		480
		481	Tells @@RXVT_NAME@@ to embed its windows into an already-existing window,
		482	which enables applications to easily embed a terminal.
		483
		484	Right now, @@RXVT_NAME@@ will first unmap/map the specified window, so it
		485	shouldn't be a top-level window. @@RXVT_NAME@@ will also reconfigure it
		486	quite a bit, so don't expect it to keep some specific state. It's best to
		487	create an extra subwindow for @@RXVT_NAME@@ and leave it alone.
		488
		489	The window will not be destroyed when @@RXVT_NAME@@ exits.
		490
		491	It might be useful to know that @@RXVT_NAME@@ will not close file
		492	descriptors passed to it (except for stdin/out/err, of course), so you
		493	can use file descriptors to communicate with the programs within the
		494	terminal. This works regardless of whether the C<-embed> option was used or
		495	not.
		496
		497	Here is a short Gtk2-perl snippet that illustrates how this option can be
		498	used (a longer example is in F<doc/embed>):
		499
		500	my $rxvt = new Gtk2::Socket;
		501	$rxvt->signal_connect_after (realize => sub {
		502	my $xid = $_[0]->window->get_xid;
		503	system "@@RXVT_NAME@@ -embed $xid &";
		504	});
		505
		506	=item B<-pty-fd> I<file descriptor>
		507
		508	Tells @@RXVT_NAME@@ NOT to execute any commands or create a new pty/tty
		509	pair but instead use the given file descriptor as the tty master. This is
		510	useful if you want to drive @@RXVT_NAME@@ as a generic terminal emulator
		511	without having to run a program within it.
		512
		513	If this switch is given, @@RXVT_NAME@@ will not create any utmp/wtmp
		514	entries and will not tinker with pty/tty permissions - you have to do that
		515	yourself if you want that.
		516
		517	As an extremely special case, specifying C<-1> will completely suppress
		518	pty/tty operations, which is probably only useful in conjunction with some
		519	perl extension that manages the terminal.
		520
		521	Here is a example in perl that illustrates how this option can be used (a
		522	longer example is in F<doc/pty-fd>):
		523
		524	use IO::Pty;
		525	use Fcntl;
		526

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

		1232	mappings themselves.
		1233
		1234	Unfortunately, this will override built-in key mappings. For example
		1235	if you overwrite the C<Insert> key you will disable @@RXVT_NAME@@'s
		1236	C<Shift-Insert> mapping. To re-enable that, you can poke "holes" into the
		1237	user-defined keymap using the C<builtin:> replacement:
		1238

		1240	URxvt.keysym.S-Insert: builtin:
		1241

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