1009The format of I<sym> is "I<(modifiers-)key>", where I<modifiers> can be 1051Using this resource, you can map key combinations such as
1010any combination of B<ISOLevel3>, B<AppKeypad>, B<Control>, B<NumLock>, 1052C<Ctrl-Shift-BackSpace> to various actions, such as outputting a different

1013B<2>, B<3>, B<4>, B<5>. 1055extension might provide.
1056
1057The key combination that triggers the action, I<sym>, has the following format:
1058
1059 (modifiers-)key
1060
1061Where I<modifiers> can be any combination of B<ISOLevel3>, B<AppKeypad>,
1062B<Control>, B<NumLock>, B<Shift>, B<Meta>, B<Lock>, B<Mod1>, B<Mod2>,
1063B<Mod3>, B<Mod4>, B<Mod5>, and the abbreviated B<I>, B<K>, B<C>, B<N>,
1064B<S>, B<M>, B<A>, B<L>, B<1>, B<2>, B<3>, B<4>, B<5>.
1014 1065

1016whatever modifier the NumLock key, Meta/Alt keys or ISO Level3 Shift/AltGr 1067whatever modifier the NumLock key, Meta/Alt keys or ISO Level3 Shift/AltGr
1017keys are being mapped. B<AppKeypad> is a synthetic modifier mapped to the 1068keys are being mapped. B<AppKeypad> is a synthetic modifier mapped to the
1018current application keymap mode state. 1069current application keymap mode state.
1019 1070
1020The spellings of I<key> can be obtained by using B<xev>(1) command or 1071Due the the large number of modifier combinations, a key mapping will
1021searching keysym macros from B</usr/X11R6/include/X11/keysymdef.h> and 1072match if I<at least> the specified identifiers are being set, and no other
1073key mappings with those and more bits are being defined. That means that
1074defining a mapping for C<a> will automatically provide definitions for
1075C<Meta-a>, C<Shift-a> and so on, unless some of those are defined mappings
1076themselves. See the C<builtin:> action, below, for a way to work around
1077this when this is a problem.
1078
1079The spelling of I<key> depends on your implementation of X. An easy way to
1080find a key name is to use the B<xev>(1) command. You can find a list by
1081looking for the C<XK_> macros in the B<X11/keysymdef.h> include file (omit
1022omitting the prefix B<XK_>. Alternatively you can specify I<key> by its hex 1082the C<XK_> prefix). Alternatively you can specify I<key> by its hex keysym
1023keysym value (B<0x0000 - 0xFFFF>). Note that the lookup of I<sym>s is not 1083value (B<0x0000 - 0xFFFF>).
1024performed in an exact manner; however, the closest match is assured.
1025 1084
1026I<string> may contain escape values (C<\a>: bell, C<\b>: backspace, 1085As with any resource value, the I<action> string may contain backslash
1027C<\e>, C<\E>: escape, C<\n>: newline, C<\r>: carriage return, C<\t>: tab, 1086escape sequences (C<\n>: newline, C<\\>: backslash, C<\000>: octal
1028C<\000>: octal number) or verbatim control characters (C<^?>: delete, 1087number), see RESOURCES in C<man 7 X> for further details.
1029C<^@>: null, C<^A> ...) and may be enclosed with double quotes so that it
1030can start or end with whitespace.
1031 1088
1032Please note that you need to double the C<\> in resource files, as 1089An action starts with an action prefix that selects a certain type
1033Xlib itself does it's own de-escaping (you can use C<\033> instead of 1090of action, followed by a colon. An action strings without colons is
1034C<\e> (and so on), which will work with both Xt and @@RXVT_NAME@@'s own 1091interpreted as a literal string to pass to the tty (as if they were
1035processing). 1092prefixed with C<string:>).
1036 1093
1037You can define a range of keysyms in one shot by providing a I<string> 1094The following action prefixes are known - extensions can provide
1038with pattern B<list/PREFIX/MIDDLE/SUFFIX>, where the delimeter `/' 1095additional prefixes:
1039should be a character not used by the strings.
1040 1096
1041Its usage can be demonstrated by an example: 1097=over 4
1042 1098
1043 URxvt.keysym.M-C-0x61: list|\033<M-C-|abc|> 1099=item string:STRING
1044 1100
1045The above line is equivalent to the following three lines: 1101If the I<action> starts with C<string:> (or otherwise contains no colons),
1102then the remaining C<STRING> will be passed to the program running in the
1103terminal. For example, you could replace whatever Shift-Tab outputs by the
1104string C<echo rm -rf /> followed by a newline:
1046 1105
1047 URxvt.keysym.Meta-Control-0x61: \033<M-C-a> 1106 URxvt.keysym.Shift-Tab: string:echo rm -rf /\n
1048 URxvt.keysym.Meta-Control-0x62: \033<M-C-b>
1049 URxvt.keysym.Meta-Control-0x63: \033<M-C-c>
1050 1107
1108This could in theory be used to completely redefine your keymap.
1109
1110=item command:STRING
1111
1051If I<string> takes the form of C<command:STRING>, the specified B<STRING> 1112If I<action> takes the form of C<command:STRING>, the specified B<STRING>
1052is interpreted and executed as @@RXVT_NAME@@'s control sequence. For 1113is interpreted and executed as @@RXVT_NAME@@'s control sequence (basically
1114the opposite of C<string:> - instead of sending it to the program running
1115in the terminal, it will be treated as if it were program output). This is
1116most useful to feed command sequences into @@RXVT_NAME@@.
1117
1053example the following means "change the current locale to C<zh_CN.GBK> 1118For example the following means "change the current locale to C<zh_CN.GBK>

1060manpage. For example, the F<selection> extension (activated via 1125font-switching at runtime:
1061C<@@RXVT_NAME@@ -pe selection>) listens for C<selection:rot13> events:
1062 1126
1063 URxvt.keysym.M-C-c: perl:selection:rot13 1127 URxvt.keysym.M-C-1: command:\033]50;suxuseuro\007
1128 URxvt.keysym.M-C-2: command:\033]50;9x15bold\007
1064 1129
1065Due the the large number of modifier combinations, a defined key mapping 1130Other things are possible, e.g. resizing (see @@RXVT_NAME@@(7) for more
1066will match if at I<at least> the specified identifiers are being set, and 1131info):
1067no other key mappings with those and more bits are being defined. That
1068means that defining a key map for C<a> will automatically provide
1069definitions for C<Meta-a>, C<Shift-a> and so on, unless some of those are defined
1070mappings themselves.
1071 1132
1072Unfortunately, this will override built-in key mappings. For example 1133 URxvt.keysym.M-C-3: command:\033[8;25;80t
1134 URxvt.keysym.M-C-4: command:\033[8;48;110t
1135
1136=item builtin:
1137
1138The builtin action is the action that @@RXVT_NAME@@ would execute if no
1139key binding existed for the key combination. The obvious use is to undo
1140the effect of existing bindings. The not so obvious use is to reinstate
1141bindings when another binding overrides too many modifiers.
1142
1073if you overwrite the C<Insert> key you will disable @@RXVT_NAME@@'s 1143For example if you overwrite the C<Insert> key you will disable
1074C<Shift-Insert> mapping. To re-enable that, you can poke "holes" into the 1144@@RXVT_NAME@@'s C<Shift-Insert> mapping. To re-enable that, you can poke
1075user-defined keymap using the C<builtin:> replacement: 1145"holes" into the user-defined keymap using the C<builtin:> replacement:
1076 1146

1081of modifiers. The second line re-establishes the default mapping for 1151of modifiers. The second line re-establishes the default mapping for
1082C<Shift-Insert>. 1152C<Shift-Insert>.
1083 1153
1084The following example will map Control-Meta-1 and Control-Meta-2 to 1154=item builtin-string:
1085the fonts C<suxuseuro> and C<9x15bold>, so you can have some limited
1086font-switching at runtime:
1087 1155
1088 URxvt.keysym.M-C-1: command:\033]50;suxuseuro\007 1156This action is mainly useful to restore string mappings for keys that
1089 URxvt.keysym.M-C-2: command:\033]50;9x15bold\007 1157have predefined actions in @@RXVT_NAME@@. The exact semantics are a bit
1158difficult to explain - basically, this action will send the string to the
1159application that would be sent if @@RXVT_NAME@@ wouldn't have a built-in
1160action for it.
1090 1161
1091Other things are possible, e.g. resizing (see @@RXVT_NAME@@(7) for more 1162An example might make it clearer: @@RXVT_NAME@@ normally pastes the
1092info): 1163selection when you press C<Shift-Insert>. With the following bindings, it
1164would instead emit the (undocumented, but what applications running in the
1165terminal might expect) sequence C<ESC [ 2 $> instead:
1093 1166
1094 URxvt.keysym.M-C-3: command:\033[8;25;80t 1167 URxvt.keysym.S-Insert: builtin-string:
1095 URxvt.keysym.M-C-4: command:\033[8;48;110t 1168 URxvt.keysym.C-S-Insert: builtin:
1169
1170The first line disables the paste functionality for that key
1171combination, and the second reinstates the default behaviour for
1172C<Control-Shift-Insert>, which would otherwise be overridden.
1173
1174Similarly, to let applications gain access to the C<C-M-c> (copy to
1175clipboard) and C<C-M-v> (paste clipboard) key combination, you can do
1176this:
1177
1178 URxvt.keysym.C-S-c: builtin-string:
1179 URxvt.keysym.C-S-v: builtin-string:

1181=item EXTENSION:STRING

1184extension of the same name. The extension will be loaded automatically if
1185neccessary.
1186
1187Not all extensions define key actions, but popular extensions that do

1189own manpages, @@RXVT_NAME@@-selection(1) and @@RXVT_NAME@@-matcher(1),
1190respectively).

1621=head2 ALPHA CHANNEL SUPPORT
1622
1623If Xft support has been compiled in and as long as Xft/Xrender/X don't get
1624their act together, rxvt-unicode will do its own alpha channel management:
1625
1626You can prefix any colour with an opaqueness percentage enclosed in
1627brackets, i.e. C<[percent]>, where C<percent> is a decimal percentage
1628(0-100) that specifies the opacity of the colour, where C<0> is completely
1629transparent and C<100> is completely opaque. For example, C<[50]red> is a
1630half-transparent red, while C<[95]#00ff00> is an almost opaque green. This
1631is the recommended format to specify transparency values, and works with
1632all ways to specify a colour.
1633
1634For complete control, rxvt-unicode also supports
1635C<rgba:rrrr/gggg/bbbb/aaaa> (exactly four hex digits/component) colour
1636specifications, where the additional C<aaaa> component specifies opacity
1637(alpha) values. The minimum value of C<0000> is completely transparent,
1638while C<ffff> is completely opaque). The two example colours from
1639earlier could also be specified as C<rgba:ff00/0000/0000/8000> and
1640C<rgba:0000/ff00/0000/f332>.
1641
1642You probably need to specify B<"-depth 32">, too, to force a visual with
1643alpha channels, and have the luck that your X-server uses ARGB pixel
1644layout, as X is far from just supporting ARGB visuals out of the box, and
1645rxvt-unicode just fudges around.
1646
1647For example, the following selects an almost completely transparent black
1648background, and an almost opaque pink foreground:
1649
1650 @@RXVT_NAME@@ -depth 32 -bg rgba:0000/0000/0000/4444 -fg "[80]pink"
1651
1652When not using a background image, then the interpretation of the
1653alpha channel is up to your compositing manager (most interpret it as
1654transparency of course).
1655
1656When using a background pixmap or pseudo-transparency, then the background
1657colour will always behave as if it were completely transparent (so the
1658background image shows instead), regardless of how it was specified, while
1659other colours will either be transparent as specified (the background
1660image will show through) on servers supporting the RENDER extension, or
1661fully opaque on servers not supporting the RENDER EXTENSION.
1662
1663Please note that due to bugs in Xft, specifying alpha values might result
1664in garbage being displayed when the X-server does not support the RENDER
1665extension.
