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	termi-
       nals  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 capabili-
       ties (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),  Tek-
       tronix graphics will be restricted to the largest box with a 4014's as-
       pect ratio that will fit	in the window.	This box is located in the up-
       per 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	termi-
       nal output.  This is the	window that contains the text cursor.  The ac-
       tive window can be chosen through escape	sequences,  the	 "VT  Options"
       menu  in	 the VTxxx window, and the "Tek	Options" menu in the 4014 win-
       dow.

EMULATIONS
       The VT102 emulation is fairly complete, but does	 not  support  autore-
       peat.   Double-size  characters	are  displayed	properly  if your font
       server supports scalable	fonts.	The VT220 emulation does  not  support
       soft fonts, it is otherwise complete.

       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" and the "TERMCAP" environment
       variables.  You may also	use "vt220",  but must set the terminal	emula-
       tion  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 con-
       trol through a set of escape  sequences	different  from	 the  standard
       VT102 escape sequences.	(See the Xterm Control Sequences document.)

       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	direc-
       tory xterm is started in, or the	home directory for a login xterm).

       Not all of the features described in this manual	are necessarily	avail-
       able  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 VT102	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 ter-
       minal 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 al-
       ternate screens for cut and paste.

       In either VT102 or Tektronix mode, there	are escape sequences to	change
       the name	of the windows.	 Additionally, in VT102	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 (cur-
       rently button-press and release events, and  button-motion  events)  as
       keyboard	control	sequences.  See	Xterm Control Sequences	for details.

OPTIONS
       The xterm terminal emulator accepts the standard	X Toolkit command line
       options as well as many application-specific options.   If  the	option
       begins  with  a `+' instead of a	`-', the option	is restored to its de-
       fault value.

       -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	gener-
	       ates 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 un-
	       known 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.

       Most of the xterm options are actually parsed by	the X  Toolkit,	 which
       sets resource values.  Xterm provides the X Toolkit with	a table	of op-
       tions.  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.

       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  re-
       source 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, 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 op-
	   tions, some are deemed more important, and can override  other  op-
	   tions.

	   The	X Toolkit uses patterns	(constants and wildcards) to match re-
	   sources.  Once a particular pattern has been	used, it will not mod-
	   ify	it.  To	override a given setting, a more-specific pattern must
	   be used, e.g., replacing "*"	with ".".   Some  poorly-designed  re-
	   source  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, -B) 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  be-
	   fore, 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  pa-
       rameters	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 be-
	       tween 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 cur-
	       sor whenever the	focus is lost or the pointer leaves  the  win-
	       dow.

       +ah     This  option  indicates	that xterm should do text cursor high-
	       lighting	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
	       "false".

	       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  al-
	       lowed, and is equivalent	to setting the vt100 resource autoWrap
	       to "false".

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

       +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 dis-
	       play  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  the	 section  specifying character
	       classes and discussion of the charClass resource.

       -cjk_width
	       Set the cjkWidth	resource to "true".  When turned  on,  charac-
	       ters  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 pro-
	       grams 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.

       -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 se-
	       quences.	 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	param-
	       eter.

       -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 col-
	       ors:  the vt100 foreground and background colors, its text cur-
	       sor 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 dy-
	       namicColors option to "false".

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

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

       -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.

	       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 com-
	       piled 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 man-
	       ager  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  dou-
	       ble-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 re-
	       source 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	selec-
	       tion.  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	selec-
	       tion.  It sets the highlightColorMode resource to "false".

       -hold   Turn on the hold	resource, i.e.,	xterm will not immediately de-
	       stroy its window	when the shell	command	 completes.   It  will
	       wait  until you use the window manager to destroy/kill the win-
	       dow, 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 de-
	       stroy its window	when the shell command completes.

       -ie     Turn on the ptyInitialErase resource, i.e., use the pseudo-ter-
	       minal'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	refer-
	       ence, 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 hexadec-
	       imal,  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  al-
	       lowSendEvents 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 dis-
	       play  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 be-
	       hind.  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 fea-
	       ture on or off.

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

       -k8     This option  sets  the  allowC1Printable	 resource.   When  al-
	       lowC1Printable  is  set,	xterm overrides	the mapping of C1 con-
	       trol 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 hp-
	       FunctionKeys, scoFunctionKeys,  sunFunctionKeys,	 tcapFunction-
	       Keys,  oldXtermFKeys and	sunKeyboard, using the Sun/PC keyboard
	       layout.

       -l      Turn logging on.	 Normally logging is not supported, due	to se-
	       curity  concerns.   Some	versions of xterm may have logging en-
	       abled.  The logfile is written  to  the	directory  from	 which
	       xterm is	invoked.  The filename is generated, 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	corre-
	       sponds 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.  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 lo-
	       gin  shell  -  the  user's shell	of choice need not be a	Bourne
	       shell after all.	 Also, xterm -e	is supposed to provide a  con-
	       sistent functionality for other applications that need to start
	       text-mode programs in a window, and if loginShell were not  ig-
	       nored, 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  se-
	       lections.

       -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 cur-
	       sor.  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 bold-
	       Colors 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-colors
	       Print a report to the standard output showing information about
	       colors  as  xterm  allocates them.  This	corresponds to the re-
	       portColors resource.

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

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

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

       +rvc    This  option enables the	display	of characters with reverse at-
	       tribute as color.

       -rw     This option indicates that  reverse-wraparound  should  be  al-
	       lowed.	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 al-
	       lowed.

       -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  re-
	       quest  would have no effect: the	name is	not changed.  This has
	       the advantage of	preventing flicker and the disadvantage	of re-
	       quiring	an extra round trip to the server to find out the pre-
	       vious 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 Op-
	       tions" 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  discus-
	       sion of the scaleHeight resource.

       -si     This  option indicates that output to a window should not auto-
	       matically reposition the	screen to the bottom of	the  scrolling
	       region.	 This option can be turned on and off from the "VT Op-
	       tions" 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 "64".

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

       +sm     This option indicates that xterm	should not set up session man-
	       ager 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	VT102 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 or-
	       der for these entries and then sets the "TERM" and  the	"TERM-
	       CAP" environment	variables.

       +t      This option indicates that xterm	should start in	VT102 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  se-
	       quence.	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 func-
	       tions, 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	termi-
	       nal 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 re-
	       source  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  en-
	       coding  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 op-
	       tion 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, dis-
	       ables the display of characters	with  underline	 attribute  as
	       italics rather than with	underlining.

       +ulit   This  option,  corresponding  to	the italicULMode resource, en-
	       ables 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 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	start-
	       ing 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 ti-
	       tles.  Most window managers will	 detect	 this  change  immedi-
	       ately,  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 con-
	       sole 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  spe-
	       cialized	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 op-
	       tion 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

		   -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 de-
	       scriptor	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  "*tekGe-
	       ometry" resource.

       #geom   This  option  specifies the preferred position of the icon win-
	       dow.  It	is shorthand for specifying  the  "*iconGeometry"  re-
	       source.

       -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	 (see  below).
	       The default icon	name is	the application	name.

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

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

       -w number
	       This option specifies the width in pixels of  the  border  sur-
	       rounding	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".

       -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  sur-
	       rounding	the window.

	       This  appears  to be a legacy of	older X	releases.  It sets the
	       borderWidth resource of the shell widget, and may  provide  ad-
	       vice  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
	       VT102 window; see X(1).

	       The  normal  geometry specification can be suffixed with	@ fol-
	       lowed 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  re-
	       sources	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 correspond-
	       ing 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.   The  de-
	       fault  title is the command line	specified after	the -e option,
	       if any, otherwise the application name.

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

RESOURCES
       The program 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 to-
	       gether 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	termi-
		   nal 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	 char-
		   acter for the initial state of DECBKM

	       o   if  backarrowKeyIsErase  is	false,	xterm sets DECBKM to 2
		   (internal).	This ties together backarrowKey	and  the  con-
		   trol	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

       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  en-
	       tries  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 in-
	       volves 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  se-
	       lecting 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 re-
	       source 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  com-
	       piled-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, includ-
	       ing "panel" and "menu".	Those are typically set	via a  ".desk-
	       top"  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 over-
	       ridden 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, tcapFunction-
	       Keys, 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 re-
	       sources 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 minBuf-
	       Size 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".

       messages	(class Messages)
	       Specifies  whether write	access to the terminal is allowed ini-
	       tially.	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  unneces-
	       sary (and very large) fonts, e.g., in a locale having UTF-8 en-
	       coding.	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  transla-
	       tions at	startup.  The resource value is	a comma-separated list
	       of keywords, which may be abbreviated:  "fullscreen",  "scroll-
	       lock",  "shift-fonts"  or "wheel-mouse".	 Xterm also recognizes
	       "default", but omitting that will make the program unusable un-
	       less  you  provide  a  similar definition in your resource set-
	       tings.

       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  no-
	       tion  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.

	       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 ini-
	       tialization 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 intial screen size, e.g., via window	manager	inter-
	       action.

	       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 OS X systems, "true" otherwise.

       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".

       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  lim-
	       ited 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 se-
	       lecting 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  se-
	       lecting 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 accu-
	       rately.	 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 the	document 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  de-
	       scribed	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 environ-
	       ment variable should be generated for function keys instead  of
	       those  configured  using	sunKeyboard and	keyboardType.  The de-
	       fault is	"false", i.e., this feature is disabled.

	       The keyboardType	resource is the	preferred  mechanism  for  se-
	       lecting this mode.

       termName	(class TermName)
	       Specifies the terminal type name	to be set in the TERM environ-
	       ment 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 and the
	       characters  to which they may be	bound.	Allowable keywords in-
	       clude: brk, dsusp, eof, eol, eol2, erase, erase2, flush,	 intr,
	       kill,  lnext, quit, rprnt, start, status, stop, susp, swtch and
	       weras.  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	 back-
	       slash in	an X resource escapes the next character.

	       This  is	 very  useful for overriding the default terminal set-
	       tings without having to do an  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.

	       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".

       waitForMap (class WaitForMap)
	       Specifies whether or not	xterm should wait for the initial win-
	       dow 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
	       -geom.  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	iconi-
	       fied 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 de-
	       fault is	"false".

       zIconTitleFormat	(class ZIconTitleFormat)
	       Allow customization of the string used in  the  zIconBeep  fea-
	       ture.  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 pat-
       terns 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 applica-
	       tion icon windows.  Some	window managers	will allow you to  en-
	       ter  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 sup-
		      port),  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 over-
	       rides  both the alwaysBoldMode and the boldMode resources.  al-
	       waysBoldMode (class AlwaysBoldMode)

       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".

       allowPasteControls (class AllowPasteControls)
	       If true,	allow control characters such as BEL  and  CAN	to  be
	       pasted.	 Formatting  characters	 (tab, newline)	are always al-
	       lowed.  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 tog-
	       gling 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  configura-
	       tions,  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 (gen-
	       erated using the	X protocol SendEvent request) should be	inter-
	       preted  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	force-
	       fully 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  ca-
	       pabilities 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 sup-
		   ports.  This	is a constant, depending on  how  it  is  com-
		   piled,  typically  16.  It does not change if you alter re-
		   source 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 ti-
	       tle 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 se-
	       quences 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 con-
		   trol	 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  cor-
		   responding combinations of ESC-prefix and 8-bit characters.

	       The  default is "False".	 Xterm provides	a menu option for tog-
	       gling this resource.

       alternateScroll (class ScrollCond)
	       If "true", the scroll-back and scroll-forw  actions  send  cur-
	       sor-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  se-
	       quence.

       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 han-
	       dle 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 high-
	       lighted 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  se-
	       quences	even if	those modifiers	appear in the translations re-
	       source.	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  de-
	       fault 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-au-
	       tomatically 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 con-
	       trol sequence.  A "true"	value specifies	 backspace.   The  de-
	       fault  is "True".  Pressing the control key toggles this	behav-
	       ior.

       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 man-
	       ager 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	 over-
	       striking.  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  re-
	       sources.

       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 at-
	       tribute.

	       Note that xterm has one bold font which you may set explicitly.
	       Xterm attempts to derive	a bold font for	the other font	selec-
	       tions (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 pro-
	       vide 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  specifica-
	       tion 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 use-
	       ful 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 ap-
	       plication  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 char-
	       acters found within the string are not ignored; they  are  pro-
	       cessed 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 af-
	       ter parsing the control.

	       When enabled, this feature allows the user to exit from an  un-
	       terminated  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	clear-
	       ing 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  de-
	       fault 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.

       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  de-
	       faults  are, respectively, black, red3, green3, yellow3,	a cus-
	       tomizable 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 re-
	       spectively, gray30, red,	green, yellow,	a  customizable	 light
	       blue, magenta, cyan, and	white.

       color16 (class Color16)

       through

       color255	(class Color255)
	       These  specify the colors for the 256-color extension.  The de-
	       fault resource values are for colors 16 through 231 to  make  a
	       6x6x6  color  cube,  and	 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 in-
	       consistent 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 val-
	       ues, 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	"XtDe-
	       faultForeground".

	       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	"XtDe-
	       faultForeground".

	       See also	the veryBoldColors resource which allows combining un-
	       derline 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	"XtDe-
	       faultForeground".

	       See also	the veryBoldColors resource which allows combining at-
	       tributes	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.

       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 re-
	       verse and color.

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

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

	       See also	the veryBoldColors resource which allows combining un-
	       derline 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 un-
	       derlining.  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  de-
	       fault 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.	The default is
	       "false".

	       Xterm uses  two	variables  to  determine  whether  the	cursor
	       blinks.	One is set by this resource.  The other	is set by con-
	       trol sequences (private mode 12 and DECSCUSR).  Xterm tests the
	       XOR of the two variables.

       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 cy-
	       cle-time,  in  milliseconds.   The  same	timer is used for text
	       blinking.  The default is "600".

       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".

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

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

       decTerminalID (class DecTerminalID)
	       Specifies  the  emulation  level	 (100=VT100, 220=VT220,	etc.),
	       used to determine the type of response  to  a  DA  control  se-
	       quence.	  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	repre-
	       sented 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  lay-
	       out on the screen as the	original text.

       deleteIsDEL (class DeleteIsDEL)
	       Specifies  whether  the Delete key on the editing keypad	should
	       send DEL	(127) or the VT220-style Remove	 escape	 sequence.   A
	       "false" value enables the latter.  The default is "Maybe".

       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.

       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 de-
	       fault value is
	       20,21,SetXprop,SetSelection

	       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.

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

	       GetScreenSizeChars (19)
		    Report the size of the screen in characters	as numbers.

	       GetSelection
		    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.

	       GetWinTitle (21)
		    Report xterm window's title	as a string.

	       LowerWin	(6)
		    Lower  the	xterm window to	the bottom of the stacking or-
		    der.

	       MaximizeWin (9)
		    Maximize window (i.e., resize to screen size).

	       FullscreenWin (10)
		    Use	full screen (i.e., resize to screen size, without win-
		    dow	decorations).

	       MinimizeWin (2)
		    Iconify window.

	       PopTitle	(23)
		    Pop	title from internal stack.

	       PushTitle (22)
		    Push title to internal stack.

	       RaiseWin	(5)
		    Raise the xterm window to the front	of the stacking	order.

	       SetWinSizePixels	(4)
		    Resize the xterm window to given size in pixels.

	       SetXprop
		    Set	X property on top-level	window.

       dynamicColors (class DynamicColors)
	       Specifies  whether or not escape	sequences to change colors as-
	       signed 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 de-
	       fault is	"false".

       eightBitInput (class EightBitInput)
	       If "true", Meta characters (a  single-byte  character  combined
	       with  the  Meta	modifier key) input from the keyboard are pre-
	       sented as a single character, modified according	to the	eight-
	       BitMeta	resource.   If	"false", Meta characters are converted
	       into a two-character sequence with the  character  itself  pre-
	       ceded 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  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 de-
	       fines  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 Num-
	       Lock 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" dif-
	       fers 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	 char-
	       acter and ignores the eighth bit.

       eightBitMeta (class EightBitMeta)
	       This  controls  the way xterm modifies the eighth bit of	a sin-
	       gle-byte	key when the eightBitInput resource is set.   The  de-
	       fault 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  en-
		    coding.

	       true The	key is sent modified.

	       never
		    The	key is always sent unmodified.

	       Except for the never choice, xterm honors the terminfo capabil-
	       ities 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   SE-
	       LECT/PASTE)  for	 selections  in	normal (ISO-8859-1) mode.  The
	       default is an empty string, i.e., "", which does	 not  override
	       anything.

       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.

	       If  not	specified, or if there is no match for both normal and
	       bold fonts, xterm uses the 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	appli-
	       cation  requires	 this, e.g., in	CJK applications.  There is no
	       default value.

	       If the application uses double-wide  characters	and  this  re-
	       source  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  li-
	       brary if	support	for that library was compiled into xterm.  The
	       default is "14.0" On the	VT Fonts menu, this corresponds	to the
	       Default entry.

	       Although	the default is "14.0", 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.  For example, the "fixed"
	       font usually has	a pointsize of "8.0".  If you set faceSize  to
	       match  the size of the bitmap font, then	switching between bit-
	       map and TrueType	fonts via the font menu	will  give  comparable
	       sizes for the window.

	       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, correspond-
	       ing 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, correspond-
	       ing 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 de-
	       fault 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 nor-
		   mally  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 char-
	       acters, and draws them directly.	 The default is	"false".

       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.

       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 mod-
	       ified keys with the modifyOtherKeys resource.

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

	       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 com-
	       pares 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	VT102  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  de-
	       fault  foreground),  reverse  video  is	used.	The default is
	       "XtDefaultForeground".

       highlightColorMode (class HighlightColorMode)
	       Specifies whether xterm should use highlightTextColor and high-
	       lightColor  to override the reversed foreground/background col-
	       ors 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 re-
	       source 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
		  highlightColor

	       HFG
		  highlightTextColor

	       default	 true	 set	   set	     HFG/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	 high-
	       lightTextColor  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)
	       If  "false",  selecting with the	mouse highlights all positions
	       on the screen between the beginning of the  selection  and  the
	       current	position.   If "true", xterm highlights	only the posi-
	       tions 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 in-
	       ternal 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  de-
	       fault  background),  reverse  video  is	used.	The default is
	       "XtDefaultBackground".

       hpLowerleftBugCompat (class HpLowerleftBugCompat)
	       Specifies whether to work around	a bug in HP's xdb,  which  ig-
	       nores  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 XtCInputMethod)
	       Tells xterm which type of input method to use.  There is	no de-
	       fault 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  charac-
	       ters.  It is implemented	only for TrueType fonts.

       jumpScroll (class JumpScroll)
	       Specifies whether or not	jump scroll should be used.  This cor-
	       responds	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 keyboard rather than asking the clipboard for its
	       current	contents  when told to provide the selection.  The de-
	       fault is	"false".

       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".

       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.

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

       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 accord-
		   ing 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	subre-
	       sources	of  the	VT100 widget.  That is,	resource patterns such
	       as "*vt100.utf8Fonts.font" will be loaded,  and	(if  this  re-
	       source  is  enabled),  override the normal fonts.  If no	subre-
	       sources are found, the  normal  fonts  such  as	"*vt100.font",
	       etc.,  are used.	 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 lo-
	       cale 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".

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

       metaSendsEscape (class MetaSendsEscape)
	       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.  If "false", Meta	characters in-
	       put  from the keyboard are handled according to the eightBitIn-
	       put 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 val-
	       ues, and	allows up to mkSamplePass mismatches before  the  test
	       fails.	The  default (for the allowed number of	mismatches) is
	       256.

       mkSampleSize (class MkSampleSize)
	       With mkSamplePass, this specifies a startup test	used for  ini-
	       tializing wide character	width calculations.  The default (num-
	       ber of characters to check) is 1024.

       mkWidth (class MkWidth)
	       Specifies whether xterm should use a built-in  version  of  the
	       wide  character	width  calculation.  See also the cjkWidth re-
	       source 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

       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  es-
	       cape 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  es-
	       cape  sequence  returned	by a (numbered)	function-key.  The de-
	       fault is	"2".  The resource values are  similar	to  modifyCur-
	       sorKeys:

	       -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 re-
		    source.

       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-mod-
		    ifier  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 se-
	       quence for other	keys (such as "2") when	modified by  Control-,
	       Alt-  or	 Meta-modifiers.  This feature does not	apply to func-
	       tion keys and well-defined keys such  as	 ESC  or  the  control
	       keys.  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 con-
		    trol character cases, e.g.,	Control-Space to make a	NUL.

	       2    enables  this  feature  for	 keys including	the exceptions
		    listed.

       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	 asyn-
	       chronously.  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".

       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 re-
	       source.	 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  key-
	       boardType  to  legacy.	The  keyboardType resource is the pre-
	       ferred 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  de-
	       scribed in the SELECTION	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  a  "word"  as	 determined  by	the regular expression
		  which	follows	in the resource	value.

	       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	deter-
	       mines the maximum number	of clicks by  the  onXClicks  resource
	       values which are	set.

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

       preeditType (class XtCPreeditType)
	       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 (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 ac-
	       tual 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 (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 re-
	       source to the prefix of the filename (a timestamp will  be  ap-
	       pended 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 (PrintModeImmediate)
	       When the	print-immediate	action is invoked,  xterm  prints  the
	       screen  contents	directly to a file.  You can use the printMod-
	       eImmediate resource to tell it to use escape sequences  to  re-
	       construct  the video attributes and colors.  This uses the same
	       values as the printAttributes resource.	The default is "0".

       printModeOnXError (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  re-
	       source.	The default is "0".

       printOptsImmediate (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 be-
		   ing used.  In that case, only the alternate screen  is  se-
		   lectd.

	       o   If nonzero, the bits	of this	resource value (checked	in de-
		   scending 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 nor-
		      mal 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 (PrintOptsOnXError)
	       Specify	the  range of text which is printed to a file when the
	       print-on-error action is	invoked.  The resource value is	inter-
	       preted 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 ap-
	       plication switches the printer offline with a Media  Copy  com-
	       mand.  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
	       you move	the cursor off that line with a	line feed,  form  feed
	       or  vertical  tab  character, or	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 true,	allocate separate color	registers for each  sixel  de-
	       vice control string, e.g., for DECGCI.  If not true, color reg-
	       isters are allocated only once, when  the  terminal  is	reset.
	       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".

       regisScreenSize (class RegisScreenSize)
	       If xterm	is configured to support ReGIS graphics, this resource
	       tells xterm the maximum size (in	pixels)	for graphics.

	       Xterm accepts a special	resource  value	 "auto",  which	 tells
	       xterm to	use the	decTerminalID resource to set the maximum size
	       based on	the hardware terminal's	limits.	 Otherwise, xterm  ex-
	       pects the size to be given as heightxwidth, e.g., "800x1000".

	       The default resource value is "800x1000".

       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
		    startup  using  the	 normal	 (bitmap) font,	but enable the
		    "TrueType Fonts" menu entry	 to  allow  runtime  switching
		    to/from TrueType fonts.

		    If there is	no faceName resource set, then runtime switch-
		    ing	to TrueType fonts is disabled.	Xterm has  a  separate
		    compiled-in	 value for faceName for	the special case where
		    renderFont is "default".  That is normally "mono".

       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 be-
	       havior  in R4.  SouthWest (the default) specifies that the bot-
	       tom 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 XtCRetryInputMethod)
	       Tells xterm how many times to retry, in case  the  input-method
	       server  is  not responding.  This is a different	issue than un-
	       supported preedit type, etc.  You may encounter retries if your
	       X  configuration	 (and its libraries) are missing pieces.  Set-
	       ting 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  re-
		   verse  the  foreground and background colors.  Xterm's com-
		   mand-line options set resource values.  In particular,  the
		   X  Toolkit  sets the	reverseVideo resource when the -rv op-
		   tion	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  re-
		   source  values to reconstruct the command-line options, and
		   determine which of the colors is the	user's intended	 fore-
		   ground, etc.	 Their actual values are irrelevant to the re-
		   verse 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 reverseV-
		   ideo	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" fea-
		   ture), 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 "64".

       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 wid-
	       get 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  re-
	       gion.   This corresponds	to xterm's private mode	1011.  The de-
	       fault 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 automat-
	       ically 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  true,  graphics  scroll  up	one line at a time when	sixels
	       would be	written	past the bottom	line on	the window.   The  de-
	       fault is	"false".

       tekGeometry (class Geometry)
	       Specifies the preferred size and	position of the	Tektronix win-
	       dow.  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 pro-
	       cessing the ti termcap entry, i.e., the private modes 47,  1047
	       or  1049.  This is only in effect if titeInhibit	is "true", be-
	       cause 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)
	       Specifies  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.  If
	       set, xterm also ignores the escape sequence to  switch  to  the
	       alternate  screen.  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.  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	 (overrides  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 underlin-
	       ing  when color is being	used for the underline attribute.  The
	       default is "true".

       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 turn-
		  ing 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  re-
		  source  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  pat-
	       terns  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 "de-
	       fault".

	       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,	allow-
		      ing 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,  ac-
		      cording 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  SE-
	       LECT/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  se-
	       quence.	 Normally this control sequence	follows	the VT220 con-
	       vention,	which encodes the string in ISO-8859-1 and allows  for
	       an 8-bit	string terminator.  If xterm is	started	in a UTF-8 lo-
	       cale, 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  allow	 UTF-8
	       encoded	title strings.	That cancels the translation to	UTF-8,
	       allowing	UTF-8 strings to be displayed as is.

	       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 "Ti-
	       tle Modes" in the control sequences document), to set an	equiv-
	       alent flag.  The	titleModes resource sets the same value, which
	       overrides this resource.

	       The default is "false".

       veryBoldColors (class VeryBoldColors)
	       Specifies whether to combine video attributes with colors spec-
	       ified 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 display-
	       ing 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 char-
	       acter  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 dou-
	       ble-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 de-
	       fault value is "*".  This matches every font, the X library au-
	       tomatically 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 sta-
	       tus report.  The	possibilities are "none", which	sends no  ter-
	       minating	 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 de-
	       fault is	"large".

       width (class Width)
	       Specifies the width of the Tektronix window in pixels.

   Menu	Resources
       The resources that may be specified for the various menus are described
       in  the	documentation  for the Athena SimpleMenu widget.  The name and
       classes of the entries in each of the  menus  are  listed  below.   Re-

   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	VT102 window is	created, xterm allows you to select  text  and
       copy it within the same or other	windows.

   Selection
       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.	 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  re-
       leasing	the  button.  The selected text	is highlighted and is saved in
       the global cut buffer and made the PRIMARY selection when the button is
       released.  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/but-
       ton 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
       PRIMARY	selection, if any, otherwise from the cut buffer, inserting it
       as keyboard input.

       Pointer button three (usually right)  extends  the  current  selection.
       (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  com-
       mand  to	 the shell, for	example, or take output	from a program and in-
       sert 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 de-
       limited 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 ac-
       tually 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 ad-
       jacent 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 VT102	window,	the Tektronix window does not allow the	 copy-
       ing  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 server.

   Primary
       When configured to use the primary selection, (the default)  xterm  can
       provide	the  selection data in ways which help to retain character en-
       coding information as it	is pasted.

       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 (see resource selectToClipboard),
       the problem with	persistence  of	 ownership  is	bypassed.   Otherwise,
       there  is  no difference	regarding the data which can be	passed via se-
       lection.

       The PRIMARY token is a standard X feature, documented in	the ICCCM (In-
       ter-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.

       However,	 many applications use CLIPBOARD in imitation of other window-
       ing 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.

   Selection Targets
       The different types of data which are passed depend on what the receiv-
       ing 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-charac-
		   ter support,	it both	accepts	and provides this type.

	      TEXT the	text is	in the encoding	which corresponds to your cur-
		   rent	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  config-
       ured 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  in-
       sert  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  spe-
       cific  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 ex-
       pressed in several ways,	e.g.,

	      UTF8_STRING,I18N,STRING
	      utf8,i18n,string
	      u,i,s

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	VT102 and Tektronix windows.  There are	several	sections:

       Commands	for managing X events:

	      Toolbar
		     Clicking on the "Toolbar" menu entry hides	the toolbar if
		     it	is visible, and	shows it if it is not.

	      Secure Keyboard (securekbd)
		     The Secure	Keyboard mode is helpful when typing in	 pass-
		     words or other sensitive data in an unsecure environment;
		     see SECURITY below	(but read the limitations carefully).

	      Allow SendEvents (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 al-
		     lowSendEvents resource.

	      Redraw Window (redraw)
		     Forces  the X display to repaint; useful in some environ-
		     ments.

       Commands	for capturing output:

	      Log to File (logging)
		     Captures text sent	to the screen in a logfile, as in  the
		     -l	logging	option.

	      Print-All	Immediately
		     Invokes  the  print-immediate action, sending the text of
		     the current window	directly to a file,  as	 specified  by
		     the  printFileImmediate, printModeImmediate and printOpt-
		     sImmediate	resources.

	      Print-All	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	 printFileXError,  printModeXError and
		     printOptsXError resources.

	      Print Window (print)
		     Sends the text of the current window to the program given
		     in	the printerCommand resource.

	      Redirect to Printer (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	(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 equiva-
		     lent 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  Me-
		     dia  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 (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, dou-
		     ble  underline,  faint, strikeout,	reverse; blink is ren-
		     dered as white-on-red.  The font is  whatever  your  ren-
		     derer 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 (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 the	document Xterm Control
		     Sequences).  This corresponds to the eightBitControl  re-
		     source.

	      Backarrow	Key (BS/DEL) (backarrow	key)
		     Modifies  the  behavior  of  the backarrow	key, making it
		     transmit either a backspace (8) or	delete	(127)  charac-
		     ter.  This	corresponds to the backarrowKey	resource.

	      Alt/NumLock Modifiers (num-lock)
		     Controls the treatment of Alt- and	NumLock-key modifiers.
		     This corresponds to the numLock resource.

	      Meta Sends Escape	(meta-esc)
		     Controls whether Meta keys	are converted into a two-char-
		     acter sequence with the character itself preceded by ESC.
		     This corresponds to the metaSendsEscape resource.

	      Delete is	DEL (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	(oldFunctionKeys)

	      HP Function-Keys (hpFunctionKeys)

	      SCO Function-Keys	(scoFunctionKeys)

	      Sun Function-Keys	(sunFunctionKeys)

	      VT220 Keyboard (sunKeyboard)
		     These act as a radio-button, selecting one	style for  the
		     keyboard  layout.	 It  corresponds  to more than one re-
		     source setting:  sunKeyboard,  sunFunctionKeys,  scoFunc-
		     tionKeys and hpFunctionKeys.

       Commands	for process signalling:

	      Send STOP	Signal (suspend)

	      Send CONT	Signal (continue)

	      Send INT Signal (interrupt)

	      Send HUP Signal (hangup)

	      Send TERM	Signal (terminate)

	      Send KILL	Signal (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 ac-
		     cidentally	typed CTRL-Z, suspending the process.

	      Quit (quit)
		     Stop  processing X	events except to support the -hold op-
		     tion, and then send a SIGHUP signal to the	process	 group
		     of	the process running under xterm	(usually the shell).

   VT Options
       The  vtMenu sets	various	modes in the VT102 emulation, and is popped up
       when the	"control" key and pointer button two are pressed in the	 VT102
       window.

       VT102/VT220 Modes:

	      Enable Scrollbar (scrollbar)
		     Enable  (or  disable) the scrollbar.  This	corresponds to
		     the -sb option and	the scrollBar resource.

	      Enable Jump Scroll (jumpscroll)
		     Enable (or	disable) jump scrolling.  This corresponds  to
		     the -j option and the jumpScroll resource.

	      Enable Reverse Video (reversevideo)
		     Enable  (or  disable) reverse-video.  This	corresponds to
		     the -rv option and	the reverseVideo resource.

	      Enable Auto Wraparound (autowrap)
		     Enable (or	disable) auto-wraparound.  This	corresponds to
		     the -aw option and	the autoWrap resource.

	      Enable Reverse Wraparound	(reversewrap)
		     Enable (or	disable) reverse wraparound.  This corresponds
		     to	the -rw	option and the reverseWrap resource.

	      Enable Auto Linefeed (autolinefeed)
		     Enable (or	disable) auto-linefeed.	 This is the VT102 NEL
		     function,	which  causes  the emulator to emit a linefeed
		     after each	carriage return.  There	 is  no	 corresponding
		     command-line option or resource setting.

	      Enable Application Cursor	Keys (appcursor)
		     Enable (or	disable) application cursor keys.  This	corre-
		     sponds to the appcursorDefault  resource.	 There	is  no
		     corresponding command-line	option.

	      Enable Application Keypad	(appkeypad)
		     Enable (or	disable) application keypad keys.  This	corre-
		     sponds to the appkeypadDefault  resource.	 There	is  no
		     corresponding command-line	option.

	      Scroll to	Bottom on Key Press (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 (scrollttyoutput)
		     Enable (or	 disable)  scrolling  to  the  bottom  of  the
		     scrolling	region on output to the	terminal.  This	corre-
		     sponds to the -si	option	and  the  scrollTtyOutput  re-
		     source.

	      Allow 80/132 Column Switching (allow132)
		     Enable (or	disable) switching between 80 and 132 columns.
		     This corresponds to the -132  option  and	the  c132  re-
		     source.

	      Keep Selection (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,	it can provide the corresponding text to other
		     clients via cut/paste.  This corresponds to  the  keepSe-
		     lection resource.	There is no corresponding command-line
		     option.

	      Select to	Clipboard (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.

	      Enable Visual Bell (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 (bellIsUrgent)
		     Enable (or	disable) Urgency window	manager	hint when Con-
		     trol-G is received.  This corresponds to the bellIsUrgent
		     resource.

	      Enable Pop on Bell (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 (cursorblink)
		     Enable (or	disable) the  blinking-cursor  feature.	  This
		     corresponds  to  the  -bc	option and the cursorBlink re-
		     source.  There is also an escape sequence (see the	 docu-
		     ment  Xterm  Control  Sequences).	The menu entry and the
		     escape sequence states are	XOR'd: if  both	 are  enabled,
		     the  cursor  will	not blink, if only one is enabled, the
		     cursor will blink.

	      Enable Alternate Screen Switching	(titeInhibit)
		     Enable (or	disable) switching between the normal and  al-
		     ternate screens.  This corresponds	to the titeInhibit re-
		     source.  There is no corresponding	command-line option.

	      Enable Active Icon (activeicon)
		     Enable (or	disable) the active-icon feature.  This	corre-
		     sponds to the -ai option and the activeIcon resource.

	      Sixel Scrolling (sixelScrolling)
		     When  enabled,  sixel graphics are	positioned at the cur-
		     rent 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  re-
		     turning  to  text	mode (this is the default).  When dis-
		     abled, sixel graphics are positioned at the upper left of
		     the screen, are cropped to	fit the	screen,	and do not af-
		     fect the text cursor location.  This corresponds  to  the
		     sixelScrolling  resource.	There is no corresponding com-
		     mand-line option.

	      Private Color Registers (privateColorRegisters)
		     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 True-
		     Color hardware.  This corresponds to the privateColorReg-
		     isters  resource.	There is no corresponding command-line
		     option.

       VT102/VT220 Commands:

	      Do Soft Reset (softreset)
		     Reset scroll regions.  This can be	convenient  when  some
		     program  has left the scroll regions set incorrectly (of-
		     ten a problem when	using VMS or  TOPS-20).	  This	corre-
		     sponds to the VT220 DECSTR	control	sequence.

	      Do Full Reset (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  op-
		     tions.   This  corresponds	 to  the VT102 RIS control se-
		     quence, with a few	 obvious  differences.	 For  example,
		     your  session  is	not disconnected as a real VT102 would
		     do.

	      Reset and	Clear Saved Lines (clearsavedlines)
		     Perform a full reset, and also clear the saved lines.

       Commands	for setting the	current	screen:

	      Show Tek Window (tekshow)
		     When enabled, pops	the Tektronix 4014 window up (makes it
		     visible).	 When  disabled, hides the Tektronix 4014 win-
		     dow.

	      Switch to	Tek Mode (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 (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 (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  fontMenu  pops  up	when when the "control"	key and	pointer	button
       three are pressed in a window.  It sets the font	used in	the VT102 win-
       dow, 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  alterna-
       tives:

	      Default (fontdefault)
		     Set  the  font  to	 the  default, i.e., that given	by the
		     *VT100.font resource.

	      Unreadable (font1)
		     Set the font to that given	by the *VT100.font1 resource.

	      Tiny (font2)
		     Set the font to that given	by the *VT100.font2 resource.

	      Small (font3)
		     Set the font to that given	by the *VT100.font3 resource.

	      Medium (font4)
		     Set the font to that given	by the *VT100.font4 resource.

	      Large (font5)
		     Set the font to that given	by the *VT100.font5 resource.

	      Huge (font6)
		     Set the font to that given	by the *VT100.font6 resource.

	      Escape Sequence
		     This allows you to	set the	font last specified by the Set
		     Font  escape sequence (see	the document Xterm Control Se-
		     quences).

	      Selection	(fontsel)
		     This allows you to	set the	font specified the current se-
		     lection  as  a  font  name	 (if  the PRIMARY selection is
		     owned).

       The second section allows you to	modify the way it is displayed:

	      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 (font-linedrawing)
		     When set, tells xterm to draw its own line-drawing	 char-
		     acters.   Otherwise  it  relies  on  the  font containing
		     these.  Compare to	the forceBoxChars resource.

	      Packed Font (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 (font-doublesize)
		     When set, xterm may ask the font server to	produce	scaled
		     versions of the normal font, for VT102 double-size	 char-
		     acters.

       The third section allows	you to modify the way it is specified:

	      TrueType Fonts (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 (utf8-mode)
		     This  controls  whether  xterm uses UTF-8 encoding	of in-
		     put/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  re-
		     source.

	      UTF-8 Fonts (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.

	      UTF-8 Titles (utf8-titles)
		     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 oper-
	      ations  which  can  be controlled	by writing escape sequences to
	      the terminal.  These are disabled	if the SendEvents  feature  is
	      enabled:

	      Allow Color Ops (allow-font-ops)
		     This  corresponds	to the allowColorOps resource.	Enable
		     or	disable	control	sequences that set/query the colors.

	      Allow Font Ops (allow-font-ops)
		     This corresponds to the allowFontOps resource.  Enable or
		     disable control sequences that set/query the font.

	      Allow Tcap Ops (allow-tcap-ops)
		     Enable or disable control sequences that query the	termi-
		     nal's notion of its function-key strings, as  termcap  or
		     terminfo  capabilities.   This corresponds	to the allowT-
		     capOps resource.

	      Allow Title Ops (allow-title-ops)
		     Enable or disable control sequences that modify the  win-
		     dow title or icon name.  This corresponds to the allowTi-
		     tleOps resource.

	      Allow Window Ops (allow-window-ops)
		     Enable or disable extended	window control	sequences  (as
		     used  in dtterm).	This corresponds to the	allowWindowOps
		     resource.

   TEK Options
       The 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 (tektextlarge)

	      #2 Size Characters (tektext2)

	      #3 Size Characters (tektext3)

	      Small Characters (tektextsmall)

       Commands:

	      PAGE (tekpage)
		     Clear the Tektronix window.

	      RESET (tekreset)

	      COPY (tekcopy)

       Windows:

	      Show VT Window (vtshow)

	      Switch to	VT Mode	(vtmode)

	      Hide Tek Window (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	 secu-
	   rity	 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 ev-
	   erything 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 applica-
	   tions 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, in-
	   cluding 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 bet-
	   ter authorization mechanism than is provided	by X.

       Subject to all of these caveats,	a simple mechanism exists for protect-
       ing 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  di-
       rected  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  key-
	   strokes.

       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	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  dis-
       plays  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 win-
       dow becomes iconified (or otherwise unmapped), or if you	start up a re-
       parenting  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 fore-
       ground 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.  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.
       The value is arbitrary, although	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	bytes 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,

	      For example, the string  "33:48,37:48,45-47:48,38:48"  indicates

	      and ampersand characters should be treated the same way as char-
	      acters  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	unpre-
       dictable	behavior.

   Actions
       The following actions are provided for use within the vt100 or  tek4014
       translations resources:

       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-send-events(on/off/toggle)
	       This  action  sets,  unsets  or toggles the allowSendEvents re-
	       source 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() (see below) 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
	       beep().	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  fea-
	       ture  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 echo-
	       ing the event's position	(i.e., character line and  column)  in
	       the following format:

		       ^X ESC G	<line+"	"> <col+" ">

       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 se-
	       lection 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  re-
		    gion, 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  sec-
	       ond  parameter  specifies the method for	copying	the data as in
	       the onClicks 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  charac-
	       ter  or	string associated with the key that was	pressed.  Only
	       single-byte values are treated specially.  The exact action de-
	       pends  on  the  value  of  the altSendsEscape and the metaSend-
	       sEscape 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  pa-
	       rameter,	format gives the template for the data as in exec-for-
	       matted.	The second parameter specifies the method for  copying
	       the data	as in the onClicks resource.

       insert-selection(sourcename [, ...])
	       This  action  inserts the string	found in the selection or cut-
	       buffer indicated	by sourcename.	Sources	are checked in the or-
	       der  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_BUF-
	       FER7.

       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 (case is signifi-
	       cant).  The name	None restores the original translation table.

       larger-vt-font()
	       Set the font to the next	larger one, based on the  font	dimen-
	       sions.  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 se-
	       lect-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  wideBold-
	       Font.

       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 over-
	       ride  resource  settings.  The parameter	values are matched ig-
	       noring 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 new-
		    line)  to  the  screen  width  (i.e.,  printerNewLine   is
		    ``true'').

	       noAttrs
		    the	 page  is  printed  without attributes (i.e., printAt-
		    tributes 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 printerCom-
	       mand 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	printFileXError, printModeXError and printOpt-
	       sXError 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 cur-
	       sor 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  re-
	       draw 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	 visi-
	       ble.

	       The  count argument indicates the number	of units (which	may be
	       page, halfpage, pixel, or line) by which	to scroll.

	       An adjustment can be specified for these	values by appending  a
	       "+" or "-" sign followed	by a number, e.g., page-2 to specify 2
	       lines less than a page.

	       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 described  in  the
	       section named 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 allowScrol-
	       lLock resource.

       select-cursor-end(destname [, ...])
	       This action is similar to select-end except that	it  should  be
	       used with select-cursor-start.

       select-cursor-extend()
	       This  action  is	similar	to select-extend except	that it	should
	       be used with select-cursor-start.

       select-cursor-start()
	       This action is similar to select-start except  that  it	begins
	       the selection at	the current text cursor	position.

       select-end(destname [, ...])
	       This  action  puts  the currently selected text into all	of the
	       selections or cutbuffers	specified by destname.	It also	 sends
	       a  mouse	 position  and updates the internal selection state to
	       reflect the end of the selection	process.

       select-extend()
	       This action tracks the pointer and extends the  selection.   It
	       should only be bound to Motion events.

       select-set()
	       This  action stores text	that corresponds to the	current	selec-
	       tion, without affecting the selection mode.

       select-start()
	       This action begins text selection at the	current	pointer	 loca-
	       tion.  See the section on POINTER USAGE for information on mak-
	       ing selections.

       send-signal(signame)
	       This action sends the signal named by signame to	the xterm sub-
	       process	(the  shell  or	 program specified with	the -e command
	       line option).  It is also invoked by the	suspend, continue, in-
	       terrupt,	 hangup, terminate, and	kill entries in	mainMenu.  Al-
	       lowable signal names are	(case is not  significant):  tstp  (if
	       supported  by  the  operating  system), suspend (same as	tstp),
	       cont (if	supported by the operating system),  int,  hup,	 term,
	       quit, alrm, alarm (same as alrm)	and kill.

	       This action sets	the font or fonts currently being used in  the
	       VT102  window.	The  first argument is a single	character that
	       specifies the font to be	used:

	       d or D indicate the default font	(the font initially used  when
		      xterm was	started),

	       1  through  6 indicate the fonts	specified by the font1 through
		      font6 resources,

	       e or E indicate the normal and bold fonts that  have  been  set
		      through  escape  codes  (or  specified as	the second and
		      third action arguments, respectively), and

	       s or S indicate the font	selection (as made by programs such as
		      xfontsel(1)) indicated by	the second action argument.

	       If  xterm  is  configured  to support wide characters, an addi-
	       tional two optional parameters are recognized for the  e	 argu-
	       ment: wide font and wide	bold font.

       smaller-vt-font()

	       sions.  See also	set-vt-font().

       soft-reset()
	       This action resets the scrolling	region.	 It  is	 also  invoked
	       from the	softreset entry	in vtMenu.  The	effect is identical to
	       a soft reset (DECSTR) control sequence.

       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.

       start-extend()
	       This  action  is	similar	to select-start	except that the	selec-
	       tion is extended	to the current pointer location.

       start-cursor-extend()
	       This action is similar to select-extend except that the	selec-
	       tion is extended	to the current text cursor position.

       string(string)
	       This action inserts the specified text string as	if it had been
	       typed.  Quotation is necessary if the  string  contains	white-
	       space  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 cur-
	       rent window contents to a file in the current directory	begin-
	       ning  with  the name COPY.  It is also invoked from the tekcopy
	       entry in	tekMenu.

       tek-page()
	       This action clears the Tektronix	window.	 It is also invoked by
	       the tekpage entry in tekMenu.

       tek-reset()
	       This action resets the Tektronix	window.	 It is also invoked by
	       the tekreset entry in tekMenu.

       vi-button()
	       Handles a button	event (other than press	and release) by	 echo-
	       ing 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.

				 <Btn5Down>:scroll-forw(5,line,m)     \n\
				    <BtnUp>:select-end(SELECT, CUT_BUFFER0) \n\
				  <BtnDown>:ignore()

       The default bindings in the Tektronix window are	analogous but less ex-
       tensive.	 These are for the tek4014 widget:

			    ~Meta<KeyPress>: insert-seven-bit()	\n\
			     Meta<KeyPress>: insert-eight-bit()	\n\
			   !Ctrl <Btn1Down>: popup-menu(mainMenu) \n\
		      !Lock Ctrl <Btn1Down>: popup-menu(mainMenu) \n\
	    !Lock Ctrl @Num_Lock <Btn1Down>: popup-menu(mainMenu) \n\
		 !Ctrl @Num_Lock <Btn1Down>: popup-menu(mainMenu) \n\
			   !Ctrl <Btn2Down>: popup-menu(tekMenu) \n\
		      !Lock Ctrl <Btn2Down>: popup-menu(tekMenu) \n\
	    !Lock Ctrl @Num_Lock <Btn2Down>: popup-menu(tekMenu) \n\
		 !Ctrl @Num_Lock <Btn2Down>: popup-menu(tekMenu) \n\
		      Shift ~Meta<Btn1Down>: gin-press(L) \n\
			    ~Meta<Btn1Down>: gin-press(l) \n\
		      Shift ~Meta<Btn2Down>: gin-press(M) \n\
			    ~Meta<Btn2Down>: gin-press(m) \n\
		      Shift ~Meta<Btn3Down>: gin-press(R) \n\
			    ~Meta<Btn3Down>: gin-press(r)

       Here is an example which	uses shifted select/paste to copy to the clip-
       board,  and  unshifted select/paste for the primary selection.  In each
       case, a (different) cut buffer is also a	target or source  of  the  se-
       lect/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 se-
       lection,	it highlights it.  When	it loses the selection,	it removes the
       corresponding  highlight.  But you can still paste from the correspond-
       ing 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;  the class name provides a more-specific
       match than the widget name.  A leading "*" is used because  the	widget
       hierarchy above the vt100 widget	depends	on whether the toolbar support
       is compiled into	xterm.

       Below is	shown a	sample of 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") string(0x0d) \n\
		   <Key>F18:	   string("step") string(0x0d) \n\
		   <Key>F19:	   string("continue") string(0x0d) \n\
		   <Key>F20:	   string("print ") 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  re-
       sources	are  distinct, and match different patterns, e.g., the differ-
       ences 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 "ac-
       tions"  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 con-
	   text	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 men-
	   tion	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 ex-
	   isting  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	 func-
	   tions  such as tab and backspace) do	not include the	escape charac-
	   ter.

       With all	of that	in mind, the standard refers  to  these	 sequences  of
       characters as "control sequences".

       The  Xterm Control Sequences document 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 Tek-
       tronix terminals, or from more widely used standards such as ISO-6429.

       A few examples of usage are given in this section.

   Window Titles
       Some scripts use	echo with options -e and -n to tell the	shell  to  in-
       terpret	the  string  "\e"  as  the  escape character and to suppress a
       trailing	newline	on output.  Those are not portable,  not  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.

   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" se-
	   quences such	as the control sequence	for  cursor-up	when  pressing
	   the up-arrow, and

       o   application mode, which uses	a different control sequence that can-
	   not 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	 defi-
       nitions of special keys are only	correct	for this keypad	mode.  For ex-
       ample, some shells (unlike ksh(1), which	appears	to be hard-coded,  not
       even  using  termcap)  allow their users	to customize key-bindings, as-
       signing 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	stati-
	   cally enumerate the possible	bindings for given values of $TERM.

       o   zsh(1)  provides  an	 analogous feature, but	it accepts runtime ex-
	   pressions, 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 ter-
	   minal  uses normal or application mode initially.  Here is an exam-
	   ple:

	       [[ "$terminfo[kcuu1]" ==	"^[O"* ]] && \
	       bindkey -M viins	"${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 stan-
       dard, 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 con-
	   vert	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 can-
       not be easily moved between different user environments.

ENVIRONMENT
       Xterm sets several environment variables:

       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	termi-
	    nal	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 necessar-
	    ily	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  At-
	    tributes (DA) control sequence (see	Xterm Control Sequences).

       Depending  on your system configuration,	xterm may also set the follow-
       ing:

       COLUMNS
	    the	width of the xterm in characters (cf: "stty columns").

       HOME when xterm is configured to	update utmp.

       LINES
	    the	height of the xterm in characters (cf: "stty rows").

       LOGNAME
	    when xterm is configured to	update utmp.

       SHELL
	    when xterm is configured 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.

       TERMINFO
	    may	be defined to a	nonstandard location in	the configure script.

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.

       /etc/utmp
	    the	system logfile,	which records user logins.

       /etc/wtmp
	    the	system logfile,	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 be-
       low, with a brief explanation.

       1    is	used  for  miscellaneous errors, usually accompanied by	a spe-

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.
