		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

		1150

		1156	The spellings of I<key> can be obtained by using B<xev>(1) command or
		1157	searching keysym macros from B</usr/X11R6/include/X11/keysymdef.h> and

		1160	performed in an exact manner; however, the closest match is assured.
		1161
		1162	I<string> may contain escape values (C<\n>: newline, C<\000>: octal
		1163	number), see RESOURCES in C<man 7 X> for further details.
		1164
		1165	You can define a range of keysyms in one shot by providing a I<string>
		1166	with pattern B<list/PREFIX/MIDDLE/SUFFIX>, where the delimiter `/'
		1167	should be a character not used by the strings.
		1168
		1169	Its usage can be demonstrated by an example:
		1170
		1171	URxvt.keysym.M-C-0x61: list|\033<|abc|>
		1172
		1173	The above line is equivalent to the following three lines:
		1174
		1175	URxvt.keysym.Meta-Control-0x61: \033<a>
		1176	URxvt.keysym.Meta-Control-0x62: \033<b>
		1177	URxvt.keysym.Meta-Control-0x63: \033<c>
		1178
		1179	If I<string> takes the form of C<command:STRING>, the specified B<STRING>
		1180	is interpreted and executed as @@RXVT_NAME@@'s control sequence. For
		1181	example the following means "change the current locale to C<zh_CN.GBK>
		1182	when Control-Meta-c is being pressed":
		1183
		1184	URxvt.keysym.M-C-c: command:\033]701;zh_CN.GBK\007
		1185
		1186	If I<string> takes the form C<perl:STRING>, then the specified B<STRING>
		1187	is passed to the C<on_user_command> perl handler. See the @@RXVT_NAME@@perl(3)
		1188	manpage. For example, the F<selection> extension (activated via
		1189	C<@@RXVT_NAME@@ -pe selection>) listens for C<selection:rot13> events:
		1190
		1191	URxvt.keysym.M-C-c: perl:selection:rot13
		1192
		1193	Due the the large number of modifier combinations, a defined key mapping
		1194	will match if I<at least> the specified identifiers are being set, and
		1195	no other key mappings with those and more bits are being defined. That
		1196	means that defining a key map for C<a> will automatically provide
		1197	definitions for C<Meta-a>, C<Shift-a> and so on, unless some of those are defined
		1198	mappings themselves.
		1199
		1200	Unfortunately, this will override built-in key mappings. For example
		1201	if you overwrite the C<Insert> key you will disable @@RXVT_NAME@@'s
		1202	C<Shift-Insert> mapping. To re-enable that, you can poke "holes" into the
		1203	user-defined keymap using the C<builtin:> replacement:
		1204
		1205	URxvt.keysym.Insert: <my insert key sequence>
		1206	URxvt.keysym.S-Insert: builtin:
		1207
		1208	The first line defines a mapping for C<Insert> and I<any> combination
		1209	of modifiers. The second line re-establishes the default mapping for
		1210	C<Shift-Insert>.
		1211
		1212	The following example will map Control-Meta-1 and Control-Meta-2 to
		1213	the fonts C<suxuseuro> and C<9x15bold>, so you can have some limited
		1214	font-switching at runtime:
		1215
		1216	URxvt.keysym.M-C-1: command:\033]50;suxuseuro\007
		1217	URxvt.keysym.M-C-2: command:\033]50;9x15bold\007
		1218
		1219	Other things are possible, e.g. resizing (see @@RXVT_NAME@@(7) for more
		1220	info):
		1221
		1222	URxvt.keysym.M-C-3: command:\033[8;25;80t

		1233	them. This can be useful to selectively disable some extensions loaded
		1234	by default, or specified via the C<perl-ext-common> resource. For
		1235	example, C<default,-selection> will use all the default extension except
		1236	C<selection>.
		1237
		1238	Extension names can also be followed by an argument in angle brackets
		1239	(e.g. C<< searchable-scrollback<M-s> >>, which binds the hotkey for
		1240	searchable scrollback to Alt/Meta-s). Mentioning the same extension

		1517	=head2 ALPHA CHANNEL SUPPORT
		1518
		1519	If Xft support has been compiled in and as long as Xft/Xrender/X don't get
		1520	their act together, rxvt-unicode will do it's own alpha channel management:
		1521
		1522	You can prefix any colour with an opaqueness percentage enclosed in
		1523	brackets, i.e. C<[percent]>, where C<percent> is a decimal percentage
		1524	(0-100) that specifies the opacity of the colour, where C<0> is completely
		1525	transparent and C<100> is completely opaque. For example, C<[50]red> is a
		1526	half-transparent red, while C<[95]#00ff00> is an almost opaque green. This
		1527	is the recommended format to specify transparency values, and works with
		1528	all ways to specify a colour.
		1529
		1530	For complete control, rxvt-unicode also supports
		1531	C<rgba:rrrr/gggg/bbbb/aaaa> (exactly four hex digits/component) colour
		1532	specifications, where the additional C<aaaa> component specifies opacity
		1533	(alpha) values. The minimum value of C<0000> is completely transparent,
		1534	while C<ffff> is completely opaque). The two example colours from
		1535	earlier could also be specified as C<rgba:ff00/0000/0000/8000> and
		1536	C<rgba:0000/ff00/0000/f332>.
		1537
		1538	You probably need to specify B<"-depth 32">, too, to force a visual with
		1539	alpha channels, and have the luck that your X-server uses ARGB pixel
		1540	layout, as X is far from just supporting ARGB visuals out of the box, and
		1541	rxvt-unicode just fudges around.
		1542
		1543	For example, the following selects an almost completely transparent black
		1544	background, and an almost opaque pink foreground:
		1545
		1546	@@RXVT_NAME@@ -depth 32 -bg rgba:0000/0000/0000/4444 -fg "[80]pink"
		1547
		1548	When not using a background image, then the interpretation of the
		1549	alpha channel is up to your compositing manager (most interpret it as
		1550	transparency of course).
		1551
		1552	When using a background pixmap or pseudo-transparency, then the background
		1553	colour will always behave as if it were completely transparent (so the
		1554	background image shows instead), regardless of how it was specified, while
		1555	other colours will either be transparent as specified (the background
		1556	image will show through) on servers supporting the RENDER extension, or
		1557	fully opaque on servers not supporting the RENDER EXTENSION.
		1558
		1559	Please note that due to bugs in Xft, specifying alpha values might result
		1560	in garbage being displayed when the X-server does not support the RENDER
