1195
1196Extension names can be prefixed with a C<-> sign to prohibit using
1197them. This can be useful to selectively disable some extensions loaded
1198by default, or specified via the C<perl-ext-common> resource. For
1199example, C<default,-selection> will use all the default extension except
1200C<selection>.
1201
1202Extension names can also be followed by an argument in angle brackets
1203(e.g. C<< searchable-scrollback<M-s> >>, which binds the hotkey for
1204searchable scrollback to Alt/Meta-s). Mentioning the same extension
1205multiple times with different arguments will pass multiple arguments to
1206the extension.
1207
1208Each extension is looked up in the library directories, loaded if
1209necessary, and bound to the current terminal instance.

1447In addition to the colours defined above, @@RXVT_NAME@@ offers an
1448additional 72 colours. The first 64 of those (with indices 16 to 79)
1449consist of a 4*4*4 RGB colour cube (i.e. I<index = r * 16 + g * 4 + b +
145016>), followed by 8 additional shades of gray (with indices 80 to 87).
1451
1452Together, all those colours implement the 88 colour xterm colours. Only
1453the first 16 can be changed using resources currently, the rest can only
1454be changed via command sequences ("escape codes").

1470=head2 ALPHA CHANNEL SUPPORT
1471
1472If Xft support has been compiled in and as long as Xft/Xrender/X don't get
1473their act together, rxvt-unicode will do it's own alpha channel management:
1474
1475You can prefix any color with an opaquenes percentage enclosed in
1476brackets, i.e. C<[percent]>, where C<percent> is a decimal percentage
1477(0-100) that specifies the opacity of the color, where C<0> is completely
1478transparent and C<100> is completely opaque. For example, C<[50]red> is a
1479half-transparent red, while C<[95]#00ff00> is an almost opaque green. This
1480is the recommended format to specify transparency values, and works with
1481all ways to specify a colour.
1482
1483For complete control, rxvt-unicode also supports
1484C<rgba:rrrr/gggg/bbbb/aaaa> (exactly four hex digits/component) colour
1485specifications, where the additional C<aaaa> component specifies opacity
1486(alpha) values. The minimum value of C<0000> is completely transparent,
1487while C<ffff> is completely opaque). The two example colours from
1488earlier could also be specified as C<rgba:ff00/0000/0000/8000> and
1489C<rgba:0000/ff00/0000/f332>.
1490
1491You probably need to specify B<"-depth 32">, too, to force a visual with
1492alpha channels, and have the luck that your X-server uses ARGB pixel
1493layout, as X is far from just supporting ARGB visuals out of the box, and
1494rxvt-unicode just fudges around.
1495
1496For example, the following selects an almost completely transparent black
1497background, and an almost opaque pink foreground:
1498
1499 @@RXVT_NAME@@ -depth 32 -bg rgba:0000/0000/0000/4444 -fg "[80]pink"
1500
1501When not using a background image, then the interpretation of the
1502alpha channel is up to your compositing manager (most interpret it as
1503transparency of course).
1504
1505When using a background pixmap or pseudo-transparency, then the background
1506colour will always behave as if it were completely transparent (so the
1507background image shows instead), regardless of how it was specified, while
1508other colours will either be transparent as specified (the background
1509image will show through) on servers supporting the RENDER extension, or
1510fully opaque on servers not supporting the RENDER EXTENSION.
1511
1512Please note that due to bugs in Xft, specifying alpha values might result
1513in garbage being displayed when the X-server does not support the RENDER
1514extension.
