1050 1073
1051The format of I<sym> is "I<(modifiers-)key>", where I<modifiers> can be 1074Using this resource, you can map key combinations such as
1052any combination of B<ISOLevel3>, B<AppKeypad>, B<Control>, B<NumLock>, 1075C<Ctrl-Shift-BackSpace> to various actions, such as outputting a different
1053B<Shift>, B<Meta>, B<Lock>, B<Mod1>, B<Mod2>, B<Mod3>, B<Mod4>, B<Mod5>, 1076string than would normally result from that combination, making the

1055B<2>, B<3>, B<4>, B<5>. 1078extension might provide.
1079
1080The key combination that triggers the action, I<sym>, has the following format:
1081
1082 (modifiers-)key
1083
1084Where I<modifiers> can be any combination of B<ISOLevel3>, B<AppKeypad>,
1085B<Control>, B<NumLock>, B<Shift>, B<Meta>, B<Lock>, B<Mod1>, B<Mod2>,
1086B<Mod3>, B<Mod4>, B<Mod5>, and the abbreviated B<I>, B<K>, B<C>, B<N>,
1087B<S>, B<M>, B<A>, B<L>, B<1>, B<2>, B<3>, B<4>, B<5>.
1056 1088
1057The B<NumLock>, B<Meta> and B<ISOLevel3> modifiers are usually aliased to 1089The B<NumLock>, B<Meta> and B<ISOLevel3> modifiers are usually aliased to
1058whatever modifier the NumLock key, Meta/Alt keys or ISO Level3 Shift/AltGr 1090whatever modifier the NumLock key, Meta/Alt keys or ISO Level3 Shift/AltGr
1059keys are being mapped. B<AppKeypad> is a synthetic modifier mapped to the 1091keys are being mapped. B<AppKeypad> is a synthetic modifier mapped to the
1060current application keymap mode state. 1092current application keymap mode state.
1061 1093
1062The spellings of I<key> can be obtained by using B<xev>(1) command or 1094Due the the large number of modifier combinations, a key mapping will
1063searching keysym macros from B</usr/X11R6/include/X11/keysymdef.h> and 1095match if I<at least> the specified identifiers are being set, and no other
1096key mappings with those and more bits are being defined. That means that
1097defining a mapping for C<a> will automatically provide definitions for
1098C<Meta-a>, C<Shift-a> and so on, unless some of those are defined mappings
1099themselves. See the C<builtin:> action, below, for a way to work around
1100this when this is a problem.
1101
1102The spelling of I<key> depends on your implementation of X. An easy way to
1103find a key name is to use the B<xev>(1) command. You can find a list by
1104looking for the C<XK_> macros in the B<X11/keysymdef.h> include file (omit
1064omitting the prefix B<XK_>. Alternatively you can specify I<key> by its hex 1105the C<XK_> prefix). Alternatively you can specify I<key> by its hex keysym
1065keysym value (B<0x0000 - 0xFFFF>). Note that the lookup of I<sym>s is not 1106value (B<0x0000 - 0xFFFF>).
1066performed in an exact manner; however, the closest match is assured.
1067 1107
1068I<string> may contain escape values (C<\n>: newline, C<\000>: octal 1108As with any resource value, the I<action> string may contain backslash
1109escape sequences (C<\n>: newline, C<\\>: backslash, C<\000>: octal
1069number), see RESOURCES in C<man 7 X> for further details. 1110number), see RESOURCES in C<man 7 X> for further details.
1070 1111
1071You can define a range of keysyms in one shot by 1112An action starts with an action prefix that selects a certain type
1072loading the C<keysym-list> perl extension and providing a I<string> 1113of action, followed by a colon. An action string without colons is
1073with pattern B<list/PREFIX/MIDDLE/SUFFIX>, where the delimiter `/' 1114interpreted as a literal string to pass to the tty (as if it was
1115prefixed with C<string:>).
1116
1117The following action prefixes are known - extensions can provide
1118additional prefixes:
1119
1120=over 4
1121
1122=item string:STRING
1123
1124If the I<action> starts with C<string:> (or otherwise contains no colons),
1125then the remaining C<STRING> will be passed to the program running in the
1126terminal. For example, you could replace whatever Shift-Tab outputs by the
1127string C<echo rm -rf /> followed by a newline:
1128
1129 URxvt.keysym.Shift-Tab: string:echo rm -rf /\n
1130
1131This could in theory be used to completely redefine your keymap.
1132
1133In addition, for actions of this type, you can define a range of
1134keysyms in one shot by loading the C<keysym-list> perl extension and
1135providing an I<action> with pattern B<list/PREFIX/MIDDLE/SUFFIX>, where
1074should be a character not used by the strings. 1136the delimiter `/' should be a character not used by the strings.
1075 1137
1076Its usage can be demonstrated by an example: 1138Its usage can be demonstrated by an example:
1077 1139
1078 URxvt.keysym.M-C-0x61: list|\033<|abc|> 1140 URxvt.keysym.M-C-0x61: list|\033<|abc|>
1079 1141
1080The above line is equivalent to the following three lines: 1142The above line is equivalent to the following three lines:
1081 1143
1082 URxvt.keysym.Meta-Control-0x61: \033<a> 1144 URxvt.keysym.Meta-Control-0x61: string:\033<a>
1083 URxvt.keysym.Meta-Control-0x62: \033<b> 1145 URxvt.keysym.Meta-Control-0x62: string:\033<b>
1084 URxvt.keysym.Meta-Control-0x63: \033<c> 1146 URxvt.keysym.Meta-Control-0x63: string:\033<c>
1085 1147
1148=item command:STRING
1149
1086If I<string> takes the form of C<command:STRING>, the specified B<STRING> 1150If I<action> takes the form of C<command:STRING>, the specified B<STRING>
1087is interpreted and executed as @@RXVT_NAME@@'s control sequence. For 1151is interpreted and executed as @@RXVT_NAME@@'s control sequence (basically
1152the opposite of C<string:> - instead of sending it to the program running
1153in the terminal, it will be treated as if it were program output). This is
1154most useful to feed command sequences into @@RXVT_NAME@@.
1155
1088example the following means "change the current locale to C<zh_CN.GBK> 1156For example the following means "change the current locale to C<zh_CN.GBK>
1089when Control-Meta-c is being pressed": 1157when Control-Meta-c is being pressed":

1092 1160
1093If I<string> takes the form C<perl:STRING>, then the specified B<STRING> 1161The following example will map Control-Meta-1 and Control-Meta-2 to
1094is passed to the C<on_user_command> perl handler. See the @@RXVT_NAME@@perl(3) 1162the fonts C<suxuseuro> and C<9x15bold>, so you can have some limited
1095manpage. For example, the F<selection> extension (activated via 1163font-switching at runtime:
1096C<@@RXVT_NAME@@ -pe selection>) listens for C<selection:rot13> events:
1097 1164
1098 URxvt.keysym.M-C-c: perl:selection:rot13 1165 URxvt.keysym.M-C-1: command:\033]50;suxuseuro\007
1166 URxvt.keysym.M-C-2: command:\033]50;9x15bold\007
1099 1167
1100Due the the large number of modifier combinations, a defined key mapping 1168Other things are possible, e.g. resizing (see @@RXVT_NAME@@(7) for more
1101will match if I<at least> the specified identifiers are being set, and 1169info):
1102no other key mappings with those and more bits are being defined. That
1103means that defining a key map for C<a> will automatically provide
1104definitions for C<Meta-a>, C<Shift-a> and so on, unless some of those are defined
1105mappings themselves.
1106 1170
1107Unfortunately, this will override built-in key mappings. For example 1171 URxvt.keysym.M-C-3: command:\033[8;25;80t
1172 URxvt.keysym.M-C-4: command:\033[8;48;110t
1173
1174=item builtin:
1175
1176The builtin action is the action that @@RXVT_NAME@@ would execute if no
1177key binding existed for the key combination. The obvious use is to undo
1178the effect of existing bindings. The not so obvious use is to reinstate
1179bindings when another binding overrides too many modifiers.
1180
1108if you overwrite the C<Insert> key you will disable @@RXVT_NAME@@'s 1181For example if you overwrite the C<Insert> key you will disable
1109C<Shift-Insert> mapping. To re-enable that, you can poke "holes" into the 1182@@RXVT_NAME@@'s C<Shift-Insert> mapping. To re-enable that, you can poke
1110user-defined keymap using the C<builtin:> replacement: 1183"holes" into the user-defined keymap using the C<builtin:> replacement:
1111 1184
1112 URxvt.keysym.Insert: <my insert key sequence> 1185 URxvt.keysym.Insert: <my insert key sequence>
1113 URxvt.keysym.S-Insert: builtin: 1186 URxvt.keysym.S-Insert: builtin:
1114 1187
1115The first line defines a mapping for C<Insert> and I<any> combination 1188The first line defines a mapping for C<Insert> and I<any> combination
1116of modifiers. The second line re-establishes the default mapping for 1189of modifiers. The second line re-establishes the default mapping for
1117C<Shift-Insert>. 1190C<Shift-Insert>.
1118 1191
1119The following example will map Control-Meta-1 and Control-Meta-2 to 1192=item builtin-string:
1120the fonts C<suxuseuro> and C<9x15bold>, so you can have some limited
1121font-switching at runtime:
1122 1193
1123 URxvt.keysym.M-C-1: command:\033]50;suxuseuro\007 1194This action is mainly useful to restore string mappings for keys that
1124 URxvt.keysym.M-C-2: command:\033]50;9x15bold\007 1195have predefined actions in @@RXVT_NAME@@. The exact semantics are a bit
1196difficult to explain - basically, this action will send the string to the
1197application that would be sent if @@RXVT_NAME@@ wouldn't have a built-in
1198action for it.
1125 1199
1126Other things are possible, e.g. resizing (see @@RXVT_NAME@@(7) for more 1200An example might make it clearer: @@RXVT_NAME@@ normally pastes the
1127info): 1201selection when you press C<Shift-Insert>. With the following bindings, it
1202would instead emit the (undocumented, but what applications running in the
1203terminal might expect) sequence C<ESC [ 2 $> instead:
1128 1204
1129 URxvt.keysym.M-C-3: command:\033[8;25;80t 1205 URxvt.keysym.S-Insert: builtin-string:
1130 URxvt.keysym.M-C-4: command:\033[8;48;110t 1206 URxvt.keysym.C-S-Insert: builtin:
1207
1208The first line disables the paste functionality for that key
1209combination, and the second reinstates the default behaviour for
1210C<Control-Shift-Insert>, which would otherwise be overridden.
1211
1212Similarly, to let applications gain access to the C<C-M-c> (copy to
1213clipboard) and C<C-M-v> (paste clipboard) key combination, you can do
1214this:
1215
1216 URxvt.keysym.C-M-c: builtin-string:
1217 URxvt.keysym.C-M-v: builtin-string:
1218
1219=item EXTENSION:STRING

1221An action of this form invokes the action B<STRING>, if any, provided
1222by the @@RXVT_NAME@@perl(3) extension B<EXTENSION>. The extension will
1223be loaded automatically if necessary.
1224
1225Not all extensions define actions, but popular extensions that do
1226include the I<selection> and I<matcher> extensions (documented in their
1227own manpages, @@RXVT_NAME@@-selection(1) and @@RXVT_NAME@@-matcher(1),
1228respectively).

1603number of 24-bit colours that can be used is limited: an internal 7x7x5 (256
1604colour mode) or 6x6x4 (88 colour mode) colour cube is used to index into the
160524-bit colour space. When indexing collisions happen, the nearest old colour in
1606the cube will be adapted to the new 24-bit RGB colour. That means one cannot
1607use many similar 24-bit colours. It's typically not a problem in common
1608scenarios.
