		463
		464	Right now, @@RXVT_NAME@@ will first unmap/map the specified window, so it
		465	shouldn't be a top-level window. @@RXVT_NAME@@ will also reconfigure it
		466	quite a bit, so don't expect it to keep some specific state. It's best to
		467	create an extra subwindow for @@RXVT_NAME@@ and leave it alone.
		468
		469	The window will not be destroyed when @@RXVT_NAME@@ exits.
		470
		471	It might be useful to know that @@RXVT_NAME@@ will not close file
		472	descriptors passed to it (except for stdin/out/err, of course), so you
		473	can use file descriptors to communicate with the programs within the
		474	terminal. This works regardless of whether the C<-embed> option was used or
		475	not.
		476
		477	Here is a short Gtk2-perl snippet that illustrates how this option can be
		478	used (a longer example is in F<doc/embed>):
		479
		480	my $rxvt = new Gtk2::Socket;
		481	$rxvt->signal_connect_after (realize => sub {
		482	my $xid = $_[0]->window->get_xid;

		484	});

		486	=item B<-pty-fd> I<file descriptor>
		487
		488	Tells @@RXVT_NAME@@ NOT to execute any commands or create a new pty/tty
		489	pair but instead use the given file descriptor as the tty master. This is
		490	useful if you want to drive @@RXVT_NAME@@ as a generic terminal emulator
		491	without having to run a program within it.
		492
		493	If this switch is given, @@RXVT_NAME@@ will not create any utmp/wtmp
		494	entries and will not tinker with pty/tty permissions - you have to do that
		495	yourself if you want that.
		496
		497	As an extremely special case, specifying C<-1> will completely suppress
		498	pty/tty operations, which is probably only useful in conjunction with some
		499	perl extension that manages the terminal.
		500
		501	Here is a example in perl that illustrates how this option can be used (a

		506

		1166
		1167	The builtin action is the action that @@RXVT_NAME@@ would execute if no
		1168	key binding existed for the key combination. The obvious use is to undo
		1169	the effect of existing bindings. The not so obvious use is to reinstate
		1170	bindings when another binding overrides too many modifiers.
		1171
		1172	For example if you overwrite the C<Insert> key you will disable
		1173	@@RXVT_NAME@@'s C<Shift-Insert> mapping. To re-enable that, you can poke
		1174	"holes" into the user-defined keymap using the C<builtin:> replacement:
		1175
		1176	URxvt.keysym.Insert: <my insert key sequence>
		1177	URxvt.keysym.S-Insert: builtin:

		1179	The first line defines a mapping for C<Insert> and I<any> combination

		1182
		1183	=item builtin-string:
		1184
		1185	This action is mainly useful to restore string mappings for keys that
		1186	have predefined actions in @@RXVT_NAME@@. The exact semantics are a bit
		1187	difficult to explain - basically, this action will send the string to the
		1188	application that would be sent if @@RXVT_NAME@@ wouldn't have a built-in
		1189	action for it.
		1190
		1191	An example might make it clearer: @@RXVT_NAME@@ normally pastes the
		1192	selection when you press C<Shift-Insert>. With the following bindings, it
		1193	would instead emit the (undocumented, but what applications running in the
		1194	terminal might expect) sequence C<ESC [ 2 $> instead:
		1195
		1196	URxvt.keysym.S-Insert: builtin-string:
		1197	URxvt.keysym.C-S-Insert: builtin:
		1198
		1199	The first line disables the paste functionality for that key
		1200	combination, and the second reinstates the default behaviour for
		1201	C<Control-Shift-Insert>, which would otherwise be overridden.
		1202
		1203	Similarly, to let applications gain access to the C<C-M-c> (copy to
		1204	clipboard) and C<C-M-v> (paste clipboard) key combination, you can do
		1205	this:
		1206

		1623	The following text gives values for the standard 88 colour mode (and
		1624	values for the 256 colour mode in parentheses).
		1625
		1626	The RGB cube uses indices 16..79 (16..231) using the following formulas:
		1627
		1628	index_88 = (r * 4 + g) * 4 + b + 16 # r, g, b = 0..3
		1629	index_256 = (r * 6 + g) * 6 + b + 16 # r, g, b = 0..5
		1630
		1631	The grayscale ramp uses indices 80..87 (232..239), from 10% to 90% in 10%
		1632	steps (1/26 to 25/26 in 1/26 steps) - black and white are already part of
		1633	the RGB cube.
		1634
		1635	Together, all those colours implement the 88 (256) colour xterm
		1636	colours. Only the first 16 can be changed using resources currently, the
		1637	rest can only be changed via command sequences ("escape codes").
		1638
		1639	Applications are advised to use terminfo or command sequences to discover
		1640	number and RGB values of all colours (yes, you can query this...).

		1648
		1649	would yield White on Black, while on I<xterm>(1) it would yield Black on
		1650	White.
		1651
		1652	=head2 ALPHA CHANNEL SUPPORT
		1653
		1654	If Xft support has been compiled in and as long as Xft/Xrender/X don't get
		1655	their act together, rxvt-unicode will do its own alpha channel management:
		1656
		1657	You can prefix any colour with an opaqueness percentage enclosed in
		1658	brackets, i.e. C<[percent]>, where C<percent> is a decimal percentage
		1659	(0-100) that specifies the opacity of the colour, where C<0> is completely
		1660	transparent and C<100> is completely opaque. For example, C<[50]red> is a
		1661	half-transparent red, while C<[95]#00ff00> is an almost opaque green. This
		1662	is the recommended format to specify transparency values, and works with
		1663	all ways to specify a colour.
		1664
		1665	For complete control, rxvt-unicode also supports
		1666	C<rgba:rrrr/gggg/bbbb/aaaa> (exactly four hex digits/component) colour
		1667	specifications, where the additional C<aaaa> component specifies opacity
		1668	(alpha) values. The minimum value of C<0000> is completely transparent,
		1669	while C<ffff> is completely opaque). The two example colours from
		1670	earlier could also be specified as C<rgba:ff00/0000/0000/8000> and
		1671	C<rgba:0000/ff00/0000/f332>.
		1672
		1673	You probably need to specify B<"-depth 32">, too, to force a visual with
		1674	alpha channels, and have the luck that your X-server uses ARGB pixel
		1675	layout, as X is far from just supporting ARGB visuals out of the box, and
		1676	rxvt-unicode just fudges around.
		1677
		1678	For example, the following selects an almost completely transparent black
		1679	background, and an almost opaque pink foreground:
		1680
		1681	@@RXVT_NAME@@ -depth 32 -bg rgba:0000/0000/0000/4444 -fg "[80]pink"
		1682
		1683	When not using a background image, then the interpretation of the
		1684	alpha channel is up to your compositing manager (most interpret it as
		1685	transparency of course).
		1686
		1687	When using a background pixmap or pseudo-transparency, then the background
		1688	colour will always behave as if it were completely transparent (so the
		1689	background image shows instead), regardless of how it was specified, while
		1690	other colours will either be transparent as specified (the background
		1691	image will show through) on servers supporting the RENDER extension, or
		1692	fully opaque on servers not supporting the RENDER EXTENSION.
		1693
		1694	Please note that due to bugs in Xft, specifying alpha values might result
		1695	in garbage being displayed when the X-server does not support the RENDER
		1696	extension.
