		459
		460	Right now, @@RXVT_NAME@@ will first unmap/map the specified window, so it
		461	shouldn't be a top-level window. @@RXVT_NAME@@ will also reconfigure it
		462	quite a bit, so don't expect it to keep some specific state. It's best to
		463	create an extra subwindow for @@RXVT_NAME@@ and leave it alone.
		464
		465	The window will not be destroyed when @@RXVT_NAME@@ exits.
		466
		467	It might be useful to know that @@RXVT_NAME@@ will not close file
		468	descriptors passed to it (except for stdin/out/err, of course), so you
		469	can use file descriptors to communicate with the programs within the
		470	terminal. This works regardless of whether the C<-embed> option was used or
		471	not.
		472
		473	Here is a short Gtk2-perl snippet that illustrates how this option can be
		474	used (a longer example is in F<doc/embed>):
		475
		476	my $rxvt = new Gtk2::Socket;
		477	$rxvt->signal_connect_after (realize => sub {
		478	my $xid = $_[0]->window->get_xid;

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

		486	useful if you want to drive @@RXVT_NAME@@ as a generic terminal emulator
		487	without having to run a program within it.
		488
		489	If this switch is given, @@RXVT_NAME@@ will not create any utmp/wtmp
		490	entries and will not tinker with pty/tty permissions - you have to do that
		491	yourself if you want that.
		492
		493	As an extremely special case, specifying C<-1> will completely suppress
		494	pty/tty operations, which is probably only useful in conjunction with some
		495	perl extension that manages the terminal.
		496
		497	Here is a example in perl that illustrates how this option can be used (a

		1061
		1062	The key combination that triggers the action, I<sym>, has the following format:
		1063
		1064	(modifiers-)key
		1065
		1066	Where I<modifiers> can be any combination of B<ISOLevel3>, B<AppKeypad>,
		1067	B<Control>, B<NumLock>, B<Shift>, B<Meta>, B<Lock>, B<Mod1>, B<Mod2>,
		1068	B<Mod3>, B<Mod4>, B<Mod5>, and the abbreviated B<I>, B<K>, B<C>, B<N>,
		1069	B<S>, B<M>, B<A>, B<L>, B<1>, B<2>, B<3>, B<4>, B<5>.
		1070
		1071	The B<NumLock>, B<Meta> and B<ISOLevel3> modifiers are usually aliased to
		1072	whatever modifier the NumLock key, Meta/Alt keys or ISO Level3 Shift/AltGr
		1073	keys are being mapped. B<AppKeypad> is a synthetic modifier mapped to the
		1074	current application keymap mode state.
		1075
		1076	Due the the large number of modifier combinations, a key mapping will
		1077	match if I<at least> the specified identifiers are being set, and no other
		1078	key mappings with those and more bits are being defined. That means that
		1079	defining a mapping for C<a> will automatically provide definitions for
		1080	C<Meta-a>, C<Shift-a> and so on, unless some of those are defined mappings
		1081	themselves. See the C<builtin:> action, below, for a way to work around
		1082	this when this is a problem.
		1083
		1084	The spelling of I<key> depends on your implementation of X. An easy way to
		1085	find a key name is to use the B<xev>(1) command. You can find a list by
		1086	looking for the C<XK_> macros in the B<X11/keysymdef.h> include file (omit
		1087	the C<XK_> prefix). Alternatively you can specify I<key> by its hex keysym
		1088	value (B<0x0000 - 0xFFFF>).
		1089
		1090	As with any resource value, the I<action> string may contain backslash
		1091	escape sequences (C<\n>: newline, C<\\>: backslash, C<\000>: octal
		1092	number), see RESOURCES in C<man 7 X> for further details.
		1093
		1094	An action starts with an action prefix that selects a certain type
		1095	of action, followed by a colon. An action string without colons is
		1096	interpreted as a literal string to pass to the tty (as if it was
		1097	prefixed with C<string:>).
		1098
		1099	The following action prefixes are known - extensions can provide
		1100	additional prefixes:
		1101
		1102	=over 4
		1103
		1104	=item string:STRING
		1105
		1106	If the I<action> starts with C<string:> (or otherwise contains no colons),
		1107	then the remaining C<STRING> will be passed to the program running in the
		1108	terminal. For example, you could replace whatever Shift-Tab outputs by the
		1109	string C<echo rm -rf /> followed by a newline:
		1110
		1111	URxvt.keysym.Shift-Tab: string:echo rm -rf /\n
		1112
		1113	This could in theory be used to completely redefine your keymap.
		1114
		1115	=item command:STRING
		1116
		1117	If I<action> takes the form of C<command:STRING>, the specified B<STRING>
		1118	is interpreted and executed as @@RXVT_NAME@@'s control sequence (basically
		1119	the opposite of C<string:> - instead of sending it to the program running
		1120	in the terminal, it will be treated as if it were program output). This is
		1121	most useful to feed command sequences into @@RXVT_NAME@@.
		1122
		1123	For example the following means "change the current locale to C<zh_CN.GBK>
		1124	when Control-Meta-c is being pressed":
		1125
		1126	URxvt.keysym.M-C-c: command:\033]701;zh_CN.GBK\007
		1127
		1128	The following example will map Control-Meta-1 and Control-Meta-2 to
		1129	the fonts C<suxuseuro> and C<9x15bold>, so you can have some limited
		1130	font-switching at runtime:
		1131
		1132	URxvt.keysym.M-C-1: command:\033]50;suxuseuro\007
		1133	URxvt.keysym.M-C-2: command:\033]50;9x15bold\007
		1134
		1135	Other things are possible, e.g. resizing (see @@RXVT_NAME@@(7) for more
		1136	info):
		1137
		1138	URxvt.keysym.M-C-3: command:\033[8;25;80t
		1139	URxvt.keysym.M-C-4: command:\033[8;48;110t
		1140
		1141	=item builtin:
		1142
		1143	The builtin action is the action that @@RXVT_NAME@@ would execute if no
		1144	key binding existed for the key combination. The obvious use is to undo
		1145	the effect of existing bindings. The not so obvious use is to reinstate
		1146	bindings when another binding overrides too many modifiers.
		1147
		1148	For example if you overwrite the C<Insert> key you will disable
		1149	@@RXVT_NAME@@'s C<Shift-Insert> mapping. To re-enable that, you can poke
		1150	"holes" into the user-defined keymap using the C<builtin:> replacement:
		1151
		1152	URxvt.keysym.Insert: <my insert key sequence>
		1153	URxvt.keysym.S-Insert: builtin:
		1154
		1155	The first line defines a mapping for C<Insert> and I<any> combination
		1156	of modifiers. The second line re-establishes the default mapping for
		1157	C<Shift-Insert>.
		1158
		1159	=item builtin-string:
		1160
		1161	This action is mainly useful to restore string mappings for keys that
		1162	have predefined actions in @@RXVT_NAME@@. The exact semantics are a bit
		1163	difficult to explain - basically, this action will send the string to the
		1164	application that would be sent if @@RXVT_NAME@@ wouldn't have a built-in
		1165	action for it.
		1166
		1167	An example might make it clearer: @@RXVT_NAME@@ normally pastes the
		1168	selection when you press C<Shift-Insert>. With the following bindings, it
		1169	would instead emit the (undocumented, but what applications running in the
		1170	terminal might expect) sequence C<ESC [ 2 $> instead:
		1171
		1172	URxvt.keysym.S-Insert: builtin-string:
		1173	URxvt.keysym.C-S-Insert: builtin:
		1174
		1175	The first line disables the paste functionality for that key
		1176	combination, and the second reinstates the default behaviour for
		1177	C<Control-Shift-Insert>, which would otherwise be overridden.
		1178
		1179	Similarly, to let applications gain access to the C<C-M-c> (copy to
		1180	clipboard) and C<C-M-v> (paste clipboard) key combination, you can do
		1181	this:
		1182
		1183	URxvt.keysym.C-S-c: builtin-string:

		1603	index_256 = (r * 6 + g) * 6 + b + 16 # r, g, b = 0..5

		1624	White.
		1625
		1626	=head2 ALPHA CHANNEL SUPPORT
		1627
		1628	If Xft support has been compiled in and as long as Xft/Xrender/X don't get
		1629	their act together, rxvt-unicode will do its own alpha channel management:
		1630
		1631	You can prefix any colour with an opaqueness percentage enclosed in
		1632	brackets, i.e. C<[percent]>, where C<percent> is a decimal percentage
		1633	(0-100) that specifies the opacity of the colour, where C<0> is completely
		1634	transparent and C<100> is completely opaque. For example, C<[50]red> is a
		1635	half-transparent red, while C<[95]#00ff00> is an almost opaque green. This
		1636	is the recommended format to specify transparency values, and works with
		1637	all ways to specify a colour.
		1638
		1639	For complete control, rxvt-unicode also supports
		1640	C<rgba:rrrr/gggg/bbbb/aaaa> (exactly four hex digits/component) colour
		1641	specifications, where the additional C<aaaa> component specifies opacity
		1642	(alpha) values. The minimum value of C<0000> is completely transparent,
		1643	while C<ffff> is completely opaque). The two example colours from
		1644	earlier could also be specified as C<rgba:ff00/0000/0000/8000> and
		1645	C<rgba:0000/ff00/0000/f332>.
		1646
		1647	You probably need to specify B<"-depth 32">, too, to force a visual with
		1648	alpha channels, and have the luck that your X-server uses ARGB pixel
		1649	layout, as X is far from just supporting ARGB visuals out of the box, and
		1650	rxvt-unicode just fudges around.
		1651
		1652	For example, the following selects an almost completely transparent black
		1653	background, and an almost opaque pink foreground:
		1654
		1655	@@RXVT_NAME@@ -depth 32 -bg rgba:0000/0000/0000/4444 -fg "[80]pink"
		1656
		1657	When not using a background image, then the interpretation of the
		1658	alpha channel is up to your compositing manager (most interpret it as
		1659	transparency of course).
		1660
		1661	When using a background pixmap or pseudo-transparency, then the background
		1662	colour will always behave as if it were completely transparent (so the
		1663	background image shows instead), regardless of how it was specified, while
		1664	other colours will either be transparent as specified (the background
		1665	image will show through) on servers supporting the RENDER extension, or
		1666	fully opaque on servers not supporting the RENDER EXTENSION.
		1667
		1668	Please note that due to bugs in Xft, specifying alpha values might result
		1669	in garbage being displayed when the X-server does not support the RENDER
		1670	extension.

929
930	=item Unicode does not seem to work?
931
932	If you encounter strange problems like typing an accented character but
933	getting two unrelated other characters or similar, or if program output is
934	subtly garbled, then you should check your locale settings.
935
936	Rxvt-unicode must be started with the same C<LC_CTYPE> setting as the
937	programs. Often rxvt-unicode is started in the C<C> locale, while the
938	login script running within the rxvt-unicode window changes the locale to
939	sth. else, e.h. C<en_GB.UTF-8>. Needless to say, this is not going to work.
940
941	The best thing is to fix your startup environment, as you will likely run
942	into other problems. If nothing works you can try this in your .profile.
943
944	printf '\e]701;%s\007' "$LC_CTYPE"
945
946	If this doesn't work, then maybe you use a C<LC_CTYPE> specification not
947	supported on your systems. Some systems have a C<locale> comamnd which
948	displays this. If it displays sth. like:
949
950	locale: Cannot set LC_CTYPE to default locale: ...
951
952	Then the locale you specified is not supported on your system.
953
954	If nothing works and you are sure that everything is set correctly then
955	you will need to remember a little known fact: Some programs just don't
956	support locales :(
957
958	=item Why do the characters look ugly?
959
960	=item How does rxvt-unicode choose fonts?
961
962	Most fonts do not contain the full range of Unicode, which is
963	fine. Chances are that the font you (or the admin/package maintainer of
964	your system/os) have specified does not cover all the characters you want
965	to display.
966
967	B<rxvt-unicode> makes a best-effort try at finding a replacement
968	font. Often the result is fine, but sometimes the chosen font looks
969	bad. In that case, select a font of your taste and add it to the font
970	list, e.g.:
971
972	@@RXVT_NAME@@ -fn basefont,font2,font3...
973
974	When rxvt-unicode sees a character, it will first look at the base
975	font. If the base font does not contain the character, it will go to the
976	next font, and so on.
977
978	The only limitation is that all the fonts must not be larger than the base
979	font, as the base font defines the principial cell size, which must be the
980	same due to the way terminals work.
981
982	=item Why do some chinese characters look so different than others?
983
984	This is because there is a difference between script and language --
985	rxvt-unicode does not know which language the text that is output
986	is, as it only knows the unicode character codes. If rxvt-unicode
987	first sees a japanese character, it might choose a japanese font for
988	it. Subseqzuent japanese characters will take that font. Now, many chinese
989	characters aren't represented in japanese fonts, so when the first
990	non-japanese character comes up, rxvt-unicode will look for a chinese font
991	-- unfortunately at this point, it will still use the japanese font for
992	japanese characters that are also chinese.
993
994	The workaround is easy: just tag a chinese font at the end of your font
995	list (see the previous question). The key is to view the font list as
996	a preference list: If you expect more japanese, list a japanese font
997	first. If you expect more chinese, put a chinese font first.
998
999	In the future it might be possible to switch preferences at runtime (the
1000	internal data structure has no problem with using different fonts for
1001	the same character at the same time, but no interface for this has been
1002	designed yet).
1003
1004	=item How does rxvt-unicode determine the encoding to use?
1005
1006	=item Is there an option to switch encodings?
1007
1008	Unlike some other terminals, rxvt-unicode has no encoding switch, and no
1009	specific "utf-8" mode, such as xterm. In fact, it doesn't even know about
1010	UTF-8 or any other encodings with respect to terminal I/O.
1011
1012	The reasons is that there exists a perfectly fine mechanism for selecting
1013	the encoding, doing I/O and (most important) communicating this to all
1014	applications so everybody agrees on character properties such as width and
1015	code number. This mechanism is the I<locale>.
1016
1017	Rxvt-unicode uses the C<LC_CTYPE> locale category to select encoding. All
1018	programs doing the same (that is, most) will automatically agree in the
1019	interpretation of characters.
1020
1021	Unfortunately, there is no system-independent way to select locales, nor
1022	is there a standard on how locale specifiers will look like.
1023
1024	On most systems, the content of the C<LC_CTYPE> environment variable
1025	contains an arbitrary string which corresponds to an already-installed
1026	locale. Common names for locales are C<en_US.UTF-8>, C<de_DE.ISO-8859-15>,
1027	C<ja_JP.EUC-JP>, i.e. C<language_country.encoding>, but other forms
1028	(i.e. C<de> or C<german>) are also common.
1029
1030	Rxvt-unicode ignores all other locale categories, and except for
1031	the encoding, ignores country or language-specific settings,
1032	i.e. C<de_DE.UTF-8> and C<ja_JP.UTF-8> are the same for rxvt-unicode.
1033
1034	If you want to use a specific encoding you have to make sure you start
1035	rxvt-unicode with the correct C<LC_CTYPE> category.
1036
1037	=item Can I switch locales at runtime?
1038
1039	Yes, using an escape sequence. Try sth. like this, which sets
1040	rxvt-unicode's idea of C<LC_CTYPE>.
1041
1042	printf '\e]701;%s\007' ja_JP.SJIS
1043
1044	See also the previous question.
1045
1046	Sometimes this capability is rather handy when you want to work in one
1047	locale (e.g. C<de_DE.UTF-8>) but some programs don't support UTF-8. For
1048	example, I use this script to start C<xjdic>, which first switches to a
1049	locale supported by xjdic and back later:
1050
1051	printf '\e]701;%s\007' ja_JP.SJIS
1052	xjdic -js
1053	printf '\e]701;%s\007' de_DE.UTF-8
1054
1055	=item Can I switch the fonts at runtime?
1056
1057	Yes, using an escape sequence. Try sth. like this, which has the same
1058	effect as using the C<-fn> switch, and takes effect immediately:
1059
1060	printf '\e]50;%s\007' "9x15bold,xft:Kochi Gothic"
1061
1062	This is useful if you e.g. work primarily with japanese (and prefer a
1063	japanese font), but you have to switch to chinese temporarily, where
1064	japanese fonts would only be in your way.
1065
1066	You can think of this as a kind of manual ISO-2022 switching.

1068	=item Mouse cut/paste suddenly no longer works.

1071	some editors prematurely may leave the mouse in mouse report mode. I've
1072	heard that tcsh may use mouse reporting unless it otherwise specified. A

1075
1076	=item What's with this bold/blink stuff?
1077
1078	If no bold colour is set via C<colorBD:>, bold will invert text using the

1080
1081	For the standard background colour, blinking will actually make the
1082	text blink when compiled with C<--enable-blinking>. with standard
1083	colours. Without C<--enable-blinking>, the blink attribute will be
1084	ignored.
1085

1118
1119	=item What's with the strange Backspace/Delete key behaviour?
1120
1121	Assuming that the physical Backspace key corresponds to the
1122	BackSpace keysym (not likely for Linux ... see the following
1123	question) there are two standard values that can be used for
1124	Backspace: C<^H> and C<^?>.
1125
1126	Historically, either value is correct, but rxvt-unicode adopts the debian
1127	policy of using C<^?> when unsure, because it's the one only only correct
1128	choice :).
1129
1130	Rxvt-unicode tries to inherit the current stty settings and uses the value
1131	of `erase' to guess the value for backspace. If rxvt-unicode wasn't
1132	started from a terminal (say, from a menu or by remote shell), then the
1133	system value of `erase', which corresponds to CERASE in <termios.h>, will
1134	be used (which may not be the same as your stty setting).
1135
1136	For starting a new rxvt-unicode:
1137
1138	# use Backspace = ^H
1139	$ stty erase ^H
1140	$ @@RXVT_NAME@@
1141
1142	# use Backspace = ^?
1143	$ stty erase ^?
1144	$ @@RXVT_NAME@@
1145
1146	Toggle with "ESC[36h" / "ESC[36l" as documented in @@RXVT_NAME@@(7).
1147
1148	For an existing rxvt-unicode:
1149
1150	# use Backspace = ^H
1151	$ stty erase ^H
1152	$ echo -n "^[[36h"
1153
1154	# use Backspace = ^?
1155	$ stty erase ^?
1156	$ echo -n "^[[36l"
1157
1158	This helps satisfy some of the Backspace discrepancies that occur, but
1159	if you use Backspace = C<^H>, make sure that the termcap/terminfo value
1160	properly reflects that.
1161
1162	The Delete key is a another casualty of the ill-defined Backspace problem.
1163	To avoid confusion between the Backspace and Delete keys, the Delete
1164	key has been assigned an escape sequence to match the vt100 for Execute
1165	(ESC[3~) and is in the supplied termcap/terminfo.
1166
1167	Some other Backspace problems:
1168
1169	some editors use termcap/terminfo,
1170	some editors (vim I'm told) expect Backspace = ^H,
1171	GNU Emacs (and Emacs-like editors) use ^H for help.
1172
1173	Perhaps someday this will all be resolved in a consistent manner.
1174
1175	=item I don't like the key-bindings. How do I change them?
1176
1177	There are some compile-time selections available via configure. Unless
1178	you have run "configure" with the C<--disable-resources> option you can

1223	=item I'm using keyboard model XXX that has extra Prior/Next/Insert keys.
1224	How do I make use of them? For example, the Sun Keyboard type 4
1225	has the following mappings that rxvt-unicode doesn't recognize.
1226
1227	KP_Insert == Insert
1228	F22 == Print
1229	F27 == Home
1230	F29 == Prior
1231	F33 == End
1232	F35 == Next
1233
1234	Rather than have rxvt-unicode try to accomodate all the various possible keyboard
1235	mappings, it is better to use `xmodmap' to remap the keys as required for
1236	your particular machine.
1237
1238	=item How do I distinguish if I'm running rxvt-unicode or a regular xterm?
1239	I need this to decide about setting colors etc.
1240
1241	rxvt and rxvt-unicode always export the variable "COLORTERM", so you can
1242	check and see if that is set. Note that several programs, JED, slrn,
1243	Midnight Commander automatically check this variable to decide whether or
1244	not to use color.
1245
1246	=item How do I set the correct, full IP address for the DISPLAY variable?
1247
1248	If you've compiled rxvt-unicode with DISPLAY_IS_IP and ahve enabled
1249	insecure mode then it is possible to use the following shell script
1250	snippets to correctly set the display. If your version of rxvt-unicode
1251	wasn't also compiled with ESCZ_ANSWER (as assumed in these snippets) then
1252	the COLORTERM variable can be used to distinguish rxvt-unicode from a
1253	regular xterm.
1254
1255	Courtesy of Chuck Blake <cblake@BBN.COM> with the following shell script
1256	snippets:
1257
1258	# Bourne/Korn/POSIX family of shells:
1259	[ ${TERM:-foo} = foo ] && TERM=xterm # assume an xterm if we don't know
1260	if [ ${TERM:-foo} = xterm ]; then
1261	stty -icanon -echo min 0 time 15 # see if enhanced rxvt or not
1262	echo -n '^[Z'
1263	read term_id
1264	stty icanon echo
1265	if [ ""${term_id} = '^[[?1;2C' -a ${DISPLAY:-foo} = foo ]; then
1266	echo -n '^[[7n' # query the rxvt we are in for the DISPLAY string
1267	read DISPLAY # set it in our local shell
1268	fi
1269	fi
1270
1271	=item How do I compile the manual pages for myself?
1272
1273	You need to have a recent version of perl installed as F</usr/bin/perl>,
1274	one that comes with F<pod2man>, F<pod2text> and F<pod2html>. Then go to
1275	the doc subdirectory and enter C<make alldoc>.
