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
       aspect ratio that will fit in the window.  This box is located  in  the
       upper left area of the window.

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

		   xterm -z

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

       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
       options.	 A few of these	are marked, telling the	X  Toolkit  to	ignore
       them (-help, -version, -class, -e, and -into).  After the X Toolkit has
       parsed the command-line parameters, it removes those which it  handles,
       leaving the specially-marked parameters for xterm to handle.

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

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

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

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

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

       o   In a	few cases, the X Toolkit combines its standard options in ways
	   which  do  not  work	 well with xterm.  This	happens	with the color
	   (-fg, -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
	   before, xterm verifies if this is a valid shell.

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

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

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

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

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

       -ah     This option indicates that xterm	should	always	highlight  the
	       text cursor.  By	default, xterm will display a hollow text 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
	       allowed,	 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
	       sequences.  This	is the same as the vt100 resource colorMode.

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

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

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

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

	       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
	       resource	to "true".

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

       -hm     Tells xterm to use  highlightTextColor  and  highlightColor  to
	       override	 the reversed foreground/background colors in a	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
	       destroy	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
	       destroy 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
	       allowSendEvents resource	is enabled.

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

       +itc    Set the vt100 resource colorITMode to "true", enabling the 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
	       behind.	 Its  use is strongly recommended since	it makes xterm
	       much faster when	scanning through large amounts of  text.   The
	       VT100 escape sequences for enabling and disabling smooth	scroll
	       as well as the "VT Options" menu	can be used to turn this  fea-
	       ture on or off.

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

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

       -l      Turn logging on.	 Normally logging is  not  supported,  due  to
	       security	 concerns.   Some  versions  of	xterm may have logging
	       enabled.	 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
	       login  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
	       ignored,	the result of ~/.profile might interfere with that.

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

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

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

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

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

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

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

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

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

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

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

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

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

       +mk_width
	       Reset the mkWidth resource.

       -ms color
	       This option specifies the color to be used for the pointer 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
	       reportColors 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
	       attribute as color.

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

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

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

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

       +s      This option indicates that xterm	should scroll synchronously.

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

       +samename
	       Always send title and icon name change requests.

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

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

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

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

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

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

       -sh number
	       scale  line-height values by the	given number.  See the 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
	       Options"	menu.

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

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

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

       -sl number
	       This option specifies the number	of lines  to  save  that  have
	       been  scrolled  off the top of the screen.  This	corresponds to
	       the saveLines resource.	The default is "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
	       order 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
	       sequence.  Valid	values	include	 vt52,	vt100,	vt101,	vt102,
	       vt220,  and  vt240  (the	 "vt"  is  optional).	The default is
	       "vt420".	 The term_id argument specifies	 the  terminal	ID  to
	       use.  (This is the same as the decTerminalID resource).

       -tm string
	       This  option  specifies	a  series of terminal setting keywords
	       followed	by the characters that should be bound to those	 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
	       resource	as a side-effect, but  the  UTF-8  mode	 set  by  this
	       option  prevents	 it  from  being turned	off.  If you must turn
	       UTF-8 encoding on and off, use the -wc  option  or  the	corre-
	       sponding	wideChars resource, rather than	the -u8	option.

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

       +u8     This option resets the utf8 resource.

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

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

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

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

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

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

       -ut     This option indicates that xterm	should not write a record into
	       the 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
	       titles.	 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
	       option  contains	 a "/" character, that delimits	the characters
	       used for	the pseudo-terminal name  from	the  file  descriptor.
	       Otherwise,  exactly two characters are used from	the option for
	       the pseudo-terminal name, the remainder is the file descriptor.
	       Examples	 (the  first  two  are equivalent since	the descriptor
	       follows the last	"/"):

		   -S123/45
		   -Sab34

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

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

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

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

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

       -n string
	       This option specifies the icon name for xterm's windows.	 It is
	       shorthand  for  specifying the "*iconName" resource.  Note that
	       this is not the same as the toolkit option -name	 (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
	       advice to your window manager to	set the	thickness of the  win-
	       dow  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
	       resources are to	be obtained,  rather  than  the	 default  exe-
	       cutable	file name.  Name should	not contain "."	or "*" charac-
	       ters.

       -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
	       default	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
	       together	by setting the DECBKM state according to  whether  the
	       initial	erase  character  is  a	 backspace (8) or delete (127)
	       character.  A "false" value disables this feature.  The default
	       is "False".

	       Here are	tables showing how the initial settings	for

	       o   backarrowKeyIsErase (BKIE),

	       o   backarrowKey	(BK), and

	       o   ptyInitialErase (PIE), along	with the

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

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

	       o   xterm's internal value is ^H

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

	       o   the ttyModes	resource may override erase

	       o   if  ptyInitialErase is false, xterm will look in the	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
	       entries	that send a signal, e.g., HUP or KILL.	You may	scroll
	       back, select text, etc.,	to perform most	graphical  operations.
	       Resizing	 the  display  will  lose  data,  however,  since this
	       involves	interaction with the shell which is no longer running.

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

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

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

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

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

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

       maxBufSize (class MaxBufSize)
	       Specify the maximum size	of the input buffer.  The  default  is
	       "32768".	  You cannot set this to a value less than the 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
	       encoding.  The default is "C" (POSIX).

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

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

       omitTranslation (class OmitTranslation)
	       Selectively omit	one or more parts of xterm's default  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
	       unless  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
	       notion  of  the	screen	size, and ptySttySize which resets the
	       screen size after other terminal	 initialization	 is  complete.
	       The default is "true".

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

	       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
	       selecting this mode.

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

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

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

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

	       See also	the keyboardType resource.

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

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

       termName	(class TermName)
	       Specifies the terminal type name	to be set in the TERM 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
	       include:	 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 lit-
	       eral backslash 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
	       default 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
	       enter keystrokes	into the active	icon window.  The  default  is
	       "default".

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

	       false (0)
		      No active	icon is	shown.

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

	       default (2)
		      Xterm  checks  at	startup, and shows an active icon only
		      for window managers which	it can identify	and which  are
		      known to support the feature.  These are fvwm (full 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.
	       alwaysBoldMode (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
	       allowed.	  Other	 C0  control  characters are suppressed	unless
	       this resource is	enabled.  The exact set	of control  characters
	       (C0  and	 C1)  depends  upon whether UTF-8 encoding is used, as
	       well as the allowC1Printable resource.  The default is "false".

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

	       When this feature is enabled, xterm will	sense the state	of the
	       Scroll Lock key each time  it  acquires	focus.	 Pressing  the
	       Scroll Lock key toggles xterm's internal	state, as well as 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
	       capabilities should be allowed.	The default is "true".

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

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

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

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

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

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

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

	       o   If  "true",	Alt  characters	(a character combined with the
		   modifier associated with left/right Alt-keys) are converted
		   into	 a  two-character  sequence  with the character	itself
		   preceded by ESC.  This applies as well to function key 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
	       sequence.

       alwaysBoldMode (class AlwaysBoldMode)
	       Specifies whether xterm should check if	the  normal  and  bold
	       fonts  are distinct before deciding whether to use overstriking
	       to simulate bold	fonts.	If this	resource is true,  xterm  does
	       not make	the check for distinct fonts when deciding how to 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
	       sequences even if those modifiers appear	 in  the  translations
	       resource.   Normally  xterm  checks if Alt or Meta is used in a
	       translation that	would conflict with  function  key  modifiers,
	       and  will  ignore  these	 modifiers  in that special case.  The
	       default is "false".

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

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

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

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

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

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

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

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

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

       bellIsUrgent (class BellIsUrgent)
	       Specifies whether to set	the Urgency hint for the  window  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
	       resources.

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

	       Note that xterm has one bold font which you may set explicitly.
	       Xterm  attempts to derive a bold	font for the other font	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
	       application  control string without completing it.  Set this to
	       "true" if xterm appears to freeze when connecting.  The default
	       is "false".

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

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

	       Each should end with a string-terminator	(a  special  character
	       which  cannot appear in these strings).	Ordinary control 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
	       after parsing the control.

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

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

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

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

       cdXtraScroll (class CdXtraScroll)
	       Specifies whether xterm should scroll to	a new page when	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
	       default for this	resource is "false".

       charClass (class	CharClass)
	       Specifies  comma-separated lists	of character class bindings of
	       the form	[low-]high:value.  These are used in determining which
	       sets  of	 characters  should be treated the same	when doing cut
	       and paste.  See the CHARACTER CLASSES section.

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

       color0 (class Color0)

       color1 (class Color1)

       color2 (class Color2)

       color3 (class Color3)

       color4 (class Color4)

       color5 (class Color5)

       color6 (class Color6)

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

       color8 (class Color8)

       color9 (class Color9)

       color10 (class Color10)

       color11 (class Color11)

       color12 (class Color12)

       color13 (class Color13)

       color14 (class Color14)

       color15 (class Color15)
	       These specify the colors	for the	ISO-6429 extension if the bold
	       attribute  is  also  enabled.   The default resource values are
	       respectively, 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
	       default 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
	       inconsistent behavior  if  only	part  of  the  resources  were
	       allowed,	 determining  the exact	cutoff is difficult, and the X
	       libraries tend to crash if the number of	resources exceeds  the
	       limit.	The  color  palette  is	 still initialized to the same
	       default values, and can be modified via control sequences.

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

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

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

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

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

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

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

	       Note that:

	       o   Setting  colorMode  off  disables  all  colors,   including
		   italic.

	       o   The italicULMode resource overrides colorITMode.

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

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

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

       colorRVMode (class ColorAttrMode)
	       Specifies whether characters with the reverse attribute	should
	       be  displayed  in  color.  Note that setting colorMode off 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
	       underline and color.

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

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

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

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

       cursorBlink (class CursorBlink)
	       Specifies  whether  to  make  the cursor	blink.	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
	       cycle-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
	       selected.  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
	       sequence.   Leading  non-digit  characters  are	ignored, e.g.,
	       "vt100" and "100" are the same.	The default is "420".

       defaultString (class DefaultString)
	       Specify the character (or string) which xterm  will  substitute
	       when  pasted  text  includes a character	which cannot be	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
	       default 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
		    order.

	       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
	       assigned	to different attributes	are recognized.

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

       eightBitInput (class EightBitInput)
	       If "true", Meta characters (a  single-byte  character  combined
	       with  the  Meta	modifier key) input from the keyboard are 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
	       defines	modifiers  for shift, (caps) lock and control, as well
	       as 5 additional modifiers which are generally used to configure
	       key modifiers.  Xterm inspects the same information to find the
	       modifier	associated with	either Meta key	(left or  right),  and
	       uses that key as	the Meta modifier.  It also looks for the 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
	       default is "locale".

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

	       false
		    The	key is sent unmodified.

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

	       true The	key is sent modified.

	       never
		    The	key is always sent unmodified.

	       Except for the never choice, xterm honors the terminfo 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
	       SELECT/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
	       resource	 is  not given,	xterm will use a scaled	version	of the
	       font given by faceName.

       faceSize	(class FaceSize)
	       Specify the pointsize for  fonts	 selected  from	 the  FreeType
	       library	if  support  for that library was compiled into	xterm.
	       The default is "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
	       default is "true".  If disabled,	xterm  will  simulate  double-
	       sized  characters  by  drawing  normal  characters  with	spaces
	       between them.

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

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

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

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

	       The default is "1".

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

	       o   The fixed-pitch ISO-8859-*-encoded fonts used by xterm 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
		  (default).

	       1  send modified	keys as	parameters for CSI u.

       freeBoldBox (class FreeBoldBox)
	       Specifies  whether  xterm  should assume	the bounding boxes for
	       normal and bold fonts are compatible.  If "false",  xterm  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
	       default 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
	       resource	disables the check.

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

	       HCM
		  highlightColorMode

	       HR highlightReverse

	       HBG
		  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
	       internal	state of each cell so it is not	considered a blank for
	       the purpose of selection.  Blanks written since the last	 erase
	       are  selectable.	 If you	do not wish to have trailing blanks in
	       a selection, use	the trimSelection resource.

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

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

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

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

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

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

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

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

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

       italicULMode (class ColorAttrMode)
	       Specifies  whether  characters  with  the  underline  attribute
	       should  be displayed in an italic font or as underlined 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
	       default 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
	       resource	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
	       locale encodings	and UTF-8 which	is used	with the -lc option or
	       locale resource.	 The help message shown	by "xterm -help" lists
	       the  default value, which depends on your system	configuration.

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

		   *localeFilter: xterm-filter -p

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

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

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

       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
	       input  from the keyboard	are handled according to the eightBit-
	       Input 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
	       resource	which can override this.  The default is "false".

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

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

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

	       -1   disables the feature.

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

	       1    prefixes modified sequences	with CSI.

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

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

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

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

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

	       0    The	legacy/vt220 keyboards interpret only the Control-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
	       sequence	for other keys (such as	"2")  when  modified  by  Con-
	       trol-,  Alt- or Meta-modifiers.	This feature does not apply to
	       function	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
	       resource.   Also	 (when sunKeyboard is false), similar logic is
	       used to find the	modifier associated with the  left  and	 right
	       Alt keys.  The default is "true".

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

	       Setting this resource has the same effect as setting  the  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
	       described in the	SELECTION section (see POINTER USAGE).	Multi-
	       ple 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
	       actual name).

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

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

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

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

       printModeImmediate (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
	       reconstruct  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
	       resource.  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
		   being  used.	  In  that  case, only the alternate screen is
		   selectd.

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

		   8  selects the saved	lines.

		   4  selects the alternate screen.

		   2  selects the normal screen.

		   1  selects the current screen, which	can be either the 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
	       application 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
	       device control string, e.g., for	DECGCI.	 If  not  true,	 color
	       registers  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
	       expects 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
	       behavior	 in  R4.   SouthWest  (the default) specifies that the
	       bottom line of text on the screen stay fixed.  If the window is
	       made  taller, additional	saved lines will be scrolled down onto
	       the screen; if the  window  is  made  shorter,  lines  will  be
	       scrolled	 off  the  top	of the screen, and the top saved lines
	       will be dropped.

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

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

	       There are several aspects to reverse video in xterm:

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

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

	       o   After startup, the user  can	 toggle	 the  "Enable  Reverse
		   Video"  menu	 entry.	 This exchanges	the current foreground
		   and background colors of the	VT100 widget, and repaints the
		   screen.  Because of the X resource hierarchy, the 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
	       region.	 This  corresponds  to xterm's private mode 1011.  The
	       default is "false".

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

       scrollTtyOutput (class ScrollCond)
	       Specifies whether or not	output to the terminal should 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
	       default 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",
	       because	the  intent  of	this option is to provide a picture of
	       the full-screen application's display on	the scrollback without
	       wiping  out the text that would be shown	before the application
	       was initialized.	 The default for this resource is "false".

       titeInhibit (class TiteInhibit)
	       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
		  resource  was	 set,  to  false  (0)  or always (2).  See the
		  locale  resource  for	 additional  discussion	 of  non-UTF-8
		  locales.

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

       utf8Fonts (class	Utf8Fonts)
	       See the discussion of  the  locale  resource.   This  specifies
	       whether	xterm will use UTF-8 fonts specified via resource 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
	       "default".

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

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

	       true (1)
		      Use  the UTF-8 fonts.  The menu entry is enabled,	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,
		      according	to the effective value of the utf8 resource.

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

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

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

	       However,	some users may wish to write a title string encoded in
	       UTF-8.	The  window  manager is	responsible for	drawing	window
	       titles.	Some window managers (not all) support UTF-8  encoding
	       of  window  titles.  Set	this resource to "true"	to 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
	       "Title Modes" in	the control sequences  document),  to  set  an
	       equivalent  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
	       default value is	"*".  This matches every font, the  X  library
	       automatically  chooses fonts with proper	charsets.  The ximFont
	       resource	is provided to override	this default font setting.

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

	       Specifies font number 3 to use in the Tektronix window.

       fontLarge (class	Font)
	       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
	       default 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

   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
       releasing 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
       insert  it  into	 your favorite editor.	Since cut buffers are globally
       shared among different applications, you	may regard each	 as  a	"file"
       whose contents you know.	 The terminal emulator and other text programs
       should be treating it as	if it were a text  file,  i.e.,	 the  text  is
       delimited by new	lines.

   Scrolling
       The  scroll  region  displays the position and amount of	text currently
       showing in the window (highlighted) relative  to	 the  amount  of  text
       actually	saved.	As more	text is	saved (up to the maximum), the size of
       the highlighted area decreases.

       Clicking	button one with	the pointer in the  scroll  region  moves  the
       adjacent	line to	the top	of the display window.

       Clicking	 button	three moves the	top line of the	display	window down to
       the pointer position.

       Clicking	button two moves the display to	a position in the  saved  text
       that corresponds	to the pointer's position in the scrollbar.

   Tektronix Pointer
       Unlike  the 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
       encoding	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
       selection.

       The  PRIMARY  token  is	a  standard X feature, documented in the ICCCM
       (Inter-Client Communication Conventions Manual),	which states

	      The selection named by the atom PRIMARY is used for all commands
	      that  take  only a single	argument and is	the principal means of
	      communication between clients that use the selection  mechanism.

       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
       insert X's "defaultString" whose	value cannot be	set, and may simply be
       empty.	Xterm's	defaultString resource specifies the string to use for
       incomplete translations of the UTF8_STRING.

       You can alter the types which xterm tries using the eightBitSelectTypes
       or  utf8SelectTypes  resources.	For instance, you might	have some 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
       expressed 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
		     allowSendEvents 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
		     Media Copy	control	sequence CSI 1 0 i, for	example	from a
		     shell script with

			 printf	'\033[10i'

		     Only the UTF-8 encoding is	supported.

	      SVG Screen Dump (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
		     resource.

	      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
		     resource  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
		     accidentally typed	CTRL-Z,	suspending the process.

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

   VT Options
       The  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
		     resource.

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

	      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
		     resource.	There is also an escape	sequence (see the doc-
		     ument  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
		     alternate	screens.   This	corresponds to the titeInhibit
		     resource.	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
		     returning 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
		     affect 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
		     (often 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
		     options.  This  corresponds  to  the  VT102  RIS  control
		     sequence,	with  a	few obvious differences.  For example,
		     your session is not disconnected as a  real  VT102	 would
		     do.

	      Reset and	Clear Saved Lines (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
		     Sequences).

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

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

	      Bold Fonts
		     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
		     input/output.   It	 is  useful  for temporarily switching
		     xterm to display text from	an application which does  not
		     follow  the  locale settings.  It corresponds to the utf8
		     resource.

	      UTF-8 Fonts (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
	   everything you type at the keyboard.

       o   Any process which has access	to your	X display can manipulate it in
	   ways	that you might not anticipate, even redirecting	your  keyboard
	   to  itself  and sending events to your application's	windows.  This
	   is true even	with the "magic	cookie"	authorization  scheme.	 While
	   the allowSendEvents provides	some protection	against	rogue 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,
	   including the GrabKeyboard protocol.

       o   The	possibility  of	an application spying on your keystrokes is of
	   particular concern when you want to type in	a  password  or	 other
	   sensitive data.  The	best solution to this problem is to use	a 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
       directed	only to	xterm (using the GrabKeyboard protocol request).  When
       an application prompts you for a	password (or  other  sensitive	data),
       you  can	 enable	 Secure	Keyboard using the menu, type in the data, and
       then disable Secure Keyboard using the menu again.

       o   This	ensures	that you know which  window  is	 accepting  your  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
       reparenting window manager (that	places a title bar or other decoration
       around the window) while	in Secure Keyboard mode.  (This	is  a  feature
       of  the	X protocol not easily overcome.)  When this happens, the 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,
	   /*  BS   HT	 NL   VT   NP	CR   SO	  SI */
		1,  32,	  1,   1,   1,	 1,   1,   1,
	   /* DLE  DC1	DC2  DC3  DC4  NAK  SYN	 ETB */
		1,   1,	  1,   1,   1,	 1,   1,   1,
	   /* CAN   EM	SUB  ESC   FS	GS   RS	  US */
		1,   1,	  1,   1,   1,	 1,   1,   1,
	   /*  SP    !	  "    #    $	 %    &	   ' */
	       32,  33,	 34,  35,  36,	37,  38,  39,
	   /*	(    )	  *    +    ,	 -    .	   / */
	       40,  41,	 42,  43,  44,	45,  46,  47,
	   /*	0    1	  2    3    4	 5    6	   7 */
	       48,  48,	 48,  48,  48,	48,  48,  48,
	   /*	8    9	  :    ;    <	 =    >	   ? */
	       48,  48,	 58,  59,  60,	61,  62,  63,
	   /*	@    A	  B    C    D	 E    F	   G */
	       64,  48,	 48,  48,  48,	48,  48,  48,
	   /*	H    I	  J    K    L	 M    N	   O */
	       48,  48,	 48,  48,  48,	48,  48,  48,
	   /*	P    Q	  R    S    T	 U    V	   W */
	       48,  48,	 48,  48,  48,	48,  48,  48,
	   /*	X    Y	  Z    [    \	 ]    ^	   _ */

	      For example, the string  "33:48,37:48,45-47:48,38:48"  indicates
	      that  the	 exclamation  mark, percent sign, dash,	period,	slash,
	      and ampersand characters should be treated the same way as 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
	       resource	and is also invoked by the allowsends entry  in	 main-
	       Menu.

       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
	       selection source	as in insert-selection.

	       The format parameter allows these substitutions:

	       %%   inserts a "%".

	       %P   the	screen-position	at the beginning  of  the  highlighted
		    region,  as	 a  semicolon-separated	pair of	integers using
		    the	values that the	CUP control sequence would use.

	       %p   the	screen-position	after the beginning of the highlighted
		    region, using the same convention as "%P".

	       %S   the	length of the string that "%s" would insert.

	       %s   the	content	of the selection, unmodified.

	       %T   the	length of the string that "%t" would insert.

	       %t   the	 selection,  trimmed  of  leading/trailing whitespace.
		    Embedded spaces (and newlines) are copied as is.

	       %R   the	length of the string that "%r" would insert.

	       %r   the	selection, trimmed of trailing whitespace.

	       %V   the	video attributes at the	beginning of  the  highlighted
		    region,  as	 a  semicolon-separated	list of	integers using
		    the	values that the	SGR control sequence would use.

	       %v   the	video attributes after	the  end  of  the  highlighted
		    region, using the same convention as "%V".

	       After constructing the command-string, xterm forks a subprocess
	       and executes the	 command,  which  completes  independently  of
	       xterm.

	       For  example, this translation would invoke a new xterm process
	       to view a file whose name is selected while holding  the	 shift
	       key  down.  The new process is started when the mouse button is
	       released:

		   *VT100*translations:	#override Shift	\
		       <Btn1Up>: exec-formatted("xterm -e view '%t'", SELECT)

       exec-selectable(format, onClicks)
	       Execute an external command, using data copied from the	screen
	       for  part  of  the  command's parameters.  The first parameter,
	       format gives the	basic command as in exec-formatted.  The  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
	       depends	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
	       parameter,  format  gives the template for the data as in exec-
	       formatted.  The second parameter	specifies the method for copy-
	       ing 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
	       order  given  (case  is	significant) until one is found.  Com-
	       monly-used selections include: PRIMARY,	SECONDARY,  and	 CLIP-
	       BOARD.	Cut  buffers  are  typically named CUT_BUFFER0 through
	       CUT_BUFFER7.

       insert-seven-bit()
	       This action is a	synonym	for insert().  The term	"seven-bit" is
	       misleading:  it only implies that xterm does not	try to add 128
	       to the key's value as in	insert-eight-bit().

       interpret(control-sequence)
	       Interpret the given control  sequence  locally,	i.e.,  without
	       passing	it  to	the host.  This	works by inserting the control
	       sequence	at the front of	the input buffer.  Use "\"  to	escape
	       octal  digits  in  the  string.	Xt does	not allow you to put a
	       null character (i.e., "\000") in	the string.

       keymap(name)
	       This action dynamically defines a new translation  table	 whose
	       resource	 name is name with the suffix Keymap (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
	       select-fonts, since those are not based on resource values.  It
	       does  affect  the  fonts	 loosely organized under the "Default"
	       menu entry, including font, boldFont,  wideFont	and  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
	       ignoring	case:

	       noFormFeed
		    no	form  feed  will  be  sent at the end of the last line
		    printed (i.e., printerFormFeed is ``false'').

	       FormFeed
		    a form feed	will be	sent at	 the  end  of  the  last  line
		    printed (i.e., printerFormFeed is ``true'').

	       noNewLine
		    no	newline	 will  be  sent	 at  the  end of the last line
		    printed, and wrapped lines	will  be  combined  into  long
		    lines (i.e., printerNewLine	is ``false'').

	       NewLine
		    a  newline	will  be  sent	at  the	 end  of the last line
		    printed, and each line will	be limited (by adding  a  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
	       redraw entry in mainMenu.

       restore()
	       Restores	the window to the size before it was last maximized.

       scroll-back(count [,units [,mouse] ])
	       This action scrolls the text window backward so that text  that
	       had  previously scrolled	off the	top of the screen is now 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()

	       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.

	       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.

   Default Key Bindings
       The default bindings in the VT102 window	use the	SELECT token, which is
       set by the selectToClipboard resource.  These are for the vt100 widget:

		     Shift <KeyPress> Prior:scroll-back(1,halfpage) \n\
		      Shift <KeyPress> Next:scroll-forw(1,halfpage) \n\
		    Shift <KeyPress> Select:select-cursor-start() \

	     Lock @Num_Lock Ctrl <Btn4Down>:scroll-back(1,halfpage,m) \n\
		  @Num_Lock Ctrl <Btn4Down>:scroll-back(1,halfpage,m) \n\
				 <Btn4Down>:scroll-back(5,line,m)     \n\
			    Ctrl <Btn5Down>:scroll-forw(1,halfpage,m) \n\
		       Lock Ctrl <Btn5Down>:scroll-forw(1,halfpage,m) \n\
	     Lock @Num_Lock Ctrl <Btn5Down>:scroll-forw(1,halfpage,m) \n\

				 <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
       extensive.  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
       select/paste operation.	It is important	to remember however, that  cut
       buffers	store  data in ISO-8859-1 encoding, while selections can store
       data in a variety of formats  and  encodings.   While  xterm  owns  the
       selection,  it  highlights it.  When it loses the selection, it removes
       the corresponding highlight.  But you can still paste from  the	corre-
       sponding	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
       resources 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
       "actions"  which	 those	translations  use.   Because the scrollbar (or
       menubar)	widgets	do not recognize these actions (but because it	has  a
       corresponding translation), they	are passed on to the vt100 widget.

       This augmenting of the scrollbar's translations has a few limitations:

       o   Xterm  knows	 what  the  default  translations are, but there is no
	   suitable library interface for determining  what  customizations  a
	   user	 may have added	to the vt100 widget.  All that xterm can do is
	   augment the scrollbar widget	to give	it the same starting point for
	   further customization by the	user.

       o   Events in the gap between the widgets may be	lost.

       o   Compose  sequences  begun  in one widget cannot be completed	in the
	   other, because the input methods for	each widget do not share  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
	   existing terminals),	the format of those sequences usually conforms
	   to the host-to-terminal standard.

       o   Some	 of  xterm's  sequences	 do  not fit into the standard scheme.
	   Technically those are "unspecified".	 As  an	 example,  DEC	Screen
	   Alignment Test (DECALN) is this three-character sequence:

	       ESC # 8

       o   Some	 sequences fit into the	standard format, but are not listed in
	   the standard.  These	include	the  sequences	used  for  setting  up
	   scrolling margins and doing forward/reverse scrolling.

       o   Some	 of  the  sequences (in	particular, the	single-character 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
       interpret  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"
	   sequences such as the control sequence for cursor-up	when  pressing
	   the up-arrow, and

       o   application mode, which uses	a different control sequence that 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
       example,	some shells (unlike ksh(1), which appears  to  be  hard-coded,
       not  even  using	 termcap) allow	their users to customize key-bindings,
       assigning shell actions to special keys.

       o   bash(1) allows constant strings to be assigned to functions.	  This
	   is  only  successful	 if the	terminal is initialized	to application
	   mode	by default, because bash lacks flexibility in this  area.   It
	   uses	 a  (less  expressive than bash's) readline scripting language
	   for setting up key bindings,	which relies upon the user  to	stati-
	   cally enumerate the possible	bindings for given values of $TERM.

       o   zsh(1)  provides  an	 analogous  feature,  but  it  accepts runtime
	   expressions,	as well	as providing a $terminfo  array	 for  scripts.
	   In particular, one can use the terminal database, transforming when
	   defining a key-binding.  By transforming the	output so that CSI and
	   SS3 are equated, zsh	can use	the terminal database to obtain	useful
	   definitions for its command-line use	regardless of whether the 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
	    Attributes (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
       below, with a brief explanation.

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.
