		492
		493	Right now, @@RXVT_NAME@@ will first unmap/map the specified window, so it
		494	shouldn't be a top-level window. @@RXVT_NAME@@ will also reconfigure it
		495	quite a bit, so don't expect it to keep some specific state. It's best to
		496	create an extra subwindow for @@RXVT_NAME@@ and leave it alone.
		497
		498	The window will not be destroyed when @@RXVT_NAME@@ exits.
		499
		500	It might be useful to know that @@RXVT_NAME@@ will not close file
		501	descriptors passed to it (except for stdin/out/err, of course), so you
		502	can use file descriptors to communicate with the programs within the
		503	terminal. This works regardless of whether the C<-embed> option was used or
		504	not.
		505
		506	Here is a short Gtk2-perl snippet that illustrates how this option can be
		507	used (a longer example is in F<doc/embed>):
		508
		509	my $rxvt = new Gtk2::Socket;
		510	$rxvt->signal_connect_after (realize => sub {
		511	my $xid = $_[0]->window->get_xid;

		513	});
		514
		515	=item B<-pty-fd> I<file descriptor>
		516
		517	Tells @@RXVT_NAME@@ NOT to execute any commands or create a new pty/tty
		518	pair but instead use the given file descriptor as the tty master. This is
		519	useful if you want to drive @@RXVT_NAME@@ as a generic terminal emulator
		520	without having to run a program within it.
		521
		522	If this switch is given, @@RXVT_NAME@@ will not create any utmp/wtmp
		523	entries and will not tinker with pty/tty permissions - you have to do that
		524	yourself if you want that.
		525
		526	As an extremely special case, specifying C<-1> will completely suppress
		527	pty/tty operations, which is probably only useful in conjunction with some
		528	perl extension that manages the terminal.
		529
		530	Here is a example in perl that illustrates how this option can be used (a
		531	longer example is in F<doc/pty-fd>):

		533	use IO::Pty;
		534	use Fcntl;
		535

		1230	If I<string> takes the form C<perl:STRING>, then the specified B<STRING>
		1231	is passed to the C<on_user_command> perl handler. See the @@RXVT_NAME@@perl(3)
		1232	manpage. For example, the F<selection> extension (activated via
		1233	C<@@RXVT_NAME@@ -pe selection>) listens for C<selection:rot13> events:
		1234
		1235	URxvt.keysym.M-C-c: perl:selection:rot13
		1236
		1237	Due the the large number of modifier combinations, a defined key mapping
		1238	will match if I<at least> the specified identifiers are being set, and
		1239	no other key mappings with those and more bits are being defined. That
		1240	means that defining a key map for C<a> will automatically provide
		1241	definitions for C<Meta-a>, C<Shift-a> and so on, unless some of those are defined
		1242	mappings themselves.
		1243
		1244	Unfortunately, this will override built-in key mappings. For example
		1245	if you overwrite the C<Insert> key you will disable @@RXVT_NAME@@'s
		1246	C<Shift-Insert> mapping. To re-enable that, you can poke "holes" into the
		1247	user-defined keymap using the C<builtin:> replacement:
		1248
		1249	URxvt.keysym.Insert: <my insert key sequence>
		1250	URxvt.keysym.S-Insert: builtin:
		1251
		1252	The first line defines a mapping for C<Insert> and I<any> combination

		1561	=head2 ALPHA CHANNEL SUPPORT
		1562
		1563	If Xft support has been compiled in and as long as Xft/Xrender/X don't get
		1564	their act together, rxvt-unicode will do it's own alpha channel management:
		1565
		1566	You can prefix any colour with an opaqueness percentage enclosed in
		1567	brackets, i.e. C<[percent]>, where C<percent> is a decimal percentage
		1568	(0-100) that specifies the opacity of the colour, where C<0> is completely
		1569	transparent and C<100> is completely opaque. For example, C<[50]red> is a
		1570	half-transparent red, while C<[95]#00ff00> is an almost opaque green. This
		1571	is the recommended format to specify transparency values, and works with
		1572	all ways to specify a colour.
		1573
		1574	For complete control, rxvt-unicode also supports
		1575	C<rgba:rrrr/gggg/bbbb/aaaa> (exactly four hex digits/component) colour
		1576	specifications, where the additional C<aaaa> component specifies opacity
		1577	(alpha) values. The minimum value of C<0000> is completely transparent,
		1578	while C<ffff> is completely opaque). The two example colours from
		1579	earlier could also be specified as C<rgba:ff00/0000/0000/8000> and
		1580	C<rgba:0000/ff00/0000/f332>.
		1581
		1582	You probably need to specify B<"-depth 32">, too, to force a visual with
		1583	alpha channels, and have the luck that your X-server uses ARGB pixel
		1584	layout, as X is far from just supporting ARGB visuals out of the box, and
		1585	rxvt-unicode just fudges around.
		1586
		1587	For example, the following selects an almost completely transparent black
		1588	background, and an almost opaque pink foreground:
		1589
		1590	@@RXVT_NAME@@ -depth 32 -bg rgba:0000/0000/0000/4444 -fg "[80]pink"
		1591
		1592	When not using a background image, then the interpretation of the
		1593	alpha channel is up to your compositing manager (most interpret it as
		1594	transparency of course).
		1595
		1596	When using a background pixmap or pseudo-transparency, then the background
		1597	colour will always behave as if it were completely transparent (so the
		1598	background image shows instead), regardless of how it was specified, while
		1599	other colours will either be transparent as specified (the background
		1600	image will show through) on servers supporting the RENDER extension, or
		1601	fully opaque on servers not supporting the RENDER EXTENSION.
		1602
		1603	Please note that due to bugs in Xft, specifying alpha values might result
		1604	in garbage being displayed when the X-server does not support the RENDER
		1605	extension.
