		27	=head1 RXVT-UNICODE VS. RXVT
		28
		29	Unlike the original rxvt, B<rxvt-unicode> stores all text in Unicode
		30	internally. That means it can store and display most scripts in the
		31	world. Being a terminal emulator, however, some things are very difficult,
		32	especially cursive scripts such as arabic, vertically written scripts
		33	like mongolian or scripts requiring extremely complex combining rules,
		34	like tibetan or devanagari. Don't expect pretty output when using these
		35	scripts. Most other scripts, latin, cyrillic, kanji, thai etc. should work
		36	fine, though. A somewhat difficult case are right-to-left scripts, such
		37	as hebrew: B<rxvt-unicode> adopts the view that bidirectional algorithms
		38	belong in the application, not the terminal emulator (too many things --
		39	such as cursor-movement while editing -- break otherwise), but that might
		40	change.
		41
		42	If you are looking for a terminal that supports more exotic scripts, let
		43	me recommend C<mlterm>, which is a very user friendly, lean and clean
		44	terminal emulator. In fact, the reason rxvt-unicode was born was solely
		45	because the author couldn't get C<mlterm> to use one font for latin1 and
		46	another for japanese.
		47
		48	Therefore another design rationale was the use of multiple fonts to
		49	display characters: The idea of a single unicode font which many other
		50	programs force onto its users never made sense to me: You should be able
		51	to choose any font for any script freely.
		52
		53	Apart from that, rxvt-unicode is also much better internationalised than
		54	its predecessor, supports things such as XFT and ISO 14755 that are handy
		55	in i18n-environments, is faster, and has a lot bugs less than the original
		56	rxvt. This all in addition to dozens of other small improvements.
		57
		58	It is still faithfully following the original rxvt idea of being lean
		59	and nice on resources: for example, you can still configure rxvt-unicode
		60	without most of its features to get a lean binary. It also comes with
		61	a client/daemon pair that lets you open any number of terminal windows
		62	from within a single process, which makes startup time very fast and
		63	drastically reduces memory usage. See @@RXVT_NAME@@d(1) (daemon) and
		64	@@RXVT_NAME@@c(1) (client).
		65
		66	It also makes technical information about escape sequences (which have
		67	been extended) more accessible: see @@RXVT_NAME@@(7) for technical
		68	reference documentation (escape sequences etc.).

		464	Right now, @@RXVT_NAME@@ will first unmap/map the specified window, so it

		467	create an extra subwindow for @@RXVT_NAME@@ and leave it alone.
		468
		469	The window will not be destroyed when @@RXVT_NAME@@ exits.
		470
		471	It might be useful to know that @@RXVT_NAME@@ will not close file
		472	descriptors passed to it (except for stdin/out/err, of course), so you
		473	can use file descriptors to communicate with the programs within the
		474	terminal. This works regardless of whether the C<-embed> option was used or
		475	not.
		476
		477	Here is a short Gtk2-perl snippet that illustrates how this option can be
		478	used (a longer example is in F<doc/embed>):
		479
		480	my $rxvt = new Gtk2::Socket;
		481	$rxvt->signal_connect_after (realize => sub {
		482	my $xid = $_[0]->window->get_xid;

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

		490	useful if you want to drive @@RXVT_NAME@@ as a generic terminal emulator
		491	without having to run a program within it.
		492
		493	If this switch is given, @@RXVT_NAME@@ will not create any utmp/wtmp
		494	entries and will not tinker with pty/tty permissions - you have to do that
		495	yourself if you want that.
		496
		497	As an extremely special case, specifying C<-1> will completely suppress
		498	pty/tty operations, which is probably only useful in conjunction with some
		499	perl extension that manages the terminal.
		500
		501	Here is a example in perl that illustrates how this option can be used (a

		1078	B<S>, B<M>, B<A>, B<L>, B<1>, B<2>, B<3>, B<4>, B<5>.
		1079

		1084
		1085	Due the the large number of modifier combinations, a key mapping will

		1091	this when this is a problem.
		1092
		1093	The spelling of I<key> depends on your implementation of X. An easy way to
		1094	find a key name is to use the B<xev>(1) command. You can find a list by
		1095	looking for the C<XK_> macros in the B<X11/keysymdef.h> include file (omit
		1096	the C<XK_> prefix). Alternatively you can specify I<key> by its hex keysym
		1097	value (B<0x0000 - 0xFFFF>).
		1098
		1099	As with any resource value, the I<action> string may contain backslash

		1101	number), see RESOURCES in C<man 7 X> for further details.
		1102
		1103	An action starts with an action prefix that selects a certain type
		1104	of action, followed by a colon. An action string without colons is
		1105	interpreted as a literal string to pass to the tty (as if it was
		1106	prefixed with C<string:>).
		1107
		1108	The following action prefixes are known - extensions can provide
		1109	additional prefixes:
		1110
		1111	=over 4
		1112
		1113	=item string:STRING
		1114
		1115	If the I<action> starts with C<string:> (or otherwise contains no colons),
		1116	then the remaining C<STRING> will be passed to the program running in the
		1117	terminal. For example, you could replace whatever Shift-Tab outputs by the
		1118	string C<echo rm -rf /> followed by a newline:
		1119
		1120	URxvt.keysym.Shift-Tab: string:echo rm -rf /\n
		1121
		1122	This could in theory be used to completely redefine your keymap.
		1123
		1124	=item command:STRING
		1125
		1126	If I<action> takes the form of C<command:STRING>, the specified B<STRING>
		1127	is interpreted and executed as @@RXVT_NAME@@'s control sequence (basically
		1128	the opposite of C<string:> - instead of sending it to the program running
		1129	in the terminal, it will be treated as if it were program output). This is
		1130	most useful to feed command sequences into @@RXVT_NAME@@.
		1131
		1132	For example the following means "change the current locale to C<zh_CN.GBK>
		1133	when Control-Meta-c is being pressed":
		1134
		1135	URxvt.keysym.M-C-c: command:\033]701;zh_CN.GBK\007
		1136
		1137	The following example will map Control-Meta-1 and Control-Meta-2 to
		1138	the fonts C<suxuseuro> and C<9x15bold>, so you can have some limited
		1139	font-switching at runtime:
		1140
		1141	URxvt.keysym.M-C-1: command:\033]50;suxuseuro\007
		1142	URxvt.keysym.M-C-2: command:\033]50;9x15bold\007
		1143
		1144	Other things are possible, e.g. resizing (see @@RXVT_NAME@@(7) for more
		1145	info):
		1146
		1147	URxvt.keysym.M-C-3: command:\033[8;25;80t
		1148	URxvt.keysym.M-C-4: command:\033[8;48;110t
		1149
		1150	=item builtin:
		1151
		1152	The builtin action is the action that @@RXVT_NAME@@ would execute if no
		1153	key binding existed for the key combination. The obvious use is to undo
		1154	the effect of existing bindings. The not so obvious use is to reinstate
		1155	bindings when another binding overrides too many modifiers.
		1156
		1157	For example if you overwrite the C<Insert> key you will disable
		1158	@@RXVT_NAME@@'s C<Shift-Insert> mapping. To re-enable that, you can poke
		1159	"holes" into the user-defined keymap using the C<builtin:> replacement:
		1160
		1161	URxvt.keysym.Insert: <my insert key sequence>
		1162	URxvt.keysym.S-Insert: builtin:
		1163
		1164	The first line defines a mapping for C<Insert> and I<any> combination
		1165	of modifiers. The second line re-establishes the default mapping for
		1166	C<Shift-Insert>.
		1167
		1168	=item builtin-string:
		1169
		1170	This action is mainly useful to restore string mappings for keys that
		1171	have predefined actions in @@RXVT_NAME@@. The exact semantics are a bit
		1172	difficult to explain - basically, this action will send the string to the
		1173	application that would be sent if @@RXVT_NAME@@ wouldn't have a built-in
		1174	action for it.
		1175
		1176	An example might make it clearer: @@RXVT_NAME@@ normally pastes the
		1177	selection when you press C<Shift-Insert>. With the following bindings, it
		1178	would instead emit the (undocumented, but what applications running in the
		1179	terminal might expect) sequence C<ESC [ 2 $> instead:
		1180
		1181	URxvt.keysym.S-Insert: builtin-string:
		1182	URxvt.keysym.C-S-Insert: builtin:
		1183
		1184	The first line disables the paste functionality for that key
		1185	combination, and the second reinstates the default behaviour for
		1186	C<Control-Shift-Insert>, which would otherwise be overridden.
		1187
		1188	Similarly, to let applications gain access to the C<C-M-c> (copy to
		1189	clipboard) and C<C-M-v> (paste clipboard) key combination, you can do
		1190	this:
		1191
		1192	URxvt.keysym.C-S-c: builtin-string:
		1193	URxvt.keysym.C-S-v: builtin-string:
		1194
		1195	=item EXTENSION:STRING
		1196
		1197	An action of this form passes the B<STRING> to the @@RXVT_NAME@@perl(3)
		1198	extension of the same name. The extension will be loaded automatically if
		1199	necessary.
		1200
		1201	Not all extensions define key actions, but popular extensions that do
		1202	include the I<selection> and I<matcher> extensions (documented in their
		1203	own manpages, @@RXVT_NAME@@-selection(1) and @@RXVT_NAME@@-matcher(1),
		1204	respectively).
		1205
		1206	From the silly examples department, this will rot13-"encrypt"
		1207	@@RXVT_NAME@@'s selection when Alt-Control-c is pressed on typical PC
		1208	keyboards:
		1209
		1210	URxvt.keysym.M-C-c: selection:rot13
		1211
		1212	=item perl:STRING *DEPRECATED*
		1213
		1214	This is a deprecated way of passing key mappings to perl extensions. It is
		1215	still supported, but should not be used anymore.

		1528	Start by pressing C<Control> and C<Shift> together, then releasing
		1529	them. The next special key (cursor keys, home etc.) you enter will not
		1530	invoke its usual function but instead will insert the corresponding
		1531	keycap symbol. The symbol will only be entered when the key has been
		1532	released, otherwise pressing e.g. C<Shift> would enter the symbol for
		1533	C<ISO Level 2 Switch>, although your intention might have been to enter a

		1542
		1543	This method lets you display the unicode character code associated with

		1545
		1546	You enter this mode by holding down C<Control> and C<Shift> together, then
		1547	pressing and holding the left mouse button and moving around. The unicode
		1548	hex code(s) (it might be a combining character) of the character under the
		1549	pointer is displayed until you release C<Control> and C<Shift>.
		1550
		1551	In addition to the hex codes it will display the font used to draw this
		1552	character - due to implementation reasons, characters combined with
		1553	combining characters, line drawing characters and unknown characters will
		1554	always be drawn using the built-in support font.

		1607	values for the 256 colour mode in parentheses).
		1608
		1609	The RGB cube uses indices 16..79 (16..231) using the following formulas:
		1610

		1612	index_256 = (r * 6 + g) * 6 + b + 16 # r, g, b = 0..5
		1613
		1614	The grayscale ramp uses indices 80..87 (232..239), from 10% to 90% in 10%
		1615	steps (1/26 to 25/26 in 1/26 steps) - black and white are already part of
		1616	the RGB cube.
		1617
		1618	Together, all those colours implement the 88 (256) colour xterm
		1619	colours. Only the first 16 can be changed using resources currently, the
		1620	rest can only be changed via command sequences ("escape codes").

		1631
		1632	would yield White on Black, while on I<xterm>(1) it would yield Black on
		1633	White.
		1634
		1635	=head2 ALPHA CHANNEL SUPPORT
		1636
		1637	If Xft support has been compiled in and as long as Xft/Xrender/X don't get
		1638	their act together, rxvt-unicode will do its own alpha channel management:
		1639
		1640	You can prefix any colour with an opaqueness percentage enclosed in
		1641	brackets, i.e. C<[percent]>, where C<percent> is a decimal percentage
		1642	(0-100) that specifies the opacity of the colour, where C<0> is completely
		1643	transparent and C<100> is completely opaque. For example, C<[50]red> is a
		1644	half-transparent red, while C<[95]#00ff00> is an almost opaque green. This
		1645	is the recommended format to specify transparency values, and works with
		1646	all ways to specify a colour.
		1647
		1648	For complete control, rxvt-unicode also supports
		1649	C<rgba:rrrr/gggg/bbbb/aaaa> (exactly four hex digits/component) colour
		1650	specifications, where the additional C<aaaa> component specifies opacity
		1651	(alpha) values. The minimum value of C<0000> is completely transparent,
		1652	while C<ffff> is completely opaque). The two example colours from
		1653	earlier could also be specified as C<rgba:ff00/0000/0000/8000> and
		1654	C<rgba:0000/ff00/0000/f332>.
		1655
		1656	You probably need to specify B<"-depth 32">, too, to force a visual with
		1657	alpha channels, and have the luck that your X-server uses ARGB pixel
		1658	layout, as X is far from just supporting ARGB visuals out of the box, and
		1659	rxvt-unicode just fudges around.
		1660
		1661	For example, the following selects an almost completely transparent black
		1662	background, and an almost opaque pink foreground:
		1663
		1664	@@RXVT_NAME@@ -depth 32 -bg rgba:0000/0000/0000/4444 -fg "[80]pink"
		1665
		1666	When not using a background image, then the interpretation of the
		1667	alpha channel is up to your compositing manager (most interpret it as
		1668	transparency of course).
		1669
		1670	When using a background pixmap or pseudo-transparency, then the background
		1671	colour will always behave as if it were completely transparent (so the
		1672	background image shows instead), regardless of how it was specified, while
		1673	other colours will either be transparent as specified (the background
		1674	image will show through) on servers supporting the RENDER extension, or
		1675	fully opaque on servers not supporting the RENDER EXTENSION.
		1676
		1677	Please note that due to bugs in Xft, specifying alpha values might result
		1678	in garbage being displayed when the X-server does not support the RENDER
		1679	extension.
