1145The format of I<sym> is "I<(modifiers-)key>", where I<modifiers> can be 1051Using this resource, you can map key combinations such as
1146any combination of B<ISOLevel3>, B<AppKeypad>, B<Control>, B<NumLock>, 1052C<Ctrl-Shift-BackSpace> to various actions, such as outputting a different

1149B<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>.

1153keys 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
1154current application keymap mode state. 1069current application keymap mode state.
1155 1070
1156The 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
1157searching 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
1158omitting 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
1159keysym value (B<0x0000 - 0xFFFF>). Note that the lookup of I<sym>s is not 1083value (B<0x0000 - 0xFFFF>).
1160performed in an exact manner; however, the closest match is assured.
1161 1084
1162I<string> may contain escape values (C<\n>: newline, C<\000>: octal 1085As with any resource value, the I<action> string may contain backslash
1086escape sequences (C<\n>: newline, C<\\>: backslash, C<\000>: octal
1163number), see RESOURCES in C<man 7 X> for further details. 1087number), see RESOURCES in C<man 7 X> for further details.
1164 1088
1089An action starts with an action prefix that selects a certain type
1090of action, followed by a colon. An action strings without colons is
1091interpreted as a literal string to pass to the tty (as if they were
1092prefixed with C<string:>).
1093
1094The following action prefixes are known - extensions can provide
1095additional prefixes:
1096
1097=over 4
1098
1099=item string:STRING
1100
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:
1105
1106 URxvt.keysym.Shift-Tab: string:echo rm -rf /\n
1107
1108This could in theory be used to completely redefine your keymap.
1109
1110=item command:STRING
1111
1112If I<action> takes the form of C<command:STRING>, the specified B<STRING>
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
1118For example the following means "change the current locale to C<zh_CN.GBK>
1119when Control-Meta-c is being pressed":
1120
1121 URxvt.keysym.M-C-c: command:\033]701;zh_CN.GBK\007
1122
1123The following example will map Control-Meta-1 and Control-Meta-2 to
1124the fonts C<suxuseuro> and C<9x15bold>, so you can have some limited
1125font-switching at runtime:
1126
1127 URxvt.keysym.M-C-1: command:\033]50;suxuseuro\007
1128 URxvt.keysym.M-C-2: command:\033]50;9x15bold\007
1129
1130Other things are possible, e.g. resizing (see @@RXVT_NAME@@(7) for more
1131info):
1132
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
1143For example if you overwrite the C<Insert> key you will disable
1144@@RXVT_NAME@@'s C<Shift-Insert> mapping. To re-enable that, you can poke
1145"holes" into the user-defined keymap using the C<builtin:> replacement:
1146
1147 URxvt.keysym.Insert: <my insert key sequence>
1148 URxvt.keysym.S-Insert: builtin:
1149
1150The first line defines a mapping for C<Insert> and I<any> combination
1151of modifiers. The second line re-establishes the default mapping for
1152C<Shift-Insert>.
1153
1154=item builtin-string:
1155
1156This action is mainly useful to restore string mappings for keys that
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.
1161
1162An example might make it clearer: @@RXVT_NAME@@ normally pastes the
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:
1166
1167 URxvt.keysym.S-Insert: builtin-string:
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:
1180
1181=item EXTENSION:STRING
1182
1183An action of this form passes the B<STRING> to the @@RXVT_NAME@@perl(3)
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
1188include the I<selection> and I<matcher> extensions (documented in their
1189own manpages, @@RXVT_NAME@@-selection(1) and @@RXVT_NAME@@-matcher(1),
1190respectively).
1191
1192From the silly examples department, this will rot13-"encrypt"
1193@@RXVT_NAME@@'s selection when Alt-Control-c is pressed on typical PC
1194keyboards:
1195
1196 URxvt.keysym.M-C-c: selection:rot13
1197
1198=item perl:STRING
1199
1200This is a deprecated way of passing key mappings to perl extensions. It is
1201still supported, but should not be used anymore.
1202
1203=back
1204
1165You can define a range of keysyms in one shot by providing a I<string> 1205In addition, you can define a range of keysyms in one shot by loading
1206the C<keysym-list> perl extension and providing a I<string> with pattern
1166with pattern B<list/PREFIX/MIDDLE/SUFFIX>, where the delimiter `/' 1207B<list/PREFIX/MIDDLE/SUFFIX>, where the delimiter `/' should be a
1167should be a character not used by the strings. 1208character not used by the strings.
1168 1209
1169Its usage can be demonstrated by an example: 1210Its usage can be demonstrated by an example:
1170 1211
1171 URxvt.keysym.M-C-0x61: list|\033<|abc|> 1212 URxvt.keysym.M-C-0x61: list|\033<|abc|>
1172 1213
1173The above line is equivalent to the following three lines: 1214The above line is equivalent to the following three lines:
1174 1215
1175 URxvt.keysym.Meta-Control-0x61: \033<a> 1216 URxvt.keysym.Meta-Control-0x61: \033<a>
1176 URxvt.keysym.Meta-Control-0x62: \033<b> 1217 URxvt.keysym.Meta-Control-0x62: \033<b>
1177 URxvt.keysym.Meta-Control-0x63: \033<c> 1218 URxvt.keysym.Meta-Control-0x63: \033<c>
1178
1179If I<string> takes the form of C<command:STRING>, the specified B<STRING>
1180is interpreted and executed as @@RXVT_NAME@@'s control sequence. For
1181example the following means "change the current locale to C<zh_CN.GBK>
1182when Control-Meta-c is being pressed":
1183
1184 URxvt.keysym.M-C-c: command:\033]701;zh_CN.GBK\007
1185
1186If I<string> takes the form C<perl:STRING>, then the specified B<STRING>
1187is passed to the C<on_user_command> perl handler. See the @@RXVT_NAME@@perl(3)
1188manpage. For example, the F<selection> extension (activated via
1189C<@@RXVT_NAME@@ -pe selection>) listens for C<selection:rot13> events:
1190
1191 URxvt.keysym.M-C-c: perl:selection:rot13
1192
1193Due the the large number of modifier combinations, a defined key mapping
1194will match if I<at least> the specified identifiers are being set, and
1195no other key mappings with those and more bits are being defined. That
1196means that defining a key map for C<a> will automatically provide
1197definitions for C<Meta-a>, C<Shift-a> and so on, unless some of those are defined
1198mappings themselves.
1199
1200Unfortunately, this will override built-in key mappings. For example
1201if you overwrite the C<Insert> key you will disable @@RXVT_NAME@@'s
1202C<Shift-Insert> mapping. To re-enable that, you can poke "holes" into the
1203user-defined keymap using the C<builtin:> replacement:
1204
1205 URxvt.keysym.Insert: <my insert key sequence>
1206 URxvt.keysym.S-Insert: builtin:
1207
1208The first line defines a mapping for C<Insert> and I<any> combination
1209of modifiers. The second line re-establishes the default mapping for
1210C<Shift-Insert>.
1211
1212The following example will map Control-Meta-1 and Control-Meta-2 to
1213the fonts C<suxuseuro> and C<9x15bold>, so you can have some limited
1214font-switching at runtime:
1215
1216 URxvt.keysym.M-C-1: command:\033]50;suxuseuro\007
1217 URxvt.keysym.M-C-2: command:\033]50;9x15bold\007
1218
1219Other things are possible, e.g. resizing (see @@RXVT_NAME@@(7) for more
1220info):

1222 URxvt.keysym.M-C-3: command:\033[8;25;80t
