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  (VTxxx)  and  Tektronix   4014   compatible
       terminals  for programs that cannot use the window system directly.  If
       the underlying operating system supports terminal resizing capabilities
       (for  example,  the  SIGWINCH  signal  in systems derived from 4.3bsd),
       xterm will use the facilities to notify programs running in the  window
       whenever it is resized.

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

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

EMULATIONS

       The   VT102   emulation  is  fairly  complete,  but  does  not  support
       autorepeat.  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.   Termcap(5)  entries  that  work
       with  xterm  include  an  optional  platform-specific  entry,  "xterm,"
       "vt102," "vt100," "ansi" and "dumb."  xterm automatically searches  the
       termcap  file  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  emulation  level  with the decTerminalID
       resource.  (The "TERMCAP" environment variable is not set if  xterm  is
       linked  against  a terminfo library, since the requisite information is
       not provided by the termcap emulation of terminfo libraries).

       Many of the special  xterm  features  may  be  modified  under  program
       control  through  a set of escape sequences different from the standard
       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
       directory  xterm  is  started  in,  or  the  home directory for a login
       xterm).

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

OTHER FEATURES

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

       In 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 termcap(5)
       entry  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
       (currently 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.  The -version and -help options are interpreted even if
       xterm  cannot  open  the  display,  and  are  useful  for  testing  and
       configuration scripts:

       -version
               This  causes  xterm  to  print a version number to the standard
               output.

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

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

       One parameter (after all options) may be given.  That overrides xterm's
       built-in  choice  of  shell  program.   Normally xterm checks the SHELL
       variable.  If that is not set, xterm tries to  use  the  shell  program
       specified  in  the  password  file.   If  that  is  not set, xterm uses
       /bin/sh.  If the parameter names an executable file,  xterm  uses  that
       instead.   The parameter must be an absolute path, or name a file found
       on the user's PATH (and thereby construct an absolute  path).   The  -e
       option  cannot be used with this parameter since it uses all parameters
       following the option.

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

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

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

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

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

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

       -aw     This option indicates that auto-wraparound should  be  allowed.
               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
               distance  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
               cursorOffTime resource.

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

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

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

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

       -cc characterclassrange:value[,...]
               This sets classes indicated by the given ranges  for  using  in
               selecting  by  words.   See  the  section  specifying character
               classes.  and discussion of the charClass resource.

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

       +cjk_width
               Reset the cjkWidth resource.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

               See  also  the  discussion  of  boldMode   and   alwaysBoldMode
               resources.

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

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

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

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

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

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

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

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

               See also the discussion of the iconFont resource.

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

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

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

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

               See also the discussion of the ximFont resource.

       -hc color
               (see -selbg).

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

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

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

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

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

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

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

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

       -im     Turn  on the useInsertMode resource, which forces use of insert
               mode by adding appropriate entries to the  TERMCAP  environment
               variable.

       +im     Turn off the useInsertMode resource.

       -into windowId
               Given  an  X  window identifier (a decimal integer), xterm will
               reparent its top-level shell widget to that  window.   This  is
               used to embed xterm within other applications.

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

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

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

       +k8     This option resets the allowC1Printable resource.

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

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

               The   value  "default",  suppresses  the  associated  resources
               hpFunctionKeys,        scoFunctionKeys,        sunFunctionKeys,
               tcapFunctionKeys  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
               corresponds to the locale resource.

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

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

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

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

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

       -lf filename
               Specify the log-filename.  See the -l option.

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

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

               If you do want the effect of -ls and -e simultaneously, you may
               get away with something like
                      xterm -e /bin/bash -l -c "my command here"

               Finally,  -ls  is  not completely ignored, because xterm -ls -e
               does write a /var/log/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 maximize its layout on startup.

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

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

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

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

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

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

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

       +mk_width
               Reset the mkWidth resource.

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

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

       -nul    This option disables the display of underlining.

       +nul    This option enables the display of underlining.

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

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

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

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

       -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.

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

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

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

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

       -sl number
               This option specifies the number of lines  to  save  that  have
               been  scrolled  off the top of the screen.  This corresponds to
               the saveLines resource.  The default is 64.

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

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

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

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

       -t      This  option  indicates  that  xterm  should start in Tektronix
               mode, rather than in VT102 mode.   Switching  between  the  two
               windows  is done using the "Options" menus.  Termcap(5) entries
               that  work  with   xterm   "tek4014,"   "tek4015,"   "tek4012,"
               "tek4013," "tek4010," and "dumb."  xterm automatically searches
               the termcap file in this order for these entries and then  sets
               the "TERM" and the "TERMCAP" 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, and
               vt220 (the "vt" is  optional).   The  default  is  vt100.   The
               term_id  argument  specifies  the terminal ID to use.  (This is
               the same as the decTerminalID resource).

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

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

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

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

       +u8     This option resets the utf8 resource.

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

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

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

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

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

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

       -ut     This option indicates that xterm should not write a record into
               the 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 you do not set this resource to "true",  xterm  will  ignore
               the  escape  sequence  which  turns UTF-8 mode on and off.  The
               default is "false".

       +wc     This option resets the wideChars resource.

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

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

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

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

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

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

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

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

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

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

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

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

       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
               surrounding the window.

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

       -display display
               This option specifies the X server to contact; see X(7).

       -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(7).

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

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

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

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

       -title string
               This  option  specifies  the  window title string, which may be
               displayed by window managers  if  the  user  so  chooses.   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
               separate 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:

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

       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.

       iconName (class IconName)
               Specifies the icon name.  The default is the application  name.

       keyboardType (class KeyboardType)
               Enables  one  (or none) of the various keyboard-type resources:
               hpFunctionKeys,        scoFunctionKeys,        sunFunctionKeys,
               tcapFunctionKeys  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
               support; this resource is simpler to use.

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

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

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

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

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

       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  modify  this.   The
               default is "false".

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

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

       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".

       scoFunctionKeys (class ScoFunctionKeys)
               Specifies whether or not SCP 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-F12 to F11-F20, depending on the
               setting  of  the  ctrlFKeys  resource.  so xterm emulates a DEC
               VT220  more   accurately.    Otherwise   (the   default,   with
               sunKeyboard  set  to "false"), xterm uses PC-style bindings for
               the function keys and keypad.

               PC-style bindings use the Shift, Alt, Control and Meta keys  as
               modifiers  for function-keys and keypad (see 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.

               See also the keyboardType resource.

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

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

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

       ttyModes (class TtyModes)
               Specifies a string containing terminal setting keywords 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
               literal backslash in an X resource escapes the next  character.

               This  is  very  useful  for  overriding  the  default  terminal
               settings 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.  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
               window map before starting the subprocess.  This is part of the
               ptyHandshake logic.  When xterm is directed  to  wait  in  this
               fashion,  it  passes  the terminal size from the display end of
               the pseudo-terminal  to  the  terminal  I/O  connection,  e.g.,
               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
               iconified  will  cause  an  XBell sound at the given volume and
               have  "***"  prepended  to  their  icon  titles.   Most  window
               managers will detect this change immediately, showing you which
               window has the output.  (A similar feature was in  x10  xterm.)
               The default is "false."

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

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

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

       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 "false."

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

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

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

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

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

               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:

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

               -  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.

               If "true",  Alt  characters  (a  character  combined  with  the
               modifier  associated  with  left/right  Alt-keys) are converted
               into  a  two-character  sequence  with  the  character   itself
               preceded  by ESC.  This applies as well to function key control
               sequences, unless xterm sees that  Alt  is  used  in  your  key
               translations.   If  "false",  Alt  characters  input  from  the
               keyboard  cause  a  shift  to  8-bit  characters   (just   like
               metaSendsEscape).   By  combining  the Alt- and Meta-modifiers,
               you can create corresponding  combinations  of  ESC-prefix  and
               8-bit characters.  The default is "false."

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

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

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

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

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

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

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

       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  the  xterm  uses  a  50  millisecond
               timeout  to  await  input  (i.e.,  to  support  the Xaw3d arrow
               scrollbar).  The default is "false."

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

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

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

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

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

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

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

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

               See   also   the  discussion  of  boldMode  and  alwaysBoldMode
               resources.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

       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
               "XtDefaultForeground."

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

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

       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."

       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."

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

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

       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."

       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 100.

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

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

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

       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
               1,2,3,4,5,6,7,8,9,11,13,14,18,19,20,21,GetSelection,SetSelection,SetWinLines,SetXprop
       (i.e. no operations are allowed).

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

               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).

               MinimizeWin (2)
                    Iconify window.

               PopTitle (23)

               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
               presented as a single character with the eighth bit turned  on.
               The  terminal  is  put  into  8-bit  mode.   If  "false",  Meta
               characters are converted into a two-character sequence with the
               character  itself  preceded by ESC.  On startup, xterm tries to
               put the terminal into  7-bit  mode.   The  metaSendsEscape  and
               altSendsEscape  resources  may  override  this.  The default is
               "true."

               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.    xmodmap  lists  your  key  modifiers.   X  defines
               modifiers for shift, (caps) lock and  control,  as  well  as  5
               additional  modifiers which are generally used to configure key
               modifiers.  xterm inspects the same  information  to  find  the
               modifier  associated  with either Meta key (left or right), and
               uses that key as the Meta modifier.   It  also  looks  for  the
               NumLock key, to recognize the modifier which is associated with
               that.

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

       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, which does not override anything.

       faceName (class FaceName)
               Specify the  pattern  for  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 font and related resources.

       faceNameDoublesize (class FaceNameDoublesize)
               Specify  an  double-width  font  for cases where an application
               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."  On the VT Fonts menu, this corresponds to
               the Default entry.

               Although the default is "14.", 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.".  If you set faceSize to
               match the size of  the  bitmap  font,  then  switching  between
               bitmap   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.

       font2 (class Font2)
               Specifies the name of the second alternative font.

       font3 (class Font3)
               Specifies the name of the third alternative font.

       font4 (class Font4)
               Specifies the name of the fourth alternative font.

       font5 (class Font5)
               Specifies the name of the fifth alternative font.

       font6 (class Font6)
               Specifies the name of the sixth alternative font.

       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.

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

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

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

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

       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
               modified keys with the modifyOtherKeys resource.

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

               1  send modified keys as parameters for CSI u.

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

       geometry (class Geometry)
               Specifies the preferred size and position of the 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
               highlightColor  to  override the reversed foreground/background
               colors in a selection.  The default is unspecified: at startup,
               xterm checks if those resources are set to something other than
               the default foreground and  background  colors.   Setting  this
               resource disables the check.

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

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

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

       highlightSelection (class HighlightSelection)
               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
               positions that contain text that can be selected.  The  default
               is "false."

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

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

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

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

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

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

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

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

       inputMethod (class 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
               characters.  It is implemented only for TrueType fonts.

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

       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
                   according to utf8 resource or -u8 option.

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

               Regardless of your locale and encoding, you need an ISO-10646-1
               font to display the result.  Your configuration may not include
               this  font,  or  locale-support by xterm may not be needed.  At
               startup, xterm uses a  mechanism  equivalent  to  the  load-vt-
               fonts(utf8Fonts, Utf8Fonts)    action   to   load   font   name
               subresources of the VT100 widget.  That is,  resource  patterns
               such  as  "*vt100.utf8Fonts.font"  will be loaded, and (if this
               resource  is  enabled),  override  the  normal  fonts.   If  no
               subresources are found, the normal fonts such as "*vt100.font",
               etc., are used.  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
               should   put  those  within  a  shell  script  to  execute  the
               converter, and set this resource to point to the shell  script.

       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
               eightBitInput resource.  The default is "false."

       mkSamplePass (class MkSamplePass)
               If  mkSampleSize  is  nonzero,  and  mkWidth (and cjkWidth) are
               false, on startup xterm compares its  built-in  tables  to  the
               system's wide character width data to decide if it will use the
               system's data.   It  tests  the  first  mkSampleSize  character
               values,  and  allows  up  to mkSamplePass mismatches before the
               test fails.  The default (for the allowed number of mismatches)
               is 256.

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

               Set it to -1 to disable it.
               Set it to 0 to use the old/obsolete behavior.
               Set it to 1 to prefix modified sequences with CSI.
               Set it to 2 to force the modifier to be the second parameter if
               it would otherwise be the first.
               Set  it to 3 to mark the sequence with a ">" to hint that it is
               private.

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

               Set it to -1 to permit the user  to  use  shift-  and  control-
               modifiers  to  construct  function-key strings using the normal
               encoding scheme.
               Set it to 0 to use the old/obsolete behavior.
               Set it to 1 to prefix modified sequences with CSI.
               Set it to 2 to force the modifier to be the second parameter if
               it would otherwise be the first.
               Set  it to 3 to mark 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.

               As  a  special  case,  legacy (when oldFunctionKeys is true) or
               vt220 (when sunKeyboard is true) keyboards interpret  only  the
               Control-modifier   when  constructing  numbered  function-keys.
               This is done to provide compatible keyboards for DEC VT220  and
               related terminals that implement user-defined keys (UDK).

       modifyOtherKeys (class ModifyOtherKeys)
               Like  modifyCursorKeys,  tells  xterm  to  construct  an escape
               sequence  for  other  keys  (such  as  "2")  when  modified  by
               Control-,  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
                    control  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
               asynchronously.  The default is "false."

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

       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
               function  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).
               Multiple mouse clicks (using the  button  which  activates  the
               select-start  action) are interpreted according to the resource
               values of on2Clicks, etc.  The resource value  can  be  one  of
               these:

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

               line
                  Select a line (counting wrapping).

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

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

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

               regex
                  Select a "word" as  determined  by  the  regular  expression
                  which follows in the resource value.

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

               The default values for on2Clicks and on3Clicks are  "word"  and
               "line",  respectively.  There is no default value for on4Clicks
               or  on5Clicks,  making  those  inactive.   On  startup,   xterm
               determines  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.

       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.  A
               "0" disables the attributes.  A "1" prints the  normal  set  of
               attributes  (bold, underline, inverse and blink) as VT100-style
               control sequences.  A "2" prints ANSI color attributes as well.
               The default is "1."

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

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

       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."

       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
                    switching  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."

       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
               widget and the scrollbar.  The default value is 1.

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

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

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

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

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

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

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

       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."

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

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

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

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

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

       titeInhibit (class TiteInhibit)
               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 utf8Titles
                    resource).

               3    Query window/icon labels using UTF-8

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

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

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

       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 is an  integer,  expected  to  range
               from 0 to 3:

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

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

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

               3  This is the default value of the resource.   It  is  changed
                  during   initialization  depending  on  whether  the  locale
                  resource was set, to 0 or 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.

       utf8Latin1 (class Utf8Latin1)
               If true, allow an ISO-8859-1 normal font to be combined with an
               ISO-10646 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,  which  does  not  override
               anything.

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

               However, some users may wish to write a title string encoded in
               UTF-8.   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
               specified  by  colorBD,  colorBL,  colorRV  and  colorUL.   The
               resource value is the sum of values for each attribute:
                 1 for reverse,
                 2 for underline,
                 4 for bold and
                 8 for blink.

               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."

       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.

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

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

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

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

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

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

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

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

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

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

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

   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):

              -  Double-clicking selects by words.

              -  Triple-clicking selects by lines.

              -  Quadruple-clicking goes back to characters, etc.

       Multiple-click is determined by the time from button up to button down,
       so  you  can  change  the  selection unit in the middle of a selection.
       Logical words and lines selected by double- or triple-clicking may wrap
       across  more than one screen line if lines were wrapped by xterm itself
       rather  than  by  the  application  running  in  the  window.   If  the
       key/button  bindings  specify  that an X selection is to be made, xterm
       will leave the selected text highlighted for  as  long  as  it  is  the
       selection owner.

       Pointer  button two (usually middle) "types" (pastes) the text from the
       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
       command to the shell, for example, or take output from  a  program  and
       insert  it  into  your favorite editor.  Since cut buffers are globally
       shared among different applications, you may regard each  as  a  "file"
       whose contents you know.  The terminal emulator and other text programs
       should be treating it as if it were a text  file,  i.e.,  the  text  is
       delimited by new lines.

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

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

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

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

   TEKTRONIX POINTER
       Unlike  the  VT102  window,  the  Tektronix  window  does not allow the
       copying of text.  It does allow Tektronix GIN mode, and  in  this  mode
       the cursor will change from an arrow to a cross.  Pressing any key will
       send that key and the current coordinate of the cross cursor.  Pressing
       button  one,  two,  or three will return the letters "l", "m", and "r",
       respectively.  If the "shift" key is pressed when a pointer  button  is
       pressed, the corresponding upper case letter is sent.  To distinguish a
       pointer button from a key, the high bit of the character  is  set  (but
       this  is  bit is normally stripped unless the terminal mode is RAW; see
       tty(4) for details).

SELECT/PASTE

       X clients provide select and paste support by  responding  to  requests
       conveyed by the 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.

   SELECTION TARGETS
       The  different  types  of  data  which  are  passed  depend on what the
       receiving client asks for.  These are termed selection targets.

       When asking for the selection data, xterm tries the following types  in
       this order:

              UTF8_STRING
                   This  is  an XFree86 extension, which denotes that the data
                   is encoded in  UTF-8.   When  xterm  is  built  with  wide-
                   character  support, it both accepts and provides this type.

              TEXT the text is in  the  encoding  which  corresponds  to  your
                   current locale.

              COMPOUND_TEXT
                   this  is  a format for multiple character set data, such as
                   multi-lingual text.  It can store UTF-8 data as  a  special
                   case.

              STRING
                   This is Latin 1 (ISO-8859-1) data.

       The  middle  two  (TEXT  and  COMPOUND_TEXT)  are  added  if  xterm  is
       configured with the i18nSelections resource set to "true".

       UTF8_STRING is preferred (therefore first  in  the  list)  since  xterm
       stores text as Unicode data when running in wide-character mode, and no
       translation is needed.  On the other hand, TEXT and  COMPOUND_TEXT  may
       require  translation.   If  the  translation  is  incomplete, they will
       insert X's "defaultString" whose value cannot be set, and may simply be
       empty.   Xterm's defaultString resource specifies the string to use for
       incomplete translations of the UTF8_STRING.

       You can alter the types which xterm tries using the eightBitSelectTypes
       or  utf8SelectTypes  resources.   For  instance,  you  might  have some
       specific locale  setting  which  does  not  use  UTF-8  encoding.   The
       resource  value  is  a  comma-separated  list of the selection targets,
       which consist of the names shown.  You can use the special name I18N to
       denote the optional inclusion of TEXT and COMPOUND_TEXT.  The names are
       matched ignoring case, and can be abbreviated.  The default list can be
       expressed in several ways, e.g.,

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

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
                     passwords  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
                     environments.

       Commands for capturing output:

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

              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)
                     character.    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-
                     character 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,
                     scoFunctionKeys 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 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
                     corresponds  to  the appcursorDefault resource.  There is
                     no corresponding command-line option.

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

              Scroll to Bottom on Key Press (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
                     corresponds  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
                     keepSelection  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
                     Control-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
                     document 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
                     corresponds   to   the  -ai  option  and  the  activeIcon
                     resource.

       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
                     corresponds 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
                     window.

              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
       window,  or modifies the way the font is specified or displayed.  There
       are several sections.

       The first section  allows  you  to  select  the  font  from  a  set  of
       alternatives:

              Default (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:

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

              Packed Font (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
                     characters.

       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 (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.

       The fourth section allows you to enable or disable  special  operations
       which  can  be  controlled by writing escape sequences to the terminal.
       These are disabled if the SendEvents feature is enabled:

              Allow Color Ops (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
                     terminal's notion of its function-key strings, as termcap
                     or  terminfo  capabilities.   This  corresponds  to   the
                     allowTcapOps resource.

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

              Allow Window Ops (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.   Most  servers,
       run  under  xdm,  are  capable  of using a "magic cookie" authorization
       scheme that can provide a reasonable level of security for many people.
       If  your  server is only using a host-based mechanism to control access
       to the server (see xhost(1)), then if you enable access for a host  and
       other  users are also permitted to run clients on that same host, it is
       possible that someone can run  an  application  which  uses  the  basic
       services  of  the  X  protocol to snoop on your activities, potentially
       capturing a transcript of everything you type  at  the  keyboard.   Any
       process  which  has  access to your X display can manipulate it in ways
       that you might not anticipate, even redirecting your keyboard to itself
       and  sending  events  to your application's windows.  This is true even
       with   the   "magic   cookie"   authorization   scheme.    While    the
       allowSendEvents  provides  some  protection  against rogue applications
       tampering with your programs, guarding against a snooper is harder.

       The possibility of an application  spying  on  your  keystrokes  is  of
       particular  concern  when  you  want  to  type  in  a password or other
       sensitive data.  The best solution to this problem is to use  a  better
       authorization  mechanism  than  is  provided  by X.  Given all of these
       caveats, a simple mechanism exists for  protecting  keyboard  input  in
       xterm.

       The  xterm  menu  (see  MENUS  above)  contains a Secure Keyboard entry
       which, when enabled, attempts to ensure  that  all  keyboard  input  is
       directed only to xterm (using the GrabKeyboard protocol request).  When
       an application prompts you for a password (or  other  sensitive  data),
       you  can  enable  Secure Keyboard using the menu, type in the data, and
       then disable Secure Keyboard using the menu again.  This  ensures  that
       you  know  which window is accepting your keystrokes.  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
       displays a prompt before asking for the password, it is safest to enter
       secure mode before the prompt gets displayed, and to make sure that the
       prompt gets displayed correctly (in the new colors),  to  minimize  the
       probability of spoofing.  You can also bring up the menu again and make
       sure that a check mark appears next to the entry.

       Secure Keyboard mode will  be  disabled  automatically  if  your  xterm
       window  becomes iconified (or otherwise unmapped), or if you start up a
       reparenting window manager (that places a title bar or other decoration
       around  the  window) while in Secure Keyboard mode.  (This is a feature
       of the X  protocol  not  easily  overcome.)   When  this  happens,  the
       foreground  and  background  colors  will be switched back and the bell
       will sound in warning.

CHARACTER CLASSES

       Clicking the left pointer button twice  in  rapid  succession  (double-
       clicking) causes all characters of the same class (e.g., letters, white
       space, punctuation) to be selected as a "word".  Since different people
       have  different  preferences  for what should be selected (for example,
       should filenames be selected as a whole or only the separate subnames),
       the  default mapping can be overridden through the use of the charClass
       (class CharClass) resource.

       This resource is a series of comma-separated of range:value pairs.  The
       range is either a single number or low-high in the range of 0 to 65535,
       corresponding to the code for the character or characters  to  be  set.
       The  value  is arbitrary, although the default table uses the character
       number of the first character occurring in the set.  When not in  UTF-8
       mode, only the first 256 bytes of this table will be used.

       The default table starts as follows -

           static int charClass[256] = {
           /* NUL  SOH  STX  ETX  EOT  ENQ  ACK  BEL */
               32,   1,   1,   1,   1,   1,   1,   1,
           /*  BS   HT   NL   VT   NP   CR   SO   SI */
                1,  32,   1,   1,   1,   1,   1,   1,
           /* DLE  DC1  DC2  DC3  DC4  NAK  SYN  ETB */
                1,   1,   1,   1,   1,   1,   1,   1,
           /* CAN   EM  SUB  ESC   FS   GS   RS   US */
                1,   1,   1,   1,   1,   1,   1,   1,
           /*  SP    !    "    #    $    %    &    ' */
               32,  33,  34,  35,  36,  37,  38,  39,
           /*   (    )    *    +    ,    -    .    / */
               40,  41,  42,  43,  44,  45,  46,  47,
           /*   0    1    2    3    4    5    6    7 */
               48,  48,  48,  48,  48,  48,  48,  48,
           /*   8    9    :    ;    <    =    >    ? */
               48,  48,  58,  59,  60,  61,  62,  63,
           /*   @    A    B    C    D    E    F    G */
               64,  48,  48,  48,  48,  48,  48,  48,
           /*   H    I    J    K    L    M    N    O */
               48,  48,  48,  48,  48,  48,  48,  48,
           /*   P    Q    R    S    T    U    V    W */
               48,  48,  48,  48,  48,  48,  48,  48,

       For example, the string "33:48,37:48,45-47:48,38:48" indicates that the
       exclamation mark, percent sign,  dash,  period,  slash,  and  ampersand
       characters  should  be  treated the same way as characters and numbers.
       This is useful for cutting and pasting electronic mailing addresses and
       filenames.

ACTIONS

       It  is  possible  to  rebind  keys  (or sequences of keys) to arbitrary
       strings for input, by changing the translations resources for the vt100
       or  tek4014  widgets.   Changing  the  translations resource for events
       other than key and button  events  is  not  expected,  and  will  cause
       unpredictable  behavior.   The  following  actions are provided for use
       within the vt100 or tek4014 translations resources:

       allow-color-ops(on/off/toggle)
               This action set 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  set  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 set or toggles the allowSendEvents resource and  is
               also invoked by the allowsends entry in mainMenu.

       allow-tcap-ops(on/off/toggle)
               This  action  set  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 set 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  set 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 eightBitInput 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.

       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
               feature   partially   emulates   the   behavior   of   "dynamic
               abbreviation" expansion in Emacs (bound there to M-/).  Here is
               a resource setting for xterm which will do the same thing:

                   *VT100*translations:    #override \n\
                           Meta <KeyPress> /:dabbrev-expand()

       deiconify()
               Changes the window state back to normal, if it was iconified.

       delete-is-del()
               This action toggles the state of the deleteIsDEL resource.

       dired-button()
               Handles  a  button  event  (other  than  press  and release) by
               echoing the event's position (i.e., character line and  column)
               in the following format:

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

       iconify()
               Iconifies the window.

       hard-reset()
               This action resets the scrolling region, tabs, window size, and
               cursor keys and clears the screen.  It is also invoked from the
               hardreset entry in vtMenu.

       ignore()
               This  action  ignores  the event but checks for special pointer
               position escape sequences.

       insert()
               This action inserts the character or string associated with the
               key that was pressed.

       insert-eight-bit()
               This   action  inserts  an  eight-bit  (Meta)  version  of  the
               character or string associated with the key that  was  pressed.
               This  only  applies  to  single-byte  values.  The exact action
               depends  on  the  value  of   the   metaSendsEscape   and   the
               eightBitInput   resources.   The  metaSendsEscape  resource  is
               tested first.

               The term "eight-bit" is misleading: xterm checks if  the  key's
               value  is  less  than 128.  If so, xterm adds 128 to the value,
               setting its eighth bit.  Otherwise  xterm  sends  an  ESC  byte
               before  the key.  In other applications' documentation, that is
               referred to as a "meta key".

       insert-selection(sourcename [, ...])
               This action inserts  the  string  found  in  the  selection  or
               cutbuffer  indicated by sourcename.  Sources are checked in the
               order  given  (case  is  significant)  until  one   is   found.
               Commonly-used   selections  include:  PRIMARY,  SECONDARY,  and
               CLIPBOARD.  Cut buffers are typically named CUT_BUFFER0 through
               CUT_BUFFER7.

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

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

       keymap(name)
               This  action  dynamically defines a new translation table whose
               resource  name  is  name  with  the  suffix  Keymap  (case   is
               significant).   The name None restores the original translation
               table.

       larger-vt-font()
               Set the font  to  the  next  larger  one,  based  on  the  font
               dimensions.  See also set-vt-font().

       load-vt-fonts(name[,class])
               Load fontnames from the given subresource name and class.  That
               is, load the "*VT100.name.font", resource as "*VT100.font" etc.
               If no name is given, the original set of fontnames is restored.

               Unlike set-vt-font(), this does  not  affect  the  escape-  and
               select-fonts, since those are not based on resource values.  It
               does affect the fonts loosely  organized  under  the  "Default"
               menu    entry,   including   font,   boldFont,   wideFont   and
               wideBoldFont.

       maximize()
               Resizes the window to fill the screen.

       meta-sends-escape()
               This action toggles the state of the metaSendsEscape  resource.

       popup-menu(menuname)
               This  action  displays  the  specified popup menu.  Valid names
               (case is significant) include:  mainMenu, vtMenu, fontMenu, and
               tekMenu.

       print(printer-flags)
               This  action prints the window and is also invoked by the print
               entry in mainMenu.

               The  action  accepts  optional  parameters,  which  temporarily
               override  resource  settings.  The parameter values are matched
               ignoring case:

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

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

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

               NewLine
                    a newline will be  sent  at  the  end  of  the  last  line
                    printed,  and  each  line  will  be  limited  (by adding a
                    newline) to the  screen  width  (i.e.,  printerNewLine  is
                    ``true'').

               noAttrs
                    the    page   is   printed   without   attributes   (i.e.,
                    printAttributes is ``0'').

               monoAttrs
                    the page is printed  with  monochrome  (vt220)  attributes
                    (i.e., printAttributes is ``1'').

               colorAttrs
                    the  page  is  printed  with  ANSI color attributes (i.e.,
                    printAttributes is ``2'').

       print-everything(printer-flags)
               This action sends the entire text history, in addition  to  the
               text   currently   visible,   to   the  program  given  in  the
               printerCommand  resource.   It   allows   the   same   optional
               parameters  as  the  print  action.   With  a  suitable printer
               command, the action can be used to load the text history in  an
               editor.

       print-redir()
               This  action  toggles  the  printerControlMode between 0 and 2.
               The corresponding popup menu entry is useful for switching  the
               printer off if you happen to change your mind after deciding to
               print random binary files on the terminal.

       quit()  This action sends a SIGHUP to the subprogram and exits.  It  is
               also invoked by the quit entry in mainMenu.

       readline-button()
               Supports  the  optional  readline  feature  by echoing repeated
               cursor forward or backward control sequences on button  release
               event,  to  request that the host application update its notion
               of the cursor's position to match the button event.

       redraw()
               This action redraws the window  and  is  also  invoked  by  the
               redraw entry in mainMenu.

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

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

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

               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 toggles internal state which  tells  xterm  whether
               Scroll Lock is active, subject to the allowScrollLock 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.

       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
               selection, without affecting the selection mode.

       select-start()

                      xfontsel(1)) indicated by the second action argument.

               If   xterm   is  configured  to  support  wide  characters,  an
               additional two optional parameters are  recognized  for  the  e
               argument: wide font and wide bold font.

       smaller-vt-font()
               Set  the  font  to  the  next  smaller  one,  based on the font

               This action resets the scrolling region  and  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
               selection is extended to the current pointer location.

       start-cursor-extend()
               This  action  is  similar  to  select-extend  except  that  the
               selection 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
               whitespace  or  non-alphanumeric  characters.   If  the  string
               argument begins with the characters "0x", it is interpreted  as
               a hex character constant.

       tek-copy()
               This  action  copies  the  escape  codes  used  to generate the
               current window contents to a  file  in  the  current  directory
               beginning  with  the  name  COPY.   It is also invoked from the
               tekcopy entry in tekMenu.

       tek-page()
               This action clears the Tektronix window and is also invoked  by

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

       vi-button()
               Handles a button  event  (other  than  press  and  release)  by
               echoing  a  control  sequence  computed  from  the event's line
               number in the screen relative to the current line:

                       ESC ^P
               or
                       ESC ^N

               according to whether the event is before, or after the  current
               line,  respectively.   The ^N (or ^P) is repeated once for each
               line that the event differs from the current line.  The control
               sequence  is  omitted  altogether if the button event is on the
               current line.

       visual-bell()
               This action flashes the window quickly.

       The Tektronix window also has the following action:

       gin-press(l/L/m/M/r/R)
               This action sends the indicated graphics input code.

       The default bindings in the VT102 window use the SELECT token, which is
       set by the selectToClipboard resource:

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

       Here is an example which uses  shifted  select/paste  to  copy  to  the
       clipboard,  and  unshifted  select/paste for the primary selection.  In
       each case, a (different) cut buffer is also a target or source  of  the
       select/paste  operation.  It is important to remember however, that cut
       buffers store data in ISO-8859-1 encoding, while selections  can  store
       data  in  a  variety  of  formats  and encodings.  While xterm owns the
       selection, it highlights it.  When it loses the selection,  it  removes
       the  corresponding  highlight.   But  you  can  still  paste  from  the
       corresponding cut buffer.

           *VT100*translations:    #override \n\
               ~Shift~Ctrl<Btn2Up>: insert-selection(PRIMARY, CUT_BUFFER0) \n\
               Shift~Ctrl<Btn2Up>:  insert-selection(CLIPBOARD, CUT_BUFFER1) \n\
               ~Shift<BtnUp>:       select-end(PRIMARY, CUT_BUFFER0) \n\
               Shift<BtnUp>:        select-end(CLIPBOARD, CUT_BUFFER1)

       Below is a sample how of the keymap() action is  used  to  add  special
       keys for entering commonly-typed works:

           *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)

       Some  people  prefer  using  the  left  pointer button for dragging the
       scrollbar thumb.  That  can  be  setup  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

       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
       Tektronix terminals,  or  from  more  widely  used  standards  such  as
       ISO-6429.

ENVIRONMENT

       Xterm sets several environment variables:

       DISPLAY
            is  the  display name, pointing to the X server (see DISPLAY NAMES
            in X(7)).

       TERM is set according to the termcap (or terminfo) entry  which  it  is
            using as a reference.

       WINDOWID
            is set to the X window id number of the xterm window.

       XTERM_LOCALE
            shows  the  locale which was used by xterm on startup.  Some shell
            initialization scripts may set a different locale.

       XTERM_SHELL
            is set to the pathname of the program which is  invoked.   Usually
            that  is  a  shell  program,  e.g.,  /bin/sh.   Since  it  is  not
            necessarily a shell program however, it is distinct from  "SHELL".

       XTERM_VERSION
            is  set  to  the string displayed by the -version option.  That is
            normally an identifier for the X Window libraries  used  to  build
            xterm, followed by xterm's patch number in parenthesis.  The patch
            number is  also  part  of  the  response  to  a  Secondary  Device
            Attributes (DA) control sequence (see Xterm Control Sequences).

       Depending  on  your  system  configuration,  xterm  may  also  set  the
       following:

       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 the shell name as the optional parameter.

       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.

       /var/run/utmp
            the system logfile, which records user logins.

       /var/log/wtmp
            the system logfile, which records user logins and logouts.

       /etc/X11/app-defaults/XTerm
            the xterm default application resources.

       /etc/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 /etc/X11/app-defaults/XTerm.  If you do not  do  this,
            xterm uses its compiled-in default resource settings for colors.

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.

       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.
