1009The format of I<sym> is "I<(modifiers-)key>", where I<modifiers> can be 1065Using this resource, you can map key combinations such as
1010any combination of B<ISOLevel3>, B<AppKeypad>, B<Control>, B<NumLock>, 1066C<Ctrl-Shift-BackSpace> to various actions, such as outputting a different

1013B<2>, B<3>, B<4>, B<5>. 1069extension might provide.
1070
1071The key combination that triggers the action, I<sym>, has the following format:
1072
1073 (modifiers-)key
1074
1075Where I<modifiers> can be any combination of B<ISOLevel3>, B<AppKeypad>,
1076B<Control>, B<NumLock>, B<Shift>, B<Meta>, B<Lock>, B<Mod1>, B<Mod2>,
1077B<Mod3>, B<Mod4>, B<Mod5>, and the abbreviated B<I>, B<K>, B<C>, B<N>,
1078B<S>, B<M>, B<A>, B<L>, B<1>, B<2>, B<3>, B<4>, B<5>.

1016whatever modifier the NumLock key, Meta/Alt keys or ISO Level3 Shift/AltGr 1081whatever modifier the NumLock key, Meta/Alt keys or ISO Level3 Shift/AltGr
1017keys are being mapped. B<AppKeypad> is a synthetic modifier mapped to the 1082keys are being mapped. B<AppKeypad> is a synthetic modifier mapped to the
1018current application keymap mode state. 1083current application keymap mode state.
1019 1084
1020The spellings of I<key> can be obtained by using B<xev>(1) command or 1085Due the the large number of modifier combinations, a key mapping will
1021searching keysym macros from B</usr/X11R6/include/X11/keysymdef.h> and 1086match if I<at least> the specified identifiers are being set, and no other
1087key mappings with those and more bits are being defined. That means that
1088defining a mapping for C<a> will automatically provide definitions for
1089C<Meta-a>, C<Shift-a> and so on, unless some of those are defined mappings
1090themselves. See the C<builtin:> action, below, for a way to work around
1091this when this is a problem.
1092
1093The spelling of I<key> depends on your implementation of X. An easy way to
1094find a key name is to use the B<xev>(1) command. You can find a list by
1095looking for the C<XK_> macros in the B<X11/keysymdef.h> include file (omit
1022omitting the prefix B<XK_>. Alternatively you can specify I<key> by its hex 1096the C<XK_> prefix). Alternatively you can specify I<key> by its hex keysym
1023keysym value (B<0x0000 - 0xFFFF>). Note that the lookup of I<sym>s is not 1097value (B<0x0000 - 0xFFFF>).
1024performed in an exact manner; however, the closest match is assured.
1025 1098
1026I<string> may contain escape values (C<\a>: bell, C<\b>: backspace, 1099As with any resource value, the I<action> string may contain backslash
1027C<\e>, C<\E>: escape, C<\n>: newline, C<\r>: carriage return, C<\t>: tab, 1100escape sequences (C<\n>: newline, C<\\>: backslash, C<\000>: octal
1028C<\000>: octal number) or verbatim control characters (C<^?>: delete, 1101number), see RESOURCES in C<man 7 X> for further details.
1029C<^@>: null, C<^A> ...) and may be enclosed with double quotes so that it
1030can start or end with whitespace.
1031 1102
1032Please note that you need to double the C<\> in resource files, as 1103An action starts with an action prefix that selects a certain type
1033Xlib itself does its own de-escaping (you can use C<\033> instead of 1104of action, followed by a colon. An action string without colons is
1034C<\e> (and so on), which will work with both Xt and @@RXVT_NAME@@'s own 1105interpreted as a literal string to pass to the tty (as if it was
1035processing). 1106prefixed with C<string:>).
1036 1107
1037You can define a range of keysyms in one shot by providing a I<string> 1108The following action prefixes are known - extensions can provide
1038with pattern B<list/PREFIX/MIDDLE/SUFFIX>, where the delimeter `/' 1109additional prefixes:
1039should be a character not used by the strings.
1040 1110
1041Its usage can be demonstrated by an example: 1111=over 4
1042 1112
1043 URxvt.keysym.M-C-0x61: list|\033<M-C-|abc|> 1113=item string:STRING
1044 1114
1045The above line is equivalent to the following three lines: 1115If the I<action> starts with C<string:> (or otherwise contains no colons),
1116then the remaining C<STRING> will be passed to the program running in the
1117terminal. For example, you could replace whatever Shift-Tab outputs by the
1118string C<echo rm -rf /> followed by a newline:
1046 1119
1047 URxvt.keysym.Meta-Control-0x61: \033<M-C-a> 1120 URxvt.keysym.Shift-Tab: string:echo rm -rf /\n
1048 URxvt.keysym.Meta-Control-0x62: \033<M-C-b>
1049 URxvt.keysym.Meta-Control-0x63: \033<M-C-c>
1050 1121
1122This could in theory be used to completely redefine your keymap.
1123
1124=item command:STRING
1125
1051If I<string> takes the form of C<command:STRING>, the specified B<STRING> 1126If I<action> takes the form of C<command:STRING>, the specified B<STRING>
1052is interpreted and executed as @@RXVT_NAME@@'s control sequence. For 1127is interpreted and executed as @@RXVT_NAME@@'s control sequence (basically
1128the opposite of C<string:> - instead of sending it to the program running
1129in the terminal, it will be treated as if it were program output). This is
1130most useful to feed command sequences into @@RXVT_NAME@@.
1131
1053example the following means "change the current locale to C<zh_CN.GBK> 1132For example the following means "change the current locale to C<zh_CN.GBK>

1060manpage. For example, the F<selection> extension (activated via 1139font-switching at runtime:
1061C<@@RXVT_NAME@@ -pe selection>) listens for C<selection:rot13> events:
1062 1140
1063 URxvt.keysym.M-C-c: perl:selection:rot13 1141 URxvt.keysym.M-C-1: command:\033]50;suxuseuro\007
1142 URxvt.keysym.M-C-2: command:\033]50;9x15bold\007
1064 1143
1065Due the the large number of modifier combinations, a defined key mapping 1144Other things are possible, e.g. resizing (see @@RXVT_NAME@@(7) for more
1066will match if at I<at least> the specified identifiers are being set, and 1145info):
1067no other key mappings with those and more bits are being defined. That
1068means that defining a key map for C<a> will automatically provide
1069definitions for C<Meta-a>, C<Shift-a> and so on, unless some of those are defined
1070mappings themselves.
1071 1146
1072Unfortunately, this will override built-in key mappings. For example 1147 URxvt.keysym.M-C-3: command:\033[8;25;80t
1148 URxvt.keysym.M-C-4: command:\033[8;48;110t
1149
1150=item builtin:
1151
1152The builtin action is the action that @@RXVT_NAME@@ would execute if no
1153key binding existed for the key combination. The obvious use is to undo
1154the effect of existing bindings. The not so obvious use is to reinstate
1155bindings when another binding overrides too many modifiers.
1156
1073if you overwrite the C<Insert> key you will disable @@RXVT_NAME@@'s 1157For example if you overwrite the C<Insert> key you will disable
1074C<Shift-Insert> mapping. To re-enable that, you can poke "holes" into the 1158@@RXVT_NAME@@'s C<Shift-Insert> mapping. To re-enable that, you can poke
1075user-defined keymap using the C<builtin:> replacement: 1159"holes" into the user-defined keymap using the C<builtin:> replacement:
1076 1160

1080The first line defines a mapping for C<Insert> and I<any> combination 1164The first line defines a mapping for C<Insert> and I<any> combination
1081of modifiers. The second line re-establishes the default mapping for 1165of modifiers. The second line re-establishes the default mapping for
1082C<Shift-Insert>. 1166C<Shift-Insert>.
1083 1167
1084The following example will map Control-Meta-1 and Control-Meta-2 to 1168=item builtin-string:
1085the fonts C<suxuseuro> and C<9x15bold>, so you can have some limited
1086font-switching at runtime:
1087 1169
1088 URxvt.keysym.M-C-1: command:\033]50;suxuseuro\007 1170This action is mainly useful to restore string mappings for keys that
1089 URxvt.keysym.M-C-2: command:\033]50;9x15bold\007 1171have predefined actions in @@RXVT_NAME@@. The exact semantics are a bit
1172difficult to explain - basically, this action will send the string to the
1173application that would be sent if @@RXVT_NAME@@ wouldn't have a built-in
1174action for it.
1090 1175
1091Other things are possible, e.g. resizing (see @@RXVT_NAME@@(7) for more 1176An example might make it clearer: @@RXVT_NAME@@ normally pastes the
1092info): 1177selection when you press C<Shift-Insert>. With the following bindings, it
1178would instead emit the (undocumented, but what applications running in the
1179terminal might expect) sequence C<ESC [ 2 $> instead:
1093 1180
1094 URxvt.keysym.M-C-3: command:\033[8;25;80t 1181 URxvt.keysym.S-Insert: builtin-string:
1095 URxvt.keysym.M-C-4: command:\033[8;48;110t 1182 URxvt.keysym.C-S-Insert: builtin:
1183
1184The first line disables the paste functionality for that key
1185combination, and the second reinstates the default behaviour for
1186C<Control-Shift-Insert>, which would otherwise be overridden.
1187
1188Similarly, to let applications gain access to the C<C-M-c> (copy to
1189clipboard) and C<C-M-v> (paste clipboard) key combination, you can do
1190this:
1191
1192 URxvt.keysym.C-M-c: builtin-string:
1193 URxvt.keysym.C-M-v: builtin-string:

1195=item EXTENSION:STRING

1198extension of the same name. The extension will be loaded automatically if

1204respectively).

1635=head2 ALPHA CHANNEL SUPPORT
1636
1637If Xft support has been compiled in and as long as Xft/Xrender/X don't get
1638their act together, rxvt-unicode will do its own alpha channel management:
1639
1640You can prefix any colour with an opaqueness percentage enclosed in
1641brackets, i.e. C<[percent]>, where C<percent> is a decimal percentage
1642(0-100) that specifies the opacity of the colour, where C<0> is completely
1643transparent and C<100> is completely opaque. For example, C<[50]red> is a
1644half-transparent red, while C<[95]#00ff00> is an almost opaque green. This
1645is the recommended format to specify transparency values, and works with
1646all ways to specify a colour.
1647
1648For complete control, rxvt-unicode also supports
1649C<rgba:rrrr/gggg/bbbb/aaaa> (exactly four hex digits/component) colour
1650specifications, where the additional C<aaaa> component specifies opacity
1651(alpha) values. The minimum value of C<0000> is completely transparent,
1652while C<ffff> is completely opaque). The two example colours from
1653earlier could also be specified as C<rgba:ff00/0000/0000/8000> and
1654C<rgba:0000/ff00/0000/f332>.
1655
1656You probably need to specify B<"-depth 32">, too, to force a visual with
1657alpha channels, and have the luck that your X-server uses ARGB pixel
1658layout, as X is far from just supporting ARGB visuals out of the box, and
1659rxvt-unicode just fudges around.
1660
1661For example, the following selects an almost completely transparent black
1662background, and an almost opaque pink foreground:
1663
1664 @@RXVT_NAME@@ -depth 32 -bg rgba:0000/0000/0000/4444 -fg "[80]pink"
1665
1666When not using a background image, then the interpretation of the
1667alpha channel is up to your compositing manager (most interpret it as
1668transparency of course).
1669
1670When using a background pixmap or pseudo-transparency, then the background
1671colour will always behave as if it were completely transparent (so the
1672background image shows instead), regardless of how it was specified, while
1673other colours will either be transparent as specified (the background
1674image will show through) on servers supporting the RENDER extension, or
1675fully opaque on servers not supporting the RENDER EXTENSION.
1676
1677Please note that due to bugs in Xft, specifying alpha values might result
1678in garbage being displayed when the X-server does not support the RENDER
1679extension.
