		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

		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>):
		532
		533	use IO::Pty;
		534	use Fcntl;
		535

		1151	B<2>, B<3>, B<4>, B<5>.
		1152
		1153	The B<NumLock>, B<Meta> and B<ISOLevel3> modifiers are usually aliased to
		1154	whatever modifier the NumLock key, Meta/Alt keys or ISO Level3 Shift/AltGr
		1155	keys are being mapped. B<AppKeypad> is a synthetic modifier mapped to the
		1156	current application keymap mode state.
		1157
		1158	The spellings of I<key> can be obtained by using B<xev>(1) command or
		1159	searching keysym macros from B</usr/X11R6/include/X11/keysymdef.h> and
		1160	omitting the prefix B<XK_>. Alternatively you can specify I<key> by its hex
		1161	keysym value (B<0x0000 - 0xFFFF>). Note that the lookup of I<sym>s is not
		1162	performed in an exact manner; however, the closest match is assured.
		1163
		1164	I<string> may contain escape values (C<\n>: newline, C<\000>: octal
		1165	number), see RESOURCES in C<man 7 X> for further details.
		1166
		1167	If I<string> takes the form of C<command:STRING>, the specified B<STRING>
		1168	is interpreted and executed as @@RXVT_NAME@@'s control sequence. For
		1169	example the following means "change the current locale to C<zh_CN.GBK>
		1170	when Control-Meta-c is being pressed":
		1171
		1172	URxvt.keysym.M-C-c: command:\033]701;zh_CN.GBK\007
		1173
		1174	If I<string> takes the form C<perl:STRING>, then the specified B<STRING>
		1175	is passed to the C<on_user_command> perl handler. See the @@RXVT_NAME@@perl(3)
		1176	manpage. For example, the F<selection> extension (activated via
		1177	C<@@RXVT_NAME@@ -pe selection>) listens for C<selection:rot13> events:
		1178
		1179	URxvt.keysym.M-C-c: perl:selection:rot13
		1180
		1181	Due the the large number of modifier combinations, a defined key mapping
		1182	will match if I<at least> the specified identifiers are being set, and
		1183	no other key mappings with those and more bits are being defined. That
		1184	means that defining a key map for C<a> will automatically provide
		1185	definitions for C<Meta-a>, C<Shift-a> and so on, unless some of those are defined
		1186	mappings themselves.
		1187
		1188	Unfortunately, this will override built-in key mappings. For example
		1189	if you overwrite the C<Insert> key you will disable @@RXVT_NAME@@'s
		1190	C<Shift-Insert> mapping. To re-enable that, you can poke "holes" into the
		1191	user-defined keymap using the C<builtin:> replacement:
		1192
		1193	URxvt.keysym.Insert: <my insert key sequence>
		1194	URxvt.keysym.S-Insert: builtin:
		1195
		1196	The first line defines a mapping for C<Insert> and I<any> combination
		1197	of modifiers. The second line re-establishes the default mapping for
		1198	C<Shift-Insert>.
		1199
		1200	The following example will map Control-Meta-1 and Control-Meta-2 to
		1201	the fonts C<suxuseuro> and C<9x15bold>, so you can have some limited
		1202	font-switching at runtime:

		1505	=head2 ALPHA CHANNEL SUPPORT
		1506
		1507	If Xft support has been compiled in and as long as Xft/Xrender/X don't get
		1508	their act together, rxvt-unicode will do it's own alpha channel management:
		1509
		1510	You can prefix any colour with an opaqueness percentage enclosed in
		1511	brackets, i.e. C<[percent]>, where C<percent> is a decimal percentage
		1512	(0-100) that specifies the opacity of the colour, where C<0> is completely
		1513	transparent and C<100> is completely opaque. For example, C<[50]red> is a
		1514	half-transparent red, while C<[95]#00ff00> is an almost opaque green. This
		1515	is the recommended format to specify transparency values, and works with
		1516	all ways to specify a colour.
		1517
		1518	For complete control, rxvt-unicode also supports
		1519	C<rgba:rrrr/gggg/bbbb/aaaa> (exactly four hex digits/component) colour
		1520	specifications, where the additional C<aaaa> component specifies opacity
		1521	(alpha) values. The minimum value of C<0000> is completely transparent,
		1522	while C<ffff> is completely opaque). The two example colours from
		1523	earlier could also be specified as C<rgba:ff00/0000/0000/8000> and
		1524	C<rgba:0000/ff00/0000/f332>.
		1525
		1526	You probably need to specify B<"-depth 32">, too, to force a visual with
		1527	alpha channels, and have the luck that your X-server uses ARGB pixel
		1528	layout, as X is far from just supporting ARGB visuals out of the box, and
		1529	rxvt-unicode just fudges around.
		1530
		1531	For example, the following selects an almost completely transparent black
		1532	background, and an almost opaque pink foreground:
		1533
		1534	@@RXVT_NAME@@ -depth 32 -bg rgba:0000/0000/0000/4444 -fg "[80]pink"
		1535
		1536	When not using a background image, then the interpretation of the
		1537	alpha channel is up to your compositing manager (most interpret it as
		1538	transparency of course).
		1539
		1540	When using a background pixmap or pseudo-transparency, then the background
		1541	colour will always behave as if it were completely transparent (so the
		1542	background image shows instead), regardless of how it was specified, while
		1543	other colours will either be transparent as specified (the background
		1544	image will show through) on servers supporting the RENDER extension, or
		1545	fully opaque on servers not supporting the RENDER EXTENSION.
		1546
		1547	Please note that due to bugs in Xft, specifying alpha values might result
		1548	in garbage being displayed when the X-server does not support the RENDER
		1549	extension.
