1082 1169
1083The spellings of I<key> can be obtained by using B<xev>(1) command or 1170Due the the large number of modifier combinations, a key mapping will
1084searching keysym macros from B</usr/X11R6/include/X11/keysymdef.h> and 1171match if I<at least> the specified identifiers are being set, and no other
1172key mappings with those and more bits are being defined. That means that
1173defining a mapping for C<a> will automatically provide definitions for
1174C<Meta-a>, C<Shift-a> and so on, unless some of those are defined mappings
1175themselves. See the C<builtin:> action, below, for a way to work around
1176this when this is a problem.
1177
1178The spelling of I<key> depends on your implementation of X. An easy way to
1179find a key name is to use the B<xev>(1) command. You can find a list by
1180looking for the C<XK_> macros in the B<X11/keysymdef.h> include file (omit
1085omitting the prefix B<XK_>. Alternatively you can specify I<key> by its hex 1181the C<XK_> prefix). Alternatively you can specify I<key> by its hex keysym
1086keysym value (B<0x0000 - 0xFFFF>). Note that the lookup of I<sym>s is not 1182value (B<0x0000 - 0xFFFF>).
1087performed in an exact manner; however, the closest match is assured.
1088 1183
1089I<string> may contain escape values (C<\a>: bell, C<\b>: backspace, 1184As with any resource value, the I<action> string may contain backslash
1090C<\e>, C<\E>: escape, C<\n>: newline, C<\r>: carriage return, C<\t>: tab, 1185escape sequences (C<\n>: newline, C<\\>: backslash, C<\000>: octal
1091C<\000>: octal number) or verbatim control characters (C<^?>: delete, 1186number), see RESOURCES in C<man 7 X> for further details.
1092C<^@>: null, C<^A> ...) and may be enclosed with double quotes so that it
1093can start or end with whitespace. B<This feature is deprecated and will
1094be removed>.
1095 1187
1096Please note that you need to double the C<\> in resource files, as 1188An action starts with an action prefix that selects a certain type
1097Xlib itself does its own de-escaping (you can use C<\033> instead of 1189of action, followed by a colon. An action string without colons is
1098C<\e> (and so on), which will work with both Xt and @@RXVT_NAME@@'s own 1190interpreted as a literal string to pass to the tty (as if it was
1099processing). 1191prefixed with C<string:>).
1100 1192
1101You can define a range of keysyms in one shot by providing a I<string> 1193The following action prefixes are known - extensions can provide
1102with pattern B<list/PREFIX/MIDDLE/SUFFIX>, where the delimiter `/' 1194additional prefixes:
1195
1196=over
1197
1198=item string:STRING
1199
1200If the I<action> starts with C<string:> (or otherwise contains no colons),
1201then the remaining C<STRING> will be passed to the program running in the
1202terminal. For example, you could replace whatever Shift-Tab outputs by the
1203string C<echo rm -rf /> followed by a newline:
1204
1205 URxvt.keysym.Shift-Tab: string:echo rm -rf /\n
1206
1207This could in theory be used to completely redefine your keymap.
1208
1209In addition, for actions of this type, you can define a range of
1210keysyms in one shot by loading the C<keysym-list> perl extension and
1211providing an I<action> with pattern B<list/PREFIX/MIDDLE/SUFFIX>, where
1103should be a character not used by the strings. 1212the delimiter `/' should be a character not used by the strings.
1104 1213
1105Its usage can be demonstrated by an example: 1214Its usage can be demonstrated by an example:

1228the opposite of C<string:> - instead of sending it to the program running

1230most useful to feed command sequences into @@RXVT_NAME@@.

1124manpage. For example, the F<selection> extension (activated via 1239font-switching at runtime:
1125C<@@RXVT_NAME@@ -pe selection>) listens for C<selection:rot13> events:
1126 1240
1127 URxvt.keysym.M-C-c: perl:selection:rot13 1241 URxvt.keysym.M-C-1: command:\033]50;suxuseuro\007
1242 URxvt.keysym.M-C-2: command:\033]50;9x15bold\007
1128 1243
1129Due the the large number of modifier combinations, a defined key mapping 1244Other things are possible, e.g. resizing (see @@RXVT_NAME@@(7) for more
1130will match if at I<at least> the specified identifiers are being set, and 1245info):
1131no other key mappings with those and more bits are being defined. That
1132means that defining a key map for C<a> will automatically provide
1133definitions for C<Meta-a>, C<Shift-a> and so on, unless some of those are defined
1134mappings themselves.
1135 1246
1136Unfortunately, this will override built-in key mappings. For example 1247 URxvt.keysym.M-C-3: command:\033[8;25;80t
1248 URxvt.keysym.M-C-4: command:\033[8;48;110t
1249
1250=item builtin:
1251
1252The builtin action is the action that @@RXVT_NAME@@ would execute if no
1253key binding existed for the key combination. The obvious use is to undo
1254the effect of existing bindings. The not so obvious use is to reinstate
1255bindings when another binding overrides too many modifiers.
1256
1137if you overwrite the C<Insert> key you will disable @@RXVT_NAME@@'s 1257For example if you overwrite the C<Insert> key you will disable
1138C<Shift-Insert> mapping. To re-enable that, you can poke "holes" into the 1258@@RXVT_NAME@@'s C<Shift-Insert> mapping. To re-enable that, you can poke
1139user-defined keymap using the C<builtin:> replacement: 1259"holes" into the user-defined keymap using the C<builtin:> replacement:

1145of modifiers. The second line re-establishes the default mapping for 1265of modifiers. The second line re-establishes the default mapping for
1146C<Shift-Insert>. 1266C<Shift-Insert>.
1147 1267
1148The following example will map Control-Meta-1 and Control-Meta-2 to 1268=item builtin-string:
1149the fonts C<suxuseuro> and C<9x15bold>, so you can have some limited
1150font-switching at runtime:
1151 1269
1152 URxvt.keysym.M-C-1: command:\033]50;suxuseuro\007 1270This action is mainly useful to restore string mappings for keys that
1153 URxvt.keysym.M-C-2: command:\033]50;9x15bold\007 1271have predefined actions in @@RXVT_NAME@@. The exact semantics are a bit
1272difficult to explain - basically, this action will send the string to the
1273application that would be sent if @@RXVT_NAME@@ wouldn't have a built-in
1274action for it.
1154 1275
1155Other things are possible, e.g. resizing (see @@RXVT_NAME@@(7) for more 1276An example might make it clearer: @@RXVT_NAME@@ normally pastes the
1156info): 1277selection when you press C<Shift-Insert>. With the following bindings, it
1278would instead emit the (undocumented, but what applications running in the
1279terminal might expect) sequence C<ESC [ 2 $> instead:
1157 1280
1158 URxvt.keysym.M-C-3: command:\033[8;25;80t 1281 URxvt.keysym.S-Insert: builtin-string:
1159 URxvt.keysym.M-C-4: command:\033[8;48;110t 1282 URxvt.keysym.C-S-Insert: builtin:
1283
1284The first line disables the paste functionality for that key
1285combination, and the second reinstates the default behaviour for
1286C<Control-Shift-Insert>, which would otherwise be overridden.
1287
1288Similarly, to let applications gain access to the C<C-M-c> (copy to
1289clipboard) and C<C-M-v> (paste clipboard) key combination, you can do
1290this:
1291
1292 URxvt.keysym.C-M-c: builtin-string:
1293 URxvt.keysym.C-M-v: builtin-string:

1299be loaded automatically if necessary.

1574number of 24-bit colours that can be used is limited: an internal 7x7x5 (256
1575colour mode) or 6x6x4 (88 colour mode) colour cube is used to index into the
