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>,

1081 1070
1082The 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
1083searching 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
1084omitting 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
1085keysym value (B<0x0000 - 0xFFFF>). Note that the lookup of I<sym>s is not 1083value (B<0x0000 - 0xFFFF>).
1086performed in an exact manner; however, the closest match is assured.
1087 1084
1088I<string> may contain escape values (C<\a>: bell, C<\b>: backspace, 1085As with any resource value, the I<action> string may contain backslash
1089C<\e>, C<\E>: escape, C<\n>: newline, C<\r>: carriage return, C<\t>: tab, 1086escape sequences (C<\n>: newline, C<\\>: backslash, C<\000>: octal

1091C<^@>: null, C<^A> ...) and may be enclosed with double quotes so that it
1092can start or end with whitespace. B<This feature is deprecated and will
1093be removed>.
1094 1088
1095Please note that you need to double the C<\> in resource files, as 1089An action starts with an action prefix that selects a certain type
1096Xlib itself does its own de-escaping (you can use C<\033> instead of 1090of action, followed by a colon. An action strings without colons is

1098processing). 1092prefixed with C<string:>).
1099 1093
1100You can define a range of keysyms in one shot by providing a I<string> 1094The following action prefixes are known - extensions can provide
1101with pattern B<list/PREFIX/MIDDLE/SUFFIX>, where the delimiter `/' 1095additional prefixes:
1102should be a character not used by the strings.
1103 1096
1104Its usage can be demonstrated by an example: 1097=over 4
1105 1098
1106 URxvt.keysym.M-C-0x61: list|\033<M-C-|abc|> 1099=item string:STRING
1107 1100
1108The 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:
1109 1105
1110 URxvt.keysym.Meta-Control-0x61: \033<M-C-a> 1106 URxvt.keysym.Shift-Tab: string:echo rm -rf /\n
1111 URxvt.keysym.Meta-Control-0x62: \033<M-C-b>
1112 URxvt.keysym.Meta-Control-0x63: \033<M-C-c>
1113 1107
1108This could in theory be used to completely redefine your keymap.

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@@.

1123manpage. For example, the F<selection> extension (activated via 1125font-switching at runtime:
1124C<@@RXVT_NAME@@ -pe selection>) listens for C<selection:rot13> events:
1125 1126
1126 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
1127 1129
1128Due the the large number of modifier combinations, a defined key mapping 1130Other things are possible, e.g. resizing (see @@RXVT_NAME@@(7) for more
1129will match if at I<at least> the specified identifiers are being set, and 1131info):
1130no other key mappings with those and more bits are being defined. That
1131means that defining a key map for C<a> will automatically provide
1132definitions for C<Meta-a>, C<Shift-a> and so on, unless some of those are defined
1133mappings themselves.
1134 1132
1135Unfortunately, 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
1136if you overwrite the C<Insert> key you will disable @@RXVT_NAME@@'s 1143For example if you overwrite the C<Insert> key you will disable
1137C<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
1138user-defined keymap using the C<builtin:> replacement: 1145"holes" into the user-defined keymap using the C<builtin:> replacement:
1139 1146
1140 URxvt.keysym.Insert: <my insert key sequence> 1147 URxvt.keysym.Insert: <my insert key sequence>

1143The first line defines a mapping for C<Insert> and I<any> combination 1150The first line defines a mapping for C<Insert> and I<any> combination
1144of modifiers. The second line re-establishes the default mapping for 1151of modifiers. The second line re-establishes the default mapping for
1145C<Shift-Insert>. 1152C<Shift-Insert>.
1146 1153
1147The following example will map Control-Meta-1 and Control-Meta-2 to 1154=item builtin-string:
1148the fonts C<suxuseuro> and C<9x15bold>, so you can have some limited
1149font-switching at runtime:
1150 1155
1151 URxvt.keysym.M-C-1: command:\033]50;suxuseuro\007 1156This action is mainly useful to restore string mappings for keys that
1152 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.
1153 1161
1154Other things are possible, e.g. resizing (see @@RXVT_NAME@@(7) for more 1162An example might make it clearer: @@RXVT_NAME@@ normally pastes the
1155info): 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:
1156 1166
1157 URxvt.keysym.M-C-3: command:\033[8;25;80t 1167 URxvt.keysym.S-Insert: builtin-string:
1158 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
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

1204
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
1207B<list/PREFIX/MIDDLE/SUFFIX>, where the delimiter `/' should be a
1208character not used by the strings.
