		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.).

		485	create an extra subwindow for @@RXVT_NAME@@ and leave it alone.
		486
		487	The window will not be destroyed when @@RXVT_NAME@@ exits.
		488
		489	It might be useful to know that @@RXVT_NAME@@ will not close file

		491	can use file descriptors to communicate with the programs within the
		492	terminal. This works regardless of whether the C<-embed> option was used or

		494
		495	Here is a short Gtk2-perl snippet that illustrates how this option can be

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

		509	without having to run a program within it.
		510
		511	If this switch is given, @@RXVT_NAME@@ will not create any utmp/wtmp
		512	entries and will not tinker with pty/tty permissions - you have to do that
		513	yourself if you want that.
		514
		515	As an extremely special case, specifying C<-1> will completely suppress
		516	pty/tty operations, which is probably only useful in conjunction with some

		518
		519	Here is a example in perl that illustrates how this option can be used (a

		1113	B<2>, B<3>, B<4>, B<5>.
		1114

		1116	whatever modifier the NumLock key, Meta/Alt keys or ISO Level3 Shift/AltGr
		1117	keys are being mapped. B<AppKeypad> is a synthetic modifier mapped to the
		1118	current application keymap mode state.
		1119
		1120	The spellings of I<key> can be obtained by using B<xev>(1) command or
		1121	searching keysym macros from B</usr/X11R6/include/X11/keysymdef.h> and
		1122	omitting the prefix B<XK_>. Alternatively you can specify I<key> by its hex
		1123	keysym value (B<0x0000 - 0xFFFF>). Note that the lookup of I<sym>s is not
		1124	performed in an exact manner; however, the closest match is assured.
		1125
		1126	I<string> may contain escape values (C<\n>: newline, C<\000>: octal
		1127	number), see RESOURCES in C<man 7 X> for futher details.
		1128
		1129	You can define a range of keysyms in one shot by providing a I<string>
		1130	with pattern B<list/PREFIX/MIDDLE/SUFFIX>, where the delimiter `/'
		1131	should be a character not used by the strings.
		1132
		1133	Its usage can be demonstrated by an example:
		1134
		1135	URxvt.keysym.M-C-0x61: list|\033<M-C-|abc|>
		1136
		1137	The above line is equivalent to the following three lines:
		1138
		1139	URxvt.keysym.Meta-Control-0x61: \033<M-C-a>
		1140	URxvt.keysym.Meta-Control-0x62: \033<M-C-b>
		1141	URxvt.keysym.Meta-Control-0x63: \033<M-C-c>
		1142
		1143	If I<string> takes the form of C<command:STRING>, the specified B<STRING>
		1144	is interpreted and executed as @@RXVT_NAME@@'s control sequence. For
		1145	example the following means "change the current locale to C<zh_CN.GBK>
		1146	when Control-Meta-c is being pressed":
		1147
		1148	URxvt.keysym.M-C-c: command:\033]701;zh_CN.GBK\007
		1149
		1150	If I<string> takes the form C<perl:STRING>, then the specified B<STRING>
		1151	is passed to the C<on_keyboard_command> perl handler. See the @@RXVT_NAME@@perl(3)
		1152	manpage. For example, the F<selection> extension (activated via
		1153	C<@@RXVT_NAME@@ -pe selection>) listens for C<selection:rot13> events:
		1154
		1155	URxvt.keysym.M-C-c: perl:selection:rot13
		1156
		1157	Due the the large number of modifier combinations, a defined key mapping
		1158	will match if at I<at least> the specified identifiers are being set, and
		1159	no other key mappings with those and more bits are being defined. That
		1160	means that defining a key map for C<a> will automatically provide
		1161	definitions for C<Meta-a>, C<Shift-a> and so on, unless some of those are defined
		1162	mappings themselves.
		1163
		1164	Unfortunately, this will override built-in key mappings. For example
		1165	if you overwrite the C<Insert> key you will disable @@RXVT_NAME@@'s
		1166	C<Shift-Insert> mapping. To re-enable that, you can poke "holes" into the
		1167	user-defined keymap using the C<builtin:> replacement:
		1168
		1169	URxvt.keysym.Insert: <my insert key sequence>
		1170	URxvt.keysym.S-Insert: builtin:
		1171
		1172	The first line defines a mapping for C<Insert> and I<any> combination

		1471
		1472	If Xft support has been compiled in and as long as Xft/Xrender/X don't get
		1473	their act together, rxvt-unicode will do it's own alpha channel management:
		1474
		1475	You can prefix any color with an opaquenes percentage enclosed in
		1476	brackets, i.e. C<[percent]>, where C<percent> is a decimal percentage
		1477	(0-100) that specifies the opacity of the color, where C<0> is completely
		1478	transparent and C<100> is completely opaque. For example, C<[50]red> is a
		1479	half-transparent red, while C<[95]#00ff00> is an almost opaque green. This
		1480	is the recommended format to specify transparency values, and works with
		1481	all ways to specify a colour.
		1482
		1483	For complete control, rxvt-unicode also supports
		1484	C<rgba:rrrr/gggg/bbbb/aaaa> (exactly four hex digits/component) colour
		1485	specifications, where the additional C<aaaa> component specifies opacity
		1486	(alpha) values. The minimum value of C<0000> is completely transparent,
		1487	while C<ffff> is completely opaque). The two example colours from
		1488	earlier could also be specified as C<rgba:ff00/0000/0000/8000> and
		1489	C<rgba:0000/ff00/0000/f332>.
		1490
		1491	You probably need to specify B<"-depth 32">, too, to force a visual with
		1492	alpha channels, and have the luck that your X-server uses ARGB pixel
		1493	layout, as X is far from just supporting ARGB visuals out of the box, and
		1494	rxvt-unicode just fudges around.
		1495
		1496	For example, the following selects an almost completely transparent black
		1497	background, and an almost opaque pink foreground:
		1498
		1499	@@RXVT_NAME@@ -depth 32 -bg rgba:0000/0000/0000/4444 -fg "[80]pink"
		1500
		1501	When not using a background image, then the interpretation of the
		1502	alpha channel is up to your compositing manager (most interpret it as
		1503	transparency of course).
		1504
		1505	When using a background pixmap or pseudo-transparency, then the background
		1506	colour will always behave as if it were completely transparent (so the
		1507	background image shows instead), regardless of how it was specified, while
		1508	other colours will either be transparent as specified (the background
		1509	image will show through) on servers supporting the RENDER extension, or
		1510	fully opaque on servers not supporting the RENDER EXTENSION.
		1511
		1512	Please note that due to bugs in Xft, specifying alpha values might result
		1513	in garbage being displayed when the X-server does not support the RENDER
		1514	extension.
