508Tells @@RXVT_NAME@@ NOT to execute any commands or create a new pty/tty
509pair but instead use the given file descriptor as the tty master. This is
510useful if you want to drive @@RXVT_NAME@@ as a generic terminal emulator
511without having to run a program within it.
512
513If this switch is given, @@RXVT_NAME@@ will not create any utmp/wtmp
514entries and will not tinker with pty/tty permissions - you have to do that
515yourself if you want that.
516
517As an extremely special case, specifying C<-1> will completely suppress
518pty/tty operations, which is probably only useful in conjunction with some
519perl extension that manages the terminal.

1220If I<string> takes the form C<perl:STRING>, then the specified B<STRING>
1221is passed to the C<on_user_command> perl handler. See the @@RXVT_NAME@@perl(3)
1222manpage. For example, the F<selection> extension (activated via

1226
1227Due the the large number of modifier combinations, a defined key mapping
1228will match if I<at least> the specified identifiers are being set, and
1229no other key mappings with those and more bits are being defined. That
1230means that defining a key map for C<a> will automatically provide
1231definitions for C<Meta-a>, C<Shift-a> and so on, unless some of those are defined
1232mappings themselves.
1233
1234Unfortunately, this will override built-in key mappings. For example
1235if you overwrite the C<Insert> key you will disable @@RXVT_NAME@@'s
1236C<Shift-Insert> mapping. To re-enable that, you can poke "holes" into the
1237user-defined keymap using the C<builtin:> replacement:
1238
1239 URxvt.keysym.Insert: <my insert key sequence>
1240 URxvt.keysym.S-Insert: builtin:
1241
1242The first line defines a mapping for C<Insert> and I<any> combination
1243of modifiers. The second line re-establishes the default mapping for
1244C<Shift-Insert>.

1522The following text gives values for the standard 88 colour mode (and
1523values for the 256 colour mode in parentheses).
1524
1525The RGB cube uses indices 16..79 (16..231) using the following formulas:
1526
1527 index_88 = (r * 4 + g) * 4 + b + 16 # r, g, b = 0..3
1528 index_256 = (r * 16 + g) * 16 + b + 16 # r, g, b = 0..15
1529
1530The grayscale ramp uses indices 80..87 (232..239), from 10% to 90% in 10%
1531steps (1/26 to 25/26 in 1/26 steps) - black and white are already part of
1532the RGB cube.
1533
1534Together, all those colours implement the 88 (256) colour xterm
1535colours. Only the first 16 can be changed using resources currently, the
1536rest can only be changed via command sequences ("escape codes").

1551=head2 ALPHA CHANNEL SUPPORT
1552
1553If Xft support has been compiled in and as long as Xft/Xrender/X don't get
1554their act together, rxvt-unicode will do its own alpha channel management:
1555
1556You can prefix any colour with an opaqueness percentage enclosed in
1557brackets, i.e. C<[percent]>, where C<percent> is a decimal percentage
1558(0-100) that specifies the opacity of the colour, where C<0> is completely
1559transparent and C<100> is completely opaque. For example, C<[50]red> is a
1560half-transparent red, while C<[95]#00ff00> is an almost opaque green. This
1561is the recommended format to specify transparency values, and works with
1562all ways to specify a colour.
1563
1564For complete control, rxvt-unicode also supports
1565C<rgba:rrrr/gggg/bbbb/aaaa> (exactly four hex digits/component) colour
1566specifications, where the additional C<aaaa> component specifies opacity
1567(alpha) values. The minimum value of C<0000> is completely transparent,
1568while C<ffff> is completely opaque). The two example colours from
1569earlier could also be specified as C<rgba:ff00/0000/0000/8000> and
1570C<rgba:0000/ff00/0000/f332>.
1571
1572You probably need to specify B<"-depth 32">, too, to force a visual with
1573alpha channels, and have the luck that your X-server uses ARGB pixel
1574layout, as X is far from just supporting ARGB visuals out of the box, and
1575rxvt-unicode just fudges around.
1576
1577For example, the following selects an almost completely transparent black
1578background, and an almost opaque pink foreground:
1579
1580 @@RXVT_NAME@@ -depth 32 -bg rgba:0000/0000/0000/4444 -fg "[80]pink"
1581
1582When not using a background image, then the interpretation of the
1583alpha channel is up to your compositing manager (most interpret it as
1584transparency of course).
1585
1586When using a background pixmap or pseudo-transparency, then the background
1587colour will always behave as if it were completely transparent (so the
1588background image shows instead), regardless of how it was specified, while
1589other colours will either be transparent as specified (the background
1590image will show through) on servers supporting the RENDER extension, or
1591fully opaque on servers not supporting the RENDER EXTENSION.
1592
1593Please note that due to bugs in Xft, specifying alpha values might result
1594in garbage being displayed when the X-server does not support the RENDER
1595extension.
