		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>):
		532
		533	use IO::Pty;
		534	use Fcntl;
		535
		536	my $pty = new IO::Pty;

		1143	B<2>, B<3>, B<4>, B<5>.
		1144
		1145	The B<NumLock>, B<Meta> and B<ISOLevel3> modifiers are usually aliased to
		1146	whatever modifier the NumLock key, Meta/Alt keys or ISO Level3 Shift/AltGr
		1147	keys are being mapped. B<AppKeypad> is a synthetic modifier mapped to the

		1149
		1150	The spellings of I<key> can be obtained by using B<xev>(1) command or
		1151	searching keysym macros from B</usr/X11R6/include/X11/keysymdef.h> and
		1152	omitting the prefix B<XK_>. Alternatively you can specify I<key> by its hex
		1153	keysym value (B<0x0000 - 0xFFFF>). Note that the lookup of I<sym>s is not
		1154	performed in an exact manner; however, the closest match is assured.
		1155
		1156	I<string> may contain escape values (C<\n>: newline, C<\000>: octal
		1157	number), see RESOURCES in C<man 7 X> for further details.
		1158
		1159	You can define a range of keysyms in one shot by providing a I<string>
		1160	with pattern B<list/PREFIX/MIDDLE/SUFFIX>, where the delimiter `/'
		1161	should be a character not used by the strings.
		1162
		1163	Its usage can be demonstrated by an example:
		1164
		1165	URxvt.keysym.M-C-0x61: list|\033<M-C-|abc|>
		1166
		1167	The above line is equivalent to the following three lines:
		1168
		1169	URxvt.keysym.Meta-Control-0x61: \033<M-C-a>
		1170	URxvt.keysym.Meta-Control-0x62: \033<M-C-b>
		1171	URxvt.keysym.Meta-Control-0x63: \033<M-C-c>
		1172
		1173	If I<string> takes the form of C<command:STRING>, the specified B<STRING>
		1174	is interpreted and executed as @@RXVT_NAME@@'s control sequence. For
		1175	example the following means "change the current locale to C<zh_CN.GBK>
		1176	when Control-Meta-c is being pressed":
		1177
		1178	URxvt.keysym.M-C-c: command:\033]701;zh_CN.GBK\007
		1179
		1180	If I<string> takes the form C<perl:STRING>, then the specified B<STRING>
		1181	is passed to the C<on_user_command> perl handler. See the @@RXVT_NAME@@perl(3)
		1182	manpage. For example, the F<selection> extension (activated via
		1183	C<@@RXVT_NAME@@ -pe selection>) listens for C<selection:rot13> events:
		1184
		1185	URxvt.keysym.M-C-c: perl:selection:rot13
		1186
		1187	Due the the large number of modifier combinations, a defined key mapping
		1188	will match if I<at least> the specified identifiers are being set, and
		1189	no other key mappings with those and more bits are being defined. That
		1190	means that defining a key map for C<a> will automatically provide
		1191	definitions for C<Meta-a>, C<Shift-a> and so on, unless some of those are defined
		1192	mappings themselves.
		1193
		1194	Unfortunately, this will override built-in key mappings. For example
		1195	if you overwrite the C<Insert> key you will disable @@RXVT_NAME@@'s
		1196	C<Shift-Insert> mapping. To re-enable that, you can poke "holes" into the
		1197	user-defined keymap using the C<builtin:> replacement:
		1198
		1199	URxvt.keysym.Insert: <my insert key sequence>
		1200	URxvt.keysym.S-Insert: builtin:
		1201
		1202	The first line defines a mapping for C<Insert> and I<any> combination
		1203	of modifiers. The second line re-establishes the default mapping for
		1204	C<Shift-Insert>.
		1205
		1206	The following example will map Control-Meta-1 and Control-Meta-2 to
		1207	the fonts C<suxuseuro> and C<9x15bold>, so you can have some limited
		1208	font-switching at runtime:

		1230	C<selection>.
		1231
		1232	Extension names can also be followed by an argument in angle brackets

		1511	=head2 ALPHA CHANNEL SUPPORT
		1512
		1513	If Xft support has been compiled in and as long as Xft/Xrender/X don't get
		1514	their act together, rxvt-unicode will do it's own alpha channel management:
		1515
		1516	You can prefix any colour with an opaqueness percentage enclosed in
		1517	brackets, i.e. C<[percent]>, where C<percent> is a decimal percentage
		1518	(0-100) that specifies the opacity of the colour, where C<0> is completely
		1519	transparent and C<100> is completely opaque. For example, C<[50]red> is a
		1520	half-transparent red, while C<[95]#00ff00> is an almost opaque green. This
		1521	is the recommended format to specify transparency values, and works with
		1522	all ways to specify a colour.
		1523
		1524	For complete control, rxvt-unicode also supports
		1525	C<rgba:rrrr/gggg/bbbb/aaaa> (exactly four hex digits/component) colour
		1526	specifications, where the additional C<aaaa> component specifies opacity
		1527	(alpha) values. The minimum value of C<0000> is completely transparent,
		1528	while C<ffff> is completely opaque). The two example colours from
		1529	earlier could also be specified as C<rgba:ff00/0000/0000/8000> and
		1530	C<rgba:0000/ff00/0000/f332>.
		1531
		1532	You probably need to specify B<"-depth 32">, too, to force a visual with
		1533	alpha channels, and have the luck that your X-server uses ARGB pixel
		1534	layout, as X is far from just supporting ARGB visuals out of the box, and
		1535	rxvt-unicode just fudges around.
		1536
		1537	For example, the following selects an almost completely transparent black
		1538	background, and an almost opaque pink foreground:
		1539
		1540	@@RXVT_NAME@@ -depth 32 -bg rgba:0000/0000/0000/4444 -fg "[80]pink"
		1541
		1542	When not using a background image, then the interpretation of the
		1543	alpha channel is up to your compositing manager (most interpret it as
		1544	transparency of course).
		1545
		1546	When using a background pixmap or pseudo-transparency, then the background
		1547	colour will always behave as if it were completely transparent (so the
		1548	background image shows instead), regardless of how it was specified, while
		1549	other colours will either be transparent as specified (the background
		1550	image will show through) on servers supporting the RENDER extension, or
		1551	fully opaque on servers not supporting the RENDER EXTENSION.
		1552
		1553	Please note that due to bugs in Xft, specifying alpha values might result
		1554	in garbage being displayed when the X-server does not support the RENDER
		1555	extension.
