1146 1050
1147The format of I<sym> is "I<(modifiers-)key>", where I<modifiers> can be 1051Using this resource, you can map key combinations such as
1148any combination of B<ISOLevel3>, B<AppKeypad>, B<Control>, B<NumLock>, 1052C<Ctrl-Shift-BackSpace> to various actions, such as outputting a different
1149B<Shift>, B<Meta>, B<Lock>, B<Mod1>, B<Mod2>, B<Mod3>, B<Mod4>, B<Mod5>, 1053string than would normally result from that combination, making the

1151B<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>.
1152 1065
1153The B<NumLock>, B<Meta> and B<ISOLevel3> modifiers are usually aliased to 1066The B<NumLock>, B<Meta> and B<ISOLevel3> modifiers are usually aliased to
1154whatever 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
1155keys 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
1156current application keymap mode state. 1069current application keymap mode state.
1157 1070
1158The 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
1159searching 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
1160omitting 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
1161keysym value (B<0x0000 - 0xFFFF>). Note that the lookup of I<sym>s is not 1083value (B<0x0000 - 0xFFFF>).
1162performed in an exact manner; however, the closest match is assured.
1163 1084
1164I<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
1165number), see RESOURCES in C<man 7 X> for further details. 1087number), see RESOURCES in C<man 7 X> for further details.
1166 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
1167You 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
1168with pattern B<list/PREFIX/MIDDLE/SUFFIX>, where the delimiter `/' 1207B<list/PREFIX/MIDDLE/SUFFIX>, where the delimiter `/' should be a
1169should be a character not used by the strings. 1208character not used by the strings.
1170 1209
1171Its usage can be demonstrated by an example: 1210Its usage can be demonstrated by an example:
1172 1211
1173 URxvt.keysym.M-C-0x61: list|\033<|abc|> 1212 URxvt.keysym.M-C-0x61: list|\033<|abc|>
1174 1213
1175The above line is equivalent to the following three lines: 1214The above line is equivalent to the following three lines:
1176 1215
1177 URxvt.keysym.Meta-Control-0x61: \033<a> 1216 URxvt.keysym.Meta-Control-0x61: \033<a>
1178 URxvt.keysym.Meta-Control-0x62: \033<b> 1217 URxvt.keysym.Meta-Control-0x62: \033<b>
1179 URxvt.keysym.Meta-Control-0x63: \033<c> 1218 URxvt.keysym.Meta-Control-0x63: \033<c>
1180
1181If I<string> takes the form of C<command:STRING>, the specified B<STRING>
1182is interpreted and executed as @@RXVT_NAME@@'s control sequence. For
1183example the following means "change the current locale to C<zh_CN.GBK>
1184when Control-Meta-c is being pressed":
1185
1186 URxvt.keysym.M-C-c: command:\033]701;zh_CN.GBK\007
1187
1188If I<string> takes the form C<perl:STRING>, then the specified B<STRING>
1189is passed to the C<on_user_command> perl handler. See the @@RXVT_NAME@@perl(3)
1190manpage. For example, the F<selection> extension (activated via
1191C<@@RXVT_NAME@@ -pe selection>) listens for C<selection:rot13> events:
1192
1193 URxvt.keysym.M-C-c: perl:selection:rot13
1194
1195Due the the large number of modifier combinations, a defined key mapping
1196will match if I<at least> the specified identifiers are being set, and
1197no other key mappings with those and more bits are being defined. That
1198means that defining a key map for C<a> will automatically provide
1199definitions for C<Meta-a>, C<Shift-a> and so on, unless some of those are defined
1200mappings themselves.
1201
1202Unfortunately, this will override built-in key mappings. For example
1203if you overwrite the C<Insert> key you will disable @@RXVT_NAME@@'s
1204C<Shift-Insert> mapping. To re-enable that, you can poke "holes" into the
1205user-defined keymap using the C<builtin:> replacement:
1206
1207 URxvt.keysym.Insert: <my insert key sequence>
1208 URxvt.keysym.S-Insert: builtin:
1209
1210The first line defines a mapping for C<Insert> and I<any> combination
1211of modifiers. The second line re-establishes the default mapping for
1212C<Shift-Insert>.
1213
1214The following example will map Control-Meta-1 and Control-Meta-2 to
1215the fonts C<suxuseuro> and C<9x15bold>, so you can have some limited
1216font-switching at runtime:
1217
1218 URxvt.keysym.M-C-1: command:\033]50;suxuseuro\007
1219 URxvt.keysym.M-C-2: command:\033]50;9x15bold\007
1220
1221Other things are possible, e.g. resizing (see @@RXVT_NAME@@(7) for more
1222info):

1224 URxvt.keysym.M-C-3: command:\033[8;25;80t
