1110
1111Extension names can be prefixed with a C<-> sign to prohibit using
1112them. This can be useful to selectively disable some extensions loaded
1113by default, or specified via the C<perl-ext-common> resource. For
1114example, C<default,-selection> will use all the default extension except
1115C<selection>.
1116
1117Extension names can also be followed by an argument in angle brackets
1118(e.g. C<< searchable-scrollback<M-s> >>, which binds the hotkey for
1119searchable scrollback to Alt/Meta-s). Mentioning the same extension
1120multiple times with different arguments will pass multiple arguments to
1121the extension.
1122
1123Each extension is looked up in the library directories, loaded if
1124necessary, and bound to the current terminal instance.
1125
1126If both of these resources are the empty string, then the perl
1127interpreter will not be initialized. The idea behind two options is that
1128B<perl-ext-common> will be used for extensions that should be available to

1383If Xft support has been compiled in and as long as Xft/Xrender/X don't get
1384their act together, rxvt-unicode will support C<rgba:rrrr/gggg/bbbb/aaaa>
1385(recommended, but B<MUST> have 4 digits/component) colour specifications,
1386in addition to the ones provided by X, where the additional A component
1387specifies opacity (alpha) values. The minimum value of C<0> is completely
1388transparent). You can also prefix any color with C<[percent]>, where
1389C<percent> is a decimal percentage (0-100) that specifies the opacity of
1390the color, where C<0> is completely transparent and C<100> is completelxy
1391opaque.

1393You probably need to specify B<"-depth 32">, too, and have the luck that
1394your X-server uses ARGB pixel layout, as X is far from just supporting
1395ARGB visuals out of the box, and rxvt-unicode just fudges around.
