NAME
mlterm - Multi Lingual TERMinal emulator on X
SYNOPSIS
mlterm [options]
DESCRIPTION
mlterm is a multi-lingual terminal emulator written from scratch, which supports various character sets
and encodings in the world and complex characters such as double width for East Asian, combining for
Thai, Vietnamese, and so on, and bi-direction for Arabic and Hebrew. Indic scripts are experimentally
supported. It also supports various unique feature such as anti-alias using FreeType, multiple XIM,
multiple windows, scrollbar API, scroll by mouse wheel, automatic selection of encoding, daemon mode, and
so on.
Supported encodings are: ISO-8859-[1-11], ISO-8859-[13-16], TIS-620 (same as ISO-8859-11), KOI8-R,
KOI8-U, KOI8-T, GEORGIAN-PS, TCVN5712, ISCII_(ASSAMESE|BENGALI|GUJARATI|
HINDI|KANNADA|MALAYALAM|ORIYA|PUNJABI|TAMIL|TELUGU), VISCII, CP125[0-8], CP874, EUC-JP, EUC-JISX0213,
Shift_JIS, Shift_JISX0213, ISO-2022-JP[1-3], EUC-KR, UHC, JOHAB, ISO-2022-KR, GB2312 (EUC-CN), GBK,
GB18030, ISO-2022-CN, HZ, EUC-TW, BIG5, BIG5HKSCS, and UTF-8. If you have already set locale (for
example LANG variable; see locale(7) for detail) mlterm will automatically select proper encoding.
OPTIONS
Note that bool is to be substituted by true or false.
-A, --aa(=bool)
Use anti-aliased fonts. This option works only with Xft or cairo for now. The default is true.
-B, --sbbg=color
Specify a background color of a scrollbar. A valid value for color is a color name or a RGB
value. The color name should be defined in rgb.txt or "color" configuration file. The RGB
value's format should be "#RRGGBB", "#RRGGBBAA", "rgb:RR/GG/BB" or "rgba:RR/GG/BB/AA".
-C, --ctl(=bool)
Enable complex text layouting on UTF8 encoding to support indic scripts and RTL (right-to-left)
languages such as Arabic and Hebrew. The default is true. (If mlterm -v outputs "no-indic" or
"no-bidi", indic scripts or RTL languages are not supported.)
-E, --km=encoding
Specify encoding. Valid encodings are listed in DESCRIPTION section above in this man page. AUTO
makes mlterm determine the according according to the current locale (default AUTO).
-F, --sbfg=color
Specify a foreground color of a scrollbar. See --sbbg option for valid values.
-G, --vertical=mode
Specify vertical writing mode. cjk for RTL vertical writing and mongol for LTR one. The default
is none which means horizontal writing mode.
-H, --bright=value
Brightness of background images in percent. See -p option for details of background images. The
default is 100 (keep original).
-I, --icon=name
Specify a name to be used when a mlterm window is iconified. The default is "mlterm".
-J, --dyncomb(=bool)
Enable dynamic character combining. "Dynamic" means that combining characters are stored in
without combining but they are displayed using combined form. This affects calculation of column
position, i.e., a pair of base character and combining character is counted to be two columns in
this mode, while it is counted to be one column in the normal mode. Under this option, a
(logical) column number and a character one-to-one correspondence. even for combining characters
(though not for fullwidth characters; see -Z/--multicol option for handling of fullwidth
characters). Thus, this mode enables you to use combining characters with software which does not
support combining characters. The default is false.
-K, --metakey=value
Specify a key to be interpreted as a META key. Valid values are: alt, meta, hyper, super, mod1,
mod2, mod3, mod4, and none. The default is none.

--role=role
Specify application role. (WM_WINDOW_ROLE property) The default is undefined.
-O, --sbmod=value
Specify the side to show a scrollbar. left for left side and right for right side. none turns
off a scrollbar. autohide shows a scrollbar only if mouse pointer is at the right edge of the
screen. The default is left.
-P, --clip(=bool)
Whether to enable CLIPBOARD (not only PRIMARY) selection. The default is true.
-Q, --vcur(=bool)
Change interpretation of cursor keys to be natural in vertical writing mode. This means that up

overrides DEC_SPECIAL in "font" configuration file, while DEC_SPECIAL in "aafont" (for Xft or
cairo) is always overridden.
-Z, --multicol(=bool)
Treat fullwidth characters (east Asian characters in most cases; which occupies two columns on the
screen) as they occupy two logical columns. It is the de-facto standard way to handle fullwidth
characters in east Asian terminal emulators (XFree86 xterm and kterm, cxterm, hanterm, rxvt,
eterm) and other systems such as MS-DOS, PC-9801, and so on. In most fonts, the glyphs of
fullwidth characters are designed assuming that their width are twice of normal characters and
won't display correctly without this option. The default is true.
-0, --crbg=color
Specify background color for cursor (default is same to foreground color). Valid values for color
are color names defined in rgb.txt and color rgb string whose format is "#RRGGBB", "#RRGGBBAA",
"rgb:RR/GG/BB" or "rgba:RR/GG/BB/AA".
-1, --wscr=value
Specify actual window width, by percentage against calculated value by multiplying font width by
column number. This is useful when you use a proportional font which includes some glyphs with
exceptionally large width, i.e., much larger "maximum width" than your expectation. In vertical
mode this option changes actual window height. The default is 100.
-3, --contrast=value)
Contrast of background image in percent. See -p option for details of background image. The
default is 100.
-4, --gamma=value)
Gamma of background image in percent. See -p option for details of background image. The default
is 100.
-5, --big5bug(=bool)
Enable a workaround for Big5 CTEXT bugs (which had been existed until XFree86 4.1.0). This
affects Big5 selections (i.e., copy-and-paste strings) in COMPOUND_TEXT format which mlterm sends.
The default is false.
-6, --stbs(=bool)
Don't exit backscroll mode when console applications output something. The default is false.
-7, --bel=mode
Behavior when BEL (0x07) is received. sound for beep , visual for blanking screen and sound|visual
for the both. The default is none which ignores BEL.
-8, --88591(=bool)
Use ISO8859-1 fonts for US-ASCII part of various encodings.
-9, --crfg=color
Specify foreground color for cursor (default is same to background color). Valid values for color
are color names defined in rgb.txt and color rgb string whose format is "#RRGGBB", "#RRGGBBAA",
"rgb:RR/GG/BB" or "rgba:RR/GG/BB/AA".
-$, --mc=value
Doubleclick/tripleclick interval in millisecond. The default is 250.
-%, --logseq(=bool)
Enable logging. Contents of stream received by mlterm will be logged under ~/.mlterm/. This
option is mainly intended to be used for debugging purposes. The default is false. Note that %
should be escaped to be supplied as a command line option on most shells.
-&, --borderless(=bool)
Asks the window manager to use no decorations at all. Warning: You will not be able to resize the
window. You probably want to use --geometry as well. The default is false.
-@, --screens=value
Specify number of screens (sessions) to be used in start up. The default is 1. Note that when
one of these screens are closed, sessions which were connected to the screens do not immediately
killed.
See MULTIPLE PTY section for details.
-*, --type=value
Specify the rendering engine to be used to draw fonts. xcore is conventional X11 core font
mechanism. xft means Xft mechanism and cairo means cairo mechanism. The default is cairo. On
platforms except X11, it is always xcore. (If mlterm -v outputs "no-xft" or "no-cairo", xft or
cairo is unavailable.)
-#, --initstr=value
Specify a string to be automatically sent after initialization of session. The value normally
will be parsed by a shell. See -e option to execute other application at start-up time.
-a, --ac=value
Specify number of columns to be occupied by a Unicode's "EastAsianAmbiguous" character. The
default is 1 except "ja" locale where the default is 2. Some of asian people may want to specify
2. See Unicode Standard Annex (UAX) #11 East Asian Width found at Unicode web site for details.
-b, --bg=color
Specify background color (default white). Valid values for color are color names defined in
rgb.txt and color rgb string whose format is "#RRGGBB", "#RRGGBBAA", "rgb:RR/GG/BB" or
"rgba:RR/GG/BB/AA".
-c, --cp932(=bool)
Use CP932 mapping table to convert from JIS X 0208 to Unicode when displaying JIS X 0208
characters using Unicode font in Xft or cairo mode. This is useful when you use proprietary
Japanese true type fonts which are intended to be used with Microsoft Windows, with mlterm with
encodings (such as EUC-JP, Shift_JIS, ISO-2022-JP, and so on) which contain JIS X 0208 as a coded
character set.
The reason is, such proprietary fonts may have glyphs only for Unicode code points into which JIS
X 0208 code points are converted using CP932 mapping table. (CP932 is a name of mapping table
which is used by Microsoft to convert from Shift_JIS [plus Microsoft private extended characters]
into Unicode. In Unicode's point of view, CP932 is a name of encoding which is similar to
Shift_JIS and is used by Japanese version of Microsoft Windows.) If you use such fonts for
encodings such as EUC-JP and Shift_JIS with JIS0208.TXT mapping table which mlterm adopts as the
standard, a few characters are mapped into Unicode code points where the fonts don't have glyphs.
Both of CP932.TXT and JIS0208.TXT mapping tables are supplied by Unicode Consortium, though they
are regarded to be obsolete.
The default is true.
-d, --display=string
Specify X display to connect with.
-e program [ arguments ... ]
Invoke the command in the mlterm window. This option must be the last option on the command line.
-f, --fg=color
Foreground color (default black). Valid values for color are color names defined in rgb.txt and
color rgb string whose format is "#RRGGBB", "#RRGGBBAA", "rgb:RR/GG/BB" or "rgba:RR/GG/BB/AA".
-g, --geometry=geometry
Specify size and position of the window; see X(7).
-h, --help(=bool)
Show help messages.
-i, --xim(=bool)
Whether to use XIM (X Input Method). Most east Asian people will want to enable this option.
Other people can also safely enable this. The default is true. The name of the XIM server to be
connected is specified by standard way (i.e., XMODIFIERS environmental variable).
-j, --daemon=value
Start as a daemon process. Note that mlclient is executed if a daemon process has already started.
Possible =values are "blend" and "genuine". See the chapter of DAEMON MODE for details. (If
mlterm -v outputs "no-daemon", this option is unavailable.)
-k, --meta=mode
Behavior of META key. esc for sending ESC and none for ignoring META key. The default is 8bit
which sets the most significant bit.
See -K option also.
-l, --sl=value
Specify number of lines of backlog or "unlimited". Over 65535(0xffff) is regarded as "unlimited".
The default is 128.
-m, --comb(=bool)
Enable combining characters by overstriking glyphs (recommended for TIS-620, TCVN5712, and UTF-8).
Note that fonts which contain combining characters which extend backward cannot be used, since
mlterm does combine characters by controlling the writing positions. This option is automatically
turned on when using --dyncomb option. The default is true.
-n, --noucsfont(=bool)
Use non-Unicode fonts even when mlterm encoding is UTF-8. Useful when you don't have ISO10646-1
fonts and you want to use UTF-8 encoding. The default is false.
-o, --lsp(=value)
Specify number of extra pixels between lines. The default is 0.
-p, --pic=path
Path for a wallpaper (background) image. Note that the wallpaper cannot be used with pseudo
transparent background. (If mlterm -v outputs "no-image", this option is unavailable.)
-r, --fade=ratio
Specify fading ratio for unfocused windows. 100 means no fading and 0 means darkest. The default
is 100
-s, --mdi(=bool)
Whether to use multiple document interface. The default is true. If you disable this option,
scrollbar and screen separation are unavailable.
-t, --transbg(=bool)
Whether to enable pseudo transparent background. Note that pseudo transparent background cannot
be used with wallpaper. The default is false.
-u, --onlyucsfont(=bool)
Use Unicode fonts even when mlterm encoding is not UTF-8. Useful when you have ISO10646 fonts but
you don't have other fonts and want to use non-UTF-8 encodings. Note that conversion to Unicode
is lossy. i.e. if mlterm encoding is not a subset of Unicode like ISO-2022-JP-2 or EUC-TW,
characters which are regarded as a same character in Unicode will be displayed with the same glyph
and cannot be distinguished.
The default is false.

PTY List
One process of mlterm may have multiple sessions and screens. The sessions may or may not have
corresponding screen, i.e., the number of sessions can be more than the number of screens. Such
situation can be achieved by closing a part of multiple screens from -@/--screens option. In such
case, the screen-less session can be designated to one of screens by choosing the session (pty)
from this list and push "select" button.
CONFIGURABLE MENU
Pushing control key and mouse button 1 invokes configurable menu displayer (mlterm-menu). It displays a
menu with items such as "Larger Font" or "UTF-8 encoding". Though a default menu definition is supplied,
you can freely define menu items by writing a menu configuration file. See Menu Configuration File
section for detail.
Note this feature needs GTK+ 2.x or later.
MULTIPLE XIM
mlterm can use multiple XIM (X Input Method) servers. The current XIM is specified by the GUI
configurator. Using this feature you can input multiple complex languages such as Japanese and Korean.
Locale to be used for communication with XIM can also be specified for each XIM. In the GUI
configurator, you can choose one of registered pair of XIM and its locale or you can input your favorite
XIM and its locale.
The locale for XIM is only used for communication with the XIM and is not related to the current mlterm
locale. You have to properly configure the XIM locale only when your XIM has preference on the locale of
XIM client (i.e., mlterm in this case). mlterm automatically convert the inputed string into proper
encoding and you don't have to care about it.
Of course the initial XIM is chosen by using standard configuration, i.e., using XMODIFIERS environmental
variable. See X(7) for detail on XIM and XMODIFIERS variable.
DAEMON MODE
When invoked with -j/--daemon command line option, mlterm starts to listen on a unix domain socket and
accept requests from mlclient.
With blend mlterm will exit when the final terminal window is closed. But with genuine, mlterm will
disconnect from X server windows and continues to work. In latter case, it's possible to stop and restart
a X server and revive the lasting sessions on mlterm.
SCROLLBAR
mlterm supports scrollbar API so that users can develop scrollbar libraries with arbitrary look and feel.
The scrollbar libraries can be used by putting the libraries at the specified directory (determined on
the compilation process) and invoke mlterm with -s -S name option. Scrollbar libraries named "sample",
"sample3", "athena", "motif", "mozmodern", and "next" are supplied.
ANTI-ALIAS
mlterm can use True Type fonts using -A option via FreeType library when it has been compiled with
anti-alias option.
Note this feature needs XFree86 4.0.2 or above and FreeType 2.0.2 or above.
WALLPAPER
mlterm can use background image (as known as wallpaper), by using -p/--pic option. You can also specify
the brightness of the image by using -H/--bright option.
Note this feature needs gdk-pixbuf.
MULTIPLE PTY
This is one of most unique features of mlterm. The number of windows can be specified using -P option.
Typing control + F1 opens another window which shares the same process. The maximum number of windows
can be specified using --maxptys option.
BACKSCROLL MODE
mlterm enters into backscroll mode by typing Shift + up or Shift + PageUp key. In the mode, you can use
the following keys.
j or Down
Scroll down one line.
k or Up
Scroll up one line.
u or PageUp
Scroll up one page.
d or PageDown
Scroll down one page.
keys defined in key configuration file
Shortcut keys work the same way as in normal mode. (INSERT_SELECTION, INSERT_CLIPBOARD, RESET and
COPY_MODE exit from the backscroll mode.)
other keys
Exit from the backscroll mode.
SELECTION
Selection is a mechanism to be used for copy-and-paste in X Window System. Thus, this section describes
on so-called copy-and-paste.
There are many encodings in the world. Though copy-and-paste needs sender and receiver and each of them
can use one of various encodings, mlterm is designed to be able to receive characters from various
encodings as much as possible.
There are two internationalized types of selection. One is COMPOUND_TEXT is the another is UTF8_STRING.
COMPOUND_TEXT is ISO2022-based and can distinguish character sets which a character belongs to. However,
the character sets which COMPOUND_TEXT supports are limited to ISO8859-* and East Asian character sets.
On the other hand, UTF8_STRING is Unicode-based and can express all characters from Unicode character
set. However, it cannot distinguish characters from different character sets which share one codepoint
in Unicode, which can be a problem especially for CJK Han Ideogram (in other words, Kanji, Hanji, or
Hanja). Note that UTF8_STRING is rather new and can be used only with XFree86.
Though the receiver of copy-and-paste can request the preferable type of selection, the sender may not
support the requested type. Thus mlterm has to be able to process both of COMPOUND_TEXT and UTF8_STRING.
On the other hand, encodings supported by mlterm (see DESCRIPTION section for detail) are classified into
four categories;
(a) Unicode itself
UTF-8.
(b) subset of Unicode and ISO-2022-compliant
"Subset of Unicode" means that Unicode supports round-trip compatibility for the encoding, i.e.,
the conversion of the encoding --> Unicode --> the encoding doesn't lose any information.
"ISO-2022-compliant" means that the encoding can be regarded as a subset of ISO-2022 where a part
of ISO-2022 control codes and escape sequences are not supported. Many popular encodings belong
to this category such as ISO-8859-*, EUC-*, ISO-2022-KR, TIS-620, TCVN5712, and so on.
(c) subset of Unicode and non-ISO-2022-compliant
Some of popular encodings such as Shift_JIS, Big5, GBK, GB18030, Johab, and so on belongs to this
category.
(d) not subset of Unicode
ISO-2022-JP, ISO-2022-JP-2, ISO-2022-JP-3, EUC-TW, and so on. All of them are ISO-2022-compliant.
Now the behavior of mlterm can be explained.
-------------------------------------------------------
encoding received selection how to process?
-------------------------------------------------------
a COMPOUND_TEXT convert to Unicode
a UTF8_STRING no need for conversion
b COMPOUND_TEXT user preference *1
b UTF8_STRING convert to the encoding *2
c COMPOUND_TEXT user preference *1
c UTF8_STRING convert to the encoding *2
d COMPOUND_TEXT no need for conversion *3
d UTF8_STRING convert to the encoding *2
-------------------------------------------------------
*1 Characters from unsupported character sets (i.e., characters which cannot be expressed in the mlterm
encoding) may appear in the selection (received copy-and-paste string). If you want to receive
characters which are equivalent to characters which are supported in the current mlterm encoding (i.e.,
characters which share the same codepoint in Unicode), you can use -U (or --viaucs) option. Otherwise,
these characters are pasted into mlterm using ISO-2022 escape sequence (when mlterm encoding is category
b). Note such ISO-2022 escape sequences are illegal in the current mlterm encoding and the application
software will need special feature to treat them properly, though it is displayed well in mlterm. When
mlterm encoding is category c, such characters are simply ignored (when -U option is not enabled).
*2 Characters which cannot be converted into mlterm encoding are simply ignored.
*3 Characters from unsupported character sets will be pasted into mlterm using ISO-2022 escape sequence.
COPY MODE
mlterm enters into copy mode by typing Shift + Control + Return key. In the mode, you can move in the
screen including backlog, select region and copy it by the following keys.
j or Down

Any other keys
Stop selection.
CONFIGURATION
mlterm loads configuration files of "main", "font", "vfont", "tfont", "aafont", "vaafont", "taafont",
"color", "key", "termcap", and "xim" on start up. "menu" configuration file is loaded by the
configurable menu displayer (mlterm-menu). See the section of CONFIGURABLE MENU for detail.
Configuration files for one user are to be located in "~/.mlterm/" directory, while location for
configuration files for all users depends on the compilation option. Possible locations are "/etc/",
"/etc/X11/", "/usr/X11R6/lib/X11/mlterm/", and so on.

ISO10646_UCS4_1=font
ISO10646_UCS4_1_FULLWIDTH=font
U+XXXX-XXXX=font
Specify fonts for corresponding character sets. The format is different between "font", "vfont"
"tfont" files and "aafont", "vaafont" "taafont" files.
In "font", "vfont", "tfont" files, "font" is specified in "NAME:PERCENT" format where "SIZE" is
font size in pixel, and "NAME" is XLFD or alias names of X fonts. If "NAME" contains "%d", it is
replaced by an appropriate font size number. ":PERCENT" is multiplied by font size and decides
character width of a font. If ":PERCENT" is omitted, max font width is used for it.
In "aafont", "vaafont", "taafont" files, "font" is specified in "FAMILY WEIGHT SLANT SIZE:PERCENT"
format. ":PERCENT" is multiplied by font size and decides character width of a font. If
":PERCENT" is omitted, 'M' width is used for it.
mlfc command generates ~/.mlterm/aafont automatically.
charset_BOLD=font
Specify boldface fonts.
charset_ITALIC=font
Specify italic fonts.
charset_BOLD_ITALIC=font
Specify bold-italic fonts.
U+XXXX-XXXX=font
Specify which fonts to use for unicode ranges except U+00-7f.
Color Configuration File
The color configuration file "color" has the following key.
COLORNAME=RGB
Assign a concrete color for the name COLORNAME. Default colors used by mlterm are black, red,
green, yellow, blue, magenta, cyan, and white. and can be overridden here.
For highlighted colors, a name with "hl_" prefix will be automatically searched. i.e. for bold
red characters, "hl_red" is searched instead of "red".
17 - 230 and 232 - 255 in 256 colors can be also overridden.
The format of RGB is either "RRRR-GGGG-BBBB" (where RRRR, GGGG, and BBBB are hexadecimal value
from 0 to ffff), "#RRGGBB", "#RRGGBBAA", "rgb:RR/GG/BB" or "rgba:RR/GG/BB/AA"(where RR, GG, and BB
are hexadecimal value from 00 to ff).
If mlterm failed to parse a entry, the color will be regarded as black.
XIM Configuration File
The X Input Methods configuration file "xim" has the following format
XIM=locale
where XIM is XIM name and locale is locale name used for communication with the XIM server. For example,
kinput2=ja_JP.eucJP
Ami=ko_KR.eucKR
xcin-zh_CN.GB2312=zh_CN.GB2312
These settings are used to create list of XIMs by the GUI configurator. Though a XIM which is not listed
in this file can't be selected from the list, it can be selected by specifying its name directly.
Feature Key Configuration File
The feature key configuration file "key" has the following format.
KEY=FEATURE
Here, the format for KEY is "(MASK+)KEY", where MASK is one of Control, Shift, Mod1, Mod2, Mod3, Mod4,
Mod5, Mod and Alt. You can specify multiple "MASK+"s. You can search spellings of KEY by using xev(1)
command or searching keysym macros from /usr/X11R6/include/X11/keysymdefs.h (or the equivalent file in
your X11 include directory) and omit the prefix XK_. Double quotation marks are not needed. You can
specify Button1, Button2, Button3, Button4 or Button5 as KEY.
FEATURE is one of IM_HOTKEY, EXT_KBD, OPEN_SCREEN, NEW_PTY, OPEN_PTY, NEXT_PTY, PREV_PTY, VSPLIT_SCREEN,
HSPLIT_SCREEN, CLOSE_SCREEN, NEXT_SCREEN, PREV_SCREEN, HEXPAND_SCREEN, VEXPAND_SCREEN, PAGE_UP,
SCROLL_UP, SCROLL_UP_TO_MARK, SCROLL_DOWN_TO_MARK, SET_MARK, INSERT_SELECTION, INSERT_CLIPBOARD, RESET,
COPY_MODE, "STRING", or "proto:STRING".
IM_HOTKEY
Switch conversion mode of m17n library and kdb input methods. (default UNUSED)
EXT_KBD
Activate or deactivate kbd input method. (This feature was obsoleted by IM_HOTKEY)
OPEN_SCREEN
Open new pty in new screen (default Ctrl+F1).
NEW_PTY
Same as OPEN_SCREEN (obsoleted).
OPEN_PTY
Open new pty in current screen (default Ctrl+F2).
NEXT_PTY
Switch to a next free pty (default Ctrl+F3).
PREV_PTY
Switch to a previous free pty (default Ctrl+F4).
HSPLIT_SCREEN
Open new pty in horizontally split screen (default Shift+F1). (If mlterm -v outputs "no-split",
this shortcut key is unavailable.)
VSPLIT_SCREEN
Open new pty in vertically split screen (default Shift+F2). (If mlterm -v outputs "no-split",
this shortcut key is unavailable.)
NEXT_SCREEN
Switch to a next unfocused screen (default Shift+F3).
PREV_SCREEN
Switch to a previous unfocused screen (default Shift+F4).
CLOSE_SCREEN
Close current screen (default Shift+F5).
HEXPAND_SCREEN
Expand current screen horizontally (default Shift+F6). (If mlterm -v outputs "no-split", this
shortcut key is unavailable.)
VEXPAND_SCREEN
Expand current screen vertically (default Shift+F7). (If mlterm -v outputs "no-split", this
shortcut key is unavailable.)
PAGE_UP
Start backscroll mode and scroll up one page (default Shift+Prior).
SCROLL_UP
Start backscroll mode and scroll up by one line (default Shift+Up).
SCROLL_UP_TO_MARK
Start backscroll mode and scroll up to the next marked line (default Control+Shift+Up).
SCROLL_DOWN_TO_MARK
Scroll down to the next marked line (default Control+Shift+Down).
SET_MARK
Set mark to the current line (default Control+Shift+m).
INSERT_SELECTION
Insert selection (default Shift+Insert).
INSERT_CLIPBOARD
Insert clipboard (default UNUSED). (Available on x11 alone)
RESET Reset terminal (default Pause).
COPY_MODE
Enter copy mode which enables you to select and copy region by keyboard (default
Control+Shift+Return).
"STRING"
The specified string is issued when the KEY key is pressed. Double quotation marks are required
around the STRING. Note that you cannot control the status of mlterm by sending terminal control
codes such as "\x1b]5379;encoding=utf8\x0a" because the code sequence will be caught by your shell
(or something running on it). To deliver control sequences to mlterm directly, use "proto:STRING"
instead.
"proto:STRING"
The specified string is assumed to mlterm's original control sequence. A list of sequences should
be found in doc/en/PROTOCOL. For example, "proto:encoding=utf8" means changing the current
character encoding to UTF-8. If you want to show issued STRING in the screen in pressing shortcut
keys, prepend "(echo)" to STRING. For example, "proto:(echo)encoding=utf8" shows "Config:
encoding=utf8".
"exesel:STRING"
The specified string is assumed to a command to be executed with selected strings as arguments.
"%s" in a command string is replaced by selected strings. For example, "exesel:mlclient -e w3m"
means executing "mlclient -e w3m [selected text]".
"menu:STRING"
The specified string is assumed to a configuration program to be executed. For example,
"menu:mlterm-menu" means executing mlterm-menu.
Terminal Behavior Configuration File
This configuration file determines the behaviors of mlterm that should match the definition of terminfo
and termcap. In principle, this file should not be edited and, instead, you should choose a proper value
for TERM variable (i.e., proper terminfo/termcap definition) which meets mlterm's behavior. (Since
mlterm' can behave as a xterm/kterm to some extent, TERM=kterm / TERM=xterm should give acceptable
results.) However, sometimes you may not want to edit your terminfo and termcap. Your software may
don't understand terminfo nor termcap, or your terminfo/termcap entry is shared by several terminal
emulators and changing it will break other terminals. In such cases, you can configure mlterm so that it
works well on existing terminfo/termcap definitions on your systems. This is also useful for
distributors of operating systems (like Debian) with strict policy of terminal emulators' behaviors.
You can define the behaviors of mlterm for each value of TERM variable, so that you don't need to edit
termcap file each time you login into other systems and use different value of TERM variable by -y
option. You can also specify the default behavior when TERM variable is different from all of specified
TERM names in the termcap file.
The grammar of this configuration file is resemble to the grammar of termcap entries. First, one or more
name(s) of TERM is written. Multiple names are connected with vertical line character '|'. Special name
'*' is for default. Then colon ':' comes, and keys are written separated by colons. Configuration(s)
for other TERM will follow after new line.
Followings are available keys for each TERM value.
kD=sequence
Specify sequence to be outputted when Delete key is pushed (default \E[3~).
kb=sequence
Specify sequence to be outputted when BackSpace key is pushed (default ^H).
kh=sequence
Specify sequence to be outputted when HOME key is pushed in application cursor key mode. (default
\EOH).
@7=sequence
Specify sequence to be outputted when END key is pushed in application cursor key mode. (default
\EOF).
k1=sequence
Specify sequence to be outputted when F1 key is pushed (default \EOP).
k2=sequence
Specify sequence to be outputted when F2 key is pushed (default \EOQ).
k3=sequence
Specify sequence to be outputted when F3 key is pushed (default \EOR).
k4=sequence
Specify sequence to be outputted when F4 key is pushed (default \EOS).
k5=sequence
Specify sequence to be outputted when F5 key is pushed (default \E[15~).
ut Specify the way how the screen is erased by control codes. If ut is written in the termcap file,
charcells are painted by the current background color when erased; otherwise the charcells are
painted by the initial background color. Default is non-ut behavior.
The following special characters can be used to specify sequence in keys of kD/kb/kh/@7.
\E ESC code (0x1b).
^? DEL code (0x7f).
^A, ^B,...
Corresponding control code (0x01 - 0x1a).
Menu Configuration File
This configuration file defines the menu displayed by the configurable menu displayer mlterm-menu. See
