SYNOPSIS
xterm [-toolkitoption ...] [-option ...]
DESCRIPTION
The xterm program is a terminal emulator for the X Window System. It
provides DEC VT102/VT220 (VTxxx) and Tektronix 4014 compatible termi-
nals 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), Tek-
tronix graphics will be restricted to the largest box with a 4014's
aspect ratio that will fit in the window. This box is located in the
upper left area of the window.
Although both windows may be displayed at the same time, one of them is
considered the ``active'' window for receiving keyboard input and ter-
minal 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 autore-
peat. Double-size characters are displayed properly if your font
server supports scalable fonts. Blinking characters are partially
implemented; the emulation is functional but does not have the appear-
ance of a real VT102. 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'' and ``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 con-
trol through a set of escape sequences different from the standard
VT102 escape sequences. (See the Xterm Control Sequences document.)
The Tektronix 4014 emulation is also fairly good. It supports 12-bit
graphics addressing, scaled to the window size. Four different font
sizes and five different lines types are supported. There is no write-
through or defocused mode support. The Tektronix text and graphics
commands are recorded internally by xterm and may be written to a file
by sending the COPY escape sequence (or through the Tektronix menu; see
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 alter-
nate screen for editing and to restore the screen on exit. A popup
menu entry makes it simple to switch between the normal and alternate
screens for cut and paste.
In either VT102 or Tektronix mode, there are escape sequences to change
the name of the windows. Additionally, in VT102 mode, xterm implements
the window-manipulation control sequences from dtterm, such as resizing
the window, setting its location on the screen.
Xterm allows character-based applications to receive mouse events (cur-
rently button-press and release events, and button-motion events) as
keyboard control sequences. See Xterm Control Sequences for details.
OPTIONS
The xterm terminal emulator accepts all of the standard X Toolkit com-
mand line options as well as the following (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. The message is written to the standard error.
The other options are used to control the appearance and behavior. Not
all options are necessarily configured into your copy of xterm.
-132 Normally, the VT102 DECCOLM escape sequence that switches
between 80 and 132 column mode is ignored. This option causes
the DECCOLM escape sequence to be recognized, and the xterm
window will resize appropriately.
-ah This option indicates that xterm should always highlight the
text cursor. By default, xterm will display a hollow text cur-
sor whenever the focus is lost or the pointer leaves the win-
dow.
+ah This option indicates that xterm should do text cursor high-
lighting based on focus.
allowed.
-b number
This option specifies the size of the inner border (the dis-
tance between the outer edge of the characters and the window
border) in pixels. 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
time text cursor is off when blinking
-bcn milliseconds
time text cursor is on when blinking
-bdc Set the vt100 resource colorBDMode to FALSE, disabling the dis-
play of characters with bold attribute as color
+bdc Set the vt100 resource colorBDMode to TRUE, enabling the dis-
play of characters with bold attribute as color rather than
bold
-cb Set the vt100 resource cutToBeginningOfLine to FALSE.
+cb Set the vt100 resource cutToBeginningOfLine to TRUE.
-cc characterclassrange:value[,...]
This sets classes indicated by the given ranges for using in
selecting by words. See the section specifying character
classes.
-cjk_width
Set the cjkWidth resource to ``true''. When turned on, charac-
ters with East Asian Ambiguous (A) category in UTR 11 have a
column width of 2. Othrwise, they have a column width of 1.
This may be useful for some legacy CJK text terminal-based pro-
grams assuming box drawings and others to have a column width
of 2. It also has to 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
-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.
-cu This option indicates that xterm should work around a bug in
the more(1) program that causes it to incorrectly display lines
that are exactly the width of the window and are followed by a
line beginning with a tab (the leading tabs are not displayed).
This option is so named because it was originally thought to be
a bug in the curses(3x) cursor motion package.
+cu This option indicates that xterm should not work around the
more(1) bug mentioned above.
-dc This option disables the escape sequence to change dynamic col-
ors: the vt100 foreground and background colors, the text cur-
sor color, the mouse cursor foreground and background colors,
the Tektronix emulator foreground and background colors, and
highlight color.
+dc This option enables the escape sequence to change dynamic col-
ors.
-e program [ arguments ... ]
This option specifies the program (and its command line argu-
ments) to be run in the xterm window. It also sets the window
title and icon name to be the basename of the program being
executed if neither -T nor -n are given on the command line.
This must be the last option on the command line.
-en encoding
This option determines the encoding on which xterm runs. It
corresponds to 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. This font must be the same height and width as the nor-
mal font. If only one of the normal or bold fonts is speci-
fied, it will be used as the normal font and the bold font will
be produced by overstriking this font. The default is to do
overstriking of the normal font. See also the discussion of
boldFont and boldMode 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.
-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 dou-
blewidth 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
doublewidth 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
This option specifies the color to use for the background of
selected or otherwise highlighted text. If not specified,
reverse video is used.
-hf This option indicates that HP Function Key escape codes should
be generated for function keys.
+hf This option indicates that HP Function Key escape codes should
not be generated for function keys.
-hold Turn on the hold resource, i.e., xterm will not immediately
destroy its window when the shell command completes. It will
wait until you use the window manager to destroy/kill the win-
dow, or if you use the menu entries that send a signal, e.g.,
HUP or KILL.
+hold Turn off the hold resource, i.e., xterm will immediately
destroy its window when the shell command completes.
-ie Turn on the ptyInitialErase resource, i.e., use the pseudo-ter-
minal's sense of the stty erase value.
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 con-
trol characters (code 128-159) to treat them as printable.
+k8 This option resets the allowC1Printable resource.
-l Turn logging on. Normally logging is not supported, due to
security concerns. Some versions of xterm may have logging
enabled. The logfile is written to the directory from which
xterm is invoked. The filename is generated, of the form
XtermLog.XXXXXX
or
Xterm.log.hostname.yyyy.mm.dd.hh.mm.ss.XXXXXX
depending on how xterm was built.
+l Turn logging off.
-lc Turn on support of various encodings according to the users'
locale setting, i.e., LC_ALL, LC_CTYPE, or LANG environment
variables. This is achieved by turning on UTF-8 mode and by
invoking luit for conversion between locale encodings and
UTF-8. (luit is not invoked in UTF-8 locales.) This corre-
sponds to the locale resource.
The actual list of encodings which are supported is determined
by luit. Consult the luit manual page for further details.
See also the discussion of the -u8 option which supports UTF-8
locales.
+lc Turn off support of automatic selection of locale encodings.
Conventional 8bit mode or, in UTF-8 locales or with -u8 option,
UTF-8 mode will be used.
-lcc path
File name for the encoding converter from/to locale encodings
and UTF-8 which is used with -lc option or locale resource.
This corresponds to the localeFilter resource.
start the given command after whatever it does when it is a
login shell - the user's shell of choice need not be a Bourne
shell after all. Also, xterm -e is supposed to provide a con-
sistent functionality for other applications that need to start
text-mode programs in a window, and if loginShell were not
ignored, the result of ~/.profile might interfere with that.
If you do want the effect of -ls and -a simultaneously, you may
get away with something like
xterm -e /bin/bash -l -c "my command here"
Finally, -ls is not completely ignored, because xterm -ls -e
does write a /etc/wtmp entry (if configured to do so), whereas
xterm -e does not.
+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. This option can
be turned on and off from the ``VT Options'' menu.
+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.
-ms color
This option specifies the color to be used for the pointer cur-
sor. The default is to use the foreground color.
-nb number
This option specifies the number of characters from the right
end of a line at which the margin bell, if enabled, will ring.
The default is 10.
-nul This option disables the display of underlining.
+nul This option enables the display of underlining.
-pc This option enables the PC-style use of bold colors (see bold-
Colors resource).
+pc This option disables the PC-style use of bold colors.
-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.
-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 auto-
matically reposition the screen to the bottom of the scrolling
region. This option can be turned on and off from the ``VT
Options'' menu.
+si This option indicates that output to a window should cause it
to scroll to the bottom.
-sk This option indicates that pressing a key while using the
+sm This option indicates that xterm should not set up session man-
ager callbacks.
-sp This option indicates that Sun/PC keyboard should be assumed,
providing mapping for keypad `+' to `,', and CTRL-F1 to F13,
CTRL-F2 to F14, etc.
+sp This option indicates that the standard escape codes should be
generated for keypad and function keys.
-t This option indicates that xterm should start in Tektronix
mode, rather than in VT102 mode. Switching between the two
windows is done using the ``Options'' menus. Termcap(5)
entries that work with xterm ``tek4014,'' ``tek4015,''
``tek4012'', ``tek4013'' and ``tek4010,'' and ``dumb.'' xterm
automatically searches the termcap file in this order for these
entries and then sets the ``TERM'' and the ``TERMCAP'' environ-
ment variables.
+t This option indicates that xterm should start in VT102 mode.
-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 func-
tions, similar to the stty program. Allowable keywords
include: intr, quit, erase, kill, eof, eol, swtch, start, stop,
brk, susp, dsusp, rprnt, flush, weras, and lnext. Control
characters may be specified as ^char (e.g., ^c or ^u) and ^?
may be used to indicate delete (127).
-tn name
This option specifies the name of the terminal type to be set
in the TERM environment variable. This terminal type must
exist in the termcap(5) database and should have li# and co#
entries.
-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
attribute as color 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 show 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 immedi-
ately, showing you which window has the output. (A similar
feature was in x10 xterm.)
-C This option indicates that this window should receive console
output. This is not supported on all systems. To obtain con-
sole output, you must be the owner of the console device, and
you must have read and write permission for it. If you are
running X under xdm on the console screen you may need to have
the session startup and reset programs explicitly change the
ownership of the console device in order to get this option to
work.
-Sccn This option allows xterm to be used as an input and output
channel for an existing program and is sometimes used in spe-
cialized applications. The option value specifies the last few
letters of the name of a pseudo-terminal to use in slave mode,
Tektronix window. It is shorthand for specifying the ``*tekGe-
ometry'' resource.
#geom This option specifies the preferred position of the icon win-
dow. It is shorthand for specifying the ``*iconGeometry''
resource.
-T string
This option specifies the title for xterm's windows. It is
equivalent to -title.
-n string
This option specifies the icon name for xterm's windows. It is
shorthand for specifying the ``*iconName'' resource. Note that
this is not the same as the toolkit option -name (see below).
The default icon name is the application name.
-r This option indicates that reverse video should be simulated by
swapping the foreground and background colors. It is equiva-
lent to -rv.
-w number
This option specifies the width in pixels of the border sur-
rounding the window. It is equivalent to -borderwidth or -bw.
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 default is ``black.''
-bg color
This option specifies the color to use for the background of
the window. The default is ``white.''
-bw number
This option specifies the width in pixels of the border sur-
rounding the 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 default is ``black.''
-fn font
This option specifies the font to be used for displaying normal
text. The default is fixed.
-geometry geometry
+rv Disable the simulation of reverse video by swapping foreground
and background colors.
-title string
This option specifies the window title string, which may be
displayed by window managers if the user so chooses. The
default title is the command line specified after the -e
option, if any, otherwise the application name.
-xrm resourcestring
This option specifies a resource string to be used. This is
especially useful for setting resources that do not have sepa-
rate command line options.
RESOURCES
The program understands all of the core X Toolkit resource names and
classes. Application specific resources (e.g., "XTerm.NAME") follow:
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 fea-
ture.
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.
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.
messages (class Messages)
Specifies whether write access to the terminal is allowed ini-
tially. See mesg(1). The default is ``true''.
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''.
sessionMgt (class SessionMgt)
If the value of this resource is ``true'', xterm sets up ses-
sion 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.
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 sunKey-
board set to ``false''), xterm uses PC-style bindings for the
function keys and keypad.
termName (class TermName)
Specifies the terminal type name to be set in the TERM environ-
ment variable.
title (class Title)
Specifies a string that may be used by the window manager when
displaying this application.
ttyModes (class TtyModes)
Specifies a string containing terminal setting keywords and the
characters to which they may be bound. Allowable keywords
include: intr, quit, erase, kill, eof, eol, swtch, start, stop,
brk, susp, dsusp, rprnt, flush, weras, lnext and status. Con-
trol 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 set-
tings without having to do an stty every time an xterm is
started. Note, however, that the stty program on a given host
may use different keywords; xterm's table is builtin.
zIconBeep (class ZIconBeep)
Same as -ziconbeep command line argument. If the value of this
resource is non-zero, xterms that produce output while iconi-
fied will cause an XBell sound at the given volume and have
"***" prepended to their icon titles. Most window managers
will detect this change immediately, showing you which window
has the output. (A similar feature was in x10 xterm.) The
default is ``false.''
The following resources are specified as part of the vt100 widget
(class VT100): These are specified by patterns such as
"XTerm.vt100.NAME":
activeIcon (class ActiveIcon)
Specifies whether or not active icon windows are to be used
when the xterm window is iconified, if this feature is compiled
into xterm. The active icon is a miniature representation of
the content of the window and will update as the content
changes. Not all window managers necessarily support applica-
tion icon windows. Some window managers will allow you to
enter keystrokes into the active icon window. The default is
``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.''
allowSendEvents (class AllowSendEvents)
Specifies whether or not synthetic key and button events (gen-
erated using the X protocol SendEvent request) should be inter-
preted or discarded. The default is ``false'' meaning they are
discarded. Note that allowing such events creates a very large
security hole. The default is ``false.''
allowWindowOps (class AllowWindowOps)
Specifies whether extended window control sequences (as used in
dtterm) for should be allowed. The default is ``true.''
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.
alwaysHighlight (class AlwaysHighlight)
Specifies whether or not xterm should always display a high-
lighted text cursor. By default (if this resource is false), a
hollow text cursor is displayed whenever the pointer moves out
of the window or the window loses the input focus. The default
is ``false.''
autoWrap (class AutoWrap)
Specifies whether or not auto-wraparound should be enabled.
The default is ``true.''
awaitInput (class AwaitInput)
Specifies whether or not the xterm uses a 50 millisecond time-
out to await input (i.e., to support the Xaw3d arrow scroll-
bar). The default is ``false.''
backarrowKey (class BackarrowKey)
Specifies whether the backarrow key transmits a backspace (8)
or delete (127) character. This corresponds to the DECBKM con-
trol sequence. 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 ``white.''
bellSuppressTime (class BellSuppressTime)
Number of milliseconds after a bell command is sent during
which additional bells will be suppressed. Default is 200. If
set non-zero, additional bells will also be suppressed until
the server reports that processing of the first bell has been
completed; this feature is most useful with the visible bell.
boldColors (class ColorMode)
Specifies whether to combine bold attribute with colors like
the IBM PC, i.e., map colors 0 through 7 to colors 8 through
15. These normally are the brighter versions of the first 8
colors, hence bold. The default is ``true.''
boldFont (class BoldFont)
Specifies the name of the bold font to use instead of over-
striking. There is no default for this resource.
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. It attempts to match a bold font for the other
font selections (font1 through font6). If the normal and bold
fonts are distinct, this resource has no effect. The default
is ``true.''
Although xterm attempts to match a bold font for other font
selections, the font server may not cooperate. Since X11R6,
bitmap fonts have been scaled. The font server claims to pro-
vide the bold font that xterm requests, but the result is not
tion for "misc".
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.
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.''
c132 (class C132)
Specifies whether or not the VT102 DECCOLM escape sequence
should be honored. The default is ``false.''
cutNewline (class CutNewline)
If ``false'', triple clicking to select a line does not include
the Newline at the end of the line. If ``true'', the Newline
is selected. The default is ``true.''
cutToBeginningOfLine (class CutToBeginningOfLine)
If ``false'', triple clicking to select a line selects only
from the current word forward. If ``true'', the entire line is
selected. The default is ``true.''
cacheDoublesize (class CacheDoublesize)
Specifies the maximum number of double-sized fonts which are
cached by xterm. The default (8) may be too large for some X
terminals with limited memory. Set this to zero to disable
doublesize 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
colorMode (class ColorMode)
Specifies whether or not recognition of ANSI (ISO 6429) color
change escape sequences should be enabled. The default is
``true.''
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.''
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.''
colorRVMode (class ColorAttrMode)
Specifies whether characters with the reverse attribute should
be displayed in color. Note that setting colorMode off dis-
ables all colors, including this. The default is ``false.''
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.''
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,
DodgerBlue1, 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)
respectively, gray30, red, green, yellow, SteelBlue1, 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.
colorBD (class ColorBD)
This specifies the color to use to display bold characters if
the ``colorBDMode'' resource is enabled. The default is
``XtDefaultForeground.''
colorBL (class ColorBL)
This specifies the color to use to display blink characters if
the ``colorBLMode'' resource is enabled. The default is
``XtDefaultForeground.''
colorRV (class ColorRV)
This specifies the color to use to display reverse characters
if the ``colorRVMode'' resource is enabled. The default is
``XtDefaultForeground.''
colorUL (class ColorUL)
This specifies the color to use to display underlined charac-
ters if the ``colorULMode'' resource is enabled. The default
is ``XtDefaultForeground.''
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.
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
``black.''
cursorOffTime (class CursorOffTime)
Specifies the duration of the "off" part of the cursor blink
cycle-time in milliseconds. The default is 300.
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.
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 input from the keyboard are pre-
sented as a single character with the eighth bit turned on.
The terminal is put into 8-bit mode. If ``false'', Meta char-
acters are converted into a two-character sequence with the
character itself preceded by ESC. The terminal is put into
7-bit mode. The metaSendsEscape resource may override this.
The default is ``true.''
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.
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. If not specified, or if there is no match
for both normal and bold fonts, xterm uses the font and related
resources.
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.''
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.
font1 (class Font1)
Specifies the name of the first alternative font.
font2 (class Font2)
Specifies the name of the second alternative font.
Specifies whether xterm should attempt to use font scaling to
draw doublesize characters. Some older font servers cannot do
this properly, will return misleading font metrics. The
default is ``true''. If disabled, xterm will simulate double-
size characters by drawing normal characters with spaces
between them.
forceBoxChars (class Boolean)
Specifies whether xterm should assume the normal and bold fonts
have VT100 line-drawing characters. If ``false'', xterm will
check for missing characters in the 1-31 cells and make line-
drawing characters directly. The default is ``false.''
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 ``black.''
freeBoldBox (class Boolean)
Specifies whether xterm should assume the bounding boxes for
normal and bold fonts are compatible. If ``false'', xterm com-
pares them and will reject choices of bold fonts that do not
match the size of the normal font. The default is ``false'',
which means that the comparison is performed.
geometry (class Geometry)
Specifies the preferred size and position of the VT102 window.
There is no default for this resource.
highlightSelection (class HighlightSelection)
If ``false'', selecting with the mouse highlights all positions
on the screen between the beginning of the selection and the
current position. If ``true'', xterm highlights only the posi-
tions that contain text that can be selected. The default is
``false.''
Depending on the way your applications write to the screen,
there may be trailing blanks on a line. Xterm stores data as
it is shown on the screen. Erasing the display changes the
internal state of each cell so it is not considered a blank for
the purpose of selection. Blanks written since the last erase
are selectable. If you do not wish to have trailing blanks in
a selection, use the trimSelection resource.
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.''
iconFont (class IconFont)
Specifies the font for the miniature active icon window, if
this feature is compiled into xterm. The default is "nil2".
internalBorder (class BorderWidth)
Specifies the number of pixels between the characters and the
window border. The default is 2.
jumpScroll (class JumpScroll)
Specifies whether or not jump scroll should be used. 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.
keymapNAME (class KeymapNAME)
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.
no xterm will use conventional 8bit mode or UTF-8 mode accord-
ing to utf8 resource or -u8 option.
Any other value, e.g., ``UTF-8'' or ``ISO8859-2'', is assumed
to be an encoding name; luit will be invoked to support the
encoding. The actual list of supported encodings depends on
luit. The default is ``medium''.
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 configu-
ration.
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 run when the user
types near the right margin. The default is ``false.''
metaSendsEscape (class MetaSendsEscape)
If ``true'', Meta characters 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.''
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. 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. Set it to 3 to mark the sequence with a
'>' to hint that it is private. The default is ``2''.
multiClickTime (class MultiClickTime)
Specifies the maximum time in milliseconds between multi-click
select events. The default is 250 milliseconds.
multiScroll (class MultiScroll)
Specifies whether or not scrolling should be done asyn-
chronously. The default is ``false.''
nMarginBell (class Column)
Specifies the number of characters from the right margin at
which the margin bell should be rung, when enabled.
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)
Specifies the name of the shape of the pointer. The default is
``xterm.''
popOnBell (class PopOnBell)
Specifies whether the window whould be raised when Control-G is
received. The default is ``false.''
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 com-
mand. The default is ``false.''
printerCommand (class PrinterCommand)
Specifies a shell command to which xterm will open a pipe when
the first MC (Media Copy) command is initiated. The default is
``lpr.'' 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 mar-
gins (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.''
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
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.''
scrollKey (class ScrollCond)
Specifies whether or not pressing a key should automatically
cause the scrollbar to go to the bottom of the scrolling
region. The default is ``false.''
scrollLines (class ScrollLines)
Specifies the number of lines that the scroll-back and scroll-
forw actions should use as a default. The default value is 1.
scrollTtyOutput (class ScrollCond)
Specifies whether or not output to the terminal should automat-
ically cause the scrollbar to go to the bottom of the scrolling
region. The default is ``true.''
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.''
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 win-
dow. There is no default for this resource.
tekInhibit (class TekInhibit)
Specifies whether or not the escape sequence to enter Tektronix
mode should be ignored. The default is ``false.''
tekSmall (class TekSmall)
Specifies whether or not the Tektronix mode window should start
in its smallest size if no explicit geometry is given. This is
useful when running xterm on displays with small screens. The
default is ``false.''
tekStartup (class TekStartup)
Specifies whether or not xterm should start up in Tektronix
Specifies whether xterm should scroll to a new page when pro-
cessing the ti termcap entry, i.e., the private modes 47, 1047
or 1049. This is only in effect if titeInhibit is ``true'',
because the intent of this option is to provide a picture of
the full-screen application's display on the scrollback without
wiping out the text that would be shown before the application
was initialized. The default for this resource is ``false.''
translations (class Translations)
Specifies the key and button bindings for menus, selections,
``programmed strings,'' etc. See the ACTIONS section.
trimSelection (class TrimSelection)
If you set highlightSelection, you can see the text which is
selected, including any trailing spaces. Clearing the screen
(or a line) resets it to a state containing no spaces. Some
lines may contain trailing spaces when an application writes
them to the screen. However, you may not wish to paste lines
with trailing spaces. If this resource is true, xterm will
trim trailing spaces from text which is selected. It does not
affect spaces which result in a wrapped line, nor will it trim
the trailing newline from your selection. The default is
``false.''
underLine (class UnderLine)
This specifies whether or not text with the underline attribute
should be underlined. It may be desirable to disable underlin-
ing when color is being used for the underline attribute. The
default is ``true.''
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. When set via a resource, xterm cannot be switched
via control sequences out of UTF-8 mode. The default is ``0''
(off). Any other value will turn on UTF-8 mode. See the
locale resource for non-UTF-8 locales.
utf8Fonts (class Utf8Fonts)
See the discussion of the locale resource.
veryBoldColors (class VeryBoldColors)
Specifies whether to combine video attributes with colors spec-
ified by colorBD, colorBL and colorUL. The resource value is
the sum of values for each attribute: 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.''
wide as the font that will be used to draw bold text. If no
doublewidth font is found, it will improvise, by stretching the
bold font.
wideChars (class WideChars)
Specifies if xterm should respond to control sequences that
process 16-bit characters. The default is ``false.''
wideFont (class WideFont)
This option specifies the font to be used for displaying wide
text. By default, it will attempt to use a font twice as wide
as the font that will be used to draw normal text. If no dou-
blewidth 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.
The following resources are specified as part of the tek4014 widget
(class Tek4014). These are specified by patterns such as
"XTerm.tek4014.NAME":
font2 (class Font)
Specifies font number 2 to use in the Tektronix window.
font3 (class Font)
Specifies font number 3 to use in the Tektronix window.
fontLarge (class Font)
Specifies the large font to use in the Tektronix window.
fontSmall (class Font)
Specifies the small font to use in the Tektronix window.
ginTerminator (class GinTerminator)
Specifies what character(s) should follow a GIN report or sta-
tus report. The possibilities are ``none,'' which sends no
terminating characters, ``CRonly,'' which sends CR, and
``CR&EOT,'' which sends both CR and EOT. The default is
``none.''

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.
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
as keyboard input.
Pointer button three (usually right) extends the current selection.
(Without loss of generality, you can swap ``right'' and ``left'' every-
where 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 multi-
ple-click to cycle through them.
By cutting and pasting pieces of text without trailing new lines, you
can take text from several places in different windows and form a com-
mand to the shell, for example, or take output from a program and
insert it into your favorite editor. Since the cut buffer is globally
shared among different applications, you should regard it 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.
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.
Unlike the VT102 window, the Tektronix window does not allow the copy-
ing of text. It does allow Tektronix GIN mode, and in this mode the
cursor will change from an arrow to a cross. Pressing any key will
send that key and the current coordinate of the cross cursor. Pressing
button one, two, or three will return the letters `l', `m', and `r',
respectively. If the `shift' key is pressed when a pointer button is
pressed, the corresponding upper case letter is sent. To distinguish a
pointer button from a key, the high bit of the character is set (but
this is bit is normally stripped unless the terminal mode is RAW; see
tty(4) for details).
MENUS
Xterm has four menus, named mainMenu, vtMenu, fontMenu, and tekMenu.
Each menu pops up under the correct combinations of key and button
presses. Most menus are divided into two section, separated by a hori-
zontal line. The top portion contains various modes that can be
especially useful if the user has accidentally typed CTRL-Z, suspending
the process.
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. In the command section of this menu, the soft reset
entry will reset scroll regions. This can be convenient when some pro-
gram has left the scroll regions set incorrectly (often a problem when
using VMS or TOPS-20). 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.
The fontMenu sets the font used in the VT102 window. In addition to
the default font and a number of alternatives that are set with
resources, the menu offers the font last specified by the Set Font
escape sequence (see the document Xterm Control Sequences) and the cur-
rent selection as a font name (if the PRIMARY selection is owned).
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. The PAGE entry in the command section clears the
Tektronix window.
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, there
is every possibility that someone can run an application that will use
the basic services of the X protocol to snoop on your activities,
potentially capturing a transcript of everything you type at the key-
board. This is of particular concern when you want to type in a pass-
word or other sensitive data. The best solution to this problem is to
use a better authorization mechanism that host-based control, but a
simple mechanism exists for protecting keyboard input in xterm.
The xterm menu (see MENUS above) contains a Secure Keyboard entry
which, when enabled, ensures that all keyboard input is directed only
to xterm (using the GrabKeyboard protocol request). When an applica-
tion prompts you for a password (or other sensitive data), you can
enable Secure Keyboard using the menu, type in the data, and then dis-
able Secure Keyboard using the menu again. Only one X client at a time
can secure the keyboard, so when you attempt to enable Secure Keyboard
it may fail. In this case, the bell will sound. If the Secure Key-
board 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
CHARACTER CLASSES
Clicking the middle mouse button twice in rapid succession will cause
all characters of the same class (e.g., letters, white space, punctua-
tion) to be selected. Since different people have different prefer-
ences 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 */

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 for the vt100 or
tek4014 widgets. Changing the translations for events other than key
and button events is not expected, and will cause unpredictable behav-
ior. The following actions are provided for using within the vt100 or
tek4014 translations resources:
allow-send-events(on/off/toggle)
This action set or toggles the allowSendEvents resource and is
also invoked by the allowsends entry in mainMenu.
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.
Iconifies the window.
hard-reset()
This action resets the scrolling region, tabs, window size, and
cursor keys and clears the screen. It is also invoked from the
hardreset entry in vtMenu.
ignore()
This action ignores the event but checks for special pointer
position escape sequences.
insert()
This action inserts the character or string associated with the
key that was pressed.
insert-eight-bit()
This action inserts an eight-bit (Meta) version of the charac-
ter or string associated with the key that was pressed. The
exact action depends on the value of the metaSendsEscape and
the eightBitInput resources.
insert-selection(sourcename [, ...])
This action inserts the string found in the selection or cut-
buffer indicated by sourcename. Sources are checked in the
order given (case is significant) until one is found. Com-
monly-used selections include: PRIMARY, SECONDARY, and CLIP-
BOARD. Cut buffers are typically named CUT_BUFFER0 through
CUT_BUFFER7.
insert-seven-bit()
This action is a synonym for insert()
interpret(control-sequence)
Interpret the given control sequence locally, i.e., without
passing it to the host. This works by inserting the control
sequence at the front of the input buffer. Use "\" to escape
octal digits in the string. Xt does not allow you to put a
null character (i.e., "\000") in the string.
keymap(name)
This action dynamically defines a new translation table whose
resource name is name with the suffix Keymap (case is signifi-
cant). The name None restores the original translation table.
larger-vt-font()
Set the font to the next larger one, based on the font dimen-
sions. See also set-vt-font().
load-vt-fonts(name[,class])
Load fontnames from the given subresource name and class. That
is, load the "*VT100.name.font", resource as "*VT100.font" etc.
If no name is given, the original set of fontnames is restored.
(case is significant) include: mainMenu, vtMenu, fontMenu, and
tekMenu.
print() This action prints the window and is also invoked by the print
entry in mainMenu.
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.
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 visi-
ble.
The count argument indicates the number of units (which may be
page, halfpage, pixel, or line) by which to scroll.
An adjustment can be specified for these values by appending a
"+" or "-" sign followed by a number, e.g., page-2 to specify 2
lines less than a page.
If the third parameter mouse is given, the action is ignored
when mouse reporting is enabled.
scroll-forw(count [,units [,mouse] ])
This action scrolls is similar to scroll-back except that it
scrolls 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.
select-cursor-end(destname [, ...])
This action is similar to select-end except that it should be
used with select-cursor-start.
select-cursor-start()
This action is similar to select-start except that it begins
select-start()
This action begins text selection at the current pointer loca-
tion. See the section on POINTER USAGE for information on mak-
ing selections.
send-signal(signame)
This action sends the signal named by signame to the xterm sub-
process (the shell or program specified with the -e command
line option) and is also invoked by the suspend, continue,
interrupt, hangup, terminate, and kill entries in mainMenu.
Allowable signal names are (case is not significant): tstp (if
supported by the operating system), suspend (same as tstp),
cont (if supported by the operating system), int, hup, term,
quit, alrm, alarm (same as alrm) and kill.
set-allow132(on/off/toggle)
This action toggles the c132 resource and is also invoked from
the allow132 entry in vtMenu.
set-altscreen(on/off/toggle)
This action toggles between the alternate and current screens.

This action toggles the handling Application Cursor Key mode
and is also invoked by the appcursor entry in vtMenu.
set-appkeypad(on/off/toggle)
This action toggles the handling of Application Keypad mode and
is also invoked by the appkeypad entry in vtMenu.
set-autolinefeed(on/off/toggle)
This action toggles automatic insertion of linefeeds and is
also invoked by the autolinefeed entry in vtMenu.

This action toggles the visualBell resource and is also invoked
by the visualbell entry in vtMenu.
set-vt-font(d/1/2/3/4/5/6/e/s [,normalfont [, boldfont]])
This action sets the font or fonts currently being used in the
VT102 window. The first argument is a single character that
specifies the font to be used:
d or D indicate the default font (the font initially used when
xterm was started),
1 through 6 indicate the fonts specified by the font1 through
font6 resources,
e or E indicate the normal and bold fonts that have been set
through escape codes (or specified as the second and
third action arguments, respectively), and
s or S indicate the font selection (as made by programs such as
xfontsel(1)) indicated by the second action argument.
If xterm is configured to support wide characters, an addi-
tional two optional parameters are recognized for the e argu-
ment: wide font and wide bold font.
smaller-vt-font()
Set the font to the next smaller one, based on the font dimen-
sions. See also set-vt-font().
soft-reset()
This action resets the scrolling region and is also invoked
from the softreset entry in vtMenu. The effect is identical to
a soft reset (DECSTR) control sequence.
start-extend()
This action is similar to select-start except that the selec-
tion is extended to the current pointer location.

vi-button()
Handles a button event (other than press and release) by echo-
ing a control sequence computed from the event's line number in
the screen relative to the current line:
ESC ^P
or
ESC ^N
according to whether the event is before, or after the current
line, respectively. The ^N (or ^P) is repeated once for each
line that the event differs from the current line. The control
sequence is omitted altogether if the button event is on the
current line.
visual-bell()
This action flashes the window quickly.
The Tektronix window also has the following action:
gin-press(l/L/m/M/r/R)
This action sends the indicated graphics input code.
The default bindings in the VT102 window are:
Shift <KeyPress> Prior:scroll-back(1,halfpage) \n Shift <KeyPress> Next:scroll-forw(1,halfpage) \n Shift <KeyPress> Select:select-cursor-start() select-cursor-end(PRIMARY, CUT_BUFFER0) \n Shift <KeyPress> Insert:insert-selection(PRIMARY, CUT_BUFFER0) \n Shift~Ctrl <KeyPress> KP_Add:larger-vt-font() \n Shift Ctrl <KeyPress> KP_Add:smaller-vt-font() \n Shift <KeyPress> KP_Subtract:smaller-vt-font() \n ~Meta <KeyPress>:insert-seven-bit() \n Meta <KeyPress>:insert-eight-bit() \n !Ctrl <Btn1Down>:popup-menu(mainMenu) \n !Lock Ctrl <Btn1Down>:popup-menu(mainMenu) \n !Lock Ctrl @Num_Lock <Btn1Down>:popup-menu(mainMenu) \n ! @Num_Lock Ctrl <Btn1Down>:popup-menu(mainMenu) \n ~Meta <Btn1Down>:select-start() \n ~Meta <Btn1Motion>:select-extend() \n !Ctrl <Btn2Down>:popup-menu(vtMenu) \n !Lock Ctrl <Btn2Down>:popup-menu(vtMenu) \n !Lock Ctrl @Num_Lock <Btn2Down>:popup-menu(vtMenu) \n ! @Num_Lock Ctrl <Btn2Down>:popup-menu(vtMenu) \n ~Ctrl ~Meta <Btn2Down>:ignore() \n Meta <Btn2Down>:clear-saved-lines() \n ~Ctrl ~Meta <Btn2Up>:insert-selection(PRIMARY, CUT_BUFFER0) \n !Ctrl <Btn3Down>:popup-menu(fontMenu) \n !Lock Ctrl <Btn3Down>:popup-menu(fontMenu) \n !Lock Ctrl @Num_Lock <Btn3Down>:popup-menu(fontMenu) \n ! @Num_Lock Ctrl <Btn3Down>:popup-menu(fontMenu) \n ~Ctrl ~Meta <Btn3Down>:start-extend() \n ~Meta <Btn3Motion>:select-extend() \n Ctrl <Btn4Down>:scroll-back(1,halfpage,m) \n Lock Ctrl <Btn4Down>:scroll-back(1,halfpage,m) \n Lock @Num_Lock Ctrl <Btn4Down>:scroll-back(1,halfpage,m) \n @Num_Lock Ctrl <Btn4Down>:scroll-back(1,halfpage,m) \n <Btn4Down>:scroll-back(5,line,m) \n Ctrl <Btn5Down>:scroll-forw(1,halfpage,m) \n Lock Ctrl <Btn5Down>:scroll-forw(1,halfpage,m) \n Lock @Num_Lock Ctrl <Btn5Down>:scroll-forw(1,halfpage,m) \n @Num_Lock Ctrl <Btn5Down>:scroll-forw(1,halfpage,m) \n <Btn5Down>:scroll-forw(5,line,m) \n <BtnUp>:select-end(PRIMARY, CUT_BUFFER0) \n <BtnDown>:bell(0)
