		498	create an extra subwindow for @@RXVT_NAME@@ and leave it alone.
		499
		500	The window will not be destroyed when @@RXVT_NAME@@ exits.
		501
		502	It might be useful to know that @@RXVT_NAME@@ will not close file
		503	descriptors passed to it (except for stdin/out/err, of course), so you
		504	can use file descriptors to communicate with the programs within the
		505	terminal. This works regardless of whether the C<-embed> option was used or
		506	not.
		507
		508	Here is a short Gtk2-perl snippet that illustrates how this option can be
		509	used (a longer example is in F<doc/embed>):
		510
		511	my $rxvt = new Gtk2::Socket;
		512	$rxvt->signal_connect_after (realize => sub {

		519	Tells @@RXVT_NAME@@ NOT to execute any commands or create a new pty/tty

		521	useful if you want to drive @@RXVT_NAME@@ as a generic terminal emulator
		522	without having to run a program within it.
		523
		524	If this switch is given, @@RXVT_NAME@@ will not create any utmp/wtmp
		525	entries and will not tinker with pty/tty permissions - you have to do that
		526	yourself if you want that.
		527
		528	As an extremely special case, specifying C<-1> will completely suppress
		529	pty/tty operations, which is probably only useful in conjunction with some
		530	perl extension that manages the terminal.
		531
		532	Here is a example in perl that illustrates how this option can be used (a
		533	longer example is in F<doc/pty-fd>):

		535	use IO::Pty;

		537

		1137	B<Shift>, B<Meta>, B<Lock>, B<Mod1>, B<Mod2>, B<Mod3>, B<Mod4>, B<Mod5>,

		1139	B<2>, B<3>, B<4>, B<5>.
		1140
		1141	The B<NumLock>, B<Meta> and B<ISOLevel3> modifiers are usually aliased to
		1142	whatever modifier the NumLock key, Meta/Alt keys or ISO Level3 Shift/AltGr
		1143	keys are being mapped. B<AppKeypad> is a synthetic modifier mapped to the
		1144	current application keymap mode state.
		1145
		1146	The spellings of I<key> can be obtained by using B<xev>(1) command or
		1147	searching keysym macros from B</usr/X11R6/include/X11/keysymdef.h> and
		1148	omitting the prefix B<XK_>. Alternatively you can specify I<key> by its hex
		1149	keysym value (B<0x0000 - 0xFFFF>). Note that the lookup of I<sym>s is not
		1150	performed in an exact manner; however, the closest match is assured.
		1151
		1152	I<string> may contain escape values (C<\n>: newline, C<\000>: octal
		1153	number), see RESOURCES in C<man 7 X> for futher details.
		1154
		1155	You can define a range of keysyms in one shot by providing a I<string>
		1156	with pattern B<list/PREFIX/MIDDLE/SUFFIX>, where the delimiter `/'
		1157	should be a character not used by the strings.
		1158
		1159	Its usage can be demonstrated by an example:
		1160
		1161	URxvt.keysym.M-C-0x61: list|\033<M-C-|abc|>
		1162
		1163	The above line is equivalent to the following three lines:
		1164
		1165	URxvt.keysym.Meta-Control-0x61: \033<M-C-a>
		1166	URxvt.keysym.Meta-Control-0x62: \033<M-C-b>
		1167	URxvt.keysym.Meta-Control-0x63: \033<M-C-c>
		1168
		1169	If I<string> takes the form of C<command:STRING>, the specified B<STRING>
		1170	is interpreted and executed as @@RXVT_NAME@@'s control sequence. For
		1171	example the following means "change the current locale to C<zh_CN.GBK>
		1172	when Control-Meta-c is being pressed":
		1173
		1174	URxvt.keysym.M-C-c: command:\033]701;zh_CN.GBK\007
		1175
		1176	If I<string> takes the form C<perl:STRING>, then the specified B<STRING>
		1177	is passed to the C<on_keyboard_command> perl handler. See the @@RXVT_NAME@@perl(3)
		1178	manpage. For example, the F<selection> extension (activated via
		1179	C<@@RXVT_NAME@@ -pe selection>) listens for C<selection:rot13> events:
		1180
		1181	URxvt.keysym.M-C-c: perl:selection:rot13
		1182
		1183	Due the the large number of modifier combinations, a defined key mapping
		1184	will match if at I<at least> the specified identifiers are being set, and
		1185	no other key mappings with those and more bits are being defined. That
		1186	means that defining a key map for C<a> will automatically provide
		1187	definitions for C<Meta-a>, C<Shift-a> and so on, unless some of those are defined
		1188	mappings themselves.
		1189
		1190	Unfortunately, this will override built-in key mappings. For example
		1191	if you overwrite the C<Insert> key you will disable @@RXVT_NAME@@'s
		1192	C<Shift-Insert> mapping. To re-enable that, you can poke "holes" into the
		1193	user-defined keymap using the C<builtin:> replacement:
		1194
		1195	URxvt.keysym.Insert: <my insert key sequence>
		1196	URxvt.keysym.S-Insert: builtin:
		1197
		1198	The first line defines a mapping for C<Insert> and I<any> combination
		1199	of modifiers. The second line re-establishes the default mapping for
		1200	C<Shift-Insert>.
		1201
		1202	The following example will map Control-Meta-1 and Control-Meta-2 to
		1203	the fonts C<suxuseuro> and C<9x15bold>, so you can have some limited
		1204	font-switching at runtime:
		1205
		1206	URxvt.keysym.M-C-1: command:\033]50;suxuseuro\007
		1207	URxvt.keysym.M-C-2: command:\033]50;9x15bold\007
		1208
		1209	Other things are possible, e.g. resizing (see @@RXVT_NAME@@(7) for more
		1210	info):
		1211
		1212	URxvt.keysym.M-C-3: command:\033[8;25;80t

		1495
		1496	If Xft support has been compiled in and as long as Xft/Xrender/X don't get
		1497	their act together, rxvt-unicode will do it's own alpha channel management:
		1498
		1499	You can prefix any color with an opaquenes percentage enclosed in
		1500	brackets, i.e. C<[percent]>, where C<percent> is a decimal percentage
		1501	(0-100) that specifies the opacity of the color, where C<0> is completely
		1502	transparent and C<100> is completely opaque. For example, C<[50]red> is a
		1503	half-transparent red, while C<[95]#00ff00> is an almost opaque green. This
		1504	is the recommended format to specify transparency values, and works with
		1505	all ways to specify a colour.
		1506
		1507	For complete control, rxvt-unicode also supports
		1508	C<rgba:rrrr/gggg/bbbb/aaaa> (exactly four hex digits/component) colour
		1509	specifications, where the additional C<aaaa> component specifies opacity
		1510	(alpha) values. The minimum value of C<0000> is completely transparent,
		1511	while C<ffff> is completely opaque). The two example colours from
		1512	earlier could also be specified as C<rgba:ff00/0000/0000/8000> and
		1513	C<rgba:0000/ff00/0000/f332>.
		1514
		1515	You probably need to specify B<"-depth 32">, too, to force a visual with
		1516	alpha channels, and have the luck that your X-server uses ARGB pixel
		1517	layout, as X is far from just supporting ARGB visuals out of the box, and
		1518	rxvt-unicode just fudges around.
		1519
		1520	For example, the following selects an almost completely transparent black
		1521	background, and an almost opaque pink foreground:
		1522
		1523	@@RXVT_NAME@@ -depth 32 -bg rgba:0000/0000/0000/4444 -fg "[80]pink"
		1524
		1525	When not using a background image, then the interpretation of the
		1526	alpha channel is up to your compositing manager (most interpret it as
		1527	transparency of course).
		1528
		1529	When using a background pixmap or pseudo-transparency, then the background
		1530	colour will always behave as if it were completely transparent (so the
		1531	background image shows instead), regardless of how it was specified, while
		1532	other colours will either be transparent as specified (the background
		1533	image will show through) on servers supporting the RENDER extension, or
		1534	fully opaque on servers not supporting the RENDER EXTENSION.
		1535
		1536	Please note that due to bugs in Xft, specifying alpha values might result
		1537	in garbage being displayed when the X-server does not support the RENDER
		1538	extension.
