		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;

		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;

		535

		1188	If I<string> takes the form C<perl:STRING>, then the specified B<STRING>
		1189	is passed to the C<on_user_command> perl handler. See the @@RXVT_NAME@@perl(3)
		1190	manpage. For example, the F<selection> extension (activated via
		1191	C<@@RXVT_NAME@@ -pe selection>) listens for C<selection:rot13> events:
		1192
		1193	URxvt.keysym.M-C-c: perl:selection:rot13

		1195	Due the the large number of modifier combinations, a defined key mapping
		1196	will match if I<at least> the specified identifiers are being set, and
		1197	no other key mappings with those and more bits are being defined. That
		1198	means that defining a key map for C<a> will automatically provide
		1199	definitions for C<Meta-a>, C<Shift-a> and so on, unless some of those are defined
		1200	mappings themselves.
		1201
		1202	Unfortunately, this will override built-in key mappings. For example
		1203	if you overwrite the C<Insert> key you will disable @@RXVT_NAME@@'s
		1204	C<Shift-Insert> mapping. To re-enable that, you can poke "holes" into the
		1205	user-defined keymap using the C<builtin:> replacement:
		1206
		1207	URxvt.keysym.Insert: <my insert key sequence>
		1208	URxvt.keysym.S-Insert: builtin:
		1209
		1210	The first line defines a mapping for C<Insert> and I<any> combination

		1519	=head2 ALPHA CHANNEL SUPPORT
		1520
		1521	If Xft support has been compiled in and as long as Xft/Xrender/X don't get
		1522	their act together, rxvt-unicode will do it's own alpha channel management:
		1523
		1524	You can prefix any colour with an opaqueness percentage enclosed in
		1525	brackets, i.e. C<[percent]>, where C<percent> is a decimal percentage
		1526	(0-100) that specifies the opacity of the colour, where C<0> is completely
		1527	transparent and C<100> is completely opaque. For example, C<[50]red> is a
		1528	half-transparent red, while C<[95]#00ff00> is an almost opaque green. This
		1529	is the recommended format to specify transparency values, and works with
		1530	all ways to specify a colour.
		1531
		1532	For complete control, rxvt-unicode also supports
		1533	C<rgba:rrrr/gggg/bbbb/aaaa> (exactly four hex digits/component) colour
		1534	specifications, where the additional C<aaaa> component specifies opacity
		1535	(alpha) values. The minimum value of C<0000> is completely transparent,
		1536	while C<ffff> is completely opaque). The two example colours from
		1537	earlier could also be specified as C<rgba:ff00/0000/0000/8000> and
		1538	C<rgba:0000/ff00/0000/f332>.
		1539
		1540	You probably need to specify B<"-depth 32">, too, to force a visual with
		1541	alpha channels, and have the luck that your X-server uses ARGB pixel
		1542	layout, as X is far from just supporting ARGB visuals out of the box, and
		1543	rxvt-unicode just fudges around.
		1544
		1545	For example, the following selects an almost completely transparent black
		1546	background, and an almost opaque pink foreground:
		1547
		1548	@@RXVT_NAME@@ -depth 32 -bg rgba:0000/0000/0000/4444 -fg "[80]pink"
		1549
		1550	When not using a background image, then the interpretation of the
		1551	alpha channel is up to your compositing manager (most interpret it as
		1552	transparency of course).
		1553
		1554	When using a background pixmap or pseudo-transparency, then the background
		1555	colour will always behave as if it were completely transparent (so the
		1556	background image shows instead), regardless of how it was specified, while
		1557	other colours will either be transparent as specified (the background
		1558	image will show through) on servers supporting the RENDER extension, or
		1559	fully opaque on servers not supporting the RENDER EXTENSION.
		1560
		1561	Please note that due to bugs in Xft, specifying alpha values might result
		1562	in garbage being displayed when the X-server does not support the RENDER
		1563	extension.
