		454
		455	Right now, @@RXVT_NAME@@ will first unmap/map the specified window, so it
		456	shouldn't be a top-level window. @@RXVT_NAME@@ will also reconfigure it
		457	quite a bit, so don't expect it to keep some specific state. It's best to
		458	create an extra subwindow for @@RXVT_NAME@@ and leave it alone.
		459
		460	The window will not be destroyed when @@RXVT_NAME@@ exits.
		461
		462	It might be useful to know that @@RXVT_NAME@@ will not close file
		463	descriptors passed to it (except for stdin/out/err, of course), so you
		464	can use file descriptors to communicate with the programs within the
		465	terminal. This works regardless of whether the C<-embed> option was used or
		466	not.
		467
		468	Here is a short Gtk2-perl snippet that illustrates how this option can be
		469	used (a longer example is in F<doc/embed>):
		470
		471	my $rxvt = new Gtk2::Socket;
		472	$rxvt->signal_connect_after (realize => sub {
		473	my $xid = $_[0]->window->get_xid;

		475	});
		476
		477	=item B<-pty-fd> I<file descriptor>
		478
		479	Tells @@RXVT_NAME@@ NOT to execute any commands or create a new pty/tty
		480	pair but instead use the given file descriptor as the tty master. This is
		481	useful if you want to drive @@RXVT_NAME@@ as a generic terminal emulator
		482	without having to run a program within it.
		483
		484	If this switch is given, @@RXVT_NAME@@ will not create any utmp/wtmp
		485	entries and will not tinker with pty/tty permissions - you have to do that
		486	yourself if you want that.
		487
		488	As an extremely special case, specifying C<-1> will completely suppress
		489	pty/tty operations, which is probably only useful in conjunction with some
		490	perl extension that manages the terminal.
		491
		492	Here is a example in perl that illustrates how this option can be used (a
		493	longer example is in F<doc/pty-fd>):

		495	use IO::Pty;
		496	use Fcntl;
		497

		1055	B<2>, B<3>, B<4>, B<5>.
		1056
		1057	The B<NumLock>, B<Meta> and B<ISOLevel3> modifiers are usually aliased to
		1058	whatever modifier the NumLock key, Meta/Alt keys or ISO Level3 Shift/AltGr
		1059	keys are being mapped. B<AppKeypad> is a synthetic modifier mapped to the
		1060	current application keymap mode state.
		1061
		1062	The spellings of I<key> can be obtained by using B<xev>(1) command or
		1063	searching keysym macros from B</usr/X11R6/include/X11/keysymdef.h> and
		1064	omitting the prefix B<XK_>. Alternatively you can specify I<key> by its hex
		1065	keysym value (B<0x0000 - 0xFFFF>). Note that the lookup of I<sym>s is not
		1066	performed in an exact manner; however, the closest match is assured.
		1067
		1068	I<string> may contain escape values (C<\n>: newline, C<\000>: octal
		1069	number), see RESOURCES in C<man 7 X> for further details.
		1070
		1071	You can define a range of keysyms in one shot by
		1072	loading the C<keysym-list> perl extension and providing a I<string>
		1073	with pattern B<list/PREFIX/MIDDLE/SUFFIX>, where the delimiter `/'
		1074	should be a character not used by the strings.
		1075
		1076	Its usage can be demonstrated by an example:
		1077
		1078	URxvt.keysym.M-C-0x61: list|\033<|abc|>
		1079
		1080	The above line is equivalent to the following three lines:
		1081
		1082	URxvt.keysym.Meta-Control-0x61: \033<a>
		1083	URxvt.keysym.Meta-Control-0x62: \033<b>
		1084	URxvt.keysym.Meta-Control-0x63: \033<c>
		1085
		1086	If I<string> takes the form of C<command:STRING>, the specified B<STRING>
		1087	is interpreted and executed as @@RXVT_NAME@@'s control sequence. For
		1088	example the following means "change the current locale to C<zh_CN.GBK>
		1089	when Control-Meta-c is being pressed":
		1090
		1091	URxvt.keysym.M-C-c: command:\033]701;zh_CN.GBK\007
		1092
		1093	If I<string> takes the form C<perl:STRING>, then the specified B<STRING>
		1094	is passed to the C<on_user_command> perl handler. See the @@RXVT_NAME@@perl(3)
		1095	manpage. For example, the F<selection> extension (activated via
		1096	C<@@RXVT_NAME@@ -pe selection>) listens for C<selection:rot13> events:
		1097
		1098	URxvt.keysym.M-C-c: perl:selection:rot13
		1099
		1100	Due the the large number of modifier combinations, a defined key mapping
		1101	will match if I<at least> the specified identifiers are being set, and
		1102	no other key mappings with those and more bits are being defined. That
		1103	means that defining a key map for C<a> will automatically provide
		1104	definitions for C<Meta-a>, C<Shift-a> and so on, unless some of those are defined
		1105	mappings themselves.
		1106
		1107	Unfortunately, this will override built-in key mappings. For example
		1108	if you overwrite the C<Insert> key you will disable @@RXVT_NAME@@'s
		1109	C<Shift-Insert> mapping. To re-enable that, you can poke "holes" into the
		1110	user-defined keymap using the C<builtin:> replacement:
		1111
		1112	URxvt.keysym.Insert: <my insert key sequence>
		1113	URxvt.keysym.S-Insert: builtin:
		1114
		1115	The first line defines a mapping for C<Insert> and I<any> combination
		1116	of modifiers. The second line re-establishes the default mapping for
		1117	C<Shift-Insert>.
		1118
		1119	The following example will map Control-Meta-1 and Control-Meta-2 to
		1120	the fonts C<suxuseuro> and C<9x15bold>, so you can have some limited
		1121	font-switching at runtime:
		1122
		1123	URxvt.keysym.M-C-1: command:\033]50;suxuseuro\007
		1124	URxvt.keysym.M-C-2: command:\033]50;9x15bold\007
		1125
		1126	Other things are possible, e.g. resizing (see @@RXVT_NAME@@(7) for more
		1127	info):
		1128
		1129	URxvt.keysym.M-C-3: command:\033[8;25;80t

		1140	them. This can be useful to selectively disable some extensions loaded
		1141	by default, or specified via the C<perl-ext-common> resource. For
		1142	example, C<default,-selection> will use all the default extension except
		1143	C<selection>.
		1144
		1145	Extension names can also be followed by an argument in angle brackets
		1146	(e.g. C<< searchable-scrollback<M-s> >>, which binds the hotkey for
		1147	searchable scrollback to Alt/Meta-s). Mentioning the same extension

		1544	=head2 ALPHA CHANNEL SUPPORT
		1545
		1546	If Xft support has been compiled in and as long as Xft/Xrender/X don't get
		1547	their act together, rxvt-unicode will do its own alpha channel management:
		1548
		1549	You can prefix any colour with an opaqueness percentage enclosed in
		1550	brackets, i.e. C<[percent]>, where C<percent> is a decimal percentage
		1551	(0-100) that specifies the opacity of the colour, where C<0> is completely
		1552	transparent and C<100> is completely opaque. For example, C<[50]red> is a
		1553	half-transparent red, while C<[95]#00ff00> is an almost opaque green. This
		1554	is the recommended format to specify transparency values, and works with
		1555	all ways to specify a colour.
		1556
		1557	For complete control, rxvt-unicode also supports
		1558	C<rgba:rrrr/gggg/bbbb/aaaa> (exactly four hex digits/component) colour
		1559	specifications, where the additional C<aaaa> component specifies opacity
		1560	(alpha) values. The minimum value of C<0000> is completely transparent,
		1561	while C<ffff> is completely opaque). The two example colours from
		1562	earlier could also be specified as C<rgba:ff00/0000/0000/8000> and
		1563	C<rgba:0000/ff00/0000/f332>.
		1564
		1565	You probably need to specify B<"-depth 32">, too, to force a visual with
		1566	alpha channels, and have the luck that your X-server uses ARGB pixel
		1567	layout, as X is far from just supporting ARGB visuals out of the box, and
		1568	rxvt-unicode just fudges around.
		1569
		1570	For example, the following selects an almost completely transparent black
		1571	background, and an almost opaque pink foreground:
		1572
		1573	@@RXVT_NAME@@ -depth 32 -bg rgba:0000/0000/0000/4444 -fg "[80]pink"
		1574
		1575	When not using a background image, then the interpretation of the
		1576	alpha channel is up to your compositing manager (most interpret it as
