
	   to affect the relevant widget values.

       o   In a	few cases, the X Toolkit combines its standard options in ways
	   which do not	work well with xterm.  This happens with the color
	   (-fg, -bg) and reverse (-rv)	options.  Xterm	makes a	special	case
	   of these and	adjusts	its sense of "reverse" to lessen user
	   surprise.

       One parameter (after all	options) may be	given.	That overrides xterm's
       built-in	choice of shell	program:

       o   If the parameter is not a relative path, i.e., beginning with "./"
	   or "../", xterm looks for the file in the user's PATH.  In either
	   case, this check fails if xterm cannot construct an absolute	path.

       o   If that check fails (or if no such parameter	is given), xterm next
	   checks the "SHELL" variable.	 If that specifies an executable file,
	   xterm will attempt to start that.  However, xterm additionally
	   checks if it	is a valid shell, and will unset "SHELL" if it is not.

       o   If "SHELL" is not set to an executable file,	xterm tries to use the
	   shell program specified in the user's password file entry.  As
	   before, xterm verifies if this is a valid shell.

       o   Finally, if the password file entry does not	specify	a valid	shell,
	   xterm uses /bin/sh.

       The -e option cannot be used with this parameter	since it uses all
       parameters following the	option.

       Xterm validates shell programs by finding their pathname	in the text
       file /etc/shells.  It treats the	environment variable "SHELL" specially
       because (like "TERM"), xterm both reads and updates the variable, and
       because the program started by xterm is not necessarily a shell.

       The other options are used to control the appearance and	behavior.  Not
       all options are necessarily configured into your	copy of	xterm:

       -132    Normally, the VT102 DECCOLM escape sequence that	switches
	       between 80 and 132 column mode is ignored.  This	option causes
	       the DECCOLM escape sequence to be recognized, and the xterm
	       window will resize appropriately.

       -ah     This option indicates that xterm	should always highlight	the
	       text cursor.  By	default, xterm will display a hollow text
	       cursor whenever the focus is lost or the	pointer	leaves the
	       window.

       +ah     This option indicates that xterm	should do text cursor
	       highlighting based on focus.

       -ai     This option disables active icon	support	if that	feature	was
	       compiled	into xterm.  This is equivalent	to setting the vt100
	       resource	activeIcon to "false".

       +ai     This option enables active icon support if that feature was
	       compiled	into xterm.  This is equivalent	to setting the vt100
	       resource	activeIcon to "true".

       -aw     This option indicates that auto-wraparound should be allowed,
	       and is equivalent to setting the	vt100 resource autoWrap	to
	       "true".

	       Auto-wraparound allows the cursor to automatically wrap to the
	       beginning of the	next line when it is at	the rightmost position
	       of a line and text is output.

       +aw     This option indicates that auto-wraparound should not be
	       allowed,	and is equivalent to setting the vt100 resource
	       autoWrap	to "false".

       -b number
	       This option specifies the size of the inner border (the
	       distance	between	the outer edge of the characters and the
	       window border) in pixels.  That is the vt100 internalBorder
	       resource.  The default is "2".

       -baudrate number
	       Set the line-speed, used	to test	the behavior of	applications
	       that use	the line-speed when optimizing their output to the
	       screen.	The default is "38400".

       +bc     turn off	text cursor blinking.  This overrides the cursorBlink
	       resource.

       -bc     turn on text cursor blinking.  This overrides the cursorBlink
	       resource.

       -bcf milliseconds
	       set the amount of time text cursor is off when blinking via the
	       cursorOffTime resource.

       -bcn milliseconds
	       set the amount of time text cursor is on	when blinking via the
	       cursorOnTime resource.

       -bdc    Set the vt100 resource colorBDMode to "false", disabling	the
	       display of characters with bold attribute as color.

       +bdc    Set the vt100 resource colorBDMode to "true", enabling the
	       display of characters with bold attribute as color rather than
	       bold.

       -cb     Set the vt100 resource cutToBeginningOfLine to "false".

       +cb     Set the vt100 resource cutToBeginningOfLine to "true".

       -cc characterclassrange:value[, ...]
	       This sets classes indicated by the given	ranges for using in
	       selecting by words (see CHARACTER CLASSES and the charClass
	       resource).

       -cjk_width
	       Set the cjkWidth	resource to "true".  When turned on,
	       characters with East Asian Ambiguous (A)	category in UTR	11
	       have a column width of 2.  Otherwise, they have a column	width
	       of 1.  This may be useful for some legacy CJK text terminal-
	       based programs assuming box drawings and	others to have a
	       column width of 2.  It also should be turned on when you
	       specify a TrueType CJK double-width (bi-width/monospace)	font
	       either with -fa at the command line or faceName resource.  The
	       default is "false"

       +cjk_width
	       Reset the cjkWidth resource.

       -class string
	       This option allows you to override xterm's resource class.
	       Normally	it is "XTerm", but can be set to another class such as
	       "UXTerm"	to override selected resources.

	       X Toolkit sets the WM_CLASS property using the instance name
	       and this	class value.

       -cm     This option disables recognition	of ANSI	color-change escape
	       sequences.  It sets the colorMode resource to "false".

       +cm     This option enables recognition of ANSI color-change escape
	       sequences.  This	is the same as the vt100 resource colorMode.

       -cn     This option indicates that newlines should not be cut in	line-
	       mode selections.	 It sets the cutNewline	resource to "false".

       +cn     This option indicates that newlines should be cut in line-mode
	       selections.  It sets the	cutNewline resource to "true".

       -cr color
	       This option specifies the color to use for text cursor.	The
	       default is to use the same foreground color that	is used	for
	       text.  It sets the cursorColor resource according to the
	       parameter.

       -cu     This option indicates that xterm	should work around a bug in
	       the more(1) program that	causes it to incorrectly display lines
	       that are	exactly	the width of the window	and are	followed by a
	       line beginning with a tab (the leading tabs are not displayed).
	       This option is so named because it was originally thought to be
	       a bug in	the curses(3x) cursor motion package.

       +cu     This option indicates that xterm	should not work	around the
	       more(1) bug mentioned above.

       -dc     This option disables the	escape sequence	to change dynamic
	       colors: the vt100 foreground and	background colors, its text
	       cursor color, the pointer cursor	foreground and background
	       colors, the Tektronix emulator foreground and background
	       colors, its text	cursor color and highlight color.  The option
	       sets the	dynamicColors option to	"false".

       +dc     This option enables the escape sequence to change dynamic
	       colors.	The option sets	the dynamicColors option to "true".

       -e program [ arguments ... ]
	       This option specifies the program (and its command line
	       arguments) to be	run in the xterm window.  It also sets the
	       window title and	icon name to be	the basename of	the program
	       being executed if neither -T nor	-n are given on	the command
	       line.

	       NOTE: This must be the last option on the command line.

       -en encoding
	       This option determines the encoding on which xterm runs.	 It
	       sets the	locale resource.  Encodings other than UTF-8 are
	       supported by using luit.	 The -lc option	should be used instead
	       of -en for systems with locale support.

       -fb font
	       This option specifies a font to be used when displaying bold
	       text.  It sets the boldFont resource.

	       This font must be the same height and width as the normal font,
	       otherwise it is ignored.	 If only one of	the normal or bold
	       fonts is	specified, it will be used as the normal font and the
	       bold font will be produced by overstriking this font.

	       See also	the discussion of boldMode and alwaysBoldMode
	       resources.

       -fa pattern
	       This option sets	the pattern for	fonts selected from the
	       FreeType	library	if support for that library was	compiled into
	       xterm.  This corresponds	to the faceName	resource.  When	a CJK
	       double-width font is specified, you also	need to	turn on	the
	       cjkWidth	resource.

	       If you specify both -fa and the X Toolkit option	-fn, the -fa
	       setting overrides the latter.

	       See also	the renderFont resource, which combines	with this to
	       determine whether FreeType fonts	are initially active.

       -fbb    This option indicates that xterm	should compare normal and bold
	       fonts bounding boxes to ensure they are compatible.  It sets
	       the freeBoldBox resource	to "false".

       +fbb    This option indicates that xterm	should not compare normal and
	       bold fonts bounding boxes to ensure they	are compatible.	 It
	       sets the	freeBoldBox resource to	"true".

       -fbx    This option indicates that xterm	should not assume that the
	       normal and bold fonts have VT100	line-drawing characters.  If
	       any are missing,	xterm will draw	the characters directly.  It
	       sets the	forceBoxChars resource to "false".

       +fbx    This option indicates that xterm	should assume that the normal
	       and bold	fonts have VT100 line-drawing characters.  It sets the
	       forceBoxChars resource to "true".

       -fd pattern
	       This option sets	the pattern for	double-width fonts selected
	       from the	FreeType library if support for	that library was
	       compiled	into xterm.  This corresponds to the
	       faceNameDoublesize resource.

       -fi font
	       This option sets	the font for active icons if that feature was
	       compiled	into xterm.

	       See also	the discussion of the iconFont resource.

       -fs size
	       This option sets	the pointsize for fonts	selected from the
	       FreeType	library	if support for that library was	compiled into
	       xterm.  This corresponds	to the faceSize	resource.

       -fullscreen
	       This option indicates that xterm	should ask the window manager
	       to let it use the full-screen for display, e.g.,	without	window
	       decorations.  It	sets the fullscreen resource to	"true".

       +fullscreen
	       This option indicates that xterm	should not ask the window
	       manager to let it use the full-screen for display.  It sets the
	       fullscreen resource to "false".

       -fw font
	       This option specifies the font to be used for displaying	wide
	       text.  By default, it will attempt to use a font	twice as wide
	       as the font that	will be	used to	draw normal text.  If no
	       double-width font is found, it will improvise, by stretching
	       the normal font.	 This corresponds to the wideFont resource.

       -fwb font
	       This option specifies the font to be used for displaying	bold
	       wide text.  By default, it will attempt to use a	font twice as
	       wide as the font	that will be used to draw bold text.  If no
	       double-width font is found, it will improvise, by stretching
	       the bold	font.  This corresponds	to the wideBoldFont resource.

       -fx font
	       This option specifies the font to be used for displaying	the
	       preedit string in the "OverTheSpot" input method.

	       See also	the discussion of the ximFont resource.

       -hc color
	       (see -selbg).

       -hf     This option indicates that HP function key escape codes should
	       be generated for	function keys.	It sets	the hpFunctionKeys
	       resource	to "true".

       +hf     This option indicates that HP function key escape codes should
	       not be generated	for function keys.  It sets the	hpFunctionKeys
	       resource	to "false".

       -hm     Tells xterm to use highlightTextColor and highlightColor	to
	       override	the reversed foreground/background colors in a
	       selection.  It sets the highlightColorMode resource to "true".

       +hm     Tells xterm not to use highlightTextColor and highlightColor to
	       override	the reversed foreground/background colors in a
	       selection.  It sets the highlightColorMode resource to "false".

       -hold   Turn on the hold	resource, i.e.,	xterm will not immediately
	       destroy its window when the shell command completes.  It	will
	       wait until you use the window manager to	destroy/kill the
	       window, or if you use the menu entries that send	a signal,
	       e.g., HUP or KILL.

       +hold   Turn off	the hold resource, i.e., xterm will immediately
	       destroy its window when the shell command completes.

       -ie     Turn on the ptyInitialErase resource, i.e., use the pseudo-
	       terminal's sense	of the stty erase value.

       +ie     Turn off	the ptyInitialErase resource, i.e., set	the stty erase
	       value using the kb string from the termcap entry	as a
	       reference, if available.

       -im     Turn on the useInsertMode resource, which forces	use of insert
	       mode by adding appropriate entries to the TERMCAP environment
	       variable.  (This	option is ignored on most systems, because
	       TERMCAP is not used).

       +im     Turn off	the useInsertMode resource.

       -into windowId
	       Given an	X window identifier (an	integer, which can be
	       hexadecimal, octal or decimal according to whether it begins
	       with "0x", "0" or neither), xterm will reparent its top-level
	       shell widget to that window.  This is used to embed xterm
	       within other applications.

	       For instance, there are scripts for Tcl/Tk and Gtk which	can be
	       used to demonstrate the feature.	 When using Gtk, there is a
	       limitation of that toolkit which	requires that xterm's
	       allowSendEvents resource	is enabled.

       -itc    Set the vt100 resource colorITMode to "false", disabling	the
	       display of characters with italic attribute as color.

       +itc    Set the vt100 resource colorITMode to "true", enabling the
	       display of characters with italic attribute as color rather
	       than italic.

       -j      This option indicates that xterm	should do jump scrolling.  It
	       corresponds to the jumpScroll resource.	Normally, text is
	       scrolled	one line at a time; this option	allows xterm to	move
	       multiple	lines at a time	so that	it does	not fall as far
	       behind.	Its use	is strongly recommended	since it makes xterm
	       much faster when	scanning through large amounts of text.	 The
	       VT100 escape sequences for enabling and disabling smooth	scroll
	       as well as the VT Options menu can be used to turn this feature
	       on or off.

       +j      This option indicates that xterm	should not do jump scrolling.

       -k8     This option sets	the allowC1Printable resource.	When
	       allowC1Printable	is set,	xterm overrides	the mapping of C1
	       control characters (code	128-159) to treat them as printable.

       +k8     This option resets the allowC1Printable resource.

       -kt keyboardtype
	       This option sets	the keyboardType resource.  Possible values
	       include:	"unknown", "default", "legacy",	"hp", "sco", "sun",
	       "tcap" and "vt220".

	       The value "unknown", causes the corresponding resource to be
	       ignored.

	       The value "default", suppresses the associated resources

	       hpFunctionKeys,
	       scoFunctionKeys,
	       sunFunctionKeys,
	       tcapFunctionKeys,
	       oldXtermFKeys and
	       sunKeyboard,

	       using the Sun/PC	keyboard layout.

       -l      Turn logging on,	unless disabled	by the logInhibit resource.

	       Some versions of	xterm may have logging enabled.	 However,
	       normally	logging	is not supported, due to security concerns in
	       the early 1990s.	 That was a problem in X11R4 xterm (1989)
	       which was addressed by a	patch to X11R5 late in 1993.  X11R6
	       included	these fixes.  The older	version	(when running with
	       root privilege) would create the	log file using root privilege.
	       The reason why xterm ran	with root privileges was to open
	       pseudo-terminals.  Those	privileges are now needed only on very
	       old systems: Unix98 pseudo-terminals made the BSD scheme
	       unnecessary.

	       Unless overridden by the	-lf option or the logFile resource:

	       o   If the filename is "-", then	logging	is sent	to the
		   standard output.

	       o   Otherwise a filename	is generated, and the log file is
		   written to the directory from which xterm is	invoked.

	       o   The generated filename is of	the form

		       XtermLog.XXXXXX

		   or

		       Xterm.log.hostname.yyyy.mm.dd.hh.mm.ss.XXXXXX

		   depending on	how xterm was built.

       +l      Turn logging off.

       -lc     Turn on support of various encodings according to the users'
	       locale setting, i.e., LC_ALL, LC_CTYPE, or LANG environment
	       variables.  This	is achieved by turning on UTF-8	mode and by
	       invoking	luit for conversion between locale encodings and
	       UTF-8.  (luit is	not invoked in UTF-8 locales.)	This
	       corresponds to the locale resource.

	       The actual list of encodings which are supported	is determined
	       by luit.	 Consult the luit manual page for further details.

	       See also	the discussion of the -u8 option which supports	UTF-8
	       locales.

       +lc     Turn off	support	of automatic selection of locale encodings.
	       Conventional 8bit mode or, in UTF-8 locales or with -u8 option,
	       UTF-8 mode will be used.

       -lcc path
	       File name for the encoding converter from/to locale encodings
	       and UTF-8 which is used with -lc	option or locale resource.
	       This corresponds	to the localeFilter resource.

       -leftbar
	       Force scrollbar to the left side	of VT100 screen.  This is the
	       default,	unless you have	set the	rightScrollBar resource.

       -lf filename
	       Specify the log filename.  This sets the	logFile	resource.  If
	       set to "-", xterm writes	its log	to the standard	output.	 See
	       the -l option.

       -ls     This option indicates that the shell that is started in the
	       xterm window will be a login shell (i.e., the first character
	       of argv[0] will be a dash, indicating to	the shell that it
	       should read the user's .login or	.profile).

	       The -ls flag and	the loginShell resource	are ignored if -e is
	       also given, because xterm does not know how to make the shell
	       start the given command after whatever it does when it is a
	       login shell - the user's	shell of choice	need not be a Bourne
	       shell after all.	 Also, xterm -e	is supposed to provide a
	       consistent functionality	for other applications that need to
	       start text-mode programs	in a window, and if loginShell were
	       not ignored, the	result of ~/.profile might interfere with
	       that.

	       If you do want the effect of -ls	and -e simultaneously, you may
	       get away	with something like

		   xterm -e /bin/bash -l -c "my	command	here"

	       Finally,	-ls is not completely ignored, because xterm -ls -e
	       does write a /etc/wtmp entry (if	configured to do so), whereas
	       xterm -e	does not.

       -maximized
	       This option indicates that xterm	should ask the window manager
	       to maximize its layout on startup.  This	corresponds to the
	       maximized resource.

	       Maximizing is not the reverse of	iconifying; it is possible to
	       do both with certain window managers.

       +maximized
	       This option indicates that xterm	should ask the window manager
	       to not maximize its layout on startup.

       +ls     This option indicates that the shell that is started should not
	       be a login shell	(i.e., it will be a normal "subshell").

       -mb     This option indicates that xterm	should ring a margin bell when
	       the user	types near the right end of a line.

       +mb     This option indicates that margin bell should not be rung.

       -mc milliseconds
	       This option specifies the maximum time between multi-click
	       selections.

       -mesg   Turn off	the messages resource, i.e., disallow write access to
	       the terminal.

       +mesg   Turn on the messages resource, i.e., allow write	access to the
	       terminal.

       -mk_width
	       Set the mkWidth resource	to "true".  This makes xterm use a
	       built-in	version	of the wide-character width calculation.  The
	       default is "false"

       +mk_width
	       Reset the mkWidth resource.

       -ms color
	       This option specifies the color to be used for the pointer
	       cursor.	The default is to use the foreground color.  This sets
	       the pointerColor	resource.

       -nb number
	       This option specifies the number	of characters from the right
	       end of a	line at	which the margin bell, if enabled, will	ring.
	       The default is "10".

       -nul    This option disables the	display	of underlining.

       +nul    This option enables the display of underlining.

       -pc     This option enables the PC-style	use of bold colors (see
	       boldColors resource).

       +pc     This option disables the	PC-style use of	bold colors.

       -pob    This option indicates that the window should be raised whenever
	       a Control-G is received.

       +pob    This option indicates that the window should not	be raised
	       whenever	a Control-G is received.

       -report-charclass
	       Print a report to the standard output showing information about
	       the character-classes which can be altered using	the charClass
	       resource.

       -report-colors
	       Print a report to the standard output showing information about
	       colors as xterm allocates them.	This corresponds to the
	       reportColors resource.

       -report-fonts
	       Print a report to the standard output showing information about
	       fonts which are loaded.	This corresponds to the	reportFonts
	       resource.

       -report-icons
	       Print a report to the standard output showing information about
	       pixmap-icons which are loaded.  This corresponds	to the
	       reportIcons resource.

       -report-xres
	       Print a report to the standard output showing the values	of
	       boolean,	numeric	or string X resources for the VT100 widget
	       when initialization is complete.	 This corresponds to the
	       reportXRes resource.

       -rightbar
	       Force scrollbar to the right side of VT100 screen.

       -rvc    This option disables the	display	of characters with reverse
	       attribute as color.

       +rvc    This option enables the display of characters with reverse
	       attribute as color.

       -rw     This option indicates that reverse-wraparound should be
	       allowed.	 This allows the cursor	to back	up from	the leftmost
	       column of one line to the rightmost column of the previous
	       line.  This is very useful for editing long shell command lines
	       and is encouraged.  This	option can be turned on	and off	from
	       the VT Options menu.

       +rw     This option indicates that reverse-wraparound should not	be
	       allowed.

       -s      This option indicates that xterm	may scroll asynchronously,
	       meaning that the	screen does not	have to	be kept	completely up
	       to date while scrolling.	 This allows xterm to run faster when
	       network latencies are very high and is typically	useful when
	       running across a	very large internet or many gateways.

       +s      This option indicates that xterm	should scroll synchronously.

       -samename
	       Does not	send title and icon name change	requests when the
	       request would have no effect: the name is not changed.  This
	       has the advantage of preventing flicker and the disadvantage of
	       requiring an extra round	trip to	the server to find out the
	       previous	value.	In practice this should	never be a problem.

       +samename
	       Always send title and icon name change requests.

       -sb     This option indicates that some number of lines that are
	       scrolled	off the	top of the window should be saved and that a
	       scrollbar should	be displayed so	that those lines can be
	       viewed.	This option may	be turned on and off from the VT
	       Options menu.

       +sb     This option indicates that a scrollbar should not be displayed.

       -selbg color
	       This option specifies the color to use for the background of
	       selected	text.  If not specified, reverse video is used.	 See
	       the discussion of the highlightColor resource.

       -selfg color
	       This option specifies the color to use for selected text.  If
	       not specified, reverse video is used.  See the discussion of
	       the highlightTextColor resource.

       -sf     This option indicates that Sun function key escape codes	should
	       be generated for	function keys.

       +sf     This option indicates that the standard escape codes should be
	       generated for function keys.

       -sh number
	       scale line-height values	by the given number.  See the
	       discussion of the scaleHeight resource.

       -si     This option indicates that output to a window should not
	       automatically reposition	the screen to the bottom of the
	       scrolling region.  This option can be turned on and off from
	       the VT Options menu.

       +si     This option indicates that output to a window should cause it
	       to scroll to the	bottom.

       -sk     This option indicates that pressing a key while using the
	       scrollbar to review previous lines of text should cause the
	       window to be repositioned automatically in the normal position
	       at the bottom of	the scroll region.

       +sk     This option indicates that pressing a key while using the
	       scrollbar should	not cause the window to	be repositioned.

       -sl number
	       This option specifies the number	of lines to save that have
	       been scrolled off the top of the	screen.	 This corresponds to
	       the saveLines resource.	The default is "1024".

       -sm     This option, corresponding to the sessionMgt resource,
	       indicates that xterm should set up session manager callbacks.

       +sm     This option indicates that xterm	should not set up session
	       manager callbacks.

       -sp     This option indicates that Sun/PC keyboard should be assumed,
	       providing mapping for keypad "+"	to ",",	and CTRL-F1 to F13,
	       CTRL-F2 to F14, etc.

       +sp     This option indicates that the standard escape codes should be
	       generated for keypad and	function keys.

       -t      This option indicates that xterm	should start in	Tektronix
	       mode, rather than in VTxxx mode.	 Switching between the two
	       windows is done using the "Options" menus.

	       Terminal	database (terminfo (5) or termcap (5)) entries that
	       work with xterm are:

	       "tek4014",
	       "tek4015",
	       "tek4012",
	       "tek4013",
	       "tek4010", and
	       "dumb".

	       Xterm automatically searches the	terminal database in this
	       order for these entries and then	sets the "TERM"	variable (and
	       the "TERMCAP" environment variable, if relevant).

       +t      This option indicates that xterm	should start in	VTxxx mode.

       -tb     This option, corresponding to the toolBar resource, indicates
	       that xterm should display a toolbar (or menubar)	at the top of
	       its window.  The	buttons	in the toolbar correspond to the popup
	       menus, e.g., control/left/mouse for Main	Options.

       +tb     This option indicates that xterm	should not set up a toolbar.

       -ti term_id
	       Specify the name	used by	xterm to select	the correct response
	       to terminal ID queries.	It also	specifies the emulation	level,
	       used to determine the type of response to a DA control
	       sequence.  Valid	values include vt52, vt100, vt101, vt102,
	       vt220, and vt240	(the "vt" is optional).	 The default is
	       "vt420".	 The term_id argument specifies	the terminal ID	to
	       use.  (This is the same as the decTerminalID resource).

       -tm string
	       This option specifies a series of terminal setting keywords
	       followed	by the characters that should be bound to those
	       functions, similar to the stty program.	The keywords and their
	       values are described in detail in the ttyModes resource.

       -tn name
	       This option specifies the name of the terminal type to be set
	       in the TERM environment variable.  It corresponds to the
	       termName	resource.  This	terminal type must exist in the
	       terminal	database (termcap or terminfo, depending on how	xterm
	       is built) and should have li# and co# entries.  If the terminal
	       type is not found, xterm	uses the built-in list "xterm",
	       "vt102",	etc.

       -u8     This option sets	the utf8 resource.  When utf8 is set, xterm
	       interprets incoming data	as UTF-8.  This	sets the wideChars
	       resource	as a side-effect, but the UTF-8	mode set by this
	       option prevents it from being turned off.  If you must turn
	       UTF-8 encoding on and off, use the -wc option or	the
	       corresponding wideChars resource, rather	than the -u8 option.

	       This option and the utf8	resource are overridden	by the -lc and
	       -en options and locale resource.	 That is, if xterm has been
	       compiled	to support luit, and the locale	resource is not
	       "false" this option is ignored.	We recommend using the -lc
	       option or the "locale: true" resource in	UTF-8 locales when
	       your operating system supports locale, or -en UTF-8 option or
	       the "locale: UTF-8" resource when your operating	system does
	       not support locale.

       +u8     This option resets the utf8 resource.

       -uc     This option makes the cursor underlined instead of a box.

       +uc     This option makes the cursor a box instead of underlined.

       -ulc    This option disables the	display	of characters with underline
	       attribute as color rather than with underlining.

       +ulc    This option enables the display of characters with underline
	       attribute as color rather than with underlining.

       -ulit   This option, corresponding to the italicULMode resource,
	       disables	the display of characters with underline attribute as
	       italics rather than with	underlining.

       +ulit   This option, corresponding to the italicULMode resource,
	       enables the display of characters with underline	attribute as
	       italics rather than with	underlining.

       -ut     This option indicates that xterm	should not write a record into
	       the system utmp log file.

       +ut     This option indicates that xterm	should write a record into the
	       system utmp log file.

       -vb     This option indicates that a visual bell	is preferred over an
	       audible one.  Instead of	ringing	the terminal bell whenever a
	       Control-G is received, the window will be flashed.

       +vb     This option indicates that a visual bell	should not be used.

       -wc     This option sets	the wideChars resource.

	       When wideChars is set, xterm maintains internal structures for
	       16-bit characters.  If xterm is not started in UTF-8 mode (or
	       if this resource	is not set), initially it maintains those
	       structures to support 8-bit characters.	Xterm can later	be
	       switched, using a menu entry or control sequence, causing it to
	       reallocate those	structures to support 16-bit characters.

	       The default is "false".

       +wc     This option resets the wideChars	resource.

       -wf     This option indicates that xterm	should wait for	the window to
	       be mapped the first time	before starting	the subprocess so that
	       the initial terminal size settings and environment variables
	       are correct.  It	is the application's responsibility to catch
	       subsequent terminal size	changes.

       +wf     This option indicates that xterm	should not wait	before
	       starting	the subprocess.

       -ziconbeep percent
	       Same as zIconBeep resource.  If percent is non-zero, xterms
	       that produce output while iconified will	cause an XBell sound
	       at the given volume and have "***" prepended to their icon
	       titles.	Most window managers will detect this change
	       immediately, showing you	which window has the output.  (A
	       similar feature was in x10 xterm.)

       -C      This option indicates that this window should receive console
	       output.	This is	not supported on all systems.  To obtain
	       console output, you must	be the owner of	the console device,
	       and you must have read and write	permission for it.  If you are
	       running X under xdm on the console screen you may need to have
	       the session startup and reset programs explicitly change	the
	       ownership of the	console	device in order	to get this option to
	       work.

       -Sccn   This option allows xterm	to be used as an input and output
	       channel for an existing program and is sometimes	used in
	       specialized applications.  The option value specifies the last
	       few letters of the name of a pseudo-terminal to use in slave
	       mode, plus the number of	the inherited file descriptor.	If the
	       option contains a "/" character,	that delimits the characters
	       used for	the pseudo-terminal name from the file descriptor.
	       Otherwise, exactly two characters are used from the option for
	       the pseudo-terminal name, the remainder is the file descriptor.
	       Examples	(the first two are equivalent since the	descriptor
	       follows the last	"/"):

		   -S/dev/pts/123/45
		   -S123/45
		   -Sab34

	       Note that xterm does not	close any file descriptor which	it did
	       not open	for its	own use.  It is	possible (though probably not
	       portable) to have an application	which passes an	open file
	       descriptor down to xterm	past the initialization	or the -S
	       option to a process running in the xterm.

   Old Options
       The following command line arguments are	provided for compatibility
       with older versions.  They may not be supported in the next release as
       the X Toolkit provides standard options that accomplish the same	task.

       %geom   This option specifies the preferred size	and position of	the
	       Tektronix window.  It is	shorthand for specifying the
	       "tekGeometry" resource.

       #geom   This option specifies the preferred position of the icon
	       window.	It is shorthand	for specifying the "iconGeometry"
	       resource.

       -T string
	       This option specifies the title for xterm's windows.  It	is
	       equivalent to -title.

       -n string
	       This option specifies the icon name for xterm's windows.	 It is
	       shorthand for specifying	the "iconName" resource.  Note that
	       this is not the same as the toolkit option -name.  The default
	       icon name is the	application name.

	       If no suitable icon is found, xterm provides a compiled-in
	       pixmap.

	       X Toolkit sets the WM_ICON_NAME property	using this value.

       -r      This option indicates that reverse video	should be simulated by
	       swapping	the foreground and background colors.  It is
	       equivalent to -rv.

       -w number
	       This option specifies the width in pixels of the	border
	       surrounding the window.	It is equivalent to -borderwidth or
	       -bw.

   X Toolkit Options
       The following standard X	Toolkit	command	line arguments are commonly
       used with xterm:

       -bd color
	       This option specifies the color to use for the border of	the
	       window.	The corresponding resource name	is borderColor.	 Xterm
	       uses the	X Toolkit default, which is "XtDefaultForeground".

	       Xterm's VT100 window has	two borders: the inner border
	       internalBorder and the outer border borderWidth,	managed	by the
	       X Toolkit.

	       Normally	xterm fills the	inner border using the VT100 window's
	       background color.  If the colorInnerBorder resource is enabled,
	       then xterm may fill the inner border using the borderColor
	       resource.

       -bg color
	       This option specifies the color to use for the background of
	       the window.  The	corresponding resource name is background.
	       The default is "XtDefaultBackground".

       -bw number
	       This option specifies the width in pixels of the	border
	       surrounding the window.

	       This appears to be a legacy of older X releases.	 It sets the
	       borderWidth resource of the shell widget, and may provide
	       advice to your window manager to	set the	thickness of the
	       window frame.  Most window managers do not use this
	       information.  See the -b	option,	which controls the inner
	       border of the xterm window.

       -display	display
	       This option specifies the X server to contact; see X(1).

       -fg color
	       This option specifies the color to use for displaying text.
	       The corresponding resource name is foreground.  The default is
	       "XtDefaultForeground".

       -fn font
	       This option specifies the font to be used for displaying	normal
	       text.  The corresponding	resource name is font.	The resource
	       value default is	fixed.

       -font font
	       This is the same	as -fn.

       -geometry geometry
	       This option specifies the preferred size	and position of	the
	       VTxxx window; see X(1).

	       The normal geometry specification can be	suffixed with @
	       followed	by a Xinerama screen specification; it can be either g
	       for the global screen (default),	c for the current screen or a
	       screen number.

       -iconic
	       This option indicates that xterm	should ask the window manager
	       to start	it as an icon rather than as the normal	window.	 The
	       corresponding resource name is iconic.

       -name name
	       This option specifies the application name under	which
	       resources are to	be obtained, rather than the default
	       executable file name.  Name should not contain "." or "*"
	       characters.

       -rv     This option indicates that reverse video	should be simulated by
	       swapping	the foreground and background colors.  The
	       corresponding resource name is reverseVideo.

       +rv     Disable the simulation of reverse video by swapping foreground
	       and background colors.

       -title string
	       This option specifies the window	title string, which may	be
	       displayed by window managers if the user	so chooses.  It	is
	       shorthand for specifying	the "title" resource.  The default
	       title is	the command line specified after the -e	option,	if
	       any, otherwise the application name.

	       X Toolkit sets the WM_NAME property using this value.

       -xrm resourcestring
	       This option specifies a resource	string to be used.  This is
	       especially useful for setting resources that do not have
	       separate	command	line options.

       X Toolkit accepts alternate names for a few of these options, e.g.,

       o   "-background" for "-bg"

       o   "-font" for "-fn"

       o   "-foreground" for "-fg"

       Abbreviated options also	are supported, e.g., "-v" for "-verbose."

RESOURCES
       Xterm understands all of	the core X Toolkit resource names and classes.
       Application specific resources (e.g., "XTerm.NAME") follow:

   Application Resources
       backarrowKeyIsErase (class BackarrowKeyIsErase)
	       Tie the VTxxx backarrowKey and ptyInitialErase resources
	       together	by setting the DECBKM state according to whether the
	       initial erase character is a backspace (8) or delete (127)
	       character.  A "false" value disables this feature.  The default
	       is "False".

	       Here are	tables showing how the initial settings	for

	       o   backarrowKeyIsErase (BKIE),

	       o   backarrowKey	(BK), and

	       o   ptyInitialErase (PIE), along	with the

	       o   stty	erase character	(^H for	backspace, ^? for delete)

	       will affect DECBKM.  First, xterm obtains the initial erase
	       character:

	       o   xterm's internal value is ^H

	       o   xterm asks the operating system for the value which stty
		   shows

	       o   the ttyModes	resource may override erase

	       o   if ptyInitialErase is false,	xterm will look	in the
		   terminal database

	       Summarizing that	as a table:

	       PIE     stty   termcap	erase
	       -------------------------------
	       false	^H	^H	 ^H
	       false	^H	^?	 ^?
	       false	^?	^H	 ^H
	       false	^?	^?	 ^?
	       true	^H	^H	 ^H
	       true	^H	^?	 ^H
	       true	^?	^H	 ^?
	       true	^?	^?	 ^?

	       Using that erase	character, xterm allows	further	choices:

	       o   if backarrowKeyIsErase is true, xterm uses the erase
		   character for the initial state of DECBKM

	       o   if backarrowKeyIsErase is false, xterm sets DECBKM to 2
		   (internal).	This ties together backarrowKey	and the
		   control sequence for	DECBKM.

	       o   applications	can send a control sequence to set/reset
		   DECBKM control set

	       o   the "Backarrow Key (BS/DEL)"	menu entry toggles DECBKM

	       Summarizing the initialization details:

	       erase   BKIE    BK      DECBKM	result
	       ----------------------------------------
		^?     false   false	 2	  ^H
		^?     false   true	 2	  ^?
		^?     true    false	 0	  ^?
		^?     true    true	 1	  ^?
		^H     false   false	 2	  ^H
		^H     false   true	 2	  ^?
		^H     true    false	 0	  ^H
		^H     true    true	 1	  ^H

       buffered	(class Buffered)
	       Normally	xterm is built with double-buffer support.  This
	       resource	can be used to turn it on or off.  Setting the
	       resource	to "true" turns	double-buffering on.  The default
	       value is	"False".

       bufferedFPS (class BufferedFPS)
	       When xterm is built with	double-buffer support, this gives the
	       maximum number of frames/second.	 The default is	"40" and is
	       limited to the range 1 through 100.

       fullscreen (class Fullscreen)
	       Specifies whether or not	xterm should ask the window manager to
	       use a fullscreen	layout on startup.  Xterm accepts either a
	       keyword (ignoring case) or the number shown in parentheses:

	       false (0)
		  Fullscreen layout is not used	initially, but may be later
		  via menu-selection or	control	sequence.

	       true (1)
		  Fullscreen layout is used initially, but may be disabled
		  later	via menu-selection or control sequence.

	       always (2)
		  Fullscreen layout is used initially, and cannot be disabled
		  later	via menu-selection or control sequence.

	       never (3)
		  Fullscreen layout is not used, and cannot be enabled later
		  via menu-selection or	control	sequence.

	       The default is "false".

       hold (class Hold)
	       If true,	xterm will not immediately destroy its window when the
	       shell command completes.	 It will wait until you	use the	window
	       manager to destroy/kill the window, or if you use the menu
	       entries that send a signal, e.g., HUP or	KILL.  You may scroll
	       back, select text, etc.,	to perform most	graphical operations.
	       Resizing	the display will lose data, however, since this
	       involves	interaction with the shell which is no longer running.

       hpFunctionKeys (class HpFunctionKeys)
	       Specifies whether or not	HP function key	escape codes should be
	       generated for function keys.  The default is "false", i.e.,
	       this feature is disabled.

	       The keyboardType	resource is the	preferred mechanism for
	       selecting this mode.

       iconGeometry (class IconGeometry)
	       Specifies the preferred size and	position of the	application
	       when iconified.	It is not necessarily obeyed by	all window
	       managers.

       iconHint	(class IconHint)
	       Specifies an icon which will be added to	the window manager
	       hints.  Xterm provides no default value.

	       Set this	resource to "none" to omit the hint entirely, using
	       whatever	the window manager may decide.

	       If the iconHint resource	is given (or is	set via	the -n option)
	       xterm searches for a pixmap file	with that name,	in the current
	       directory as well as in /usr/local/share/pixmaps.  if the
	       resource	does not specify an absolute pathname.	In each	case,
	       xterm adds "_48x48" and/or ".xpm" to the	filename after trying
	       without those suffixes.	If it is able to load the file,	xterm
	       sets the	window manager hint for	the icon-pixmap.  These
	       pixmaps are distributed with xterm, and can optionally be
	       compiled-in:

	       o   mini.xterm_16x16, mini.xterm_32x32, mini.xterm_48x48

	       o   filled-xterm_16x16, filled-xterm_32x32, filled-xterm_48x48

	       o   xterm_16x16,	xterm_32x32, xterm_48x48

	       o   xterm-color_16x16, xterm-color_32x32, xterm-color_48x48

	       In either case, xterm allows for	adding a "_48x48" to specify
	       the largest of the pixmaps as a default.	 That is, "mini.xterm"
	       is the same as "mini.xterm_48x48".

	       If no explicit iconHint resource	is given (or if	none of	the
	       compiled-in names matches), xterm uses "mini.xterm" (which is
	       always compiled-in).

	       The iconHint resource has no effect on "desktop"	files,
	       including "panel" and "menu".  Those are	typically set via a
	       ".desktop" file;	xterm provides samples for itself (and the
	       uxterm script).	The more capable desktop systems allow
	       changing	the icon on a per-user basis.

       iconName	(class IconName)
	       Specifies a label for xterm when	iconified.  Xterm provides no
	       default value; some window managers may assume the application
	       name, e.g., "xterm".

	       Setting the iconName resource sets the icon label unless
	       overridden by zIconBeep or the control sequences	which change
	       the window and icon labels.

       keyboardType (class KeyboardType)
	       Enables one (or none) of	the various keyboard-type resources:
	       hpFunctionKeys, scoFunctionKeys,	sunFunctionKeys,
	       tcapFunctionKeys, oldXtermFKeys and sunKeyboard.

	       The resource's value should be one of the corresponding strings
	       "hp", "sco", "sun", "tcap", "legacy" or "vt220",	respectively.

	       The individual resources	are provided for legacy	support; this
	       resource	is simpler to use.  Xterm will use only	one keyboard-
	       type, but if multiple resources are set,	it warns and uses the
	       last one	it checks.

	       The default is "unknown", i.e., none of the associated
	       resources are set via this resource.

       maxBufSize (class MaxBufSize)
	       Specify the maximum size	of the input buffer.  The default is
	       "32768".	 You cannot set	this to	a value	less than the
	       minBufSize resource.  It	will be	increased as needed to make
	       that value evenly divide	this one.

	       On some systems you may want to increase	one or both of the
	       maxBufSize and minBufSize resource values to achieve better
	       performance if the operating system prefers larger buffer
	       sizes.

       maximized (class	Maximized)
	       Specifies whether or not	xterm should ask the window manager to
	       maximize	its layout on startup.	The default is "false".

       menuHeight (class MenuHeight)
	       Specifies the height of the toolbar, which may be increased by
	       the X toolkit layout widget depending upon the fontsize used.
	       The default is "25".

       messages	(class Messages)
	       Specifies whether write access to the terminal is allowed
	       initially.  See mesg(1).	 The default is	"true".

       menuLocale (class MenuLocale)
	       Specify the locale used for character-set computations when
	       loading the popup menus.	 Use this to improve initialization
	       performance of the Athena popup menus, which may	load
	       unnecessary (and	very large) fonts, e.g., in a locale having
	       UTF-8 encoding.	The default is "C" (POSIX).

	       To use the current locale (only useful if you have localized
	       the resource settings for the menu entries), set	the resource
	       to an empty string.

       minBufSize (class MinBufSize)
	       Specify the minimum size	of the input buffer, i.e., the amount
	       of data that xterm requests on each read.  The default is
	       "4096".	You cannot set this to a value less than 64.

       omitTranslation (class OmitTranslation)
	       Selectively omit	one or more parts of xterm's default
	       translations at startup.	 The resource value is a comma-
	       separated list of keywords, which may be	abbreviated:

	       default
		      ignore (mouse) button-down events	which were not handled
		      by other translations

	       fullscreen
		      assigns a	key-binding to the fullscreen()	action.

	       keypress
		      assigns keypresses by default to the insert-seven-bit()
		      and insert-eight-bit() actions.

	       paging assigns key bindings to the scroll-back()	and scroll-
		      forw() actions.

	       popup-menu
		      assigns mouse-buttons with the control modifier to the
		      popup-menus.

	       reset  assigns mouse-button 2 with the meta modifier to the
		      clear-saved-lines	action.

	       scroll-lock
		      assigns a	key-binding to the scroll-lock() action.

	       select assigns mouse- and keypress-combinations to actions
		      which manipulate the selection.

	       shift-fonts
		      assigns key-bindings to larger-vt-font() and smaller-vt-
		      font() actions.

	       wheel-mouse
		      assigns buttons 4	and 5 with different modifiers to the
		      scroll-back() and	scroll-forw() actions.

       ptyHandshake (class PtyHandshake)
	       If "true", xterm	will perform handshaking during	initialization
	       to ensure that the parent and child processes update the	utmp
	       and stty	state.

	       See also	waitForMap which waits for the pseudo-terminal's
	       notion of the screen size, and ptySttySize which	resets the
	       screen size after other terminal	initialization is complete.
	       The default is "true".

       ptyInitialErase (class PtyInitialErase)
	       If "true", xterm	will use the pseudo-terminal's sense of	the
	       stty erase value.  If "false", xterm will set the stty erase
	       value to	match its own configuration, using the kb string from
	       the termcap entry as a reference, if available.

	       In either case, the result is applied to	the TERMCAP variable
	       which xterm sets, if the	system uses TERMCAP.

	       See also	the ttyModes resource, which may override this.	 The
	       default is "False".

       ptySttySize (class PtySttySize)
	       If "true", xterm	will reset the screen size after terminal
	       initialization is complete.  This is needed for some systems
	       whose pseudo-terminals cannot propagate terminal
	       characteristics.	 Where it is not needed, it can	interfere with
	       other methods for setting the initial screen size, e.g.,	via
	       window manager interaction.

	       See also	waitForMap which waits for a handshake-message giving
	       the pseudo-terminal's notion of the screen size.	 The default
	       is "false" on Linux and macOS systems, "true" otherwise.

       reportColors (class ReportColors)
	       If true,	xterm will print to the	standard output	a summary of
	       colors as it allocates them.  The default is "false".

       reportFonts (class ReportFonts)
	       If true,	xterm will print to the	standard output	a summary of
	       each font's metrics (size, number of glyphs, etc.), as it loads
	       them.  The default is "false".

       reportIcons (class ReportIcons)
	       If true,	xterm will print to the	standard output	a summary of
	       each pixmap icon	as it loads them.  The default is "false".

       reportXRes (class ReportXRes)
	       If true,	xterm will print to the	standard output	a list of the
	       boolean,	numeric	and string X resources for the VT100 widget
	       after initialization.  The default is "false".

       sameName	(class SameName)
	       If the value of this resource is	"true",	xterm does not send
	       title and icon name change requests when	the request would have
	       no effect: the name is not changed.  This has the advantage of
	       preventing flicker and the disadvantage of requiring an extra
	       round trip to the server	to find	out the	previous value.	 In
	       practice	this should never be a problem.	 The default is
	       "true".

       scaleHeight (class ScaleHeight)
	       Scale line-height values	by the resource	value, which is
	       limited to "0.9"	to "1.5".  The default value is	"1.0",

	       While this resource applies to either bitmap or TrueType	fonts,
	       its main	purpose	is to help work	around incompatible changes in
	       the Xft library's font metrics.	Xterm checks the font metrics
	       to find what the	library	claims are the bounding	boxes for each
	       glyph (character).  However, some of Xft's features (such as
	       the autohinter) can cause the glyphs to be scaled larger	than
	       the bounding boxes, and be partly overwritten by	the next row.

	       See useClipping for a related resource.

       scoFunctionKeys (class ScoFunctionKeys)
	       Specifies whether or not	SCO function key escape	codes should
	       be generated for	function keys.	The default is "false",	i.e.,
	       this feature is disabled.

	       The keyboardType	resource is the	preferred mechanism for
	       selecting this mode.

       sessionMgt (class SessionMgt)
	       If the value of this resource is	"true",	xterm sets up session
	       manager callbacks for XtNdieCallback and	XtNsaveCallback.  The
	       default is "true".

       sunFunctionKeys (class SunFunctionKeys)
	       Specifies whether or not	Sun function key escape	codes should
	       be generated for	function keys.	The default is "false",	i.e.,
	       this feature is disabled.

	       The keyboardType	resource is the	preferred mechanism for
	       selecting this mode.

       sunKeyboard (class SunKeyboard)
	       Xterm translates	certain	key symbols based on its assumptions
	       about your keyboard.  This resource specifies whether or	not
	       Sun/PC keyboard layout (i.e., the PC keyboard's numeric keypad
	       together	with 12	function keys) should be assumed rather	than
	       DEC VT220.  This	causes the keypad "+" to be mapped to ",".
	       and CTRL	F1-F10 to F11-F20, depending on	the setting of the
	       ctrlFKeys resource, so xterm emulates a DEC VT220 more
	       accurately.  Otherwise (the default, with sunKeyboard set to
	       "false"), xterm uses PC-style bindings for the function keys
	       and keypad.

	       PC-style	bindings use the Shift,	Alt, Control and Meta keys as
	       modifiers for function-keys and keypad (see Xterm Control
	       Sequences for details).	The PC-style bindings are analogous to
	       PCTerm, but not the same	thing.	Normally these bindings	do not
	       conflict	with the use of	the Meta key as	described for the
	       eightBitInput resource.	If they	do, note that the PC-style
	       bindings	are evaluated first.

	       See also	the keyboardType resource.

       tcapFunctionKeys	(class TcapFunctionKeys)
	       Specifies whether or not	function key escape codes read from
	       the termcap/terminfo entry corresponding	to the TERM
	       environment variable should be generated	for function keys
	       instead of those	configured using sunKeyboard and keyboardType.
	       The default is "false", i.e., this feature is disabled.

	       The keyboardType	resource is the	preferred mechanism for
	       selecting this mode.

       termName	(class TermName)
	       Specifies the terminal type name	to be set in the TERM
	       environment variable.

       title (class Title)
	       Specifies a string that may be used by the window manager when
	       displaying this application.

       toolBar (class ToolBar)
	       Specifies whether or not	the toolbar should be displayed.  The
	       default is "true".

       ttyModes	(class TtyModes)
	       Specifies a string containing terminal setting keywords.
	       Except where noted, they	may be bound to	characters.  Other
	       keywords	set modes.  Not	all keywords are supported on a	given
	       system.	Allowable keywords include:

	       Keyword	 POSIX?	  Notes
	       ----------------------------------------------------------------
	       brk	 no	  CHAR may send	an "interrupt" signal, as well
				  as ending the	input-line.
	       dsusp	 no	  CHAR will send a terminal "stop" signal
				  after	input is flushed.
	       eof	 yes	  CHAR will terminate input (i.e., an end of
				  file).
	       eol	 yes	  CHAR will end	the line.
	       eol2	 no	  alternate CHAR for ending the	line.
	       erase	 yes	  CHAR will erase the last character typed.
	       erase2	 no	  alternate CHAR for erasing the last input-
				  character.
	       flush	 no	  CHAR will cause output to be discarded until
				  another flush	character is typed.
	       intr	 yes	  CHAR will send an "interrupt"	signal.
	       kill	 yes	  CHAR will erase the current line.
	       lnext	 no	  CHAR will enter the next character quoted.
	       quit	 yes	  CHAR will send a "quit" signal.
	       rprnt	 no	  CHAR will redraw the current line.
	       start	 yes	  CHAR will restart the	output after stopping
				  it.
	       status	 no	  CHAR will cause a system-generated status
				  line to be printed.
	       stop	 yes	  CHAR will stop the output.
	       susp	 yes	  CHAR will send a terminal "stop" signal
	       swtch	 no	  CHAR will switch to a	different shell	layer.
	       tabs	 yes	  Mode disables	tab-expansion.
	       -tabs	 yes	  Mode enables tab-expansion.
	       weras	 no	  CHAR will erase the last word	typed.

	       Control characters may be specified as ^char (e.g., ^c or ^u)
	       and ^? may be used to indicate delete (127).  Use ^- to denote
	       undef.  Use \034	to represent ^\, since a literal backslash in
	       an X resource escapes the next character.

	       This is very useful for overriding the default terminal
	       settings	without	having to run stty every time an xterm is
	       started.	 Note, however,	that the stty program on a given host
	       may use different keywords; xterm's table is built in.  The
	       POSIX column in the table indicates which keywords are
	       supported by a standard stty program.

	       If the ttyModes resource	specifies a value for erase, that
	       overrides the ptyInitialErase resource setting, i.e., xterm
	       initializes the terminal	to match that value.

       useInsertMode (class UseInsertMode)
	       Force use of insert mode	by adding appropriate entries to the
	       TERMCAP environment variable.  This is useful if	the system
	       termcap is broken.  (This resource is ignored on	most systems,
	       because TERMCAP is not used).  The default is "false".

       utmpDisplayId (class UtmpDisplayId)
	       Specifies whether or not	xterm should try to record the display
	       identifier (display number and screen number) as	well as	the
	       hostname	in the system utmp log file.  The default is "true".

       utmpInhibit (class UtmpInhibit)
	       Specifies whether or not	xterm should try to record the user's
	       terminal	in the system utmp log file.  If true, xterm will not
	       try.  The default is "false".

       validShells (class ValidShells)
	       Augment (add to)	the system's /etc/shells, when determining
	       whether to set the "SHELL" environment variable when running a
	       given program.

	       The resource value is a list of lines (separated	by newlines).
	       Each line holds one pathname.  Xterm ignores any	line beginning
	       with "#"	after trimming leading/trailing	whitespace from	each
	       line.

	       The default is an empty string.

       waitForMap (class WaitForMap)
	       Specifies whether or not	xterm should wait for the initial
	       window map before starting the subprocess.  This	is part	of the
	       ptyHandshake logic.  When xterm is directed to wait in this
	       fashion,	it passes the terminal size from the display end of
	       the pseudo-terminal to the terminal I/O connection, e.g., using
	       the size	according to the window	manager.  Otherwise, it	uses
	       the size	as given in resource values or command-line option
	       -geometry.  The default is "false".

       zIconBeep (class	ZIconBeep)
	       Same as -ziconbeep command line argument.  If the value of this
	       resource	is non-zero, xterms that produce output	while
	       iconified will cause an XBell sound at the given	volume and
	       have "*** " prepended to	their icon titles.  Most window
	       managers	will detect this change	immediately, showing you which
	       window has the output.  (A similar feature was in x10 xterm.)
	       The default is "false".

       zIconTitleFormat	(class ZIconTitleFormat)
	       Allow customization of the string used in the zIconBeep
	       feature.	 The default value is "*** %s".

	       If the resource value contains a	"%s", then xterm inserts the
	       icon title at that point	rather than prepending the string to
	       the icon	title.	(Only the first	"%s" is	used).

   VT100 Widget	Resources
       The following resources are specified as	part of	the vt100 widget
       (class VT100).  They are	specified by patterns such as
       "XTerm.vt100.NAME".

       If your xterm is	configured to support the "toolbar", then those
       patterns	need an	extra level for	the form-widget	which holds the
       toolbar and vt100 widget.  A wildcard between the top-level "XTerm" and
       the "vt100" widget makes	the resource settings work for either, e.g.,
       "XTerm*vt100.NAME".

       activeIcon (class ActiveIcon)
	       Specifies whether or not	active icon windows are	to be used
	       when the	xterm window is	iconified, if this feature is compiled
	       into xterm.  The	active icon is a miniature representation of
	       the content of the window and will update as the	content
	       changes.	 Not all window	managers necessarily support
	       application icon	windows.  Some window managers will allow you
	       to enter	keystrokes into	the active icon	window.	 The default
	       is "default".

	       Xterm accepts either a keyword (ignoring	case) or the number
	       shown in	parentheses:

	       false (0)
		      No active	icon is	shown.

	       true (1)
		      The active icon is shown.	 If you	are using twm, use
		      this setting to enable active-icons.

	       default (2)
		      Xterm checks at startup, and shows an active icon	only
		      for window managers which	it can identify	and which are
		      known to support the feature.  These are fvwm (full
		      support),	and window maker (limited).  A few other
		      windows managers (such as	twm and	ctwm) support active
		      icons, but do not	support	the extensions which allow
		      xterm to identify	the window manager.

       allowBoldFonts (class AllowBoldFonts)
	       When set	to "false", xterm will not use bold fonts.  This
	       overrides both the alwaysBoldMode and the boldMode resources.

       allowC1Printable	(class AllowC1Printable)
	       If true,	overrides the mapping of C1 controls (codes 128-159)
	       to make them be treated as if they were printable characters.
	       Although	this corresponds to no particular standard, some users
	       insist it is a VT100.  The default is "false".

       allowColorOps (class AllowColorOps)
	       Specifies whether control sequences that	set/query the dynamic
	       colors should be	allowed.  ANSI colors are unaffected by	this
	       resource	setting.  The default is "true".

       allowFontOps (class AllowFontOps)
	       Specifies whether control sequences that	set/query the font
	       should be allowed.  The default is "true".

       allowMouseOps (class AllowMouseOps)
	       Specifies whether control sequences that	enable xterm to	send
	       escape sequences	to the host on mouse-clicks and	movement.  The
	       default is "true".

       allowPasteControls (class AllowPasteControls)
	       If true,	allow control characters such as BEL and CAN to	be
	       pasted.	Formatting characters (tab, newline) are always
	       allowed.	 Other C0 control characters are suppressed unless
	       this resource is	enabled.  The exact set	of control characters
	       (C0 and C1) depends upon	whether	UTF-8 encoding is used,	as
	       well as the allowC1Printable resource.  The default is "false".

       allowScrollLock (class AllowScrollLock)
	       Specifies whether control sequences that	set/query the Scroll
	       Lock key	should be allowed, as well as whether the Scroll Lock
	       key responds to user's keypress.	 The default is	"false".

	       When this feature is enabled, xterm will	sense the state	of the
	       Scroll Lock key each time it acquires focus.  Pressing the
	       Scroll Lock key toggles xterm's internal	state, as well as
	       toggling	the associated LED.  While the Scroll Lock is active,
	       xterm attempts to keep a	viewport on the	same set of lines.  If
	       the current viewport is scrolled	past the limit set by the
	       saveLines resource, then	Scroll Lock has	no further effect.

	       The reason for setting the default to "false" is	to avoid user
	       surprise.  This key is generally	unused in keyboard
	       configurations, and has not acquired a standard meaning even
	       when it is used in that manner.	Consequently, users have
	       assigned	it for ad hoc purposes.

       allowSendEvents (class AllowSendEvents)
	       Specifies whether or not	synthetic key and button events
	       (generated using	the X protocol SendEvent request) should be
	       interpreted or discarded.  The default is "false" meaning they
	       are discarded.  Note that allowing such events would create a
	       very large security hole, therefore enabling this resource
	       forcefully disables the allowXXXOps resources.  The default is
	       "false".

       allowTcapOps (class AllowTcapOps)
	       Specifies whether control sequences that	query the terminal's
	       notion of its function-key strings, as termcap or terminfo
	       capabilities should be allowed.	The default is "true".

	       A few programs, e.g., vim, use this feature to get an accurate
	       description of the terminal's capabilities, independent of the
	       termcap/terminfo	setting:

	       o   Xterm can tell the querying program how many	colors it
		   supports.  This is a	constant, depending on how it is
		   compiled, typically 16.  It does not	change if you alter
		   resource settings, e.g., the	boldColors resource.

	       o   Xterm can tell the querying program what strings are	sent
		   by modified (shift-,	control-, alt-)	function- and keypad-
		   keys.  Reporting control- and alt-modifiers is a feature
		   that	relies on the ncurses extended naming.

       allowTitleOps (class AllowTitleOps)
	       Specifies whether control sequences that	modify the window
	       title or	icon name should be allowed.  The default is "true".

       allowWindowOps (class AllowWindowOps)
	       Specifies whether extended window control sequences (as used in
	       dtterm) should be allowed.  These include several control
	       sequences which manipulate the window size or position, as well
	       as reporting these values and the title or icon name.  Each of
	       these can be abused in a	script;	curiously enough most terminal
	       emulators that implement	these restrict only a small part of
	       the repertoire.	For fine-tuning, see disallowedWindowOps.  The
	       default is "false".

       altIsNotMeta (class AltIsNotMeta)
	       If "true", treat	the Alt-key as if it were the Meta-key.	 Your
	       keyboard	may happen to be configured so they are	the same.  But
	       if they are not,	this allows you	to use the same	prefix-	and
	       shifting	operations with	the Alt-key as with the	Meta-key.  See
	       altSendsEscape and metaSendsEscape.  The	default	is "false".

       altSendsEscape (class AltSendsEscape)
	       This is an additional keyboard operation	that may be processed
	       after the logic for metaSendsEscape.  It	is only	available if
	       the altIsNotMeta	resource is set.

	       o   If "true", Alt characters (a	character combined with	the
		   modifier associated with left/right Alt-keys) are converted
		   into	a two-character	sequence with the character itself
		   preceded by ESC.  This applies as well to function key
		   control sequences, unless xterm sees	that Alt is used in
		   your	key translations.

	       o   If "false", Alt characters input from the keyboard cause a
		   shift to 8-bit characters (just like	metaSendsEscape).  By
		   combining the Alt- and Meta-modifiers, you can create
		   corresponding combinations of ESC-prefix and	8-bit
		   characters.

	       The default is "False".	Xterm provides a menu option for
	       toggling	this resource.

       alternateScroll (class ScrollCond)
	       If "true", the scroll-back and scroll-forw actions send
	       cursor-up and -down keys	when xterm is displaying the alternate
	       screen.	The default is "false".

	       The alternateScroll state can also be set using a control
	       sequence.

       alwaysBoldMode (class AlwaysBoldMode)
	       Specifies whether xterm should check if the normal and bold
	       fonts are distinct before deciding whether to use overstriking
	       to simulate bold	fonts.	If this	resource is true, xterm	does
	       not make	the check for distinct fonts when deciding how to
	       handle the boldMode resource.  The default is "false".

	       boldMode	  alwaysBoldMode   Comparison	Action
	       ----------------------------------------------------
	       false	  false		   ignored	use font
	       false	  true		   ignored	use font
	       true	  false		   same		overstrike
	       true	  false		   different	use font
	       true	  true		   ignored	overstrike

	       This resource is	used only for bitmap fonts:

	       o   When	using bitmap fonts, it is possible that	the font
		   server will approximate the bold font by rescaling it from
		   a different font size than expected.	 The alwaysBoldMode
		   resource allows the user to override	the (sometimes poor)
		   resulting bold font with overstriking (which	is at least
		   consistent).

	       o   The problem does not	occur with TrueType fonts (though
		   there can be	other unnecessary issues such as different
		   coverage of the normal and bold fonts).

	       As an alternative, setting the allowBoldFonts resource to false
	       overrides both the alwaysBoldMode and the boldMode resources.

       alwaysHighlight (class AlwaysHighlight)
	       Specifies whether or not	xterm should always display a
	       highlighted text	cursor.	 By default (if	this resource is
	       false), a hollow	text cursor is displayed whenever the pointer
	       moves out of the	window or the window loses the input focus.
	       The default is "false".

       alwaysUseMods (class AlwaysUseMods)
	       Override	the numLock resource, telling xterm to use the Alt and
	       Meta modifiers to construct parameters for function key
	       sequences even if those modifiers appear	in the translations
	       resource.  Normally xterm checks	if Alt or Meta is used in a
	       translation that	would conflict with function key modifiers,
	       and will	ignore these modifiers in that special case.  The
	       default is "false".

       answerbackString	(class AnswerbackString)
	       Specifies the string that xterm sends in	response to an ENQ
	       (control/E) character from the host.  The default is a blank
	       string, i.e., "".  A hardware VT100 implements this feature as
	       a setup option.

       appcursorDefault	(class AppcursorDefault)
	       If "true", the cursor keys are initially	in application mode.
	       This is the same	as the VT102 private DECCKM mode, The default
	       is "false".

       appkeypadDefault	(class AppkeypadDefault)
	       If "true", the keypad keys are initially	in application mode.
	       The default is "false".

       assumeAllChars (class AssumeAllChars)
	       If "true", this enables a special case in bitmap	fonts to allow
	       the font	server to choose how to	display	missing	glyphs.	 The
	       default is "true".

	       The reason for this resource is to help with certain quasi-
	       automatically generated fonts (such as the ISO-10646-1 encoding
	       of Terminus) which have incorrect font-metrics.

       autoWrap	(class AutoWrap)
	       Specifies whether or not	auto-wraparound	should be enabled.
	       This is the same	as the VT102 DECAWM.  The default is "true".

       awaitInput (class AwaitInput)
	       Specifies whether or not	xterm uses a 50	millisecond timeout to
	       await input (i.e., to support the Xaw3d arrow scrollbar).  The
	       default is "false".

       backarrowKey (class BackarrowKey)
	       Specifies whether the backarrow key transmits a backspace (8)
	       or delete (127) character.  This	corresponds to the DECBKM
	       control sequence.  A "true" value specifies backspace.  The
	       default is "True".  Pressing the	control	key toggles this
	       behavior.

       background (class Background)
	       Specifies the color to use for the background of	the window.
	       The default is "XtDefaultBackground".

       bellIsUrgent (class BellIsUrgent)
	       Specifies whether to set	the Urgency hint for the window
	       manager when making a bell sound.  The default is "false".

       bellOnReset (class BellOnReset)
	       Specifies whether to sound a bell when doing a hard reset.  The
	       default is "true".

       bellSuppressTime	(class BellSuppressTime)
	       Number of milliseconds after a bell command is sent during
	       which additional	bells will be suppressed.  Default is 200.  If
	       set non-zero, additional	bells will also	be suppressed until
	       the server reports that processing of the first bell has	been
	       completed; this feature is most useful with the visible bell.

       boldColors (class ColorMode)
	       Specifies whether to combine bold attribute with	colors like
	       the IBM PC, i.e., map colors 0 through 7	to colors 8 through
	       15.  These normally are the brighter versions of	the first 8
	       colors, hence bold.  The	default	is "true".

       boldFont	(class BoldFont)
	       Specifies the name of the bold font to use instead of
	       overstriking.  There is no default for this resource.

	       This font must be the same height and width as the normal font,
	       otherwise it is ignored.	 If only one of	the normal or bold
	       fonts is	specified, it will be used as the normal font and the
	       bold font will be produced by overstriking this font.

	       See also	the discussion of boldMode and alwaysBoldMode
	       resources.

       boldMode	(class BoldMode)
	       This specifies whether or not text with the bold	attribute
	       should be overstruck to simulate	bold fonts if the resolved
	       bold font is the	same as	the normal font.  It may be desirable
	       to disable bold fonts when color	is being used for the bold
	       attribute.

	       Note that xterm has one bold font which you may set explicitly.
	       Xterm attempts to derive	a bold font for	the other font
	       selections (font1 through font6).  If it	cannot find a bold
	       font, it	will use the normal font.  In each case	(whether the
	       explicit	resource or the	derived	font), if the normal and bold
	       fonts are distinct, this	resource has no	effect.	 The default
	       is "true".

	       See the alwaysBoldMode resource which can modify	the behavior
	       of this resource.

	       Although	xterm attempts to derive a bold	font for other font
	       selections, the font server may not cooperate.  Since X11R6,
	       bitmap fonts have been scaled.  The font	server claims to
	       provide the bold	font that xterm	requests, but the result is
	       not always readable.  XFree86 introduced	a feature which	can be
	       used to suppress	the scaling.  In the X server's	configuration
	       file (e.g., "/etc/X11/XFree86" or "/etc/X11/xorg.conf"),	you
	       can add ":unscaled" to the end of the directory specification
	       for the "misc" fonts, which comprise the	fixed-pitch fonts that
	       are used	by xterm.  For example

		   FontPath		    "/usr/lib/X11/fonts/misc/"

	       would become

		   FontPath		    "/usr/lib/X11/fonts/misc/:unscaled"

	       Depending on your configuration,	the font server	may have its
	       own configuration file.	The same ":unscaled" can be added to
	       its configuration file at the end of the	directory
	       specification for "misc".

	       The bitmap scaling feature is also used by xterm	to implement
	       VT102 double-width and double-height characters.

       brokenLinuxOSC (class BrokenLinuxOSC)
	       If true,	xterm applies a	workaround to ignore malformed control
	       sequences that a	Linux script might send.  Compare the palette
	       control sequences documented in console_codes with ECMA-48.
	       The default is "true".

       brokenSelections	(class BrokenSelections)
	       If true,	xterm in 8-bit mode will interpret STRING selections
	       as carrying text	in the current locale's	encoding.  Normally
	       STRING selections carry ISO-8859-1 encoded text.	 Setting this
	       resource	to "true" violates the ICCCM; it may, however, be
	       useful for interacting with some	broken X clients.  The default
	       is "false".

       brokenStringTerm	(class BrokenStringTerm)
	       provides	a work-around for some ISDN routers which start	an
	       application control string without completing it.  Set this to
	       "true" if xterm appears to freeze when connecting.  The default
	       is "false".

	       Xterm's state parser recognizes several types of	control
	       strings which can contain text, e.g.,

	       APC (Application	Program	Command),
	       DCS (Device Control String),
	       OSC (Operating System Command),
	       PM (Privacy Message), and
	       SOS (Start of String),

	       Each should end with a string-terminator	(a special character
	       which cannot appear in these strings).  Ordinary	control
	       characters found	within the string are not ignored; they	are
	       processed without interfering with the process of accumulating
	       the control string's content.  Xterm recognizes these controls
	       in all modes, although some of the functions may	be suppressed
	       after parsing the control.

	       When enabled, this feature allows the user to exit from an
	       unterminated control string when	any of these ordinary control
	       characters are found:

	       control/D (used as an end of file in many shells),
	       control/H (backspace),
	       control/I (tab-feed),
	       control/J (line feed aka	newline),
	       control/K (vertical tab),
	       control/L (form feed),
	       control/M (carriage return),
	       control/N (shift-out),
	       control/O (shift-in),
	       control/Q (XOFF),
	       control/X (cancel)

       c132 (class C132)
	       Specifies whether or not	the VT102 DECCOLM escape sequence,
	       used to switch between 80 and 132 columns, should be honored.
	       The default is "false".

       cacheDoublesize (class CacheDoublesize)
	       Tells whether to	cache double-sized fonts by xterm.  Set	this
	       to zero to disable double-sized fonts altogether.

       cdXtraScroll (class CdXtraScroll)
	       Specifies whether xterm should scroll to	a new page when
	       clearing	the whole screen.  Like	tiXtraScroll, the intent of
	       this option is to provide a picture of the full-screen
	       application's display on	the scrollback before wiping out the
	       text.  The default for this resource is "false".

       charClass (class	CharClass)
	       Specifies comma-separated lists of character class bindings of
	       the form

		   low[-high][:value].

	       These are used in determining which sets	of characters should
	       be treated the same when	doing cut and paste.  See the
	       CHARACTER CLASSES section.

       checksumExtension (class	ChecksumExtension)
	       DEC VT420 and up	support	a control sequence DECRQCRA which
	       reports the checksum of the characters in a rectangle.  Xterm
	       supports	this, with extensions that can be configured with bits
	       of the checksumExtension:

	       0    do not negate the result.

	       1    do not report the VT100 video attributes.

	       2    do not omit	checksum for blanks.

	       3    omit checksum for cells not	explicitly initialized.

	       4    do not mask	cell value to 8	bits or	ignore combining
		    characters.

	       5    do not mask	cell value to 7	bits.

	       With the	default	value (0), xterm matches the behavior of DEC's
	       terminals.  To use all extensions, set all bits,	"-1" for
	       example.

       cjkWidth	(class CjkWidth)
	       Specifies whether xterm should follow the traditional East
	       Asian width convention.	When turned on,	characters with	East
	       Asian Ambiguous (A) category in UTR 11 have a column width of
	       2.  You may have	to set this option to "true" if	you have some
	       old East	Asian terminal based programs that assume that line-
	       drawing characters have a column	width of 2.  If	this resource
	       is false, the mkWidth resource controls the choice between the
	       system's	wcwidth	and xterm's built-in tables.  The default is
	       "false".

       color0 (class Color0)

       color1 (class Color1)

       color2 (class Color2)

       color3 (class Color3)

       color4 (class Color4)

       color5 (class Color5)

       color6 (class Color6)

       color7 (class Color7)
	       These specify the colors	for the	ISO-6429 extension.  The
	       defaults	are, respectively, black, red3,	green3,	yellow3, a
	       customizable dark blue, magenta3, cyan3,	and gray90.  The
	       default shades of color are chosen to allow the colors 8-15 to
	       be used as brighter versions.

       color8 (class Color8)

       color9 (class Color9)

       color10 (class Color10)

       color11 (class Color11)

       color12 (class Color12)

       color13 (class Color13)

       color14 (class Color14)

       color15 (class Color15)
	       These specify the colors	for the	ISO-6429 extension if the bold
	       attribute is also enabled.  The default resource	values are
	       respectively, gray50, red, green, yellow, a customized light
	       blue, magenta, cyan, and	white.

       color16 (class Color16)

       through

       color255	(class Color255)
	       These specify the colors	for the	256-color extension.  The
	       default resource	values are for

	       o   colors 16 through 231 to make a 6x6x6 color cube, and

	       o   colors 232 through 255 to make a grayscale ramp.

	       Resources past color15 are available as a compile-time option.
	       Due to a	hardcoded limit	in the X libraries on the total	number
	       of resources (to	400), the resources for	256-colors are omitted
	       when wide-character support and luit are	enabled.  Besides
	       inconsistent behavior if	only part of the resources were
	       allowed,	determining the	exact cutoff is	difficult, and the X
	       libraries tend to crash if the number of	resources exceeds the
	       limit.  The color palette is still initialized to the same
	       default values, and can be modified via control sequences.

	       On the other hand, the resource limit does permit including the
	       entire range for	88-colors.

       colorAttrMode (class ColorAttrMode)
	       Specifies whether colorBD, colorBL, colorRV, and	colorUL	should
	       override	ANSI colors.  If not, these are	displayed only when no
	       ANSI colors have	been set for the corresponding position.  The
	       default is "false".

       colorBD (class ColorBD)
	       This specifies the color	to use to display bold characters if
	       the "colorBDMode" resource is enabled.  The default is
	       "XtDefaultForeground".

	       See also	the veryBoldColors resource which allows combining
	       bold and	color.

       colorBDMode (class ColorAttrMode)
	       Specifies whether characters with the bold attribute should be
	       displayed in color or as	bold characters.  Note that setting
	       colorMode off disables all colors, including bold.  The default
	       is "false".

       colorBL (class ColorBL)
	       This specifies the color	to use to display blink	characters if
	       the "colorBLMode" resource is enabled.  The default is
	       "XtDefaultForeground".

	       See also	the veryBoldColors resource which allows combining
	       underline and color.

       colorBLMode (class ColorAttrMode)
	       Specifies whether characters with the blink attribute should be
	       displayed in color.  Note that setting colorMode	off disables
	       all colors, including this.  The	default	is "false".

       colorIT (class ColorIT)
	       This specifies the color	to use to display italic characters if
	       the "colorITMode" resource is enabled.  The default is
	       "XtDefaultForeground".

	       See also	the veryBoldColors resource which allows combining
	       attributes and color.

       colorITMode (class ColorAttrMode)
	       Specifies whether characters with the italic attribute should
	       be displayed in color or	as italic characters.  The default is
	       "false".

	       Note that:

	       o   Setting colorMode off disables all colors, including
		   italic.

	       o   The italicULMode resource overrides colorITMode.

       colorInnerBorder	(class ColorInnerBorder)
	       Normally, xterm fills the VT100 window's	inner border using the
	       background color.

	       If the colorInnerBorder resource	is enabled, at startup xterm
	       will compare the	borderColor and	the window's background	color.
	       If those	are different, xterm will use the borderColor resource
	       to fill the inner border.  Otherwise, it	will use the window's
	       background color.

	       The default is "false".

       colorMode (class	ColorMode)
	       Specifies whether or not	recognition of ANSI (ISO-6429) color
	       change escape sequences should be enabled.  The default is
	       "true".

       colorRV (class ColorRV)
	       This specifies the color	to use to display reverse characters
	       if the "colorRVMode" resource is	enabled.  The default is
	       "XtDefaultForeground".

	       See also	the veryBoldColors resource which allows combining
	       reverse and color.

       colorRVMode (class ColorAttrMode)
	       Specifies whether characters with the reverse attribute should
	       be displayed in color.  Note that setting colorMode off
	       disables	all colors, including this.  The default is "false".

       colorUL (class ColorUL)
	       This specifies the color	to use to display underlined
	       characters if the "colorULMode" resource	is enabled.  The
	       default is "XtDefaultForeground".

	       See also	the veryBoldColors resource which allows combining
	       underline and color.

       colorULMode (class ColorAttrMode)
	       Specifies whether characters with the underline attribute
	       should be displayed in color or as underlined characters.  Note
	       that setting colorMode off disables all colors, including
	       underlining.  The default is "false".

       combiningChars (class CombiningChars)
	       Specifies the number of wide-characters which can be stored in
	       a cell to overstrike (combine) with the base character of the
	       cell.  This can be set to values	in the range 0 to 5.  The
	       default is "2".

       ctrlFKeys (class	CtrlFKeys)
	       In VT220	keyboard mode (see sunKeyboard resource), specifies
	       the amount by which to shift F1-F12 given a control modifier
	       (CTRL).	This allows you	to generate key	symbols	for F10-F20 on
	       a Sun/PC	keyboard.  The default is "10",	which means that CTRL
	       F1 generates the	key symbol for F11.

       curses (class Curses)
	       Specifies whether or not	the last column	bug in more(1) should
	       be worked around.  See the -cu option for details.  The default
	       is "false".

       cursorBlink (class CursorBlink)
	       Specifies whether to make the cursor blink.  Xterm accepts
	       either a	keyword	(ignoring case)	or the number shown in
	       parentheses:

	       false (0)
		  The cursor will not blink, but may be	combined with escape
		  sequences according to the cursorBlinkXOR resource.

	       true (1)
		  The cursor will blink, but may be combined with escape
		  sequences according to the cursorBlinkXOR resource.

	       always (2)
		  The cursor will always blink,	ignoring escape	sequences.
		  The menu entry will be disabled.

	       never (3)
		  The cursor will never	blink, ignoring	escape sequences.  The
		  menu entry will be disabled.

	       The default is "false".

       cursorBlinkXOR (class CursorBlinkXOR)
	       Xterm uses two inputs to	determine whether the cursor blinks:

	       o   The cursorBlink resource (which can be altered with a menu
		   entry).

	       o   Control sequences (private mode 12 and DECSCUSR).

	       The cursorBlinkXOR resource determines how those	inputs are
	       combined:

	       false
		    Xterm uses the logical-OR of the two variables.  If	either
		    is set, xterm makes	the cursor blink.

	       true
		    Xterm uses the logical-XOR of the two variables.  If only
		    one	is set,	xterm makes the	cursor blink.

	       The default is "true".

       cursorColor (class CursorColor)
	       Specifies the color to use for the text cursor.	The default is
	       "XtDefaultForeground".  By default, xterm attempts to keep this
	       color from being	the same as the	background color, since	it
	       draws the cursor	by filling the background of a text cell.  The
	       same restriction	applies	to control sequences which may change
	       this color.

	       Setting this resource overrides most of xterm's adjustments to
	       cursor color.  It will still use	reverse-video to disallow some
	       cases, such as a	black cursor on	a black	background.

       cursorOffTime (class CursorOffTime)
	       Specifies the duration of the "off" part	of the cursor blink
	       cycle-time in milliseconds.  The	same timer is used for text
	       blinking.  The default is "300".

       cursorOnTime (class CursorOnTime)
	       Specifies the duration of the "on" part of the cursor blink
	       cycle-time, in milliseconds.  The same timer is used for	text
	       blinking.  The default is "600".

       cursorUnderLine (class CursorUnderLine)
	       Specifies whether to make the cursor underlined or a box.  The
	       default is "false".

       cutNewline (class CutNewline)
	       If "false", triple clicking to select a line does not include
	       the newline at the end of the line.  If "true", the Newline is
	       selected.  The default is "true".

       cutToBeginningOfLine (class CutToBeginningOfLine)
	       If "false", triple clicking to select a line selects only from
	       the current word	forward.  If "true", the entire	line is
	       selected.  The default is "true".

       decGraphicsID (class DecGraphicsID)
	       Allows a	way to combine the graphics feature from certain DEC
	       terminals (125, 240, 241, 330, 340 or 382) with other emulation
	       levels which did	not provide the	graphics feature.  As in
	       decTerminalID, leading non-digit	characters are ignored,	e.g.,
	       "vt340" and "340" are the same.

	       If the resource value is	nonzero, xterm uses that emulation
	       level when initializing the drawing region and decoding control
	       sequences to draw graphics.

	       The default is "0".

       decTerminalID (class DecTerminalID)
	       Specifies the emulation level (100=VT100, 220=VT220, etc.),
	       used to determine the type of response to a DA control
	       sequence.  Leading non-digit characters are ignored, e.g.,
	       "vt100" and "100" are the same.	The default is "420".

       defaultString (class DefaultString)
	       Specify the character (or string) which xterm will substitute
	       when pasted text	includes a character which cannot be
	       represented in the current encoding.  For instance, pasting
	       UTF-8 text into a display of ISO-8859-1 characters will only be
	       able to display codes 0-255, while UTF-8	text can include
	       Unicode values above 255.  The default is "#" (a	single pound
	       sign).

	       If the undisplayable text would be double-width,	xterm will add
	       a space after the "#" character,	to give	roughly	the same
	       layout on the screen as the original text.

       deleteIsDEL (class DeleteIsDEL)
	       Specifies what the Delete key on	the editing keypad should send
	       when pressed.  The resource value is a string, evaluated	as a
	       boolean after startup.  Xterm uses it in	conjunction with the
	       keyboardType resource:

	       o   If the keyboard type	is "default", or "vt220" and the
		   resource is either "true" or	"maybe"	send the VT220-style
		   Remove escape sequence.  Otherwise, send DEL	(127).

	       o   If the keyboard type	is "legacy", and the resource is
		   "true" send DEL.  Otherwise,	send the Remove	sequence.

	       o   Otherwise, if the keyboard type is none of these special
		   cases, send DEL (127).

	       The default is "Maybe".	The resource is	allowed	to be a	non-
	       boolean "maybe" so that the popup menu Delete is	DEL entry does
	       not override the	keyboard type.

       directColor (class DirectColor)
	       Specifies whether to handle direct-color	control	sequences
	       using the X server's available colors, or to approximate	those
	       using a color map with 256 entries.  A "true" value enables the
	       former.	The default is "true".

       disallowedColorOps (class DisallowedColorOps)
	       Specify which features will be disabled if allowColorOps	is
	       false.  This is a comma-separated list of names.	 The default
	       value is
	       SetColor,GetColor,GetAnsiColor

	       The names are listed below.  Xterm ignores capitalization, but
	       they are	shown in mixed-case for	clarity.

	       SetColor
		    Set	a specific dynamic color.

	       GetColor
		    Report the current setting of a given dynamic color.

	       GetAnsiColor
		    Report the current setting of a given ANSI color (actually
		    any	of the colors set via ANSI-style controls).

       disallowedFontOps (class	DisallowedFontOps)
	       Specify which features will be disabled if allowFontOps is
	       false.  This is a comma-separated list of names.	 The default
	       value is

		   SetFont,GetFont

	       The names are listed below.  Xterm ignores capitalization, but
	       they are	shown in mixed-case for	clarity.

	       SetFont
		    Set	the specified font.

	       GetFont
		    Report the specified font.

       disallowedMouseOps (class DisallowedMouseOps)
	       Specify which features will be disabled if allowMouseOps	is
	       false.  This is a comma-separated list of names.	 The default
	       value is	"*" which matches all names.  The names	are listed
	       below.  Xterm ignores capitalization, but they are shown	in
	       mixed-case for clarity.

	       X10  The	original X10 mouse protocol.

	       Locator
		    DEC	locator	mode

	       VT200Click
		    X11	mouse-clicks only.

	       VT200Hilite
		    X11	mouse-clicks and highlighting.

	       AnyButton
		    XFree86 xterm any-button mode sends	button-clicks as well
		    as motion events while the button is pressed.

	       AnyEvent
		    XFree86 xterm any-event mode sends button-clicks as	well
		    as motion events whether or	not a button is	pressed.

	       FocusEvent
		    Send FocusIn/FocusOut events.

	       Extended
		    The	first extension	beyond X11 mouse protocol, this
		    encodes the	coordinates in UTF-8.  It is deprecated	in
		    favor of SGR, but provided for compatibility.

	       SGR  This is the	recommended extension for mouse-coordinates

	       URXVT
		    Like Extended, this	is provided for	compatibility.

	       AlternateScroll
		    This overrides the alternateScroll resource.

       disallowedPasteControls (class DisallowedPasteControls)
	       The allowPasteControls resource is normally used	to prevent
	       pasting C1 controls, as well as non-formatting C0 controls such
	       as the ASCII escape character.  Those characters	are simply
	       ignored.	 This resource further extends the set of control
	       characters which	cannot be pasted, converting each into a
	       space.

	       The resource value is a comma-separated list of names.  Xterm
	       ignores capitalization.	The default value is

		   BS,HT,DEL,ESC

	       The names are listed below:

	       C0   all	ASCII control characters.

	       BS   ASCII backspace

	       CR   ASCII carriage-return

	       DEL  ASCII delete

	       ESC  ASCII escape

	       FF   ASCII form-feed

	       HT   ASCII tab

	       NL   ASCII line-feed, i.e., "newline".

       disallowedTcapOps (class	DisallowedTcapOps)
	       Specify which features will be disabled if allowTcapOps is
	       false.  This is a comma-separated list of names.	 The default
	       value is

		   SetTcap,GetTcap

	       The names are listed below.  Xterm ignores capitalization, but
	       they are	shown in mixed-case for	clarity.

	       SetTcap
		    (not implemented)

	       GetTcap
		    Report specified function- and other special keys.

       disallowedWindowOps (class DisallowedWindowOps)
	       Specify which features will be disabled if allowWindowOps is
	       false.  This is a comma-separated list of names,	or (for	the
	       controls	adapted	from dtterm the	operation number).  The
	       default value is

		   20,21,SetXprop,SetSelection
		   (i.e., all except a few "dangerous" operations are allowed).

	       The names are listed below.  Xterm ignores capitalization, but
	       they are	shown in mixed-case for	clarity.  Where	a number can
	       be used as an alternative, it is	given in parentheses after the
	       name.

	       GetChecksum
		    Report checksum of characters in a rectangular region.

	       GetIconTitle (20)
		    Report xterm window's icon label as	a string.

		    Report selection data as a base64 string.

	       GetWinPosition (13)
		    Report xterm window	position as numbers.

	       GetWinSizeChars (18)
		    Report the size of the text	area in	characters as numbers.

	       GetWinSizePixels	(14)
		    Report xterm window	in pixels as numbers.

	       GetWinState (11)
		    Report xterm window	state as a number.

		    Use	full screen (i.e., resize to screen size, without
		    window decorations).

	       MinimizeWin (2)
		    Iconify window.

	       PopTitle	(23)
		    Pop	title from internal stack.

       dynamicColors (class DynamicColors)
	       Specifies whether or not	escape sequences to change colors
	       assigned	to different attributes	are recognized.

       eightBitControl (class EightBitControl)
	       Specifies whether or not	control	sequences sent by the terminal
	       should be eight-bit characters or escape	sequences.  The
	       default is "false".

       eightBitInput (class EightBitInput)
	       If "true", Meta characters (a single-byte character combined
	       with the	Meta modifier key) input from the keyboard are
	       presented as a single character,	modified according to the
	       eightBitMeta resource.  If "false", Meta	characters are
	       converted into a	two-character sequence with the	character
	       itself preceded by ESC.	The default is "true".

	       The metaSendsEscape and altSendsEscape resources	may override
	       this feature.  Generally	keyboards do not have a	key labeled
	       "Meta", but "Alt" keys are common, and they are conventionally
	       used for	"Meta".	 If they were synonymous, it would have	been
	       reasonable to name this resource	"altSendsEscape", reversing
	       its sense.  For more background on this,	see the	meta(3x)
	       function	in curses.

	       Note that the Alt key is	not necessarily	the same as the	Meta
	       modifier.  The xmodmap utility lists your key modifiers.	 X
	       defines modifiers for shift, (caps) lock	and control, as	well
	       as 5 additional modifiers which are generally used to configure
	       key modifiers.  Xterm inspects the same information to find the
	       modifier	associated with	either Meta key	(left or right), and
	       uses that key as	the Meta modifier.  It also looks for the
	       NumLock key, to recognize the modifier which is associated with
	       that.

	       If your xmodmap configuration uses the same keycodes for	Alt-
	       and Meta-keys, xterm will only see the Alt-key definitions,
	       since those are tested before Meta-keys.	 NumLock is tested
	       first.  It is important to keep these keys distinct; otherwise
	       some of xterm's functionality is	not available.

	       The eightBitInput resource is tested at startup time.  If
	       "true", the xterm tries to put the terminal into	8-bit mode.
	       If "false", on startup, xterm tries to put the terminal into
	       7-bit mode.  For	some configurations this is unsuccessful;
	       failure is ignored.  After startup, xterm does not change the
	       terminal	between	8-bit and 7-bit	mode.

	       As originally implemented in X11, the resource value did	not
	       change after startup.  However (since patch #216	in 2006) xterm
	       can modify eightBitInput	after startup via a control sequence.
	       The corresponding terminfo capabilities smm (set	meta mode) and
	       rmm (reset meta mode) have been recognized by bash for some
	       time.  Interestingly enough, bash's notion of "meta mode"
	       differs from the	standard definition (in	the terminfo manual),
	       which describes the change to the eighth	bit of a character.
	       It happens that bash views "meta	mode" as the ESC character
	       that xterm puts before a	character when a special meta key is
	       pressed.	 bash's	early documentation talks about	the ESC
	       character and ignores the eighth	bit.

       eightBitMeta (class EightBitMeta)
	       This controls the way xterm modifies the	eighth bit of a
	       single-byte key when the	eightBitInput resource is set.	The
	       default is "locale".

	       The resource value is a string, evaluated as a boolean after
	       startup.

	       false
		    The	key is sent unmodified.

	       locale
		    The	key is modified	only if	the locale uses	eight-bit
		    encoding.

	       true The	key is sent modified.

	       never
		    The	key is always sent unmodified.

	       Except for the never choice, xterm honors the terminfo
	       capabilities smm	(set meta mode)	and rmm	(reset meta mode),
	       allowing	the feature to be turned on or off dynamically.

	       If eightBitMeta is enabled when the locale uses UTF-8, xterm
	       encodes the value as UTF-8 (since patch #183 in 2003).

       eightBitOutput (class EightBitOutput)
	       Specifies whether or not	eight-bit characters sent from the
	       host should be accepted as is or	stripped when printed.	The
	       default is "true", which	means that they	are accepted as	is.

       eightBitSelectTypes (class EightBitSelectTypes)
	       Override	xterm's	default	selection target list (see
	       SELECT/PASTE) for selections in normal (ISO-8859-1) mode.  The
	       default is an empty string, i.e., "", which does	not override
	       anything.

       eraseSavedLines (class EraseSavedLines)
	       Specifies whether or not	to allow xterm extended	ED/DECSED
	       control sequences to erase the saved-line buffer.  The default
	       is "true".

       faceName	(class FaceName)
	       Specify the pattern for scalable	fonts selected from the
	       FreeType	library	if support for that library was	compiled into
	       xterm.  There is	no default value.

	       One or more fonts can be	specified, separated by	commas.	 If
	       prefixed	with "x:" or "x11:" the	specification applies to the
	       XLFD font resource.  A "xft:" prefix is accepted	but
	       unnecessary since a missing prefix for faceName means that it
	       will be used for	TrueType.  For example,

		   XTerm*faceName: x:fixed,xft:Bitstream Vera Sans Mono

	       If no faceName resource is specified, or	if there is no match
	       for both	TrueType normal	and bold fonts,	xterm uses the XLFD
	       (bitmap)	font and related resources.

	       It is possible to select	suitable bitmap	fonts using a script
	       such as this:

		   #!/bin/sh
		   FONT=`xfontsel -print`
		   test	-n "$FONT" && xfd -fn "$FONT"

	       However (even though xfd	accepts	a "-fa"	option to denote
	       FreeType	fonts),	xfontsel has not been similarly	extended.  As
	       a workaround, you may try

		   fc-list :scalable=true:spacing=mono:	family

	       to find a list of scalable fixed-pitch fonts which may be used
	       for the faceName	resource value.

       faceNameDoublesize (class FaceNameDoublesize)
	       Specify a double-width scalable font for	cases where an
	       application requires this, e.g.,	in CJK applications.  There is
	       no default value.

	       Like the	faceName resource, this	allows one or more comma-
	       separated font specifications to	be applied to the wide
	       TrueType	or XLFD	fonts.

	       If the application uses double-wide characters and this
	       resource	is not given, xterm will use a scaled version of the
	       font given by faceName.

       faceSize	(class FaceSize)
	       Specify the pointsize for fonts selected	from the FreeType
	       library if support for that library was compiled	into xterm.
	       The default is "8.0" On the VT Fonts menu, this corresponds to
	       the Default entry.

	       Although	the default is "8.0", this may not be the same as the
	       pointsize for the default bitmap	font, i.e., that assigned with
	       the -fn option, or the font resource.  The default value	of
	       faceSize	is chosen to match the size of the "fixed" font,
	       making switching	between	bitmap and TrueType fonts via the font
	       menu give comparable sizes for the window.  If your -fn option
	       uses a different	pointsize, you might want to adjust the
	       faceSize	resource to match.

	       You can specify the pointsize for TrueType fonts	selected with
	       the other size-related menu entries such	as Medium, Huge, etc.,
	       by using	one of the following resource values.  If you do not
	       specify a value,	they default to	"0.0", which causes xterm to
	       use the ratio of	font sizes from	the corresponding bitmap font
	       resources to obtain a TrueType pointsize.

	       If all of the faceSize resources	are set, then xterm will use
	       this information	to determine the next smaller/larger TrueType
	       font for	the larger-vt-font() and smaller-vt-font() actions.
	       If any are not set, xterm will use only the areas of the	bitmap
	       fonts.

       faceSize1 (class	FaceSize1)
	       Specifies the pointsize of the first alternative	font.

       faceSize2 (class	FaceSize2)
	       Specifies the pointsize of the second alternative font.

       faceSize3 (class	FaceSize3)
	       Specifies the pointsize of the third alternative	font.

       faceSize4 (class	FaceSize4)
	       Specifies the pointsize of the fourth alternative font.

       faceSize5 (class	FaceSize5)
	       Specifies the pointsize of the fifth alternative	font.

       faceSize6 (class	FaceSize6)
	       Specifies the pointsize of the sixth alternative	font.

       font (class Font)
	       Specifies the name of the normal	font.  The default is "fixed".

	       See the discussion of the locale	resource, which	describes how
	       this font may be	overridden.

	       NOTE: some resource files use patterns such as

		   *font: fixed

	       which are overly	broad, affecting both

		   xterm.vt100.font

	       and

		   xterm.vt100.utf8Fonts.font

	       which is	probably not what you intended.

       fastScroll (class FastScroll)
	       Modifies	the effect of jump scroll (jumpScroll) by suppressing
	       screen refreshes	for the	special	case when output to the	screen
	       has completely shifted the contents off-screen.	For instance,
	       cat'ing a large file to the screen does this.

       font1 (class Font1)
	       Specifies the name of the first alternative font, corresponding
	       to "Unreadable" in the standard menu.

       font2 (class Font2)
	       Specifies the name of the second	alternative font,
	       corresponding to	"Tiny" in the standard menu.

       font3 (class Font3)
	       Specifies the name of the third alternative font, corresponding
	       to "Small" in the standard menu.

       font4 (class Font4)
	       Specifies the name of the fourth	alternative font,
	       corresponding to	"Medium" in the	standard menu.

       font5 (class Font5)
	       Specifies the name of the fifth alternative font, corresponding
	       to "Large" in the standard menu.

       font6 (class Font6)
	       Specifies the name of the sixth alternative font, corresponding
	       to "Huge" in the	standard menu.

       fontDoublesize (class FontDoublesize)
	       Specifies whether xterm should attempt to use font scaling to
	       draw double-sized characters.  Some older font servers cannot
	       do this properly, will return misleading	font metrics.  The
	       default is "true".  If disabled,	xterm will simulate double-
	       sized characters	by drawing normal characters with spaces
	       between them.

       fontWarnings (class FontWarnings)
	       Specify whether xterm should report an error if it fails	to
	       load a font:

	       0    Never report an error (though the X	libraries may).

	       1    Report an error if the font	name was given as a resource
		    setting.

	       2    Always report an error on failure to load a	font.

	       The default is "1".

       forceBoxChars (class ForceBoxChars)
	       Specifies whether xterm should assume the normal	and bold fonts
	       have VT100 line-drawing characters:

	       o   The fixed-pitch ISO-8859-*-encoded fonts used by xterm
		   normally have the VT100 line-drawing	glyphs in cells	1-31.
		   Other fixed-pitch fonts may be more attractive, but lack
		   these glyphs.

	       o   When	using an ISO-10646-1 font and the wideChars resource
		   is true, xterm uses the Unicode glyphs which	match the
		   VT100 line-drawing glyphs.

	       If "false", xterm checks	for missing glyphs in the font and
	       makes line-drawing characters directly as needed.  If "true",
	       xterm assumes the font does not contain the line-drawing
	       characters, and draws them directly.  The default is "false".

	       The VT100 line-drawing character	set (also known	as the DEC
	       Special Character and Line Drawing Set) is shown	in this	table.
	       It includes a few special characters which are not used for
	       drawing lines:

	       Cell   Unicode	Description
	       ------------------------------------------------------------
	       0      U+25AE	black vertical rectangle

	       31     U+00B7	middle dot
	       ------------------------------------------------------------

       forcePackedFont (class ForcePackedFont)
	       Specifies whether xterm should use the maximum or minimum glyph
	       width when displaying using a bitmap font.  Use the maximum
	       width to	help with proportional fonts.  The default is "true",
	       denoting	the minimum width.

       forceXftHeight (class ForceXftHeight)
	       Specifies whether xterm should use the given font metrics for
	       TrueType	fonts, or amend	the ascent/descent to total no more
	       than the	given font-height.  This optional feature is used to
	       work around inconsistencies in FreeType's rounding computation.
	       The default is "false", denoting	the given metrics.

       foreground (class Foreground)
	       Specifies the color to use for displaying text in the window.
	       Setting the class name instead of the instance name is an easy
	       way to have everything that would normally appear in the	text
	       color change color.  The	default	is "XtDefaultForeground".

       formatOtherKeys (class FormatOtherKeys)
	       Overrides the format of the escape sequence used	to report
	       modified	keys with the modifyOtherKeys resource.

	       0  send modified	keys as	parameters for function-key 27
		  (default).

	       1  send modified	keys as	parameters for CSI u.

       freeBoldBox (class FreeBoldBox)
	       Specifies whether xterm should assume the bounding boxes	for
	       normal and bold fonts are compatible.  If "false", xterm
	       compares	them and will reject choices of	bold fonts that	do not
	       match the size of the normal font.  The default is "false",
	       which means that	the comparison is performed.

       geometry	(class Geometry)
	       Specifies the preferred size and	position of the	VTxxx window.
	       There is	no default for this resource.

       highlightColor (class HighlightColor)
	       Specifies the color to use for the background of	selected
	       (highlighted) text.  If not specified (i.e., matching the
	       default foreground), reverse video is used.  The	default	is
	       "XtDefaultForeground".

       highlightColorMode (class HighlightColorMode)
	       Specifies whether xterm should use highlightTextColor and
	       highlightColor to override the reversed foreground/background
	       colors in a selection.  The default is unspecified: at startup,
	       xterm checks if those resources are set to something other than
	       the default foreground and background colors.  Setting this
	       resource	disables the check.

	       The following table shows the interaction of the	highlighting
	       resources, abbreviated as shown to fit in this page:

	       HCM
		  highlightColorMode

	       HR highlightReverse

	       HBG

	       ------------------------------------------------

       highlightReverse	(class HighlightReverse)
	       Specifies whether xterm should reverse the selection foreground
	       and background colors when selecting text with reverse-video
	       attribute.  This	applies	only to	the highlightColor and
	       highlightTextColor resources, e.g., to match the	color scheme
	       of xwsh.	 If "true", xterm reverses the colors, If "false",
	       xterm does not reverse colors, The default is "true".

       highlightSelection (class HighlightSelection)
	       Tells xterm whether to highlight	all of the selected positions,
	       or only the selected text:

	       o   If "false", selecting with the mouse	highlights all
		   positions on	the screen between the beginning of the
		   selection and the current position.

	       o   If "true", xterm highlights only the	positions that contain
		   text	that can be selected.

	       The default is "false".

	       Depending on the	way your applications write to the screen,
	       there may be trailing blanks on a line.	Xterm stores data as
	       it is shown on the screen.  Erasing the display changes the
	       internal	state of each cell so it is not	considered a blank for
	       the purpose of selection.  Blanks written since the last	erase
	       are selectable.	If you do not wish to have trailing blanks in
	       a selection, use	the trimSelection resource.

       highlightTextColor (class HighlightTextColor)
	       Specifies the color to use for the foreground of	selected
	       (highlighted) text.  If not specified (i.e., matching the
	       default background), reverse video is used.  The	default	is
	       "XtDefaultBackground".

       hpLowerleftBugCompat (class HpLowerleftBugCompat)
	       Specifies whether to work around	a bug in HP's xdb, which
	       ignores termcap and always sends	ESC F to move to the lower
	       left corner.  "true" causes xterm to interpret ESC F as a
	       request to move to the lower left corner	of the screen.	The
	       default is "false".

       i18nSelections (class I18nSelections)
	       If false, xterm will not	request	the targets COMPOUND_TEXT or
	       TEXT.  The default is "true".  It may be	set to false in	order
	       to work around ICCCM violations by other	X clients.

       iconBorderColor (class BorderColor)
	       Specifies the border color for the active icon window if	this
	       feature is compiled into	xterm.	Not all	window managers	will
	       make the	icon border visible.

       iconBorderWidth (class BorderWidth)
	       Specifies the border width for the active icon window if	this
	       feature is compiled into	xterm.	The default is "2".  Not all
	       window managers will make the border visible.

       iconFont	(class IconFont)
	       Specifies the font for the miniature active icon	window,	if
	       this feature is compiled	into xterm.  The default is "nil2".

       initialFont (class InitialFont)
	       Specifies which of the VT100 fonts to use initially.  Values
	       are the same as for the set-vt-font action.  The	default	is
	       "d", i.e., "default".

       inputMethod (class InputMethod)
	       Tells xterm which type of input method to use.  There is	no
	       default method.

       internalBorder (class BorderWidth)
	       Specifies the number of pixels between the characters and the
	       window border.  The default is "2".

       italicULMode (class ColorAttrMode)
	       Specifies whether characters with the underline attribute
	       should be displayed in an italic	font or	as underlined
	       characters.  It is implemented only for TrueType	fonts.

       jumpScroll (class JumpScroll)
	       Specifies whether or not	jump scroll should be used.  This
	       corresponds to the VT102	DECSCLM	private	mode.  The default is
	       "true".	See fastScroll for a variation.

       keepClipboard (class KeepClipboard)
	       Specifies whether xterm will reuse the selection	data which it
	       copied to the clipboard rather than asking the clipboard	for
	       its current contents when told to provide the selection.	 The
	       default is "false".

	       The menu	entry Keep Clipboard allows you	to change this at
	       runtime.

       keepSelection (class KeepSelection)
	       Specifies whether xterm will keep the selection even after the
	       selected	area was touched by some output	to the terminal.  The
	       default is "true".

	       The menu	entry Keep Selection allows you	to change this at
	       runtime.

       keyboardDialect (class KeyboardDialect)
	       Specifies the initial keyboard dialect, as well as the default
	       value when the terminal is reset.  The value given is the same
	       as the final character in the control sequences which change
	       character sets.	The default is "B", which corresponds to US
	       ASCII.

       nameKeymap (class NameKeymap)
	       See the discussion of the keymap() action.

       limitFontsets (class LimitFontsets)
	       Limits the number of TrueType fallback fonts (i.e., fontset)
	       which can be used.  The default is "50".

	       This limits the number of fallback fonts	which xterm uses to
	       display characters.  Because TrueType fonts typically are
	       small, xterm may	open several fonts for good coverage, and may
	       open additional fonts to	obtain information.  You can see which
	       font-files xterm	opens by setting the environment variable
	       XFT_DEBUG to 3.	The Xft	library	and xterm write	this debugging
	       trace to	the standard output.

	       Set this	to "0" to disable fallbacks entirely.

       limitResize (class LimitResize)
	       Limits resizing of the screen via control sequence to a given
	       multiple	of the display dimensions.  The	default	is "1".

       limitResponse (class LimitResponse)
	       Limits the buffer-size used when	xterm replies to various
	       control sequences.  The default is "1024".  The minimum value
	       is "256".

       locale (class Locale)
	       Specifies how to	use luit, an encoding converter	between	UTF-8
	       and locale encodings.  The resource value (ignoring case) may
	       be:

	       true
		   Xterm will use the encoding specified by the	users'
		   LC_CTYPE locale (i.e., LC_ALL, LC_CTYPE, or LANG variables)
		   as far as possible.	This is	realized by always enabling
		   UTF-8 mode and invoking luit	in non-UTF-8 locales.

	       medium
		   Xterm will follow users' LC_CTYPE locale only for UTF-8,
		   east	Asian, and Thai	locales, where the encodings were not
		   supported by	conventional 8bit mode with changing fonts.
		   For other locales, xterm will use conventional 8bit mode.

	       checkfont
		   If mini-luit	is compiled-in,	xterm will check if a Unicode
		   font	has been specified.  If	so, it checks if the character
		   encoding for	the current locale is POSIX, Latin-1 or
		   Latin-9, uses the appropriate mapping to support those with
		   the Unicode font.  For other	encodings, xterm assumes that
		   UTF-8 encoding is required.

	       false
		   Xterm will use conventional 8bit mode or UTF-8 mode
		   according to	utf8 resource or -u8 option.

	       Any other value,	e.g., "UTF-8" or "ISO8859-2", is assumed to be
	       an encoding name; luit will be invoked to support the encoding.
	       The actual list of supported encodings depends on luit.	The
	       default is "medium".

	       Regardless of your locale and encoding, you need	an ISO-10646-1
	       font to display the result.  Your configuration may not include
	       this font, or locale-support by xterm may not be	needed.

	       At startup, xterm uses a	mechanism equivalent to	the load-vt-
	       fonts(utf8Fonts,	Utf8Fonts) action to load font name
	       subresources of the VT100 widget.  That is, resource patterns
	       such as "*vt100.utf8Fonts.font" will be loaded, and (if this
	       resource	is enabled), override the normal fonts.	 If no
	       subresources are	found, the normal fonts	such as	"*vt100.font",
	       etc., are used.

	       For instance, you could have this in your resource file:

		   *VT100.font:	12x24
		   *VT100.utf8Fonts.font:9x15

	       When started with a UTF-8 locale, xterm would use 9x15, but
	       allow you to switch to the 12x24	font using the menu entry
	       "UTF-8 Fonts".

	       The resource files distributed with xterm use ISO-10646-1
	       fonts, but do not rely on them unless you are using the locale
	       mechanism.

       localeFilter (class LocaleFilter)
	       Specifies the file name for the encoding	converter from/to
	       locale encodings	and UTF-8 which	is used	with the -lc option or
	       locale resource.	 The help message shown	by "xterm -help" lists
	       the default value, which	depends	on your	system configuration.

	       If the encoding converter requires command-line parameters, you
	       can add those after the command,	e.g.,

		   *localeFilter: xterm-filter -p

	       Alternatively, you may put those	parameter within a shell
	       script to execute the converter,	and set	this resource to point
	       to the shell script.

	       When using a locale-filter, e.g., with the -e option, or	the
	       shell, xterm first tries	passing	control	via that filter.  If
	       it fails, xterm will retry without the locale-filter.  Xterm
	       warns about the failure before retrying.

       loginShell (class LoginShell)
	       Specifies whether or not	the shell to be	run in the window
	       should be started as a login shell.  The	default	is "false".

       logFile (class Logfile)
	       Specify the name	for xterm's log	file.  If no name is
	       specified, xterm	will generate a	name when logging is enabled,
	       as described in the -l option.

       logInhibit (class LogInhibit)
	       If "true", prevent the logging feature from being enabled,
	       whether by the command-line option -l, or the menu entry	Log to
	       File.  The default is "false".

       logging (class Logging)
	       If "true", (and if logInhibit is	not set) enable	the logging
	       feature.	 This resource is set/updated by the -l	option and the
	       menu entry Log to File.	The default is "false".

       marginBell (class MarginBell)
	       Specifies whether or not	the bell should	be rung	when the user
	       types near the right margin.  The default is "false".

       maxGraphicSize (class MaxGraphicSize)
	       If xterm	is configured to support ReGIS or SIXEL	graphics, this
	       resource	controls the maximum size of a graph which can be
	       displayed.

	       The default is "1000x1000" (given as width by height).

	       If the resource is "auto" then xterm will use the decGraphicsID
	       resource	(or decTerminalID if that is not set):

	       Result	 decGraphicsID
	       ------------------------
	       768x400		   125
	       800x460		   240
	       800x460		   241
	       800x480		   330
	       800x480		   340
	       860x750		   382
	       800x480		 other

       metaSendsEscape (class MetaSendsEscape)
	       Tells xterm what	to do with input-characters modified by	Meta:

	       o   If "true", Meta characters (a character combined with the
		   Meta	modifier key) are converted into a two-character
		   sequence with the character itself preceded by ESC.	This
		   applies as well to function key control sequences, unless
		   xterm sees that Meta	is used	in your	key translations.

	       o   If "false", Meta characters input from the keyboard are
		   handled according to	the eightBitInput resource.

	       The default is "False".

       mkSamplePass (class MkSamplePass)
	       If mkSampleSize is nonzero, and mkWidth (and cjkWidth) are
	       false, on startup xterm compares	its built-in tables to the
	       system's	wide character width data to decide if it will use the
	       system's	data.  It tests	the first mkSampleSize character
	       values, and allows up to	mkSamplePass mismatches	before the
	       test fails.  The	default	(for the allowed number	of mismatches)
	       is 655 (one percent of the default value	for mkSampleSize).

       mkSampleSize (class MkSampleSize)
	       With mkSamplePass, this specifies a startup test	used for
	       initializing wide character width calculations.	The default
	       (number of characters to	check) is 65536.

       mkWidth (class MkWidth)
	       Specifies whether xterm should use a built-in version of	the
	       wide character width calculation.  See also the cjkWidth
	       resource	which can override this.  The default is "false".

	       Here is a summary of the	resources which	control	the choice of
	       wide character width calculation:

	       cjkWidth	  mkWidth   Action
	       ---------------------------------------------------------------
	       false	  false	    use	system tables subject to mkSamplePass
	       false	  true	    use	built-in tables
	       true	  false	    use	built-in CJK tables
	       true	  true	    use	built-in CJK tables

	       To disable mkWidth, and use the system's	tables,	set both
	       mkSampleSize and	mkSamplePass to	"0".  Doing that may make
	       xterm more consistent with applications running in xterm, but
	       may omit	some font glyphs whose width correctly differs from
	       the system's character tables.

       modifyCursorKeys	(class ModifyCursorKeys)
	       Tells how to handle the special case where Control-, Shift-,
	       Alt- or Meta-modifiers are used to add a	parameter to the
	       escape sequence returned	by a cursor-key.  The default is "2":

	       -1   disables the feature.

	       0    uses the old/obsolete behavior, i.e., the modifier is the
		    first parameter.

	       1    prefixes modified sequences	with CSI.

	       2    forces the modifier	to be the second parameter if it would
		    otherwise be the first.

	       3    marks the sequence with a ">" to hint that it is private.

       modifyFunctionKeys (class ModifyFunctionKeys)
	       Tells how to handle the special case where Control-, Shift-,
	       Alt- or Meta-modifiers are used to add a	parameter to the
	       escape sequence returned	by a (numbered)	function-key.  The
	       default is "2".	The resource values are	similar	to
	       modifyCursorKeys:

	       -1   permits the	user to	use shift- and control-modifiers to
		    construct function-key strings using the normal encoding
		    scheme.

	       0    uses the old/obsolete behavior, i.e., the modifier is the
		    first parameter.

	       1    prefixes modified sequences	with CSI.

	       2    forces the modifier	to be the second parameter if it would
		    otherwise be the first.

	       3    marks the sequence with a ">" to hint that it is private.

	       If modifyFunctionKeys is	zero, xterm uses Control- and Shift-
	       modifiers to allow the user to construct	numbered function-keys
	       beyond the set provided by the keyboard:

	       Control
		    adds the value given by the	ctrlFKeys resource.

	       Shift
		    adds twice the value given by the ctrlFKeys	resource.

	       Control/Shift
		    adds three times the value given by	the ctrlFKeys
		    resource.

       modifyKeyboard (class ModifyKeyboard)
	       Normally	xterm makes a special case regarding modifiers (shift,
	       control,	etc.)  to handle special keyboard layouts (legacy and
	       vt220).	This is	done to	provide	compatible keyboards for DEC
	       VT220 and related terminals that	implement user-defined keys
	       (UDK).

	       The bits	of the resource	value selectively enable modification
	       of the given category when these	keyboards are selected.	 The
	       default is "0":

	       0    The	legacy/vt220 keyboards interpret only the Control-
		    modifier when constructing numbered	function-keys.	Other
		    special keys are not modified.

	       1    allows modification	of the numeric keypad

	       2    allows modification	of the editing keypad

	       4    allows modification	of function-keys, overrides use	of
		    Shift-modifier for UDK.

	       8    allows modification	of other special keys

       modifyOtherKeys (class ModifyOtherKeys)
	       Like modifyCursorKeys, tells xterm to construct an escape
	       sequence	for ordinary (i.e., "other") keys (such	as "2")	when
	       modified	by Shift-, Control-, Alt- or Meta-modifiers.  This
	       feature does not	apply to special keys, i.e., cursor-, keypad-,
	       function- or control-keys which are labeled on your keyboard.
	       Those have key symbols which XKB	identifies uniquely.

	       For example, this feature does not apply	to special control-
	       keys (e.g., Escape, Tab,	Enter, Backspace) Other	control	keys
	       (e.g., Control-I, Control-M, Control-H) may send	escape
	       sequences when this feature is enabled.

	       The default is "0":

	       0    disables this feature.

	       1    enables this feature for keys except for those with	well-
		    known behavior, e.g., Tab, Backarrow and some special
		    control character cases which are built into the X11
		    library, e.g., Control-Space to make a NUL,	or Control-3
		    to make an Escape character.

		    Except for those special cases built into the X11 library,
		    the	Shift- and Control- modifiers are treated normally.
		    The	Alt- and Meta- modifiers do not	cause xterm to send
		    escape sequences.  Those modifier keys are interpreted
		    according to other resources, e.g.,	the metaSendsEscape
		    resource.

	       2    enables this feature for keys including the	exceptions
		    listed.  Xterm ignores the special cases built into	the
		    X11	library.  Any shifted (modified) ordinary key sends an
		    escape sequence.  The Alt- and Meta- modifiers cause xterm
		    to send escape sequences.

	       The Xterm FAQ has an extended discussion	of this	feature, with
	       examples:

	       https://invisible-island.net/xterm/modified-keys.html

       multiClickTime (class MultiClickTime)
	       Specifies the maximum time in milliseconds between multi-click
	       select events.  The default is "250" milliseconds.

       multiScroll (class MultiScroll)
	       Specifies whether or not	scrolling should be done
	       asynchronously.	The default is "false".

       nMarginBell (class Column)
	       Specifies the number of characters from the right margin	at
	       which the margin	bell should be rung, when enabled by the
	       marginBell resource.  The default is "10".

       nextEventDelay (class NextEventDelay)
	       Specifies a delay time in milliseconds before checking for new
	       X events.  The default is "1".

       numColorRegisters (class	NumColorRegisters)
	       If xterm	is configured to support ReGIS or SIXEL	graphics, this
	       specifies the number of color-registers which are available.

	       If this resource	is not specified, xterm	uses a value
	       determined by the decTerminalID resource:

	       Result	decTerminalID
	       -----------------------
		    4		  125
		    4		  240
		    4		  241
		    4		  330
		   16		  340
		    2		  382
		 1024		other

       numLock (class NumLock)
	       If "true", xterm	checks if NumLock is used as a modifier	(see
	       xmodmap(1)).  If	so, this modifier is used to simplify the
	       logic when implementing special NumLock for the sunKeyboard
	       resource.  Also (when sunKeyboard is false), similar logic is
	       used to find the	modifier associated with the left and right
	       Alt keys.  The default is "true".

       oldXtermFKeys (class OldXtermFKeys)
	       If "true", xterm	will use old-style (X11R5) escape sequences
	       for function keys F1 to F4, for compatibility with X Consortium
	       xterm.  Otherwise, it uses the VT100 codes for PF1 to PF4.  The
	       default is "false".

	       Setting this resource has the same effect as setting the
	       keyboardType to legacy.	The keyboardType resource is the
	       preferred mechanism for selecting this mode.

	       The old-style escape sequences resemble VT220 keys, but appear
	       to have been invented for xterm in X11R4.

       on2Clicks (class	On2Clicks)

       on3Clicks (class	On3Clicks)

       on4Clicks (class	On4Clicks)

       on5Clicks (class	On5Clicks)
	       Specify selection behavior in response to multiple mouse
	       clicks.	A single mouse click is	always interpreted as
	       described in the	Selection Functions section (see POINTER
	       USAGE).	Multiple mouse clicks (using the button	which
	       activates the select-start action) are interpreted according to
	       the resource values of on2Clicks, etc.  The resource value can
	       be one of these:

	       word
		  Select a "word" as determined	by the charClass resource.
		  See the CHARACTER CLASSES section.

	       line
		  Select a line	(counting wrapping).

	       group
		  Select a group of adjacent lines (counting wrapping).	 The
		  selection stops on a blank line, and does not	extend outside
		  the current page.

	       page
		  Select all visible lines, i.e., the page.

	       all
		  Select all lines, i.e., including the	saved lines.

	       regex
		  Select the best match	for the	POSIX extended regular
		  expression (ERE) which follows in the	resource value:

		  o   Xterm matches the	regular	expression against a byte
		      array for	the entire (possibly wrapped) line.  That byte
		      array may	be UTF-8 or ISO-8859-1,	depending on the mode
		      in which xterm is	running.

		  o   Xterm steps through each byte-offset in this array,
		      keeping track of the best	(longest) match.  If more than
		      one match	ties for the longest length, the first is
		      used.

		      Xterm does this to make it convenient to click anywhere
		      in the area of interest and cause	the regular expression
		      to match the entire word,	etc.

		  o   The "^" and "$" anchors in a regular expression denote
		      the ends of the entire line.

		  o   If the regular expression	contains backslashes "\" those
		      should be	escaped	"\\" because the X libraries interpret
		      backslashes in resource strings.

	       none
		  No selection action is associated with this resource.	 Xterm
		  interprets it	as the end of the list.	 For example, you may
		  use it to disable triple (and	higher)	clicking by setting
		  on3Clicks to "none".

	       The default values for on2Clicks	and on3Clicks are "word" and
	       "line", respectively.  There is no default value	for on4Clicks
	       or on5Clicks, making those inactive.  On	startup, xterm
	       determines the maximum number of	clicks by the onXClicks
	       resource	values which are set.

       openIm (class OpenIm)
	       Tells xterm whether to open the input method at startup.	 The
	       default is "true".

       pointerColor (class PointerColor)
	       Specifies the foreground	color of the pointer.  The default is
	       "XtDefaultForeground".

       pointerColorBackground (class PointerColorBackground)
	       Specifies the background	color of the pointer.  The default is
	       "XtDefaultBackground".

       pointerMode (class PointerMode)
	       Specifies when the pointer may be hidden	as the user types.  It
	       will be redisplayed if the user moves the mouse,	or clicks one
	       of its buttons.

	       0  never

	       1  the application running in xterm has not activated mouse
		  mode.	 This is the default.

	       2  always.

       pointerShape (class Cursor)
	       Specifies the name of the shape of the pointer.	The default is
	       "xterm".

       popOnBell (class	PopOnBell)
	       Specifies whether the window would be raised when Control-G is
	       received.  The default is "false".

	       If the window is	iconified, this	has no effect.	However, the
	       zIconBeep resource provides you with the	ability	to see which
	       iconified windows have sounded a	bell.

       precompose (class Precompose)
	       Tells xterm whether to precompose UTF-8 data into Normalization
	       Form C, which combines commonly-used accents onto base
	       characters.  If it does not do this, accents are	left as
	       separate	characters.  The default is "true".

       preeditType (class PreeditType)
	       Tells xterm which types of preedit (preconversion) string to
	       display.	 The default is	"OverTheSpot,Root".

       printAttributes (class PrintAttributes)
	       Specifies whether to print graphic attributes along with	the
	       text.  A	real DEC VTxxx terminal	will print the underline,
	       highlighting codes but your printer may not handle these.

	       o   "0" disables	the attributes.

	       o   "1" prints the normal set of	attributes (bold, underline,
		   inverse and blink) as VT100-style control sequences.

	       o   "2" prints ANSI color attributes as well.

	       The default is "1".

       printFileImmediate (class PrintFileImmediate)
	       When the	print-immediate	action is invoked, xterm prints	the
	       screen contents directly	to a file.  Set	this resource to the
	       prefix of the filename (a timestamp will	be appended to the
	       actual name).

	       The default is an empty string, i.e., "", However, when the
	       print-immediate action is invoked, if the string	is empty, then
	       "XTerm" is used.

       printFileOnXError (class	PrintFileOnXError)
	       If xterm	exits with an X	error, e.g., your connection is	broken
	       when the	server crashes,	it can be told to write	the contents
	       of the screen to	a file.	 To enable the feature,	set this
	       resource	to the prefix of the filename (a timestamp will	be
	       appended	to the actual name).

	       The default is an empty string, i.e., "", which disables	this
	       feature.	 However, when the print-on-error action is invoked,
	       if the string is	empty, then "XTermError" is used.

	       These error codes are handled: ERROR_XERROR, ERROR_XIOERROR and
	       ERROR_ICEERROR.

       printModeImmediate (class PrintModeImmediate)
	       When the	print-immediate	action is invoked, xterm prints	the
	       screen contents directly	to a file.  You	can use	the
	       printModeImmediate resource to tell it to use escape sequences
	       to reconstruct the video	attributes and colors.	This uses the
	       same values as the printAttributes resource.  The default is
	       "0".

       printModeOnXError (class	PrintModeOnXError)
	       Xterm implements	the printFileOnXError feature using the
	       printer feature,	although the output is written directly	to a
	       file.  You can use the printModeOnXError	resource to tell it to
	       use escape sequences to reconstruct the video attributes	and
	       colors.	This uses the same values as the printAttributes
	       resource.  The default is "0".

       printOptsImmediate (class PrintOptsImmediate)
	       Specify the range of text which is printed to a file when the
	       print-immediate action is invoked.

	       o   If zero (0),	then this selects the current (visible screen)
		   plus	the saved lines, except	if the alternate screen	is
		   being used.	In that	case, only the alternate screen	is
		   selected.

	       o   If nonzero, the bits	of this	resource value (checked	in
		   descending order) select the	range:

		   8  selects the saved	lines.

		   4  selects the alternate screen.

		   2  selects the normal screen.

		   1  selects the current screen, which	can be either the
		      normal or	alternate screen.

	       The default is "9", which selects the current visible screen
	       plus saved lines, with no special case for the alternated
	       screen.

       printOptsOnXError (class	PrintOptsOnXError)
	       Specify the range of text which is printed to a file when the
	       print-on-error action is	invoked.  The resource value is
	       interpreted the same as in printOptsImmediate.

	       The default is "9", which selects the current visible screen
	       plus saved lines, with no special case for the alternated
	       screen.

       printerAutoClose	(class PrinterAutoClose)
	       If "true", xterm	will close the printer (a pipe)	when the
	       application switches the	printer	offline	with a Media Copy
	       command.	 The default is	"false".

       printerCommand (class PrinterCommand)
	       Specifies a shell command to which xterm	will open a pipe when
	       the first MC (Media Copy) command is initiated.	The default is
	       an empty	string,	i.e., "".  If the resource value is given as
	       an empty	string,	the printer is disabled.

       printerControlMode (class PrinterControlMode)
	       Specifies the printer control mode.  A "1" selects autoprint
	       mode, which causes xterm	to print a line	from the screen	when

	       o   you move the	cursor off that	line with a line feed, form
		   feed	or vertical tab	character, or

	       o   an autowrap occurs.

	       Autoprint mode is overridden by printer controller mode (a
	       "2"), which causes all of the output to be directed to the
	       printer.	 The default is	"0".

       printerExtent (class PrinterExtent)
	       Controls	whether	a print	page function will print the entire
	       page (true), or only the	portion	within the scrolling margins
	       (false).	 The default is	"false".

       printerFormFeed (class PrinterFormFeed)
	       Controls	whether	a form feed is sent to the printer at the end
	       of a print page function.  The default is "false".

       printerNewLine (class PrinterNewLine)
	       Controls	whether	a newline is sent to the printer at the	end of
	       a print page function.  The default is "true".

       privateColorRegisters (class PrivateColorRegisters)
	       If xterm	is configured to support ReGIS or SIXEL	graphics, this
	       controls	whether	xterm allocates	separate color registers for
	       each sixel device control string, e.g., for DECGCI.  If not
	       true, color registers are allocated only	once, when the
	       terminal	is reset, and color changes  in	 any  graphic  affect
	       all graphics.  The default is "true".

       quietGrab (class	QuietGrab)
	       Controls	whether	the cursor is repainted	when NotifyGrab	and
	       NotifyUngrab event types	are received during change of focus.
	       The default is "false".

       regisDefaultFont	(class RegisDefaultFont)
	       If xterm	is configured to support ReGIS graphics, this resource
	       tells xterm which font to use if	the ReGIS data does not
	       specify one.  No	default	value is specified; xterm accepts a
	       TrueType	font specification as in the faceName resource.

	       If no value is specified, xterm draws a bitmap indicating a
	       missing character.

       regisScreenSize (class RegisScreenSize)
	       If xterm	is configured to support ReGIS graphics, this resource
	       tells xterm the default size (in	pixels)	for these graphics,
	       which also sets the default coordinate space to [0,0] (upper-
	       left) and [width,height]	(lower-right).

	       The application using ReGIS may use the "A" option of the "S"
	       command to adjust the coordinate	space or change	the
	       addressable portion of the screen.

	       Xterm accepts a special resource	value "auto", which tells
	       xterm to	use the	decGraphicsID and decTerminalID	resources to
	       set the default size based on the hardware terminal's limits.
	       Those limits are	the same as for	the maxGraphicSize resource.

	       The default is "auto".

       renderFont (class RenderFont)
	       If xterm	is built with the Xft library, this controls whether
	       the faceName resource is	used.  The default is "default".

	       The resource values are strings,	evaluated as booleans after
	       startup.

	       false
		    disable the	feature	and use	the normal (bitmap) font.

	       true
		    startup using the TrueType font specified by the faceName
		    and	faceSize resource settings.  If	there is no value for
		    faceName, disable the feature and use the normal (bitmap)
		    font.

		    After startup, you can still switch	to/from	the bitmap
		    font using the "TrueType Fonts" menu entry.

	       default
		    Enable the "TrueType Fonts"	menu entry to allow runtime
		    switching to/from TrueType fonts.  The initial font	used
		    depends upon whether the faceName resource is set:

		    o	If the faceName	resource is not	set, start by using
			the normal (bitmap) font.  Xterm has a separate
			compiled-in value for faceName for this	special	case.
			That is	normally "mono".

		    o	If the faceName	resource is set, then start by using
			the TrueType font rather than the bitmap font.

       resizeGravity (class ResizeGravity)
	       Affects the behavior when the window is resized to be taller or
	       shorter.	 NorthWest specifies that the top line of text on the
	       screen stay fixed.  If the window is made shorter, lines	are
	       dropped from the	bottom;	if the window is made taller, blank
	       lines are added at the bottom.  This is compatible with the
	       behavior	in X11R4.  SouthWest (the default) specifies that the
	       bottom line of text on the screen stay fixed.  If the window is
	       made taller, additional saved lines will	be scrolled down onto
	       the screen; if the window is made shorter, lines	will be
	       scrolled	off the	top of the screen, and the top saved lines
	       will be dropped.

       retryInputMethod	(class RetryInputMethod)
	       Tells xterm how many times to retry, in case the	input-method
	       server is not responding.  This is a different issue than
	       unsupported preedit type, etc.  You may encounter retries if
	       your X configuration (and its libraries)	are missing pieces.
	       Setting this resource to	zero "0" will cancel the retrying.
	       The default is "3".

       reverseVideo (class ReverseVideo)
	       Specifies whether or not	reverse	video should be	simulated.
	       The default is "false".

	       There are several aspects to reverse video in xterm:

	       o   The command-line -rv	option tells the X libraries to
		   reverse the foreground and background colors.  Xterm's
		   command-line	options	set resource values.  In particular,
		   the X Toolkit sets the reverseVideo resource	when the -rv
		   option is used.

	       o   If the user has also	used command-line options -fg or -bg
		   to set the foreground and background	colors,	xterm does not
		   see these options directly.	Instead, it examines the
		   resource values to reconstruct the command-line options,
		   and determine which of the colors is	the user's intended
		   foreground, etc.  Their actual values are irrelevant	to the
		   reverse video function; some	users prefer the X defaults
		   (black text on a white background), others prefer white
		   text	on a black background.

	       o   After startup, the user can toggle the "Enable Reverse
		   Video" menu entry.  This exchanges the current foreground
		   and background colors of the	VT100 widget, and repaints the
		   screen.  Because of the X resource hierarchy, the
		   reverseVideo	resource applies to more than the VT100
		   widget.

	       Programs	running	in an xterm can	also use control sequences to
	       enable the VT100	reverse	video mode.  These are independent of
	       the reverseVideo	resource and the menu entry.  Xterm exchanges
	       the current foreground and background colors when drawing text
	       affected	by these control sequences.

	       Other control sequences can alter the foreground	and background
	       colors which are	used:

	       o   Programs can	also use the ANSI color	control	sequences to
		   set the foreground and background colors.

	       o   Extensions to the ANSI color	controls (such as 16-, 88- or
		   256-colors) are treated similarly to	the ANSI control.

	       o   Using other control sequences (the "dynamic colors"
		   feature), a program can change the foreground and
		   background colors.

       reverseWrap (class ReverseWrap)
	       Specifies whether or not	reverse-wraparound should be enabled.
	       This corresponds	to xterm's private mode	45.  The default is
	       "false".

       rightScrollBar (class RightScrollBar)
	       Specifies whether or not	the scrollbar should be	displayed on
	       the right rather	than the left.	The default is "false".

       saveLines (class	SaveLines)
	       Specifies the number of lines to	save beyond the	top of the
	       screen when a scrollbar is turned on.  The default is "1024".

       scrollBar (class	ScrollBar)
	       Specifies whether or not	the scrollbar should be	displayed.
	       The default is "false".

       scrollBarBorder (class ScrollBarBorder)
	       Specifies the width of the scrollbar border.  Note that this is
	       drawn to	overlap	the border of the xterm	window.	 Modifying the
	       scrollbar's border affects only the line	between	the VT100
	       widget and the scrollbar.  The default value is 1.

       scrollKey (class	ScrollCond)
	       Specifies whether or not	pressing a key should automatically
	       cause the scrollbar to go to the	bottom of the scrolling
	       region.	This corresponds to xterm's private mode 1011.	The
	       default is "false".

       scrollLines (class ScrollLines)
	       Specifies the number of lines that the scroll-back and scroll-
	       forw actions should use as a default.  The default value	is 1.

       scrollTtyOutput (class ScrollCond)
	       Specifies whether or not	output to the terminal should
	       automatically cause the scrollbar to go to the bottom of	the
	       scrolling region.  The default is "true".

       selectToClipboard (class	SelectToClipboard)
	       Tells xterm whether to use the PRIMARY or CLIPBOARD for SELECT
	       tokens in the selection mechanism.  The set-select action can
	       change this at runtime, allowing	the user to work with programs
	       that handle only	one of these mechanisms.  The default is
	       "false",	which tells it to use PRIMARY.

       shiftFonts (class ShiftFonts)
	       Specifies whether to enable the actions larger-vt-font()	and
	       smaller-vt-font(), which	are normally bound to the shifted
	       KP_Add and KP_Subtract.	The default is "true".

       showBlinkAsBold (class ShowBlinkAsBold)
	       Tells xterm whether to display text with	blink-attribute	the
	       same as bold.  If xterm has not been configured to support
	       blinking	text, the default is "true", which corresponds to
	       older versions of xterm,	otherwise the default is "false".

       showMissingGlyphs (class	ShowMissingGlyphs)
	       Tells xterm whether to display a	box outlining places where a
	       character has been used that the	font does not represent.  The
	       default is "false".

       showWrapMarks (class ShowWrapMarks)
	       For debugging xterm and applications that may manipulate	the
	       wrapped-line flag by writing text at the	right margin, show a
	       mark on the right inner-border of the window.  The mark shows
	       which lines have	the flag set.

       signalInhibit (class SignalInhibit)
	       Specifies whether or not	the entries in the Main	Options	menu
	       for sending signals to xterm should be disallowed.  The default
	       is "false".

       sixelScrolling (class SixelScrolling)
	       If xterm	is configured to support SIXEL graphics, this resource
	       tells it	whether	to scroll up one line at a time	when sixels
	       would be	written	past the bottom	line on	the window.  The
	       default is "false".

       sixelScrollsRight (class	SixelScrollsRight)
	       If xterm	is configured to support SIXEL graphics, this resource
	       tells it	whether	to scroll to the right as needed to keep the
	       current position	visible	rather than truncate the plot on the
	       on the right.  The default is "false".

       tekGeometry (class Geometry)
	       Specifies the preferred size and	position of the	Tektronix
	       window.	There is no default for	this resource.

       tekInhibit (class TekInhibit)
	       Specifies whether or not	the escape sequence to enter Tektronix
	       mode should be ignored.	The default is "false".

       tekSmall	(class TekSmall)
	       Specifies whether or not	the Tektronix mode window should start
	       in its smallest size if no explicit geometry is given.  This is
	       useful when running xterm on displays with small	screens.  The
	       default is "false".

       tekStartup (class TekStartup)
	       Specifies whether or not	xterm should start up in Tektronix
	       mode.  The default is "false".

       tiXtraScroll (class TiXtraScroll)
	       Specifies whether xterm should scroll to	a new page when
	       processing the ti termcap entry,	i.e., the private modes	47,
	       1047 or 1049.  This is only in effect if	titeInhibit is "true",
	       because the intent of this option is to provide a picture of
	       the full-screen application's display on	the scrollback without
	       wiping out the text that	would be shown before the application
	       was initialized.	 The default for this resource is "false".

       titeInhibit (class TiteInhibit)
	       Originally specified whether or not xterm should	remove ti and
	       te termcap entries (used	to switch between alternate screens on
	       startup of many screen-oriented programs) from the TERMCAP
	       string.

	       TERMCAP is used rarely now, but xterm supports the feature on
	       modern systems:

	       o   If set, xterm also ignores the escape sequence to switch to
		   the alternate screen.

	       o   Xterm supports terminfo in a	different way, supporting
		   composite control sequences (also known as private modes)
		   1047, 1048 and 1049 which have the same effect as the
		   original 47 control sequence.

	       The default for this resource is	"false".

       titleModes (class TitleModes)
	       Tells xterm whether to accept or	return window- and icon-labels
	       in ISO-8859-1 (the default) or UTF-8.  Either can be encoded in
	       hexadecimal:

	       o   UTF-8 titles	require	special	treatment, because they	may
		   contain bytes which can be mistaken for control characters.
		   Hexadecimal-encoding	is supported to	eliminate that
		   possibility.

	       o   As an alternative, you could	use the	allowC1Printable
		   resource, which suppresses xterm's parsing of the relevant
		   control characters (and as a	result,	treats those bytes as
		   data).

	       The default for this resource is	"0".

	       Each bit	(bit "0" is 1, bit "1" is 2, etc.)  corresponds	to one
	       of the parameters set by	the title modes	control	sequence:

	       0    Set	window/icon labels using hexadecimal

	       1    Query window/icon labels using hexadecimal

	       2    Set	window/icon labels using UTF-8 (gives the same effect
		    as the utf8Title resource).

	       3    Query window/icon labels using UTF-8

       translations (class Translations)
	       Specifies the key and button bindings for menus,	selections,
	       "programmed strings", etc.  The translations resource, which
	       provides	much of	xterm's	configurability, is a feature of the X
	       Toolkit Intrinsics library (Xt).	 See the Actions section.

       trimSelection (class TrimSelection)
	       If you set highlightSelection, you can see the text which is
	       selected, including any trailing	spaces.	 Clearing the screen
	       (or a line) resets it to	a state	containing no spaces.  Some
	       lines may contain trailing spaces when an application writes
	       them to the screen.  However, you may not wish to paste lines
	       with trailing spaces.  If this resource is true,	xterm will
	       trim trailing spaces from text which is selected.  It does not
	       affect spaces which result in a wrapped line, nor will it trim
	       the trailing newline from your selection.  The default is
	       "false".

       underLine (class	UnderLine)
	       This specifies whether or not text with the underline attribute
	       should be underlined.  It may be	desirable to disable
	       underlining when	color is being used for	the underline
	       attribute.  The default is "true".

       useBorderClipping (class	UseBorderClipping)
	       Tell xterm whether to apply clipping when useClipping is	false.
	       Unlike useClipping, this	simply limits text to keep it within
	       the window borders, e.g., as a refinement to the	scaleHeight
	       workaround.  The	default	is "false".

       useClipping (class UseClipping)
	       Tell xterm whether to use clipping to keep from producing dots
	       outside the text	drawing	area.  Originally used to work around
	       for overstriking	effects, this is also needed to	work with some
	       incorrectly-sized fonts.	 The default is	"true".

       utf8 (class Utf8)
	       This specifies whether xterm will run in	UTF-8 mode.  If	you
	       set this	resource, xterm	also sets the wideChars	resource as a
	       side-effect.  The resource can be set via the menu entry	"UTF-8
	       Encoding".  The default is "default".

	       Xterm accepts either a keyword (ignoring	case) or the number
	       shown in	parentheses:

	       false (0)
		  UTF-8	mode is	initially off.	The command-line option	+u8
		  sets the resource to this value.  Escape sequences for
		  turning UTF-8	mode on/off are	allowed.

	       true (1)
		  UTF-8	mode is	initially on.  Escape sequences	for turning
		  UTF-8	mode on/off are	allowed.

	       always (2)
		  The command-line option -u8 sets the resource	to this	value.
		  Escape sequences for turning UTF-8 mode on/off are ignored.

	       default (3)
		  This is the default value of the resource.  It is changed
		  during initialization	depending on whether the locale
		  resource was set, to false (0) or always (2).	 See the
		  locale resource for additional discussion of non-UTF-8
		  locales.

	       If you want to set the value of utf8, it	should be in this
	       range.  Other nonzero values are	treated	the same as "1", i.e.,
	       UTF-8 mode is initially on, and escape sequences	for turning
	       UTF-8 mode on/off are allowed.

       utf8Fonts (class	Utf8Fonts)
	       See the discussion of the locale	resource.  This	specifies
	       whether xterm will use UTF-8 fonts specified via	resource
	       patterns	such as	"*vt100.utf8Fonts.font"	or normal (ISO-8859-1)
	       fonts via patterns such as "*vt100.font".  The resource can be
	       set via the menu	entry "UTF-8 Fonts".  The default is
	       "default".

	       Xterm accepts either a keyword (ignoring	case) or the number
	       shown in	parentheses:

	       false (0)
		      Use the ISO-8859-1 fonts.	 The menu entry	is enabled,
		      allowing the choice of fonts to be changed at runtime.

	       true (1)
		      Use the UTF-8 fonts.  The	menu entry is enabled,
		      allowing the choice of fonts to be changed at runtime.

	       always (2)
		      Always use the UTF-8 fonts.  This	also disables the menu
		      entry.

	       default (3)
		      At startup, the resource is set to true or false,
		      according	to the effective value of the utf8 resource.

       utf8Latin1 (class Utf8Latin1)
	       If true,	allow an ISO-8859-1 normal font	to be combined with an
	       ISO-10646-1 font	if the latter is given via the -fw option or
	       its corresponding resource value.  The default is "false".

       utf8SelectTypes (class Utf8SelectTypes)
	       Override	xterm's	default	selection target list (see
	       SELECT/PASTE) for selections in wide-character (UTF-8) mode.
	       The default is an empty string, i.e., "", which does not
	       override	anything.

       utf8Title (class	Utf8Title)
	       Applications can	set xterm's title by writing a control
	       sequence.  Normally this	control	sequence follows the VT220
	       convention, which encodes the string in ISO-8859-1 and allows
	       for an 8-bit string terminator.	If xterm is started in a UTF-8
	       locale, it translates the ISO-8859-1 string to UTF-8 to work
	       with the	X libraries which assume the string is UTF-8.

	       However,	some users may wish to write a title string encoded in
	       UTF-8.  The window manager is responsible for drawing window
	       titles.	Some window managers (not all) support UTF-8 encoding
	       of window titles.  Set this resource to "true" to also set
	       UTF-8 encoded title strings using the EWMH properties.

	       This feature is available as a menu entry, since	it is related
	       to the particular applications you are running within xterm.
	       You can also use	a control sequence (see	the discussion of
	       "Title Modes" in	Xterm Control Sequences), to set an equivalent
	       flag (which can also be set using the titleModes	resource).

	       Xterm accepts either a keyword (ignoring	case) or the number
	       shown in	parentheses:

	       false (0)
		      Set only ISO-8859-1 title	strings, e.g., using the ICCCM
		      WM_NAME STRING property.	The menu entry is enabled,
		      allowing the choice of title-strings to be changed at
		      runtime.

	       true (1)
		      Set both the EWMH	(UTF-8 strings)	and the	ICCCM WM_NAME,
		      etc.  The	menu entry is enabled, allowing	the choice to
		      be changed at runtime.

	       always (2)
		      Always set both the EWMH (UTF-8 strings) and the ICCCM
		      WM_NAME, etc.  This also disables	the menu entry.

	       default (3)
		      At startup, the resource is set to true or false,
		      according	to the effective value of the utf8 resource.

	       The default is "default".

       utf8Weblike (class Utf8Weblike)
	       Provide an alternate error-handling scheme for ill-formed UTF-8
	       as recommended in a W3C document.  The Unicode standard does
	       not require this	for conformance.  Some additional information
	       can be found here:

	       https://invisible-island.net/xterm/bad-utf8/

	       The default is "false".

       veryBoldColors (class VeryBoldColors)
	       Specifies whether to combine video attributes with colors
	       specified by colorBD, colorBL, colorIT, colorRV,	and colorUL.
	       The resource value is the sum of	values for each	attribute:
		 1 for reverse,
		 2 for underline,
		 4 for bold,
		 8 for blink, and
		 512 for italic

	       The default is "0".

       visualBell (class VisualBell)
	       Specifies whether or not	a visible bell (i.e., flashing)	should
	       be used instead of an audible bell when Control-G is received.
	       The default is "false", which tells xterm to use	an audible
	       bell.

       visualBellDelay (class VisualBellDelay)
	       Number of milliseconds to delay when displaying a visual	bell.
	       Default is 100.	If set to zero,	no visual bell is displayed.
	       This is useful for very slow displays, e.g., an LCD display on
	       a laptop.

       visualBellLine (class VisualBellLine)
	       Specifies whether to flash only the current line	when
	       displaying a visual bell	rather than flashing the entire
	       screen: The default is "false", which tells xterm to flash the
	       entire screen.

       vt100Graphics (class VT100Graphics)
	       This specifies whether xterm will interpret VT100 graphic
	       character escape	sequences while	in UTF-8 mode.	The default is
	       "true", to provide support for various legacy applications.

       wideBoldFont (class WideBoldFont)
	       This option specifies the font to be used for displaying	bold
	       wide text.  By default, it will attempt to use a	font twice as
	       wide as the font	that will be used to draw bold text.  If no
	       double-width font is found, it will improvise, by stretching
	       the bold	font.

       wideChars (class	WideChars)
	       Specifies if xterm should respond to control sequences that
	       process 16-bit characters.  The default is "false".

       wideFont	(class WideFont)
	       This option specifies the font to be used for displaying	wide
	       text.  By default, it will attempt to use a font	twice as wide
	       as the font that	will be	used to	draw normal text.  If no
	       double-width font is found, it will improvise, by stretching
	       the normal font.

       ximFont (class XimFont)
	       This option specifies the font to be used for displaying	the
	       preedit string in the "OverTheSpot" input method.

	       In "OverTheSpot"	preedit	type, the preedit (preconversion)
	       string is displayed at the position of the cursor.  It is the
	       XIM server's responsibility to display the preedit string.  The
	       XIM client must inform the XIM server of	the cursor position.
	       For best	results, the preedit string must be displayed with a
	       proper font.  Therefore,	xterm informs the XIM server of	the
	       proper font.  The font is be supplied by	a "fontset", whose
	       default value is	"*".  This matches every font, the X library
	       automatically chooses fonts with	proper charsets.  The ximFont
	       resource	is provided to override	this default font setting.

   Tek4014 Widget Resources
       The following resources are specified as	part of	the tek4014 widget
       (class Tek4014).	 These are specified by	patterns such as
       "XTerm.tek4014.NAME":

	       Specifies the large font	to use in the Tektronix	window.

       fontSmall (class	Font)
	       Specifies the small font	to use in the Tektronix	window.

       ginTerminator (class GinTerminator)
	       Specifies what character(s) should follow a GIN report or
	       status report.  The possibilities are "none", which sends no
	       terminating characters, "CRonly", which sends CR, and "CR&EOT",
	       which sends both	CR and EOT.  The default is "none".

       height (class Height)
	       Specifies the height of the Tektronix window in pixels.

       initialFont (class InitialFont)
	       Specifies which of the four Tektronix fonts to use initially.
	       Values are the same as for the set-tek-text action.  The
	       default is "large".

       width (class Width)
	       Specifies the width of the Tektronix window in pixels.

   Menu	Resources

   Scrollbar Resources
       The following resources are useful when specified for the Athena
       Scrollbar widget:

       thickness (class	Thickness)
	       Specifies the width in pixels of	the scrollbar.

       background (class Background)
	       Specifies the color to use for the background of	the scrollbar.

       foreground (class Foreground)
	       Specifies the color to use for the foreground of	the scrollbar.
	       The "thumb" of the scrollbar is a simple	checkerboard pattern
	       alternating pixels for foreground and background	color.

POINTER	USAGE
       Once the	VTxxx window is	created, xterm allows you to select text and
       copy it within the same or other	windows	using the pointer or the
       keyboard.

       A "pointer" could be a mouse, touchpad or similar device.  X
       applications generally do not care, since they see only button events
       which have

       o   position and

       o   button up/down state

       Xterm can see these events as long as it	has focus.

       The keyboard also supplies events, but it is less flexible than the
       pointer for selecting/copying text.

       Events are applied to actions using the translations resource.  See
       Actions for a complete list, and	Default	Key Bindings for the built-in
       set of translations resources.

   Selection Functions
       The selection functions are invoked when	the pointer buttons are	used
       with no modifiers, and when they	are used with the "shift" key.	The
       assignment of the functions described below to keys and buttons may be
       changed through the resource database; see Actions below.

       Pointer button one (usually left)
	    is used to save text into the cut buffer:

		~Meta <Btn1Down>:select-start()

	    Move the cursor to beginning of the	text, and then hold the	button
	    down while moving the cursor to the	end of the region and
	    releasing the button.  The selected	text is	highlighted and	is
	    saved in the global	cut buffer and made the	selection when the
	    button is released:

		<BtnUp>:select-end(SELECT, CUT_BUFFER0)	\n

	    Normally (but see the discussion of	on2Clicks, etc):

	    o	Double-clicking	selects	by words.

	    o	Triple-clicking	selects	by lines.

	    o	Quadruple-clicking goes	back to	characters, etc.

	    Multiple-click is determined by the	time from button up to button
	    down, so you can change the	selection unit in the middle of	a
	    selection.	Logical	words and lines	selected by double- or triple-
	    clicking may wrap across more than one screen line if lines	were
	    wrapped by xterm itself rather than	by the application running in
	    the	window.	 If the	key/button bindings specify that an X
	    selection is to be made, xterm will	leave the selected text
	    highlighted	for as long as it is the selection owner.

       Pointer button two (usually middle)
	    "types" (pastes) the text from the given selection,	if any,
	    otherwise from the cut buffer, inserting it	as keyboard input:

		~Ctrl ~Meta <Btn2Up>:insert-selection(SELECT, CUT_BUFFER0)

       Pointer button three (usually right)
	    extends the	current	selection.

		~Ctrl ~Meta <Btn3Down>:start-extend()

	    (Without loss of generality, you can swap "right" and "left"
	    everywhere in the rest of this paragraph.)	If pressed while
	    closer to the right	edge of	the selection than the left, it
	    extends/contracts the right	edge of	the selection.	If you
	    contract the selection past	the left edge of the selection,	xterm
	    assumes you	really meant the left edge, restores the original
	    selection, then extends/contracts the left edge of the selection.
	    Extension starts in	the selection unit mode	that the last
	    selection or extension was performed in; you can multiple-click to
	    cycle through them.

       By cutting and pasting pieces of	text without trailing new lines, you
       can take	text from several places in different windows and form a
       command to the shell, for example, or take output from a	program	and
       insert it into your favorite editor.  Since cut buffers are globally
       shared among different applications, you	may regard each	as a "file"
       whose contents you know.	 The terminal emulator and other text programs
       should be treating it as	if it were a text file,	i.e., the text is
       delimited by new	lines.

   Scrolling
       The scroll region displays the position and amount of text currently
       showing in the window (highlighted) relative to the amount of text
       actually	saved.	As more	text is	saved (up to the maximum), the size of
       the highlighted area decreases.

       Clicking	button one with	the pointer in the scroll region moves the
       adjacent	line to	the top	of the display window.

       Clicking	button three moves the top line	of the display window down to
       the pointer position.

       Clicking	button two moves the display to	a position in the saved	text
       that corresponds	to the pointer's position in the scrollbar.

   Tektronix Pointer
       Unlike the VTxxx	window,	the Tektronix window does not allow the
       copying of text.	 It does allow Tektronix GIN mode, and in this mode
       the cursor will change from an arrow to a cross.	 Pressing any key will
       send that key and the current coordinate	of the cross cursor.  Pressing
       button one, two,	or three will return the letters "l", "m", and "r",
       respectively.  If the "shift" key is pressed when a pointer button is
       pressed,	the corresponding upper	case letter is sent.  To distinguish a
       pointer button from a key, the high bit of the character	is set (but
       this is bit is normally stripped	unless the terminal mode is RAW; see
       tty(4) for details).

SELECT/PASTE
       X clients provide select	and paste support by responding	to requests
       conveyed	by the X server.  The X	server holds data in "atoms" which
       correspond to the different types of selection (PRIMARY,	SECONDARY,
       CLIPBOARD) as well as the similar cut buffer mechanism (CUT_BUFFER0 to
       CUT_BUFFER7).  Those are	documented in the ICCCM.

       The ICCCM deals with the	underlying mechanism for select/paste.	It
       does not	mention	highlighting.  The selection is	not the	same as
       highlighting.  Xterm (like many applications) uses highlighting to show
       you the currently selected text.	 An X application may own a selection,
       which allows it to be the source	of data	copied using a given selection
       atom Xterm may continue owning a	selection after	it stops highlighting
       (see keepSelection).

   PRIMARY
       When configured to use the primary selection (the default), xterm can
       provide the selection data in ways which	help to	retain character
       encoding	information as it is pasted.

       The PRIMARY token is a standard X feature, documented in	the ICCCM
       (Inter-Client Communication Conventions Manual),	which states

	  The selection	named by the atom PRIMARY is used for all commands
	  that take only a single argument and is the principal	means of
	  communication	between	clients	that use the selection mechanism.

       A user "selects"	text on	xterm, which highlights	the selected text.  A
       subsequent "paste" to another client forwards a request to the client
       owning the selection.  If xterm owns the	primary	selection, it makes
       the data	available in the form of one or	more "selection	targets".  If
       it does not own the primary selection, e.g., if it has released it or
       another client has asserted ownership, it relies	on cut-buffers to pass
       the data.  But cut-buffers handle only ISO-8859-1 data (officially -
       some clients ignore the rules).

   CLIPBOARD
       When configured to use the clipboard (using the selectToClipboard
       resource), the problem with persistence of ownership is bypassed.
       Otherwise, there	is no difference regarding the data which can be
       passed via selection.

       The selectToClipboard resource is a compromise, allowing	CLIPBOARD to
       be treated almost like PRIMARY, unlike the ICCCM, which describes
       CLIPBOARD in different terms than PRIMARY or SECONDARY.	Its lengthy
       explanation begins with the essential points:

	  The selection	named by the atom CLIPBOARD is used to hold data that
	  is being transferred between clients,	that is, data that usually is
	  being	cut and	then pasted or copied and then pasted.	Whenever a
	  client wants to transfer data	to the clipboard:

	  o   It should	assert ownership of the	CLIPBOARD.

	  o   If it succeeds in	acquiring ownership, it	should be prepared to
	      respond to a request for the contents of the CLIPBOARD in	the
	      usual way	(retaining the data to be able to return it).  The
	      request may be generated by the clipboard	client described
	      below.

   SELECT
       However,	many applications use CLIPBOARD	in imitation of	other
       windowing systems.  The selectToClipboard resource (and corresponding
       menu entry Select to Clipboard) introduce the SELECT token (known only
       to xterm) which chooses between the PRIMARY and CLIPBOARD tokens.

       Without using this feature, one can use workarounds such	as the xclip
       program to show the contents of the X clipboard within an xterm window.

   SECONDARY
       This is used less often than PRIMARY or CLIPBOARD.  According to	the
       ICCCM, it is used

       o   As the second argument to commands taking two arguments (for
	   example, "exchange primary and secondary selections")

       o   As a	means of obtaining data	when there is a	primary	selection and
	   the user does not want to disturb it

   Selection Targets
       The different types of data which are passed depend on what the
       receiving client	asks for.  These are termed selection targets.

       When asking for the selection data, xterm tries the following types in
       this order:

	    UTF8_STRING
		 This is an XFree86 extension, which denotes that the data is
		 encoded in UTF-8.  When xterm is built	with wide-character
		 support, it both accepts and provides this type.

	    TEXT the text is in	the encoding which corresponds to your current
		 locale.

	    COMPOUND_TEXT
		 this is a format for multiple character set data, such	as
		 multi-lingual text.  It can store UTF-8 data as a special
		 case.

	    STRING
		 This is Latin 1 (ISO-8859-1) data.

       The middle two (TEXT and	COMPOUND_TEXT) are added if xterm is
       configured with the i18nSelections resource set to "true".

       UTF8_STRING is preferred	(therefore first in the	list) since xterm
       stores text as Unicode data when	running	in wide-character mode,	and no
       translation is needed.  On the other hand, TEXT and COMPOUND_TEXT may
       require translation.  If	the translation	is incomplete, they will
       insert X's "defaultString" whose	value cannot be	set, and may simply be
       empty.  Xterm's defaultString resource specifies	the string to use for
       incomplete translations of the UTF8_STRING.

       You can alter the types which xterm tries using the eightBitSelectTypes
       or utf8SelectTypes resources.  For instance, you	might have some
       specific	locale setting which does not use UTF-8	encoding.  The
       resource	value is a comma-separated list	of the selection targets,
       which consist of	the names shown.  You can use the special name I18N to
       denote the optional inclusion of	TEXT and COMPOUND_TEXT.	 The names are
       matched ignoring	case, and can be abbreviated.  The default list	can be
       expressed in several ways, e.g.,

	      UTF8_STRING,I18N,STRING
	      utf8,i18n,string
	      u,i,s

   Mouse Protocol
       Applications can	send escape sequences to xterm to cause	it to send
       escape sequences	back to	the computer when you press a pointer button,
       or even (depending on which escape sequence) send escape	sequences back
       to the computer as you move the pointer.

       These escape sequences and the responses, called	the mouse protocol,
       are documented in XTerm Control Sequences.  They	do not appear in the
       actions invoked by the translations resource because the	resource does
       not change while	you run	xterm, whereas applications can	change the
       mouse prototol (i.e., enable, disable, use different modes).

       However,	the mouse protocol is interpreted within the actions that are
       usually associated with the pointer buttons.  Xterm ignores the mouse
       protocol	in the insert-selection	action if the shift-key	is pressed at
       the same	time.  It also modifies	a few other actions if the shift-key
       is pressed, e.g., suppressing the response with the pointer position,
       though not eliminating changes to the selected text.

MENUS
       Xterm has four menus, named mainMenu, vtMenu, fontMenu, and tekMenu.
       Each menu pops up under the correct combinations	of key and button
       presses.	 Each menu is divided into sections, separated by a horizontal
       line.  Some menu	entries	correspond to modes that can be	altered.  A
       check mark appears next to a mode that is currently active.  Selecting
       one of these modes toggles its state.  Other menu entries are commands;
       selecting one of	these performs the indicated function.

       All of the menu entries correspond to X actions.	 In the	list below,
       the menu	label is shown followed	by the action's	name in	parenthesis.

   Main	Options
       The xterm mainMenu pops up when the "control" key and pointer button
       one are pressed in a window.  This menu contains	items that apply to
       both the	VTxxx and Tektronix windows.  There are	several	sections:

       Commands	for managing X events:

	      Toolbar (resource	toolbar)
		     Clicking on the "Toolbar" menu entry hides	the toolbar if
		     it	is visible, and	shows it if it is not.

	      Secure Keyboard (resource	securekbd)
		     The Secure	Keyboard mode is helpful when typing in
		     passwords or other	sensitive data in an unsecure
		     environment (see SECURITY below, but read the limitations
		     carefully).

	      Allow SendEvents (resource allowsends)
		     Specifies whether or not synthetic	key and	button events
		     generated using the X protocol SendEvent request should
		     be	interpreted or discarded.  This	corresponds to the
		     allowSendEvents resource.

	      Redraw Window (resource redraw)
		     Forces the	X display to repaint; useful in	some
		     environments.

       Commands	for capturing output:

	      Log to File (resource logging)
		     Captures text sent	to the screen in a log file, as	in the
		     -l	logging	option.

	      Print-All	Immediately (resource print-immediate)
		     Invokes the print-immediate action, sending the text of
		     the current window	directly to a file, as specified by
		     the printFileImmediate, printModeImmediate	and
		     printOptsImmediate	resources.

	      Print-All	on Error (resource print-on-error)
		     Invokes the print-on-error	action,	which toggles a	flag
		     telling xterm that	if it exits with an X error, to	send
		     the text of the current window directly to	a file,	as
		     specified by the printFileOnXError, printModeOnXError and
		     printOptsOnXError resources.

	      Print Window (resource print)
		     Sends the text of the current window to the program given
		     in	the printerCommand resource.

	      Redirect to Printer (resource print-redir)
		     This sets the printerControlMode to 0 or 2.  You can use
		     this to turn the printer on as if an application had sent
		     the appropriate control sequence.	It is also useful for
		     switching the printer off if an application turns it on
		     without resetting the print control mode.

	      XHTML Screen Dump	(resource dump-html)
		     Available only when compiled with screen dump support.
		     Invokes the dump-html action.  This creates an XHTML file
		     matching the contents of the current screen, including
		     the border, internal border, colors and most attributes:
		     bold, italic, underline, faint, strikeout,	reverse; blink
		     is	rendered as white-on-red; double underline is rendered
		     the same as underline since there is no portable
		     equivalent	in CSS 2.2.

		     The font is whatever your browser uses for	preformatted
		     (<pre>) elements.	The XHTML file references a cascading
		     style sheet (CSS) named "xterm.css" that you can create
		     to	select a font or override properties.

		     The following CSS selectors are used with the expected
		     default behavior in the XHTML file:

		     .ul for underline,
		     .bd for bold,
		     .it for italic,
		     .st for strikeout,
		     .lu for strikeout combined	with underline.

		     In	addition you may use

		     .ev to affect even	numbered lines and
		     .od to affect odd numbered	lines.

		     Attributes	faint, reverse and blink are implemented as
		     style attributes setting color properties.	 All colors
		     are specified as RGB percentages in order to support
		     displays with 10 bits per RGB.

		     The name of the file will be

			 xterm.yyyy.MM.dd.hh.mm.ss.xhtml

		     where yyyy, MM, dd, hh, mm	and ss are the year, month,
		     day, hour,	minute and second when the screen dump was
		     performed (the file is created in the directory xterm is
		     started in, or the	home directory for a login xterm).

		     The dump-html action can also be triggered	using the
		     Media Copy	control	sequence CSI 1 0 i, for	example	from a
		     shell script with

			 printf	'\033[10i'

		     Only the UTF-8 encoding is	supported.

	      SVG Screen Dump (resource	dump-svg)
		     Available only when compiled with screen dump support.
		     Invokes the dump-svg action.  This	creates	a Scalable
		     Vector Graphics (SVG) file	matching the contents of the
		     current screen, including the border, internal border,
		     colors and	most attributes: bold, italic, underline,
		     double underline, faint, strikeout, reverse; blink	is
		     rendered as white-on-red.	The font is whatever your
		     renderer uses for the monospace font-family.  All colors
		     are specified as RGB percentages in order to support
		     displays with 10 bits per RGB.

		     The name of the file will be

			 xterm.yyyy.MM.dd.hh.mm.ss.svg

		     where yyyy, MM, dd, hh, mm	and ss are the year, month,
		     day, hour,	minute and second when the screen dump was
		     performed (the file is created in the directory xterm is
		     started in, or the	home directory for a login xterm).

		     The dump-svg action can also be triggered using the Media
		     Copy control sequence CSI 1 1 i, for example from a shell
		     script with

			 printf	'\033[11i'

		     Only the UTF-8 encoding is	supported.

       Modes for setting keyboard style:

	      8-Bit Controls (resource 8-bit-control)
		     Enabled for VT220 emulation, this controls	whether	xterm
		     will send 8-bit control sequences rather than using 7-bit
		     (ASCII) controls, e.g., sending a byte in the range
		     128-159 rather than the escape character followed by a
		     second byte.  Xterm always	interprets both	8-bit and
		     7-bit control sequences (see Xterm	Control	Sequences).
		     This corresponds to the eightBitControl resource.

	      Backarrow	Key (BS/DEL) (resource backarrow key)
		     Modifies the behavior of the backarrow key, making	it
		     transmit either a backspace (8) or	delete (127)
		     character.	 This corresponds to the backarrowKey
		     resource.

	      Alt/NumLock Modifiers (resource num-lock)
		     Controls the treatment of Alt- and	NumLock-key modifiers.
		     This corresponds to the numLock resource.

	      Meta Sends Escape	(resource meta-esc)
		     Controls whether Meta keys	are converted into a two-
		     character sequence	with the character itself preceded by
		     ESC.  This	corresponds to the metaSendsEscape resource.

	      Delete is	DEL (resource delete-is-del)
		     Controls whether the Delete key on	the editing keypad
		     should send DEL (127) or the VT220-style Remove escape
		     sequence.	This corresponds to the	deleteIsDEL resource.

	      Old Function-Keys	(resource oldFunctionKeys)

	      HP Function-Keys (resource hpFunctionKeys)

	      SCO Function-Keys	(resource scoFunctionKeys)

	      Sun Function-Keys	(resource sunFunctionKeys)

	      VT220 Keyboard (resource sunKeyboard)
		     These act as a radio-button, selecting one	style for the
		     keyboard layout.  The layout corresponds to more than one
		     resource setting: sunKeyboard, sunFunctionKeys,
		     scoFunctionKeys and hpFunctionKeys.

       Commands	for process signalling:

	      Send STOP	Signal (resource suspend)

	      Send CONT	Signal (resource continue)

	      Send INT Signal (resource	interrupt)

	      Send HUP Signal (resource	hangup)

	      Send TERM	Signal (resource terminate)

	      Send KILL	Signal (resource kill)
		     These send	the SIGTSTP, SIGCONT, SIGINT, SIGHUP, SIGTERM
		     and SIGKILL signals respectively, to the process group of
		     the process running under xterm (usually the shell).  The
		     SIGCONT function is especially useful if the user has
		     accidentally typed	CTRL-Z,	suspending the process.

	      Quit (resource quit)
		     Stop processing X events except to	support	the -hold
		     option, and then send a SIGHUP signal to the process
		     group of the process running under	xterm (usually the
		     shell).

   VT Options
       The xterm vtMenu	sets various modes in the VTxxx	emulation, and is
       popped up when the "control" key	and pointer button two are pressed in
       the VTxxx window.

       VTxxx Modes:

	      Enable Scrollbar (resource scrollbar)
		     Enable (or	disable) the scrollbar.	 This corresponds to
		     the -sb option and	the scrollBar resource.

	      Enable Jump Scroll (resource jumpscroll)
		     Enable (or	disable) jump scrolling.  This corresponds to
		     the -j option and the jumpScroll resource.

	      Enable Reverse Video (resource reversevideo)
		     Enable (or	disable) reverse-video.	 This corresponds to
		     the -rv option and	the reverseVideo resource.

	      Enable Auto Wraparound (resource autowrap)
		     Enable (or	disable) auto-wraparound.  This	corresponds to
		     the -aw option and	the autoWrap resource.

	      Enable Reverse Wraparound	(resource reversewrap)
		     Enable (or	disable) reverse wraparound.  This corresponds
		     to	the -rw	option and the reverseWrap resource.

	      Enable Auto Linefeed (resource autolinefeed)
		     Enable (or	disable) auto-linefeed.	 This is the VT102 NEL
		     function, which causes the	emulator to emit a line	feed
		     after each	carriage return.  There	is no corresponding
		     command-line option or resource setting.

	      Enable Application Cursor	Keys (resource appcursor)
		     Enable (or	disable) application cursor keys.  This
		     corresponds to the	appcursorDefault resource.  There is
		     no	corresponding command-line option.

	      Enable Application Keypad	(resource appkeypad)
		     Enable (or	disable) application keypad keys.  This
		     corresponds to the	appkeypadDefault resource.  There is
		     no	corresponding command-line option.

	      Scroll to	Bottom on Key Press (resource scrollkey)
		     Enable (or	disable) scrolling to the bottom of the
		     scrolling region on a keypress.  This corresponds to the
		     -sk option	and the	scrollKey resource.

		     As	a special case,	the XON	/ XOFF keys (control/S and
		     control/Q)	are ignored.

	      Scroll to	Bottom on Tty Output (resource scrollttyoutput)
		     Enable (or	disable) scrolling to the bottom of the
		     scrolling region on output	to the terminal.  This
		     corresponds to the	-si option and the scrollTtyOutput
		     resource.

	      Allow 80/132 Column Switching (resource allow132)
		     Enable (or	disable) switching between 80 and 132 columns.
		     This corresponds to the -132 option and the c132
		     resource.

	      Keep Selection (resource keepSelection)
		     Tell xterm	whether	to disown the selection	when it	stops
		     highlighting it, e.g., when an application	modifies the
		     display so	that it	no longer matches the text which has
		     been highlighted.	As long	as xterm continues to own the
		     selection for a given atom, it can	provide	the
		     corresponding text	to other clients which request the
		     selection using that atom.

		     This corresponds to the keepSelection resource.  There is
		     no	corresponding command-line option.

		     Telling xterm to not disown the selection does not
		     prevent other applications	from taking ownership of the
		     selection.	 When that happens, xterm receives
		     notification that this has	happened, and removes its
		     highlighting.

		     See SELECT/PASTE for more information.

	      Select to	Clipboard (resource selectToClipboard)
		     Tell xterm	whether	to use the PRIMARY or CLIPBOARD	for
		     SELECT tokens in the translations resource	which maps
		     keyboard and mouse	actions	to select/paste	actions.

		     This corresponds to the selectToClipboard resource.
		     There is no corresponding command-line option.

		     The keepSelection resource	setting	applies	to CLIPBOARD
		     selections	just as	it does	for PRIMARY selections.
		     However some window managers treat	the clipboard
		     specially.	 For instance, XQuartz's synchronization
		     between the OSX pasteboard	and the	X11 clipboard causes
		     applications to lose the selection	ownership for that
		     atom when a selection is copied to	the clipboard.

		     See SELECT/PASTE for more information.

	      Enable Visual Bell (resource visualbell)
		     Enable (or	disable) visible bell (i.e., flashing) instead
		     of	an audible bell.  This corresponds to the -vb option
		     and the visualBell	resource.

	      Enable Bell Urgency (resource bellIsUrgent)
		     Enable (or	disable) Urgency window	manager	hint when
		     Control-G is received.  This corresponds to the
		     bellIsUrgent resource.

	      Enable Pop on Bell (resource poponbell)
		     Enable (or	disable) raising of the	window when Control-G
		     is	received.  This	corresponds to the -pop	option and the
		     popOnBell resource.

	      Enable Blinking Cursor (resource cursorblink)
		     Enable (or	disable) the blinking-cursor feature.  This
		     corresponds to the	-bc option and the cursorBlink
		     resource.	There are also escape sequences	(see Xterm
		     Control Sequences):

		     o	 If the	cursorBlinkXOR resource	is set,	the menu entry
			 and the escape	sequence states	will be	XOR'd: if both
			 are enabled, the cursor will not blink, if only one
			 is enabled, the cursor	will blink.

		     o	 If the	cursorBlinkXOR is not set; if either the menu
			 entry or the escape sequence states are set, the
			 cursor	will blink.

		     In	either case, the checkbox for the menu shows the state
		     of	the cursorBlink	resource, which	may not	correspond to
		     what the cursor is	actually doing.

	      Enable Alternate Screen Switching	(resource titeInhibit)
		     Enable (or	disable) switching between the normal and
		     alternate screens.	 This corresponds to the titeInhibit
		     resource.	There is no corresponding command-line option.

	      Enable Active Icon (resource activeicon)
		     Enable (or	disable) the active-icon feature.  This
		     corresponds to the	-ai option and the activeIcon
		     resource.

	      Sixel Scrolling (resource	sixelScrolling)
		     When enabled, sixel graphics are positioned at the
		     current text cursor location, scroll the image vertically
		     if	larger than the	screen,	and leave the text cursor at
		     the start of the next complete line after the image when
		     returning to text mode (this is the default).  When
		     disabled, sixel graphics are positioned at	the upper left
		     of	the screen, are	cropped	to fit the screen, and do not
		     affect the	text cursor location.  This corresponds	to the
		     sixelScrolling resource.  There is	no corresponding
		     command-line option.

	      Private Color Registers (resource	privateColorRegisters)
		     If	xterm is configured to support ReGIS graphics, this
		     controls whether a	private	color palette can be used.

		     When enabled, each	graphic	image uses a separate set of
		     color registers, so that it essentially has a private
		     palette (this is the default).  If	it is not set, all
		     graphics images share a common set	of registers which is
		     how sixel and ReGIS graphics worked on actual hardware.
		     The default is likely a more useful mode on modern
		     TrueColor hardware.

		     This corresponds to the privateColorRegisters resource.
		     There is no corresponding command-line option.

       VTxxx Commands:

	      Do Soft Reset (resource softreset)
		     Reset scroll regions.  This can be	convenient when	some
		     program has left the scroll regions set incorrectly
		     (often a problem when using VMS or	TOPS-20).  This
		     corresponds to the	VT220 DECSTR control sequence.

	      Do Full Reset (resource hardreset)
		     The full reset entry will clear the screen, reset tabs to
		     every eight columns, and reset the	terminal modes (such
		     as	wrap and smooth	scroll)	to their initial states	just
		     after xterm has finished processing the command line
		     options.  This corresponds	to the VT102 RIS control
		     sequence, with a few obvious differences.	For example,
		     your session is not disconnected as a real	VT102 would
		     do.

	      Reset and	Clear Saved Lines (resource clearsavedlines)
		     Perform a full reset, and also clear the saved lines.

       Commands	for setting the	current	screen:

	      Show Tek Window (resource	tekshow)
		     When enabled, pops	the Tektronix 4014 window up (makes it
		     visible).	When disabled, hides the Tektronix 4014
		     window.

	      Switch to	Tek Mode (resource tekmode)
		     When enabled, pops	the Tektronix 4014 window up if	it is
		     not already visible, and switches the input stream	to
		     that window.  When	disabled, hides	the Tektronix 4014
		     window and	switches input back to the VTxxx window.

	      Hide VT Window (resource vthide)
		     When enabled, hides the VTxxx window, shows the Tektronix
		     4014 window if it was not already visible and switches
		     the input stream to that window.  When disabled, shows
		     the VTxxx window, and switches the	input stream to	that
		     window.

	      Show Alternate Screen (resource altscreen)
		     When enabled, shows the alternate screen.	When disabled,
		     shows the normal screen.  Note that the normal screen may
		     have saved	lines; the alternate screen does not.

   VT Fonts
       The xterm fontMenu pops up when the "control" key and pointer button
       three are pressed in a window.  It sets the font	used in	the VTxxx
       window, or modifies the way the font is specified or displayed.	There
       are several sections.

       The first section allows	you to select the font from a set of
       alternatives:

	      Default (resource	fontdefault)
		     Set the font to the default, i.e.,	that given by the
		     *VT100.font resource.

	      Unreadable (resource font1)
		     Set the font to that given	by the *VT100.font1 resource.

	      Tiny (resource font2)
		     Set the font to that given	by the *VT100.font2 resource.

	      Small (resource font3)
		     Set the font to that given	by the *VT100.font3 resource.

	      Medium (resource font4)
		     Set the font to that given	by the *VT100.font4 resource.

	      Large (resource font5)
		     Set the font to that given	by the *VT100.font5 resource.

	      Huge (resource font6)
		     Set the font to that given	by the *VT100.font6 resource.

	      Escape Sequence (resource	fontescape)
		     This allows you to	set the	font last specified by the Set
		     Font escape sequence (see Xterm Control Sequences).

	      Selection	(resource fontsel)
		     This allows you to	set the	font specified the current
		     selection as a font name (if the PRIMARY selection	is
		     owned).

       The second section allows you to	modify the way it is displayed:

	      Bold Fonts (resource allow-bold-fonts)
		     This is normally checked (enabled).  When unchecked,
		     xterm will	not use	bold fonts.  The setting corresponds
		     to	the allowBoldFonts resource.

	      Line-Drawing Characters (resource	font-linedrawing)
		     When set, tells xterm to draw its own line-drawing
		     characters.  Otherwise it relies on the font containing
		     these.  Compare to	the forceBoxChars resource.

	      Packed Font (resource font-packed)
		     When set, tells xterm to use the minimum glyph-width from
		     a font when displaying characters.	 Use the maximum width
		     (unchecked) to help display proportional fonts.  Compare
		     to	the forcePackedFont resource.

	      Doublesized Characters (resource font-doublesize)
		     When set, xterm may ask the font server to	produce	scaled
		     versions of the normal font, for VT102 double-size
		     characters.

       The third section allows	you to modify the way it is specified:

	      TrueType Fonts (resource render-font)
		     If	the renderFont and corresponding resources were	set,
		     this is a further control whether xterm will actually use
		     the Xft library calls to obtain a font.

	      UTF-8 Encoding (resource utf8-mode)
		     This controls whether xterm uses UTF-8 encoding of
		     input/output.  It is useful for temporarily switching
		     xterm to display text from	an application which does not
		     follow the	locale settings.  It corresponds to the	utf8
		     resource.

	      UTF-8 Fonts (resource utf8-fonts)
		     This controls whether xterm uses UTF-8 fonts for display.
		     It	is useful for temporarily switching xterm to display
		     text from an application which does not follow the	locale
		     settings.	It combines the	utf8 and utf8Fonts resources,
		     subject to	the locale resource.

	      UTF-8 Titles (resource utf8-title)
		     This controls whether xterm accepts UTF-8 encoding	for
		     title control sequences.  It corresponds to the utf8Fonts
		     resource.

		     Initially the checkmark is	set according to both the utf8
		     and utf8Fonts resource values.  If	the latter is set to
		     "always", the checkmark is	disabled.  Likewise, if	there
		     are no fonts given	in the utf8Fonts subresources, then
		     the checkmark also	is disabled.

		     The standard XTerm	app-defaults file defines both sets of
		     fonts, while the UXTerm app-defaults file defines only
		     one set.  Assuming	the standard app-defaults files, this
		     command will launch xterm able to switch between UTF-8
		     and ISO-8859-1 encoded fonts:

			 uxterm	-class XTerm

       The fourth section allows you to	enable or disable special operations
       which can be controlled by writing escape sequences to the terminal.
       These are disabled if the SendEvents feature is enabled:

	      Allow Color Ops (resource	allow-font-ops)
		     This corresponds to the allowColorOps resource.  Enable
		     or	disable	control	sequences that set/query the colors.

	      Allow Font Ops (resource allow-font-ops)
		     This corresponds to the allowFontOps resource.  Enable or
		     disable control sequences that set/query the font.

	      Allow Mouse Ops (resource	allow-mouse-ops)
		     Enable or disable control sequences that cause the
		     terminal to send escape sequences on pointer-clicks and
		     movement.	This corresponds to the	allowMouseOps
		     resource.

	      Allow Tcap Ops (resource allow-tcap-ops)
		     Enable or disable control sequences that query the
		     terminal's	notion of its function-key strings, as termcap
		     or	terminfo capabilities.	This corresponds to the
		     allowTcapOps resource.

	      Allow Title Ops (resource	allow-title-ops)
		     Enable or disable control sequences that modify the
		     window title or icon name.	 This corresponds to the
		     allowTitleOps resource.

	      Allow Window Ops (resource allow-window-ops)
		     Enable or disable extended	window control sequences (as
		     used in dtterm).  This corresponds	to the allowWindowOps
		     resource.

   Tek Options
       The xterm tekMenu sets various modes in the Tektronix emulation,	and is
       popped up when the "control" key	and pointer button two are pressed in
       the Tektronix window.  The current font size is checked in the modes
       section of the menu.

	      Large Characters (resource tektextlarge)

	      #2 Size Characters (resource tektext2)

	      #3 Size Characters (resource tektext3)

	      Small Characters (resource tektextsmall)

       Commands:

	      PAGE (resource tekpage)
		     Simulates the Tektronix "PAGE" button by

		     o	 clearing the window,

		     o	 cancelling the	graphics input-mode, and

		     o	 moving	the cursor to the home position.

	      RESET (resource tekreset)
		     Unlike the	similarly-named	Tektronix "RESET" button, this
		     does everything that PAGE does as well as resetting the
		     line-type and font-size to	their default values.

	      COPY (resource tekcopy)
		     Simulates the Tektronix "COPY" button (which makes	a
		     hard-copy of the screen) by writing the information to a
		     text file.

       Windows:

	      Show VT Window (resource vtshow)

	      Switch to	VT Mode	(resource vtmode)

	      Hide Tek Window (resource	tekhide)

SECURITY
       X environments differ in	their security consciousness.

       o   Most	servers, run under xdm,	are capable of using a "magic cookie"
	   authorization scheme	that can provide a reasonable level of
	   security for	many people.  If your server is	only using a host-
	   based mechanism to control access to	the server (see	xhost(1)),
	   then	if you enable access for a host	and other users	are also
	   permitted to	run clients on that same host, it is possible that
	   someone can run an application which	uses the basic services	of the
	   X protocol to snoop on your activities, potentially capturing a
	   transcript of everything you	type at	the keyboard.

       o   Any process which has access	to your	X display can manipulate it in
	   ways	that you might not anticipate, even redirecting	your keyboard
	   to itself and sending events	to your	application's windows.	This
	   is true even	with the "magic	cookie"	authorization scheme.  While
	   the allowSendEvents provides	some protection	against	rogue
	   applications	tampering with your programs, guarding against a
	   snooper is harder.

       o   The X input extension for instance allows an	application to bypass
	   all of the other (limited) authorization and	security features,
	   including the GrabKeyboard protocol.

       o   The possibility of an application spying on your keystrokes is of
	   particular concern when you want to type in a password or other
	   sensitive data.  The	best solution to this problem is to use	a
	   better authorization	mechanism than is provided by X.

       Subject to all of these caveats,	a simple mechanism exists for
       protecting keyboard input in xterm.

       The xterm menu (see MENUS above)	contains a Secure Keyboard entry
       which, when enabled, attempts to	ensure that all	keyboard input is
       directed	only to	xterm (using the GrabKeyboard protocol request).  When
       an application prompts you for a	password (or other sensitive data),
       you can enable Secure Keyboard using the	menu, type in the data,	and
       then disable Secure Keyboard using the menu again.

       o   This	ensures	that you know which window is accepting	your
	   keystrokes.

       o   It cannot ensure that there are no processes	which have access to
	   your	X display that might be	observing the keystrokes as well.

       Only one	X client at a time can grab the	keyboard, so when you attempt
       to enable Secure	Keyboard it may	fail.  In this case, the bell will
       sound.  If the Secure Keyboard succeeds,	the foreground and background
       colors will be exchanged	(as if you selected the	Enable Reverse Video
       entry in	the Modes menu); they will be exchanged	again when you exit
       secure mode.  If	the colors do not switch, then you should be very
       suspicious that you are being spoofed.  If the application you are
       running displays	a prompt before	asking for the password, it is safest
       to enter	secure mode before the prompt gets displayed, and to make sure
       that the	prompt gets displayed correctly	(in the	new colors), to
       minimize	the probability	of spoofing.  You can also bring up the	menu
       again and make sure that	a check	mark appears next to the entry.

       Secure Keyboard mode will be disabled automatically if your xterm
       window becomes iconified	(or otherwise unmapped), or if you start up a
       reparenting window manager (that	places a title bar or other decoration
       around the window) while	in Secure Keyboard mode.  (This	is a feature
       of the X	protocol not easily overcome.)	When this happens, the
       foreground and background colors	will be	switched back and the bell
       will sound in warning.

CHARACTER CLASSES
       Clicking	the left pointer button	twice in rapid succession (double-
       clicking) causes	all characters of the same class (e.g.,	letters, white
       space, punctuation) to be selected as a "word".	Since different	people
       have different preferences for what should be selected (for example,
       should filenames	be selected as a whole or only the separate subnames),
       the default mapping can be overridden through the use of	the charClass
       (class CharClass) resource.

       This resource is	a series of comma-separated range:value	pairs.

       o   The range is	either a single	number or low-high in the range	of 0
	   to 65535, corresponding to the code for the character or characters
	   to be set.

       o   The value is	arbitrary.  For	example, the default table uses	the
	   character number of the first character occurring in	the set.  When
	   not in UTF-8	mode, only the first 256 entries of this table will be
	   used.

       The default table starts	as follows -

	   static int charClass[256] = {
	   /* NUL  SOH	STX  ETX  EOT  ENQ  ACK	 BEL */
	       32,   1,	  1,   1,   1,	 1,   1,   1,
	   /*  BS   HT	 NL   VT   NP	CR   SO	  SI */
		1,  32,	  1,   1,   1,	 1,   1,   1,
	   /* DLE  DC1	DC2  DC3  DC4  NAK  SYN	 ETB */
		1,   1,	  1,   1,   1,	 1,   1,   1,
	   /* CAN   EM	SUB  ESC   FS	GS   RS	  US */
		1,   1,	  1,   1,   1,	 1,   1,   1,
	   /*  SP    !	  "    #    $	 %    &	   ' */
	       32,  33,	 34,  35,  36,	37,  38,  39,
	   /*	(    )	  *    +    ,	 -    .	   / */

	      For example, the string "33:48,37:48,45-47:48,38:48" indicates
	      that the exclamation mark, percent sign, dash, period, slash,
	      and ampersand characters should be treated the same way as
	      characters and numbers.  This is useful for cutting and pasting
	      electronic mailing addresses and filenames.

KEY BINDINGS
       It is possible to rebind	keys (or sequences of keys) to arbitrary
       strings for input, by changing the translations resources for the vt100
       or tek4014 widgets.  Changing the translations resource for events
       other than key and button events	is not expected, and will cause
       unpredictable behavior.

   Actions
       The following actions are provided for use within the vt100 or tek4014
       translations resources:

       allow-bold-fonts(on/off/toggle)
	       This action sets, unsets	or toggles the allowBoldFonts resource
	       and is also invoked by the allow-bold-fonts entry in fontMenu.

       allow-color-ops(on/off/toggle)
	       This action sets, unsets	or toggles the allowColorOps resource
	       and is also invoked by the allow-color-ops entry	in fontMenu.

       allow-font-ops(on/off/toggle)
	       This action sets, unsets	or toggles the allowFontOps resource
	       and is also invoked by the allow-font-ops entry in fontMenu.

       allow-mouse-ops(on/off/toggle)
	       This action sets, unsets	or toggles the allowMousepOps resource
	       and is also invoked by the allow-mouse-ops entry	in fontMenu.

       allow-send-events(on/off/toggle)
	       This action sets, unsets	or toggles the allowSendEvents
	       resource	and is also invoked by the allowsends entry in
	       mainMenu.

       allow-tcap-ops(on/off/toggle)
	       This action sets, unsets	or toggles the allowTcapOps resource
	       and is also invoked by the allow-tcap-ops entry in fontMenu.

       allow-title-ops(on/off/toggle)
	       This action sets, unsets	or toggles the allowTitleOps resource
	       and is also invoked by the allow-title-ops entry	in fontMenu.

       allow-window-ops(on/off/toggle)
	       This action sets, unsets	or toggles the allowWindowOps resource
	       and is also invoked by the allow-window-ops entry in fontMenu.

       alt-sends-escape()
	       This action toggles the state of	the altSendsEscape resource.

       bell([percent])
	       This action rings the keyboard bell at the specified percentage
	       above or	below the base volume.

       clear-saved-lines()
	       This action does	hard-reset() and also clears the history of
	       lines saved off the top of the screen.  It is also invoked from
	       the clearsavedlines entry in vtMenu.  The effect	is identical
	       to a hardware reset (RIS) control sequence.

       copy-selection(destname [, ...])
	       This action puts	the currently selected text into all of	the
	       selections or cutbuffers	specified by destname.	Unlike select-
	       end, it does not	send a mouse position or otherwise modify the
	       internal	selection state.

       create-menu(m/v/f/t)
	       This action creates one of the menus used by xterm, if it has
	       not been	previously created.  The parameter values are the menu
	       names: mainMenu,	vtMenu,	fontMenu, tekMenu, respectively.

       dabbrev-expand()
	       Expands the word	before cursor by searching in the preceding
	       text on the screen and in the scrollback	buffer for words
	       starting	with that abbreviation.	 Repeating dabbrev-expand()
	       several times in	sequence searches for an alternative expansion
	       by looking farther back.	 Lack of more matches is signaled by a
	       bell.  Attempts to expand an empty word (i.e., when cursor is
	       preceded	by a space) yield successively all previous words.
	       Consecutive identical expansions	are ignored.  The word here is
	       defined as a sequence of	non-whitespace characters.  This
	       feature partially emulates the behavior of "dynamic
	       abbreviation" expansion in Emacs	(bound there to	M-/).  Here is
	       a resource setting for xterm which will do the same thing:

		   *VT100*translations:	   #override \n\
			   Meta	<KeyPress> /:dabbrev-expand()

       deiconify()
	       Changes the window state	back to	normal,	if it was iconified.

       delete-is-del()
	       This action toggles the state of	the deleteIsDEL	resource.

       dired-button()
	       Handles a button	event (other than press	and release) by
	       echoing the event's position (i.e., character line and column)
	       in the following	format:

		   ^X ESC G <line+" "> <col+" ">

       dump-html()
	       Invokes the XHTML Screen	Dump feature.

       dump-svg()
	       Invokes the SVG Screen Dump feature.

       exec-formatted(format, sourcename [, ...])
	       Execute an external command, using the current selection	for
	       part of the command's parameters.  The first parameter, format
	       gives the basic command.	 Succeeding parameters specify the
	       selection source	as in insert-selection.

	       The format parameter allows these substitutions:

	       %%   inserts a "%".

	       %P   the	screen-position	at the beginning of the	highlighted
		    region, as a semicolon-separated pair of integers using
		    the	values that the	CUP control sequence would use.

	       %p   the	screen-position	after the beginning of the highlighted
		    region, using the same convention as "%P".

	       %S   the	length of the string that "%s" would insert.

	       %s   the	content	of the selection, unmodified.

	       %T   the	length of the string that "%t" would insert.

	       %t   the	selection, trimmed of leading/trailing whitespace.
		    Embedded spaces (and newlines) are copied as is.

	       %R   the	length of the string that "%r" would insert.

	       %r   the	selection, trimmed of trailing whitespace.

	       %V   the	video attributes at the	beginning of the highlighted
		    region, as a semicolon-separated list of integers using
		    the	values that the	SGR control sequence would use.

	       %v   the	video attributes after the end of the highlighted
		    region, using the same convention as "%V".

	       After constructing the command-string, xterm forks a subprocess
	       and executes the	command, which completes independently of
	       xterm.

	       For example, this translation would invoke a new	xterm process
	       to view a file whose name is selected while holding the shift
	       key down.  The new process is started when the mouse button is
	       released:

		   *VT100*translations:	#override Shift	\
		       <Btn1Up>:exec-formatted("xterm -e view '%t'", SELECT)

       exec-selectable(format, onClicks)
	       Execute an external command, using data copied from the screen
	       for part	of the command's parameters.  The first	parameter,
	       format gives the	basic command as in exec-formatted.  The
	       second parameter	specifies the method for copying the data as
	       in the on2Clicks	resource.

       fullscreen(on/off/toggle)
	       This action sets, unsets	or toggles the fullscreen resource.

       iconify()
	       Iconifies the window.

       hard-reset()
	       This action resets the scrolling	region,	tabs, window size, and
	       cursor keys and clears the screen.  It is also invoked from the
	       hardreset entry in vtMenu.

       ignore()
	       This action ignores the event but checks	for special pointer
	       position	escape sequences.

       insert()
	       This action inserts the character or string associated with the
	       key that	was pressed.

       insert-eight-bit()
	       This action inserts an eight-bit	(Meta) version of the
	       character or string associated with the key that	was pressed.
	       Only single-byte	values are treated specially.  The exact
	       action depends on the value of the altSendsEscape and the
	       metaSendsEscape and the eightBitInput resources.	 The
	       metaSendsEscape resource	is tested first.  See the
	       eightBitInput resource for a full discussion.

	       The term	"eight-bit" is misleading: xterm checks	if the key is
	       in the range 128	to 255 (the eighth bit is set).	 If the	value
	       is in that range, depending on the resource values, xterm may
	       then do one of the following:

	       o   add 128 to the value, setting its eighth bit,

	       o   send	an ESC byte before the key, or

	       o   send	the key	unaltered.

       insert-formatted(format,	sourcename [, ...])
	       Insert the current selection or data related to it, formatted.
	       The first parameter, format gives the template for the data as
	       in exec-formatted.  Succeeding parameters specify the selection
	       source as in insert-selection.

       insert-selectable(format, onClicks)
	       Insert data copied from the screen, formatted.  The first
	       parameter, format gives the template for	the data as in exec-
	       formatted.  The second parameter	specifies the method for
	       copying the data	as in the on2Clicks resource.

       insert-selection(sourcename [, ...])
	       This action inserts the string found in the selection or
	       cutbuffer indicated by sourcename.  Sources are checked in the
	       order given (case is significant) until one is found.
	       Commonly-used selections	include: PRIMARY, SECONDARY, and
	       CLIPBOARD.  Cut buffers are typically named CUT_BUFFER0 through
	       CUT_BUFFER7.

       insert-seven-bit()
	       This action is a	synonym	for insert().  The term	"seven-bit" is
	       misleading: it only implies that	xterm does not try to add 128
	       to the key's value as in	insert-eight-bit().

       interpret(control-sequence)
	       Interpret the given control sequence locally, i.e., without
	       passing it to the host.	This works by inserting	the control
	       sequence	at the front of	the input buffer.  Use "\" to escape
	       octal digits in the string.  Xt does not	allow you to put a
	       null character (i.e., "\000") in	the string.

       keymap(name)
	       This action dynamically defines a new translation table whose
	       resource	name is	name with the suffix "Keymap" (i.e.,
	       nameKeymap, where case is significant).	The name None restores
	       the original translation	table.

       larger-vt-font()
	       Set the font to the next	larger one, based on the font
	       dimensions.  See	also set-vt-font().

       load-vt-fonts(name[,class])
	       Load fontnames from the given subresource name and class.  That
	       is, load	the "*VT100.name.font",	resource as "*VT100.font" etc.
	       If no name is given, the	original set of	fontnames is restored.

	       Unlike set-vt-font(), this does not affect the escape- and
	       select-fonts, since those are not based on resource values.  It
	       does affect the fonts loosely organized under the "Default"
	       menu entry, including font, boldFont, wideFont and
	       wideBoldFont.

       maximize()
	       Resizes the window to fill the screen.

       meta-sends-escape()
	       This action toggles the state of	the metaSendsEscape resource.

       popup-menu(menuname)
	       This action displays the	specified popup	menu.  Valid names
	       (case is	significant) include:  mainMenu, vtMenu, fontMenu, and
	       tekMenu.

       print(printer-flags)
	       This action prints the window.  It is also invoked by the print
	       entry in	mainMenu.

	       The action accepts optional parameters, which temporarily
	       override	resource settings.  The	parameter values are matched
	       ignoring	case:

	       noFormFeed
		    no form feed will be sent at the end of the	last line
		    printed (i.e., printerFormFeed is "false").

	       FormFeed
		    a form feed	will be	sent at	the end	of the last line
		    printed (i.e., printerFormFeed is "true").

	       noNewLine
		    no newline will be sent at the end of the last line
		    printed, and wrapped lines will be combined	into long
		    lines (i.e., printerNewLine	is "false").

	       NewLine
		    a newline will be sent at the end of the last line
		    printed, and each line will	be limited (by adding a
		    newline) to	the screen width (i.e.,	printerNewLine is
		    "true").

	       noAttrs
		    the	page is	printed	without	attributes (i.e.,
		    printAttributes is "0").

	       monoAttrs
		    the	page is	printed	with monochrome	(vt220)	attributes
		    (i.e., printAttributes is "1").

	       colorAttrs
		    the	page is	printed	with ANSI color	attributes (i.e.,
		    printAttributes is "2").

       print-everything(printer-flags)
	       This action sends the entire text history, in addition to the
	       text currently visible, to the program given in the
	       printerCommand resource.	 It allows the same optional
	       parameters as the print action.	With a suitable	printer
	       command,	the action can be used to load the text	history	in an
	       editor.

       print-immediate()
	       Sends the text of the current window directly to	a file,	as
	       specified by the	printFileImmediate, printModeImmediate and
	       printOptsImmediate resources.

       print-on-error()
	       Toggles a flag telling xterm that if it exits with an X error,
	       to send the text	of the current window directly to a file, as
	       specified by the	printFileOnXError, printModeOnXError and
	       printOptsOnXError resources.

       print-redir()
	       This action toggles the printerControlMode between 0 and	2.
	       The corresponding popup menu entry is useful for	switching the
	       printer off if you happen to change your	mind after deciding to
	       print random binary files on the	terminal.

       quit()
	       This action sends a SIGHUP to the subprogram and	exits.	It is
	       also invoked by the quit	entry in mainMenu.

       readline-button()
	       Supports	the optional readline feature by echoing repeated
	       cursor forward or backward control sequences on button release
	       event, to request that the host application update its notion
	       of the cursor's position	to match the button event.

       redraw()
	       This action redraws the window.	It is also invoked by the
	       redraw entry in mainMenu.

       restore()
	       Restores	the window to the size before it was last maximized.

       scroll-back(count [,units [,mouse] ])
	       This action scrolls the text window backward so that text that
	       had previously scrolled off the top of the screen is now
	       visible.

	       The count argument indicates the	number of units	(which may be
	       page, halfpage, pixel, or line) by which	to scroll.  If no
	       count parameter is given, xterm uses the	number of lines	given
	       by the scrollLines resource.

	       An adjustment can be specified for the page or halfpage units
	       by appending a "+" or "-" sign followed by a number, e.g.,
	       page-2 to specify 2 lines less than a page.

	       If the second parameter is omitted "lines" is used.

	       If the third parameter mouse is given, the action is ignored
	       when mouse reporting is enabled.

       scroll-forw(count [,units [,mouse] ])
	       This action is similar to scroll-back except that it scrolls in
	       the other direction.

       secure()
	       This action toggles the Secure Keyboard mode (see SECURITY),
	       and is invoked from the securekbd entry in mainMenu.

       scroll-lock(on/off/toggle)
	       This action sets, unsets	or toggles internal state which	tells
	       xterm whether Scroll Lock is active, subject to the

       spawn-new-terminal(params)
	       Spawn a new xterm process.  This	is available on	systems	which
	       have a modern version of	the process filesystem,	e.g., "/proc",
	       which xterm can read.

	       Use the "cwd" process entry, e.g., /proc/12345/cwd to obtain
	       the working directory of	the process which is running in	the
	       current xterm.

	       On systems which	have the "exe" process entry, e.g.,
	       /proc/12345/exe,	use this to obtain the actual executable.
	       Otherwise, use the $PATH	variable to find xterm.

	       If parameters are given in the action, pass them	to the new
	       xterm process.

       string(string)
	       This action inserts the specified text string as	if it had been
	       typed.  Quotation is necessary if the string contains
	       whitespace or non-alphanumeric characters.  If the string
	       argument	begins with the	characters "0x", it is interpreted as
	       a hex character constant.

       tek-copy()
	       This action copies the escape codes used	to generate the
	       current window contents to a file in the	current	directory
	       beginning with the name COPY.  It is also invoked from the
	       tekcopy entry in	tekMenu.

	       the tekreset entry in tekMenu.

       vi-button()
	       Handles a button	event (other than press	and release) by
	       echoing a control sequence computed from	the event's line
	       number in the screen relative to	the current line:

		   ESC ^P

	       or

		   ESC ^N

	       according to whether the	event is before, or after the current
	       line, respectively.  The	^N (or ^P) is repeated once for	each
	       line that the event differs from	the current line.  The control
	       sequence	is omitted altogether if the button event is on	the
	       current line.

       visual-bell()
	       This action flashes the window quickly.

       The Tektronix window also has the following action:

       gin-press(l/L/m/M/r/R)
	       This action sends the indicated graphics	input code.

   Custom Key Bindings
       You can modify the translations resource	by overriding parts of it, or
       merging your resources with it.

       Here is an example which	uses shifted select/paste to copy to the
       clipboard, and unshifted	select/paste for the primary selection.	 In
       each case, a (different)	cut buffer is also a target or source of the
       select/paste operation.	It is important	to remember however, that cut
       buffers store data in ISO-8859-1	encoding, while	selections can store
       data in a variety of formats and	encodings.  While xterm	owns the
       selection, it highlights	it.  When it loses the selection, it removes
       the corresponding highlight.  But you can still paste from the
       corresponding cut buffer.

	   *VT100*translations:	   #override \n\
	      ~Shift~Ctrl<Btn2Up>: insert-selection(PRIMARY, CUT_BUFFER0) \n\
	       Shift~Ctrl<Btn2Up>: insert-selection(CLIPBOARD, CUT_BUFFER1) \n\
	      ~Shift	 <BtnUp> : select-end(PRIMARY, CUT_BUFFER0) \n\
	       Shift	 <BtnUp> : select-end(CLIPBOARD, CUT_BUFFER1)

       In the example, the class name VT100 is used rather than	the widget
       name.  These are	different; a class name	could apply to more than one
       widget.	A leading "*" is used because the widget hierarchy above the
       vt100 widget depends on whether the toolbar support is compiled into
       xterm.

       Most of the predefined translations are related to the mouse, with a
       few that	use some of the	special	keys on	the keyboard.  Applications
       use special keys	(function-keys,	cursor-keys, keypad-keys) with
       modifiers (shift, control, alt).	 If xterm defines a translation	for a
       given combination of special key	and modifier, that makes it
       unavailable for use by applications within the terminal.	 For instance,
       one might extend	the use	of Page	Up and Page Down keys seen here:

	       Shift <KeyPress>	Prior :	scroll-back(1,halfpage)	\n\
	       Shift <KeyPress>	Next  :	scroll-forw(1,halfpage)	\n\

       to the Home and End keys:

	       Shift <KeyPress>	Home : scroll-to(begin)	\n\
	       Shift <KeyPress>	End  : scroll-to(end)

       but then	shift-Home and shift-End would then be unavailable to
       applications.

       Not everyone finds the three-button mouse bindings easy to use.	In a
       wheel mouse, the	middle button might be the wheel.  As an alternative,
       you could add a binding using shifted keys:

	   *VT100*translations:	     #override \n\
	       Shift <Key>Home:	   copy-selection(SELECT) \n\
	       Shift <Key>Insert:  copy-selection(SELECT) \n\
	       Ctrl Shift <Key>C:  copy-selection(SELECT) \n\
	       Ctrl Shift <Key>V:  insert-selection(SELECT)

       You would still use the left- and right-mouse buttons (typically	1 and
       3) for beginning	and extending selections.

       Besides mouse problems, there are also keyboards	with inconvenient
       layouts.	 Some lack a numeric keypad, making it hard to use the shifted
       keypad plus and minus bindings for switching between font sizes.	 You
       can work	around that by assigning the actions to	more readily accessed
       keys:

	   *VT100*translations:	     #override \n\
	       Ctrl <Key> +:	   larger-vt-font() \n\
	       Ctrl <Key> -:	   smaller-vt-font()

       The keymap feature allows you to	switch between sets of translations.
       The sample below	shows how the keymap() action may be used to add
       special keys for	entering commonly-typed	words:

	   *VT100.Translations:	#override <Key>F13: keymap(dbx)
	   *VT100.dbxKeymap.translations: \
		   <Key>F14:	   keymap(None)	\n\
		   <Key>F17:	   string("next") \n\
				   string(0x0d)	\n\
		   <Key>F18:	   string("step") \n\
				   string(0x0d)	\n\
		   <Key>F19:	   string("continue") \n\
				   string(0x0d)	\n\
		   <Key>F20:	   string("print ") \n\
				   insert-selection(PRIMARY, CUT_BUFFER0)

   Default Scrollbar Bindings
       Key bindings are	normally associated with the vt100 or tek4014 widgets
       which act as terminal emulators.	 Xterm's scrollbar (and	toolbar	if it
       is configured) are separate widgets.  Because all of these use the X
       Toolkit,	they have corresponding	translations resources.	 Those
       resources are distinct, and match different patterns, e.g., the
       differences in widget-name and number of	levels of widgets which	they
       may contain.

       The scrollbar widget is a child of the vt100 widget.  It	is positioned
       on top of the vt100 widget.  Toggling the scrollbar on and off causes
       the vt100 widget	to resize.

       The default bindings for	the scrollbar widget use only mouse-button
       events:

	      <Btn5Down>: StartScroll(Forward) \n\
	      <Btn1Down>: StartScroll(Forward) \n\
	      <Btn2Down>: StartScroll(Continuous) MoveThumb() NotifyThumb() \n\
	      <Btn3Down>: StartScroll(Backward)	\n\
	      <Btn4Down>: StartScroll(Backward)	\n\
	      <Btn2Motion>: MoveThumb()	NotifyThumb() \n\
	      <BtnUp>:	  NotifyScroll(Proportional) EndScroll()

       Events which the	scrollbar widget does not recognize at all are lost.

       However,	at startup, xterm augments these translations with the default
       translations used for the vt100 widget, together	with the resource
       "actions" which those translations use.	Because	the scrollbar (or
       menubar)	widgets	do not recognize these actions (but because it has a
       corresponding translation), they	are passed on to the vt100 widget.

       This augmenting of the scrollbar's translations has a few limitations:

       o   Xterm knows what the	default	translations are, but there is no
	   suitable library interface for determining what customizations a
	   user	may have added to the vt100 widget.  All that xterm can	do is
	   augment the scrollbar widget	to give	it the same starting point for
	   further customization by the	user.

       o   Events in the gap between the widgets may be	lost.

       o   Compose sequences begun in one widget cannot	be completed in	the
	   other, because the input methods for	each widget do not share
	   context information.

       Most customizations of the scrollbar translations do not	concern	key
       bindings.  Rather, users	are generally more interested in changing the
       bindings	of the mouse buttons.  For example, some people	prefer using
       the left	pointer	button for dragging the	scrollbar thumb.  That can be
       set up by altering the translations resource, e.g.,

	   *VT100.scrollbar.translations:  #override \n\
	      <Btn5Down>:     StartScroll(Forward) \n\
	      <Btn1Down>:     StartScroll(Continuous) MoveThumb() NotifyThumb()	\n\
	      <Btn4Down>:     StartScroll(Backward) \n\
	      <Btn1Motion>:   MoveThumb() NotifyThumb()	\n\
	      <BtnUp>:	      NotifyScroll(Proportional) EndScroll()

CONTROL	SEQUENCES AND KEYBOARD
       Applications can	send sequences of characters to	the terminal to	change
       its behavior.  Often they are referred to as "ANSI escape sequences" or
       just plain "escape sequences" but both terms are	misleading:

       o   ANSI	x3.64 (obsolete) which was replaced by ISO 6429	(ECMA-48) gave
	   rules for the format	of these sequences of characters.

       o   While the original VT100 was	claimed	to be ANSI-compatible (against
	   x3.64), there is no freely available	version	of the ANSI standard
	   to show where the VT100 differs.  Most of the documents which
	   mention the ANSI standard have additions not	found in the original
	   (such as those based	on ansi.sys).  So this discussion focuses on
	   the ISO standards.

       o   The standard	describes only sequences sent from the host to the
	   terminal.  There is no standard for sequences sent by special keys
	   from	the terminal to	the host.  By convention (and referring	to
	   existing terminals),	the format of those sequences usually conforms
	   to the host-to-terminal standard.

       o   Some	of xterm's sequences do	not fit	into the standard scheme.
	   Technically those are "unspecified".	 As an example,	DEC Screen
	   Alignment Test (DECALN) is this three-character sequence:

	       ESC # 8

       o   Some	sequences fit into the standard	format,	but are	not listed in
	   the standard.  These	include	the sequences used for setting up
	   scrolling margins and doing forward/reverse scrolling.

       o   Some	of the sequences (in particular, the single-character
	   functions such as tab and backspace)	do not include the escape
	   character.

       With all	of that	in mind, the standard refers to	these sequences	of
       characters as "control sequences".

       Xterm Control Sequences lists the control sequences which an
       application can send xterm to make it perform various operations.  Most
       of these	operations are standardized, from either the DEC or Tektronix
       terminals, or from more widely used standards such as ISO-6429.

       A few examples of usage are given in this section.

   Window and Icon Titles
       Some scripts use	echo with options -e and -n to tell the	shell to
       interpret the string "\e" as the	escape character and to	suppress a
       trailing	newline	on output.  Those are not portable, nor	recommended.
       Instead,	use printf (POSIX).

       For example, to set the window title to "Hello world!", you could use
       one of these commands in	a script:

	   printf '\033]2;Hello	world!\033\'
	   printf '\033]2;Hello	world!\007'
	   printf '\033]2;%s\033\' "Hello world!"
	   printf '\033]2;%s\007' "Hello world!"

       The printf command interprets the octal value "\033" for	escape,	and
       (since it was not given in the format) omits a trailing newline from
       the output.

       Some programs (such as screen(1)) set both window- and icon-titles at
       the same	time, using a slightly different control sequence:

	   printf '\033]0;Hello	world!\033\'
	   printf '\033]0;Hello	world!\007'
	   printf '\033]0;%s\033\' "Hello world!"
	   printf '\033]0;%s\007' "Hello world!"

       The difference is the parameter "0" in each command.  Most window
       managers	will honor either window title or icon title.  Some will make
       a distinction and allow you to set just the icon	title.	You can	tell
       xterm to	ask for	this with a different parameter	in the control
       sequence:

	   printf '\033]1;Hello	world!\033\'
	   printf '\033]1;Hello	world!\007'
	   printf '\033]1;%s\033\' "Hello world!"
	   printf '\033]1;%s\007' "Hello world!"

   Special Keys
       Xterm, like any VT100-compatible	terminal emulator, has two modes for
       the special keys	(cursor-keys, numeric keypad, and certain function-
       keys):

       o   normal mode,	which makes the	special	keys transmit "useful"
	   sequences such as the control sequence for cursor-up	when pressing
	   the up-arrow, and

       o   application mode, which uses	a different control sequence that
	   cannot be mistaken for the "useful" sequences.

       The main	difference between the two modes is that normal	mode sequences
       start with CSI (escape [) and application mode sequences	start with SS3
       (escape O).

       The terminal is initialized into	one of these two modes (usually	the
       normal mode), based on the terminal description (termcap	or terminfo).
       The terminal description	also has capabilities (strings)	defined	for
       the keypad mode used in curses applications.

       There is	a problem in using the terminal	description for	applications
       that are	not intended to	be full-screen curses applications: the
       definitions of special keys are only correct for	this keypad mode.  For
       example,	some shells (unlike ksh(1), which appears to be	hard-coded,
       not even	using termcap) allow their users to customize key-bindings,
       assigning shell actions to special keys.

       o   bash(1) allows constant strings to be assigned to functions.	 This
	   is only successful if the terminal is initialized to	application
	   mode	by default, because bash lacks flexibility in this area.  It
	   uses	a (less	expressive than	bash's)	readline scripting language
	   for setting up key bindings,	which relies upon the user to
	   statically enumerate	the possible bindings for given	values of
	   $TERM.

       o   zsh(1) provides an analogous	feature, but it	accepts	runtime
	   expressions,	as well	as providing a $terminfo array for scripts.
	   In particular, one can use the terminal database, transforming when
	   defining a key-binding.  By transforming the	output so that CSI and
	   SS3 are equated, zsh	can use	the terminal database to obtain	useful
	   definitions for its command-line use	regardless of whether the
	   terminal uses normal	or application mode initially.	Here is	an
	   example:

	       [[ "$terminfo[kcuu1]" ==	"^[O"* ]] && \
	       bindkey -M viins	"${terminfo[kcuu1]/O/[}" \
	       vi-up-line-or-history

   Changing Colors
       A few shell programs provide the	ability	for users to add color and
       other video attributes to the shell prompt strings.  Users can do this
       by setting $PS1 (the primary prompt string).  Again, bash and zsh have
       provided	features not found in ksh.  There is a problem,	however: the
       prompt's	width on the screen will not necessarily be the	same as	the
       number of characters.  Because there is no guidance in the POSIX
       standard, each shell addresses the problem in a different way:

       o   bash	treats characters within "\[" and "\]" as nonprinting (using
	   no width on the screen).

       o   zsh treats characters within	"%{" and "%}" as nonprinting.

       In addition to the difference in	syntax,	the shells provide different
       methods for obtaining useful escape sequences:

       o   As noted in Special Keys, zsh initializes the $terminfo array with
	   the terminal	capabilities.

	   It also provides a function echoti which works like tput(1) to
	   convert a terminal capability with its parameters into a string
	   that	can be written to the terminal.

       o   Shells lacking a comparable feature (such as	bash) can always use
	   the program tput to do this transformation.

       Hard-coded escape sequences are supported by each shell,	but are	not
       recommended because those rely upon particular configurations and
       cannot be easily	moved between different	user environments.

ENVIRONMENT
       Xterm sets several environment variables.

   System Independent
       Some variables are used on every	system:

       DISPLAY
	    is the display name, pointing to the X server (see DISPLAY NAMES
	    in X(1)).

       TERM
	    is set according to	the terminfo (or termcap) entry	which it is
	    using as a reference.

	    On some systems, you may encounter situations where	the shell
	    which you use and xterm are	built using libraries with different
	    terminal databases.	 In that situation, xterm may choose a
	    terminal description not known to the shell.

       WINDOWID
	    is set to the X window id number of	the xterm window.

       XTERM_FILTER
	    is set if a	locale-filter is used.	The value is the pathname of
	    the	filter.

       XTERM_LOCALE
	    shows the locale which was used by xterm on	startup.  Some shell
	    initialization scripts may set a different locale.

       XTERM_SHELL
	    is set to the pathname of the program which	is invoked.  Usually
	    that is a shell program, e.g., /bin/sh.  Since it is not
	    necessarily	a shell	program	however, it is distinct	from "SHELL".

       XTERM_VERSION
	    is set to the string displayed by the -version option.  That is
	    normally an	identifier for the X Window libraries used to build
	    xterm, followed by xterm's patch number in parenthesis.  The patch
	    number is also part	of the response	to a Secondary Device
	    Attributes (DA) control sequence (see Xterm	Control	Sequences).

   System Dependent
       Depending on your system	configuration, xterm may also set the
       following:

       COLUMNS
	    the	width of the xterm in characters (cf: "stty columns").

	    When this variable is set, curses applications (and	most terminal
	    programs) will assume that the terminal has	this many columns.

	    Xterm would	do this	for systems which have no ability to tell the
	    size of the	terminal.  Those are very rare,	none newer than	the
	    mid	1990s when SVR4	became prevalent.

       HOME
	    when xterm is configured (at build-time) to	update utmp.

       LINES
	    the	height of the xterm in characters (cf: "stty rows").

	    When this variable is set, curses applications (and	most terminal
	    programs) will assume that the terminal has	this many lines
	    (rows).

	    Xterm would	do this	for systems which have no ability to tell the
	    size of the	terminal.  Those are very rare,	none newer than	the
	    mid	1990s when SVR4	became prevalent.

       LOGNAME
	    when xterm is configured (at build-time) to	update utmp.

	    Your configuration may have	set LOGNAME; xterm does	not modify
	    that.  If it is unset, xterm will use USER if it is	set.  Finally,
	    if neither is set, xterm will use the getlogin(3) function.

       SHELL
	    when xterm is configured (at build-time) to	update utmp.  It is
	    also set if	you provide a valid shell name as the optional
	    parameter.

	    Xterm sets this to an absolute pathname.  If you have set the
	    variable to	a relative pathname, xterm may set it to a different
	    shell pathname.

	    If you have	set this to an pathname	which does not correspond to a
	    valid shell, xterm may unset it, to	avoid confusion.

       TERMCAP
	    the	contents of the	termcap	entry corresponding to $TERM, with
	    lines and columns values substituted for the actual	size window
	    you	have created.

	    This feature is, like LINES	and COLUMNS, used rarely.  It
	    addresses the same limitation of a few older systems by providing
	    a way for termcap-based applications to get	the initial screen
	    size.

       TERMINFO
	    may	be defined to a	nonstandard location using the configure
	    script.

WINDOW PROPERTIES
       In the output from xprop(1), there are several properties.

   Properties set by X Toolkit
       WM_CLASS
	    This shows the instance name and the X resource class, passed to X
	    Toolkit during initialization of xterm, e.g.,

		WM_CLASS(STRING) = "xterm", "UXTerm"

       WM_CLIENT_LEADER
	    This shows the window-id which xterm provides with an environment
	    variable (WINDOWID), e.g.,

		WM_CLIENT_LEADER(WINDOW): window id # 0x800023

       WM_COMMAND
	    This shows the command-line	arguments for xterm which are passed
	    to X Toolkit during	initialization,	e.g.,

		WM_COMMAND(STRING) = { "xterm",	"-class", "UXTerm", "-title", "uxterm",	"-u8" }

       WM_ICON_NAME
	    This holds the icon	title, which different window managers handle
	    in various ways.  It is set	via the	iconName resource.
	    Applications can change this using control sequences.

       WM_LOCALE_NAME
	    This shows the result from the setlocale(3)	function for the
	    LC_CTYPE category, e.g.,

		WM_LOCALE_NAME(STRING) = "en_US.UTF-8"

       WM_NAME
	    This holds the window title, normally at the top of	xterm's
	    window.  It	is set via the title resource.	Applications can
	    change this	using control sequences.

   Properties set by Xterm
       X Toolkit does not manage EWMH properties.  Xterm does this directly.

       _NET_WM_ICON_NAME
	    stores the icon name.

       _NET_WM_NAME
	    stores the title string.

       _NET_WM_PID
	    stores the process identifier for xterm's display.

   Properties used by Xterm
       _NET_SUPPORTED
	    Xterm checks this property on the supporting window	to decide if
	    the	window manager supports	specific maximizing styles.  That may
	    include other window manager hints;	xterm uses the X library calls
	    to manage those.

       _NET_SUPPORTING_WM_CHECK
	    Xterm checks this to ensure	that it	will only update the EWMH
	    properties for a window manager which claims EWMH compliance.

       _NET_WM_STATE
	    This tells xterm whether its window	has been maximized by the
	    window manager, and	if so, what type of maximizing:

	    _NET_WM_STATE_FULLSCREEN

	    _NET_WM_STATE_MAXIMIZED_HORZ

	    _NET_WM_STATE_MAXIMIZED_VERT

FILES
       The actual pathnames given may differ on	your system.

       /etc/shells
	    contains a list of valid shell programs, used by xterm to decide
	    if the "SHELL" environment variable	should be set for the process
	    started by xterm.

	    On systems which have the getusershell function, xterm will	use
	    that function rather than directly reading the file, since the
	    file may not be present if the system uses default settings.

       /etc/utmp
	    the	system log file, which records user logins.

       /etc/wtmp
	    the	system log file, which records user logins and logouts.

       /usr/local/lib/X11/app-defaults/XTerm
	    the	xterm default application resources.

       /usr/local/lib/X11/app-defaults/XTerm-color
	    the	xterm color application	resources.  If your display supports
	    color, use this

		*customization:	-color

	    in your .Xdefaults file to automatically use this resource file
	    rather than	/usr/local/lib/X11/app-defaults/XTerm.	If you do not
	    do this, xterm uses	its compiled-in	default	resource settings for
	    colors.

       /usr/local/share/pixmaps
	    the	directory in which xterm's pixmap icon files are installed.

ERROR MESSAGES
       Most of the fatal error messages	from xterm use the following format:

	   xterm: Error	XXX, errno YYY:	ZZZ

       The XXX codes (which are	used by	xterm as its exit-code)	are listed
       below, with a brief explanation.

       1    is used for	miscellaneous errors, usually accompanied by a

BUGS
       Large pastes do not work	on some	systems.  This is not a	bug in xterm;
       it is a bug in the pseudo terminal driver of those systems.  Xterm
       feeds large pastes to the pty only as fast as the pty will accept data,
       but some	pty drivers do not return enough information to	know if	the
       write has succeeded.

       When connected to an input method, it is	possible for xterm to hang if
       the XIM server is suspended or killed.

       Many of the options are not resettable after xterm starts.

       This program still needs	to be rewritten.  It should be split into very
       modular sections, with the various emulators being completely separate
       widgets that do not know	about each other.  Ideally, you'd like to be
       able to pick and	choose emulator	widgets	and stick them into a single
       control widget.

       There needs to be a dialog box to allow entry of	the Tek	COPY file
       name.

       Extended	Window Manager Hints (EWMH),
       X Desktop Group (version	1.3, 2005).

       EWMH uses UTF8_STRING pervasively without defining it, but does mention
       the ICCCM.  Version 2.0 of the ICCCM does not address UTF-8.   That  is
       an extension added in XFree86.

       o   Markus Kuhn summarized this in UTF-8	and Unicode FAQ	for Unix/Linux
	   (2001), in the section "Is X11 ready	for Unicode?"

	   https://www.cl.cam.ac.uk/~mgk25/unicode.html

       o   Juliusz Chroboczek  proposed	 the  UTF8_STRING  selection  atom  in
	   1999/2000, which became part	of the ICCCM in	XFree86.

	   https://www.irif.fr/~jch/software/UTF8_STRING/

	   An  Xorg  developer	removed	that part of the documentation in 2004
	   when	incorporating other work from XFree86 into Xorg.  The  feature
	   is still supported in Xorg, though undocumented as of 2019.
