MXTERM(1) X Version 11 MXTERM(1)
Release 5
NAME
mxterm - terminal emulator for X with Motif support
SYNOPSIS
mxterm [-toolkitoption ...] [-option ...]
DESCRIPTION
The mxterm program is a terminal emulator for the X Window System. It
provides DEC VT102 and Tektronix 4014 compatible terminals for
programs that can't 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), mxterm will use
the facilities to notify programs running in the window whenever it is
resized.
The VT102 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 VT102 window, and the ``Tek Options'' menu in
the 4014 window.
EMULATIONS
The VT102 emulation is fairly complete, but does not support the
blinking character attribute nor the double-wide and double-size
character sets. Termcap(5) entries that work with mxterm include
``xterm,'' ``vt102,'' ``vt100'' and ``ansi,'' and mxterm automatically
searches the termcap file in this order for these entries and then
sets the ``TERM'' and the ``TERMCAP'' environment variables.
Many of the special mxterm features (like logging) may be modified
under program control through a set of escape sequences different from
the standard VT102 escape sequences. (See the MXterm Control Sequences
document.)
The Tektronix 4014 emulation is also fairly good. Four different font
sizes and five different lines types are supported. The Tektronix
text and graphics commands are recorded internally by mxterm 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
``COPYyy-MM-dd.hh:mm:ss'', where yy, 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 mxterm is started in, or the
home directory for a login mxterm).

OTHER FEATURES
MXterm 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 mxterm allows the visual editor vi(1) to
switch to the alternate screen for editing and to restore the screen
on exit.
In either VT102 or Tektronix mode, there are escape sequences to
change the name of the windows and to specify a new log file name.
See MXterm Control Sequences for details. Enabling the escape
sequence to change the log file name is a compile-time option; by
default this escape sequence is ignored for security reasons.
OPTIONS
The mxterm terminal emulator accepts all of the standard X Toolkit
command line options as well as the following (if the option begins
with a `+' instead of a `-', the option is restored to its default
value):
-help This causes mxterm to print out a verbose message describing
its options.
-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 mxterm
window will resize appropriately.
-ah This option indicates that mxterm should always highlight the
text cursor. By default, mxterm will display a hollow text
cursor whenever the focus is lost or the pointer leaves the
window.
+ah This option indicates that mxterm should do text cursor
highlighting based on focus.
-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. The default is 2.
-cb Set the vt100 resource cutToBeginningOfLine to FALSE.
- 2 - Formatted: November 14, 2024
MXTERM(1) X Version 11 MXTERM(1)
Release 5
+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.
-cn This option indicates that newlines should not be cut in
line-mode selections.
+cn This option indicates that newlines should be cut in line-mode
selections.
-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 mxterm should work around a bug in
the curses(3x) cursor motion package that causes the more(1)
program to display lines that are exactly the width of the
window and are followed by a line beginning with a tab to be
displayed incorrectly (the leading tabs are not displayed).
+cu This option indicates that that mxterm should not work around
the curses(3x) bug mentioned above.
-e program [arguments ...]
This option specifies the program (and its command line
arguments) to be run in the mxterm 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.
-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
normal font. 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. The default
is to do overstriking of the normal font.
-im Turn on the useInsertMode resource.
+im Turn off the useInsertMode resource.
-j This option indicates that mxterm should do jump scrolling.
Normally, text is scrolled one line at a time; this option
allows mxterm to move multiple lines at a time so that it
doesn't fall as far behind. Its use is strongly recommended
since it make mxterm much faster when scanning through large
- 3 - Formatted: November 14, 2024
MXTERM(1) X Version 11 MXTERM(1)
Release 5
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 mxterm should not do jump
scrolling.
-l This option indicates that mxterm should send all terminal
output to a log file as well as to the screen. This option
can be enabled or disabled using the ``VT Options'' menu.
+l This option indicates that mxterm should not do logging.
-lf filename
This option specifies the name of the file to which the output
log described above is written. If file begins with a pipe
symbol (|), the rest of the string is assumed to be a command
to be used as the endpoint of a pipe. The ability to log to a
pipe is a compile-time option which is disabled by default for
security reasons. The default filename is ``MXtermLog.XXXXX''
(where XXXXX is the process id of mxterm) and is created in
the directory from which mxterm was started (or the user's
home directory in the case of a login window).
-ls This option indicates that the shell that is started in the
mxterm window 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).
+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 mxterm 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.
-ms color
This option specifies the color to be used for the pointer
cursor. 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.

-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.
-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 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.
-s This option indicates that mxterm may scroll asynchronously,
meaning that the screen does not have to be kept completely up
to date while scrolling. This allows mxterm 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 mxterm should scroll synchronously.
-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
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
- 5 - Formatted: November 14, 2024
MXTERM(1) X Version 11 MXTERM(1)
Release 5
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. The default is 64.
-t This option indicates that mxterm should start in Tektronix
mode, rather than in VT102 mode. Switching between the two
windows is done using the ``Options'' menus.
+t This option indicates that mxterm should start in VT102 mode.
-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. 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.
-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.
-ut This option indicates that mxterm shouldn't write a record
into the the system log file /etc/utmp.
+ut This option indicates that mxterm should write a record into
the system log file /etc/utmp.
-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.
-wf This option indicates that mxterm 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 mxterm show not wait before
starting the subprocess.
- 6 - Formatted: November 14, 2024
MXTERM(1) X Version 11 MXTERM(1)
Release 5
-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 specifies the last two letters of the name of a
pseudoterminal to use in slave mode, plus the number of the
inherited file descriptor. The option is parsed ``%c%c%d''.
This allows mxterm to be used as an input and output channel
for an existing program and is sometimes used in specialized
applications.
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 mxterm's windows. It is
equivalent to -title.
-n string
This option specifies the icon name for mxterm'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 mxterm:

resources are to be obtained, rather than the default
executable file name. Name should not contain ``.'' or ``*''
characters.
-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.
-rv This option indicates that reverse video should be simulated
by swapping the foreground and background colors.
-geometry geometry
This option specifies the preferred size and position of the
VT102 window; see X(1).
-display display
This option specifies the X server to contact; see X(1).
-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.
-iconic This option indicates that mxterm should ask the window
manager to start it as an icon rather than as the normal
window.

RESOURCES
The program understands all of the core X Toolkit resource names and
classes as well as:
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.
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.
ttyModes (class TtyModes)

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, and lnext.
Control characters may be specified as ^char (e.g. ^c or ^u)
and ^? may be used to indicate Delete. This is very useful
for overriding the default terminal settings without having to
do an stty every time an mxterm is started.
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.''
utmpInhibit (class UtmpInhibit)
Specifies whether or not mxterm should try to record the
user's terminal in /etc/utmp.
sunFunctionKeys (class SunFunctionKeys)
Specifies whether or not Sun Function Key escape codes should
be generated for function keys instead of standard escape
sequences.

(class VT100):
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 creates a
very large security hole.
alwaysHighlight (class AlwaysHighlight)
Specifies whether or not mxterm should always display a
highlighted text cursor. By default, a hollow text cursor is
displayed whenever the pointer moves out of the window or the
window loses the input focus.
appcursorDefault (class AppcursorDefault)
If ``true,'' the cursor keys are initially in application
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.
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.
boldFont (class BoldFont)
Specifies the name of the bold font to use instead of
overstriking.
c132 (class C132)
Specifies whether or not the VT102 DECCOLM escape sequence

the process id of mxterm).
logging (class Logging)
Specifies whether or not a terminal session should be logged.
The default is ``false.''
logInhibit (class LogInhibit)
Specifies whether or not terminal session logging should be
inhibited. The default is ``false.''

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.

POINTER USAGE
Once the VT102 window is created, mxterm 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
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. Double-clicking selects by words. Triple-
clicking selects by lines. Quadruple-clicking goes back to
- 19 - Formatted: November 14, 2024
MXTERM(1) X Version 11 MXTERM(1)
Release 5
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. If the key/button bindings specify that an X
selection is to be made, mxterm 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, mxterm 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 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 dows 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

Release 5
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
MXterm 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
horizontal line. The top portion contains various 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. The bottom
portion of the menu are command entries; selecting one of these
performs the indicated function.
The mxterm menu pops up when the ``control'' key and pointer button
one are pressed in a window. The mainMenu contains items that apply
to both the VT102 and Tektronix windows. The Secure Keyboard mode is
be used when typing in passwords or other sensitive data in an
unsecure environment; see SECURITY below. Notable entries in the
command section of the menu are the Continue, Suspend, Interrupt,
Hangup, Terminate and Kill which sends the SIGCONT, SIGTSTP, SIGINT,
SIGHUP, SIGTERM and SIGKILL signals, respectively, to the process
group of the process running under mxterm (usually the shell). The
Continue function is 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
program 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 mxterm 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 MXterm Control Sequences) and the
current 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. MIT servers,
run under xdm, are capable of using a ``magic cookie'' authorization
- 21 - Formatted: November 14, 2024
MXTERM(1) X Version 11 MXTERM(1)
Release 5
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 keyboard. This 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
that host-based control, but a simple mechanism exists for protecting
keyboard input in mxterm.
The mxterm menu (see MENUS above) contains a Secure Keyboard entry
which, when enabled, ensures that all keyboard input is directed only
to mxterm (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. 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 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 mxterm
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 middle mouse button twice in rapid succession will cause
all characters of the same class (e.g. letters, white space,
punctuation) to be selected. 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 simply a list of range:value pairs where the range is
either a single number or low-high in the range of 0 to 127,
- 22 - Formatted: November 14, 2024
MXTERM(1) X Version 11 MXTERM(1)
Release 5
corresponding to the ASCII 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.
The default table is
static int charClass[128] = {

48, 48, 48, 123, 124, 125, 126, 1};
For example, the string ``33:48,37:48,45-47:48,64:48'' 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 very 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

Release 5
behavior. The following actions are provided for using within the
vt100 or tek4014 translations resources:
bell([percent])
This action rings the keyboard bell at the specified
percentage above or below the base volume.
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-seven-bit()
This action is a synonym for insert()
insert-eight-bit()
This action inserts an eight-bit (Meta) version of the
character or string associated with the key that was pressed.
The exact action depends on the value of the eightBitInput
resource.
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.
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.
popup-menu(menuname)
This action displays the specified popup menu. Valid names
(case is significant) include: mainMenu, vtMenu, fontMenu,
and tekMenu.
secure()
This action toggles the Secure Keyboard mode described in the
section named SECURITY, and is invoked from the securekbd
entry in mainMenu.
select-start()

making selections.
select-extend()
This action tracks the pointer and extends the selection. It
should only be bound to Motion events.
select-end(destname [, ...])
This action puts the currently selected text into all of the
selections or cutbuffers specified by destname.
select-cursor-start()
This action is similar to select-start except that it begins
the selection at the current text cursor position.
select-cursor-end(destname [, ...])
This action is similar to select-end except that it should be
used with select-cursor-start.
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 mxterm 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.
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.
scroll-back(count [,units])
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.

ENVIRONMENT
MXterm sets the environment variables ``TERM'' and ``TERMCAP''
properly for the size window you have created. It also uses and sets
the environment variable ``DISPLAY'' to specify which bit map display
terminal to use. The environment variable ``WINDOWID'' is set to the
X window id number of the mxterm window.

BUGS
Large pastes do not work on some systems. This is not a bug in
mxterm; it is a bug in the pseudo terminal driver of those systems.
mxterm 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.
