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.
	       This  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.

       -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",	"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 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	"/"):

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

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

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

       %geom   This option specifies the preferred size	and  position  of  the
	       Tektronix  window.  It is shorthand for specifying the "*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	 instead  of  standard	escape
	       sequences.

	       See also	the keyboardType resource.

       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 and	sunKeyboard.  The resource's value should  be  one  of
	       the   corresponding  strings  "hp",  "sco",  "sun",  "tcap"  or
	       "vt220".	 The individual	resources are provided for legacy sup-
	       port; this resource is simpler to use.

	       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  instead  of standard	escape
	       sequences.

	       See also	the keyboardType resource.

       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  instead  of standard	escape
	       sequences.

	       See also	the keyboardType resource.

       sunKeyboard (class SunKeyboard)
	       Specifies whether or  not  Sun/PC  keyboard  layout  should  be
	       assumed	rather	than DEC VT220.	 This causes the keypad	"+" to
	       be mapped to ",".  and CTRL F1-F10 to F11-F20, depending	on the
	       setting	of  the	 ctrlFKeys  resource,  so xterm	emulates a DEC
	       VT220 more accurately.  Otherwise (the  default,	 with  sunKey-
	       board  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  should  be	generated for function
	       keys instead of standard	 escape	 sequences.   The  default  is
	       "false",	i.e., this feature is disabled.

	       See also	the keyboardType resource.

       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 4.  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.

	       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.

	       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 control sequences for func-
	       tion  keys F1 to	F4, for	compatibility with X Consortium	xterm.
	       Otherwise, it uses the VT100-style codes	for PF1	to  PF4.   The
	       default is "false".

       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-immediately 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 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
       classes	of  the	 entries  in  each  of	the  menus  are	 listed	below.

   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.

       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 */

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

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

       set-8-bit-control(on/off/toggle)
	       This   action  sets,  unsets  or	 toggles  the  eightBitControl
	       resource.  It is	also invoked from the 8-bit-control  entry  in
	       vtMenu.

       set-allow132(on/off/toggle)
	       This  action  sets, unsets or toggles the c132 resource.	 It is
	       also invoked from the allow132 entry in vtMenu.

	       This  action  sets,  unsets or toggles the handling Application
	       Cursor Key mode and is also invoked by the appcursor  entry  in
	       vtMenu.

       set-appkeypad(on/off/toggle)
	       This action sets, unsets	or toggles the handling	of Application
	       Keypad mode and is also	invoked	 by  the  appkeypad  entry  in
	       vtMenu.

       set-autolinefeed(on/off/toggle)
	       This  action  sets,  unsets  or	toggles	automatic insertion of
	       linefeeds.  It is also invoked by  the  autolinefeed  entry  in
	       vtMenu.

       set-autowrap(on/off/toggle)
	       This  action sets, unsets or toggles automatic wrapping of long
	       lines.  It is also invoked by the autowrap entry	in vtMenu.

	       It is also invoked by the jumpscroll entry in vtMenu.

       set-font-linedrawing(on/off/toggle)
	       This action sets, unsets	or toggles the xterm's state regarding
	       whether	the  current  font  has	 line-drawing  characters  and
	       whether	it  should  draw them directly.	 It is also invoked by
	       the font-linedrawing entry in fontMenu.

       set-font-packed(on/off/toggle)
	       This action  sets,  unsets  or  toggles	the  forcePackedFont's

	       It is also invoked by the visualbell entry in vtMenu.

       set-vt-font(d/1/2/3/4/5/6/e/s [,normalfont [, boldfont]])
	       This  action sets the font or fonts currently being used	in the
	       VT102 window.  The first	argument is a  single  character  that
	       specifies the font to be	used:

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

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

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

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

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

       smaller-vt-font()
	       Set the font to the next	smaller	one, based on the font	dimen-
	       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() \
					    select-cursor-end(SELECT, CUT_BUFFER0) \n\
		    Shift <KeyPress> Insert:insert-selection(SELECT, CUT_BUFFER0) \n\
			    Alt	<Key>Return:fullscreen() \n\
		   <KeyRelease>	Scroll_Lock:scroll-lock() \n\
	       Shift~Ctrl <KeyPress> KP_Add:larger-vt-font() \n\
	       Shift Ctrl <KeyPress> KP_Add:smaller-vt-font() \n\
	       Shift <KeyPress>	KP_Subtract:smaller-vt-font() \n\
			   ~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\
		! @Num_Lock Ctrl <Btn1Down>:popup-menu(mainMenu) \n\
			   ~Meta <Btn1Down>:select-start() \n\
			 ~Meta <Btn1Motion>:select-extend() \n\
			   !Ctrl <Btn2Down>:popup-menu(vtMenu) \n\
		      !Lock Ctrl <Btn2Down>:popup-menu(vtMenu) \n\
	    !Lock Ctrl @Num_Lock <Btn2Down>:popup-menu(vtMenu) \n\
		! @Num_Lock Ctrl <Btn2Down>:popup-menu(vtMenu) \n\
		     ~Ctrl ~Meta <Btn2Down>:ignore() \n\
			    Meta <Btn2Down>:clear-saved-lines()	\n\
		       ~Ctrl ~Meta <Btn2Up>:insert-selection(SELECT, CUT_BUFFER0) \n\
			   !Ctrl <Btn3Down>:popup-menu(fontMenu) \n\
		      !Lock Ctrl <Btn3Down>:popup-menu(fontMenu) \n\
	    !Lock Ctrl @Num_Lock <Btn3Down>:popup-menu(fontMenu) \n\
		! @Num_Lock Ctrl <Btn3Down>:popup-menu(fontMenu) \n\
		     ~Ctrl ~Meta <Btn3Down>:start-extend() \n\
			 ~Meta <Btn3Motion>:select-extend() \n\
			    Ctrl <Btn4Down>:scroll-back(1,halfpage,m) \n\
		       Lock Ctrl <Btn4Down>:scroll-back(1,halfpage,m) \n\
	     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\
		  @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.
