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|ROMAN|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-let) languages such as Arabic and Hebrew. The default is true.

-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

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.

The default is none which turns off scrollbar.

-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 and down arrow keys are treated as backward (left arrow in horizontal
LTR) and forward (right arrow in horizontal LTR), respectively. In cjk
-G/--vertical mode, left and right arrow keys are also treated as next line (down
arrow in horizontal LTR) and previous line (up arrow in horizontal LTR),
respectively, while vice versa in mongol mode. The default is false.

-R, --fsrange=range
Set acceptable range of font size. The format is "minsize-maxsize", where minsize
and maxsize are font sizes in pixel (default 6-30). The GUI configurator and other
means for setting fontsize should honor the range.

-S, --sbview=name
Select a type of scrollbar. See SCROLLBAR section below for details. The default
is "simple" which means the built-in simple scrollbar.

-T, --title=name
Specify a title for a mlterm window. The default is "mlterm".

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

-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. The default is 100.

-2, --hscr=value
Specify actual screen height, like -1/--wscr does for width. The default is 100.

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 xft.

-#, --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.

-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". 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.

-q, --extkey(=bool)
Enable extended keys for backscroll mode. The default is false. Extended scroll
keys are SCROLL_UP, up arrow, and "k" (for scrolling one line backward) and
SCROLL_DOWN, down arrow, and "j" (for scrolling one line forward). Please note
that concrete keys for symbols of SCROLL_UP and SCROLL_DOWN are specified in key
configuration file. Only keys of PAGE_UP and PAGE_DOWN (which are specified in key
configuration file) are available by default.

-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.

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", "sample2", "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.

d or PageDown
Scroll down one page.

u or PageUp
Scroll up one page.

Shift + space
Initialize XIM.

Shift + Insert
Insert selection.

Control + F1
Open a new pty window.

keys defined in key configuration file
PAGE_UP, PAGE_DOWN, SCROLL_UP, and SCROLL_DOWN keys are defined in the file.

other keys
Exit from the backscroll mode.

Please note that keys other than PAGE_UP and PAGE_DOWN in key configuration file are
available only when you used -q/--extkey command option.

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.

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.

The names and the roles of configuration files are:

main Main configuration items which can be overridden by command line options.

font Configurations for ordinary X fonts.

vfont Configurations for ordinary X fonts of variable column width.

tfont Configurations for ordinary X fonts of vertical writing.

aafont Configurations for Xft or cairo fonts.

vaafont
Configurations for Xft or cairo fonts of variable column width.

taafont
Configurations for Xft or cairo fonts of vertical writing.

key Key definitions for special features of mlterm.

termcap
Define mlterm's behaviors which affects terminfo and termcap definition.

xim Define preset locales for X Input Methods which are shown in the GUI configurator.
Of course you can input XIM names and locales for the GUI configurator which are
not listed in this configuration file.

menu Define menu items which is displayed by configurable menu displayer.

The contents of these configuration files (other than menu) consist of lines of
"key=value" format. Lines beginning with "#" are ignored.

Note that the configuration files are changed since version 1.9.44.

HKSCS=fonts
CNS11643_1992_n=fonts
ISO10646_UCS4_1=fonts
ISO10646_UCS4_1_FULLWIDTH=fonts
U+XXXX-XXXX=fonts
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;SIZE,NAME:PERCENT;SIZE,NAME:PERCENT;..." format where "SIZE" is font
size in pixel, and "NAME" is XLFD or alias names of X fonts. If the first "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-ENCODING:PERCENT;SIZE,FAMILY WEIGHT SLANT SIZE-
ENCODING:PERCENT;SIZE,FAMILY WEIGHT SLANT SIZE-ENCODING:PERCENT;..." format. The
first pair of FAMILY WEIGHT SLANT SIZE and ENCODING specifies the default font and
the others with SIZE are for specific sizes. ":PERCENT" is multiplied by font size
and decides character width of a font. If ":PERCENT" is omitted, 'W' width is used
for it.

charset_BOLD=fonts
Specify boldface fonts.

charset_ITALIC=fonts
Specify italic fonts.

charset_BOLD_ITALIC=fonts
Specify bold-italic fonts.

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 hilighted colors, a name with "hl_" prefix will be automatically searched.
i.e. for bold read character, "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, PAGE_DOWN, SCROLL_UP, SCROLL_DOWN, INSERT_SELECTION, "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 splitted screen (default Shift+F1).

VSPLIT_SCREEN
Open new pty in vertically splitted screen (default Shift+F2).

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).

VEXPAND_SCREEN
Expand current screen vertically (default Shift+F7).

PAGE_UP
Start backscroll mode and scroll up one page (default Shift+Prior).

PAGE_DOWN
Scroll down one page. (default Shift+Next).

SCROLL_UP
Start backscroll mode and scroll up by one line (default Shift+Up). Note this key
is enabled only when -q/--extkey option is used.

SCROLL_DOWN
Scroll down one line (default Shift+Down). Note this key is enabled only when
-q/--extkey option is used.

INSERT_SELECTION
Insert selection (default Shift+Insert).

"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.

"exesel:STRING"
The specified string is assumed to a command to be executed with selected strings
as arguments. 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.
