1081
1082 (modifiers-)key
1083
1084Where I<modifiers> can be any combination of the following full or
1085abbreviated modifier names:

1019 1108
1020The spellings of I<key> can be obtained by using B<xev>(1) command or 1109Due the the large number of modifier combinations, a key mapping will
1021searching keysym macros from B</usr/X11R6/include/X11/keysymdef.h> and 1110match if I<at least> the specified identifiers are being set, and no other
1111key mappings with those and more bits are being defined. That means that
1112defining a mapping for C<a> will automatically provide definitions for
1113C<Meta-a>, C<Shift-a> and so on, unless some of those are defined mappings
1114themselves. See the C<builtin:> action, below, for a way to work around
1115this when this is a problem.
1116
1117The spelling of I<key> depends on your implementation of X. An easy way to
1118find a key name is to use the B<xev>(1) command. You can find a list by
1119looking 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 1120the 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 1121value (B<0x0000 - 0xFFFF>).
1024performed in an exact manner; however, the closest match is assured.
1025 1122
1026I<string> may contain escape values (C<\a>: bell, C<\b>: backspace, 1123As 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, 1124escape sequences (C<\n>: newline, C<\\>: backslash, C<\000>: octal
1028C<\000>: octal number) or verbatim control characters (C<^?>: delete, 1125number), 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 1126
1032Please note that you need to double the C<\> in resource files, as 1127An 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 1128of 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 1129interpreted as a literal string to pass to the tty (as if it was
1035processing). 1130prefixed with C<string:>).
1036 1131
1037You can define a range of keysyms in one shot by providing a I<string> 1132The following action prefixes are known - extensions can provide
1038with pattern B<list/PREFIX/MIDDLE/SUFFIX>, where the delimeter `/' 1133additional prefixes:
1134
1135=over 4
1136
1137=item string:STRING
1138
1139If the I<action> starts with C<string:> (or otherwise contains no colons),
1140then the remaining C<STRING> will be passed to the program running in the
1141terminal. For example, you could replace whatever Shift-Tab outputs by the
1142string C<echo rm -rf /> followed by a newline:
1143
1144 URxvt.keysym.Shift-Tab: string:echo rm -rf /\n
1145
1146This could in theory be used to completely redefine your keymap.
1147
1148In addition, for actions of this type, you can define a range of
1149keysyms in one shot by loading the C<keysym-list> perl extension and
1150providing an I<action> with pattern B<list/PREFIX/MIDDLE/SUFFIX>, where
1039should be a character not used by the strings. 1151the delimiter `/' should be a character not used by the strings.
1040 1152
1041Its usage can be demonstrated by an example: 1153Its usage can be demonstrated by an example:
1042 1154

1167the opposite of C<string:> - instead of sending it to the program running

1169most useful to feed command sequences into @@RXVT_NAME@@.

1060manpage. For example, the F<selection> extension (activated via 1178font-switching at runtime:
1061C<@@RXVT_NAME@@ -pe selection>) listens for C<selection:rot13> events:
1062 1179
1063 URxvt.keysym.M-C-c: perl:selection:rot13 1180 URxvt.keysym.M-C-1: command:\033]50;suxuseuro\007
1181 URxvt.keysym.M-C-2: command:\033]50;9x15bold\007
1064 1182
1065Due the the large number of modifier combinations, a defined key mapping 1183Other 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 1184info):
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 1185
1072Unfortunately, this will override built-in key mappings. For example 1186 URxvt.keysym.M-C-3: command:\033[8;25;80t
1187 URxvt.keysym.M-C-4: command:\033[8;48;110t
1188
1189=item builtin:
1190
1191The builtin action is the action that @@RXVT_NAME@@ would execute if no
1192key binding existed for the key combination. The obvious use is to undo
1193the effect of existing bindings. The not so obvious use is to reinstate
1194bindings when another binding overrides too many modifiers.
1195
1073if you overwrite the C<Insert> key you will disable @@RXVT_NAME@@'s 1196For 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 1197@@RXVT_NAME@@'s C<Shift-Insert> mapping. To re-enable that, you can poke
1075user-defined keymap using the C<builtin:> replacement: 1198"holes" into the user-defined keymap using the C<builtin:> replacement:
1076 1199

1080The first line defines a mapping for C<Insert> and I<any> combination 1203The first line defines a mapping for C<Insert> and I<any> combination
1081of modifiers. The second line re-establishes the default mapping for 1204of modifiers. The second line re-establishes the default mapping for
1082C<Shift-Insert>. 1205C<Shift-Insert>.
1083 1206
1084The following example will map Control-Meta-1 and Control-Meta-2 to 1207=item builtin-string:
1085the fonts C<suxuseuro> and C<9x15bold>, so you can have some limited
1086font-switching at runtime:
1087 1208
1088 URxvt.keysym.M-C-1: command:\033]50;suxuseuro\007 1209This action is mainly useful to restore string mappings for keys that
1089 URxvt.keysym.M-C-2: command:\033]50;9x15bold\007 1210have predefined actions in @@RXVT_NAME@@. The exact semantics are a bit
1211difficult to explain - basically, this action will send the string to the
1212application that would be sent if @@RXVT_NAME@@ wouldn't have a built-in
1213action for it.
1090 1214
1091Other things are possible, e.g. resizing (see @@RXVT_NAME@@(7) for more 1215An example might make it clearer: @@RXVT_NAME@@ normally pastes the
1092info): 1216selection when you press C<Shift-Insert>. With the following bindings, it
1217would instead emit the (undocumented, but what applications running in the
1218terminal might expect) sequence C<ESC [ 2 $> instead:
1093 1219
1094 URxvt.keysym.M-C-3: command:\033[8;25;80t 1220 URxvt.keysym.S-Insert: builtin-string:
1095 URxvt.keysym.M-C-4: command:\033[8;48;110t 1221 URxvt.keysym.C-S-Insert: builtin:
1222
1223The first line disables the paste functionality for that key
1224combination, and the second reinstates the default behaviour for
1225C<Control-Shift-Insert>, which would otherwise be overridden.
1226
1227Similarly, to let applications gain access to the C<C-M-c> (copy to
1228clipboard) and C<C-M-v> (paste clipboard) key combination, you can do
1229this:
1230
1231 URxvt.keysym.C-M-c: builtin-string:

1570=head2 ALPHA CHANNEL SUPPORT
1571
1572If Xft support has been compiled in and as long as Xft/Xrender/X don't get
1573their act together, rxvt-unicode will do its own alpha channel management:
1574
1575You can prefix any colour with an opaqueness percentage enclosed in
1576brackets, i.e. C<[percent]>, where C<percent> is a decimal percentage
1577(0-100) that specifies the opacity of the colour, where C<0> is completely
1578transparent and C<100> is completely opaque. For example, C<[50]red> is a
1579half-transparent red, while C<[95]#00ff00> is an almost opaque green. This
1580is the recommended format to specify transparency values, and works with
1581all ways to specify a colour.
1582
1583For complete control, rxvt-unicode also supports
1584C<rgba:rrrr/gggg/bbbb/aaaa> (exactly four hex digits/component) colour
1585specifications, where the additional C<aaaa> component specifies opacity
1586(alpha) values. The minimum value of C<0000> is completely transparent,
1587while C<ffff> is completely opaque). The two example colours from
1588earlier could also be specified as C<rgba:ff00/0000/0000/8000> and
1589C<rgba:0000/ff00/0000/f332>.
1590
1591You probably need to specify B<"-depth 32">, too, to force a visual with
1592alpha channels, and have the luck that your X-server uses ARGB pixel
1593layout, as X is far from just supporting ARGB visuals out of the box, and
1594rxvt-unicode just fudges around.
1595
1596For example, the following selects an almost completely transparent black
1597background, and an almost opaque pink foreground:
1598
1599 @@RXVT_NAME@@ -depth 32 -bg rgba:0000/0000/0000/4444 -fg "[80]pink"
1600
1601When not using a background image, then the interpretation of the
1602alpha channel is up to your compositing manager (most interpret it as
1603transparency of course).
1604
1605When using a background pixmap or pseudo-transparency, then the background
1606colour will always behave as if it were completely transparent (so the
1607background image shows instead), regardless of how it was specified, while
1608other colours will either be transparent as specified (the background
1609image will show through) on servers supporting the RENDER extension, or
1610fully opaque on servers not supporting the RENDER EXTENSION.
1611
1612Please note that due to bugs in Xft, specifying alpha values might result
1613in garbage being displayed when the X-server does not support the RENDER
1614extension.
