		454
		455	Right now, @@RXVT_NAME@@ will first unmap/map the specified window, so it
		456	shouldn't be a top-level window. @@RXVT_NAME@@ will also reconfigure it
		457	quite a bit, so don't expect it to keep some specific state. It's best to
		458	create an extra subwindow for @@RXVT_NAME@@ and leave it alone.
		459
		460	The window will not be destroyed when @@RXVT_NAME@@ exits.
		461
		462	It might be useful to know that @@RXVT_NAME@@ will not close file
		463	descriptors passed to it (except for stdin/out/err, of course), so you
		464	can use file descriptors to communicate with the programs within the
		465	terminal. This works regardless of whether the C<-embed> option was used or
		466	not.
		467
		468	Here is a short Gtk2-perl snippet that illustrates how this option can be
		469	used (a longer example is in F<doc/embed>):
		470
		471	my $rxvt = new Gtk2::Socket;
		472	$rxvt->signal_connect_after (realize => sub {
		473	my $xid = $_[0]->window->get_xid;

		478
		479	Tells @@RXVT_NAME@@ NOT to execute any commands or create a new pty/tty

		481	useful if you want to drive @@RXVT_NAME@@ as a generic terminal emulator
		482	without having to run a program within it.
		483
		484	If this switch is given, @@RXVT_NAME@@ will not create any utmp/wtmp
		485	entries and will not tinker with pty/tty permissions - you have to do that
		486	yourself if you want that.
		487
		488	As an extremely special case, specifying C<-1> will completely suppress
		489	pty/tty operations, which is probably only useful in conjunction with some
		490	perl extension that manages the terminal.
		491
		492	Here is a example in perl that illustrates how this option can be used (a
		493	longer example is in F<doc/pty-fd>):

		1056
		1057	The key combination that triggers the action, I<sym>, has the following format:
		1058
		1059	(modifiers-)key
		1060
		1061	Where I<modifiers> can be any combination of B<ISOLevel3>, B<AppKeypad>,
		1062	B<Control>, B<NumLock>, B<Shift>, B<Meta>, B<Lock>, B<Mod1>, B<Mod2>,
		1063	B<Mod3>, B<Mod4>, B<Mod5>, and the abbreviated B<I>, B<K>, B<C>, B<N>,
		1064	B<S>, B<M>, B<A>, B<L>, B<1>, B<2>, B<3>, B<4>, B<5>.
		1065
		1066	The B<NumLock>, B<Meta> and B<ISOLevel3> modifiers are usually aliased to
		1067	whatever modifier the NumLock key, Meta/Alt keys or ISO Level3 Shift/AltGr
		1068	keys are being mapped. B<AppKeypad> is a synthetic modifier mapped to the
		1069	current application keymap mode state.
		1070
		1071	Due the the large number of modifier combinations, a key mapping will
		1072	match if I<at least> the specified identifiers are being set, and no other
		1073	key mappings with those and more bits are being defined. That means that
		1074	defining a mapping for C<a> will automatically provide definitions for
		1075	C<Meta-a>, C<Shift-a> and so on, unless some of those are defined mappings
		1076	themselves. See the C<builtin:> action, below, for a way to work around
		1077	this when this is a problem.
		1078
		1079	The spelling of I<key> depends on your implementation of X. An easy way to
		1080	find a key name is to use the B<xev>(1) command. You can find a list by
		1081	looking for the C<XK_> macros in the B<X11/keysymdef.h> include file (omit
		1082	the C<XK_> prefix). Alternatively you can specify I<key> by its hex keysym
		1083	value (B<0x0000 - 0xFFFF>).
		1084
		1085	As with any resource value, the I<action> string may contain backslash
		1086	escape sequences (C<\n>: newline, C<\\>: backslash, C<\000>: octal
		1087	number), see RESOURCES in C<man 7 X> for further details.
		1088
		1089	An action starts with an action prefix that selects a certain type
		1090	of action, followed by a colon. An action string without colons is
		1091	interpreted as a literal string to pass to the tty (as if it was
		1092	prefixed with C<string:>).
		1093
		1094	The following action prefixes are known - extensions can provide
		1095	additional prefixes:
		1096
		1097	=over 4
		1098
		1099	=item string:STRING
		1100
		1101	If the I<action> starts with C<string:> (or otherwise contains no colons),
		1102	then the remaining C<STRING> will be passed to the program running in the
		1103	terminal. For example, you could replace whatever Shift-Tab outputs by the
		1104	string C<echo rm -rf /> followed by a newline:
		1105
		1106	URxvt.keysym.Shift-Tab: string:echo rm -rf /\n
		1107
		1108	This could in theory be used to completely redefine your keymap.
		1109
		1110	=item command:STRING
		1111
		1112	If I<action> takes the form of C<command:STRING>, the specified B<STRING>
		1113	is interpreted and executed as @@RXVT_NAME@@'s control sequence (basically
		1114	the opposite of C<string:> - instead of sending it to the program running
		1115	in the terminal, it will be treated as if it were program output). This is
		1116	most useful to feed command sequences into @@RXVT_NAME@@.
		1117
		1118	For example the following means "change the current locale to C<zh_CN.GBK>
		1119	when Control-Meta-c is being pressed":
		1120
		1121	URxvt.keysym.M-C-c: command:\033]701;zh_CN.GBK\007
		1122
		1123	The following example will map Control-Meta-1 and Control-Meta-2 to
		1124	the fonts C<suxuseuro> and C<9x15bold>, so you can have some limited
		1125	font-switching at runtime:
		1126
		1127	URxvt.keysym.M-C-1: command:\033]50;suxuseuro\007
		1128	URxvt.keysym.M-C-2: command:\033]50;9x15bold\007
		1129
		1130	Other things are possible, e.g. resizing (see @@RXVT_NAME@@(7) for more
		1131	info):
		1132
		1133	URxvt.keysym.M-C-3: command:\033[8;25;80t
		1134	URxvt.keysym.M-C-4: command:\033[8;48;110t
		1135
		1136	=item builtin:
		1137
		1138	The builtin action is the action that @@RXVT_NAME@@ would execute if no
		1139	key binding existed for the key combination. The obvious use is to undo
		1140	the effect of existing bindings. The not so obvious use is to reinstate
		1141	bindings when another binding overrides too many modifiers.
		1142
		1143	For example if you overwrite the C<Insert> key you will disable
		1144	@@RXVT_NAME@@'s C<Shift-Insert> mapping. To re-enable that, you can poke
		1145	"holes" into the user-defined keymap using the C<builtin:> replacement:
		1146
		1147	URxvt.keysym.Insert: <my insert key sequence>
		1148	URxvt.keysym.S-Insert: builtin:
		1149
		1150	The first line defines a mapping for C<Insert> and I<any> combination
		1151	of modifiers. The second line re-establishes the default mapping for
		1152	C<Shift-Insert>.
		1153
		1154	=item builtin-string:
		1155
		1156	This action is mainly useful to restore string mappings for keys that
		1157	have predefined actions in @@RXVT_NAME@@. The exact semantics are a bit
		1158	difficult to explain - basically, this action will send the string to the
		1159	application that would be sent if @@RXVT_NAME@@ wouldn't have a built-in
		1160	action for it.
		1161
		1162	An example might make it clearer: @@RXVT_NAME@@ normally pastes the
		1163	selection when you press C<Shift-Insert>. With the following bindings, it
		1164	would instead emit the (undocumented, but what applications running in the
		1165	terminal might expect) sequence C<ESC [ 2 $> instead:
		1166
		1167	URxvt.keysym.S-Insert: builtin-string:
		1168	URxvt.keysym.C-S-Insert: builtin:
		1169
		1170	The first line disables the paste functionality for that key
		1171	combination, and the second reinstates the default behaviour for
		1172	C<Control-Shift-Insert>, which would otherwise be overridden.
		1173
		1174	Similarly, to let applications gain access to the C<C-M-c> (copy to
		1175	clipboard) and C<C-M-v> (paste clipboard) key combination, you can do
		1176	this:
		1177
		1178	URxvt.keysym.C-S-c: builtin-string:
		1179	URxvt.keysym.C-S-v: builtin-string:
		1180
		1181	=item EXTENSION:STRING

		1593	values for the 256 colour mode in parentheses).
		1594
		1595	The RGB cube uses indices 16..79 (16..231) using the following formulas:
		1596
		1597	index_88 = (r * 4 + g) * 4 + b + 16 # r, g, b = 0..3
		1598	index_256 = (r * 6 + g) * 6 + b + 16 # r, g, b = 0..5
		1599
		1600	The grayscale ramp uses indices 80..87 (232..239), from 10% to 90% in 10%
		1601	steps (1/26 to 25/26 in 1/26 steps) - black and white are already part of

		1619	White.
		1620
		1621	=head2 ALPHA CHANNEL SUPPORT
		1622
		1623	If Xft support has been compiled in and as long as Xft/Xrender/X don't get
		1624	their act together, rxvt-unicode will do its own alpha channel management:
		1625
		1626	You can prefix any colour with an opaqueness percentage enclosed in
		1627	brackets, i.e. C<[percent]>, where C<percent> is a decimal percentage
		1628	(0-100) that specifies the opacity of the colour, where C<0> is completely
		1629	transparent and C<100> is completely opaque. For example, C<[50]red> is a
		1630	half-transparent red, while C<[95]#00ff00> is an almost opaque green. This
		1631	is the recommended format to specify transparency values, and works with
		1632	all ways to specify a colour.
		1633
		1634	For complete control, rxvt-unicode also supports
		1635	C<rgba:rrrr/gggg/bbbb/aaaa> (exactly four hex digits/component) colour
		1636	specifications, where the additional C<aaaa> component specifies opacity
		1637	(alpha) values. The minimum value of C<0000> is completely transparent,
		1638	while C<ffff> is completely opaque). The two example colours from
		1639	earlier could also be specified as C<rgba:ff00/0000/0000/8000> and
		1640	C<rgba:0000/ff00/0000/f332>.
		1641
		1642	You probably need to specify B<"-depth 32">, too, to force a visual with
		1643	alpha channels, and have the luck that your X-server uses ARGB pixel
		1644	layout, as X is far from just supporting ARGB visuals out of the box, and
		1645	rxvt-unicode just fudges around.
		1646
		1647	For example, the following selects an almost completely transparent black
		1648	background, and an almost opaque pink foreground:
		1649
		1650	@@RXVT_NAME@@ -depth 32 -bg rgba:0000/0000/0000/4444 -fg "[80]pink"
		1651
		1652	When not using a background image, then the interpretation of the
		1653	alpha channel is up to your compositing manager (most interpret it as
		1654	transparency of course).
		1655
		1656	When using a background pixmap or pseudo-transparency, then the background
		1657	colour will always behave as if it were completely transparent (so the
		1658	background image shows instead), regardless of how it was specified, while
		1659	other colours will either be transparent as specified (the background
		1660	image will show through) on servers supporting the RENDER extension, or
		1661	fully opaque on servers not supporting the RENDER EXTENSION.
		1662
		1663	Please note that due to bugs in Xft, specifying alpha values might result
		1664	in garbage being displayed when the X-server does not support the RENDER
		1665	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.

1070	Make sure that mouse reporting is actually turned off since killing
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
1073	quick check is to see if cut/paste works when the Alt or Shift keys are
1074	depressed. See @@RXVT_NAME@@(7)
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
1079	standard foreground colour.
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
1086	On ANSI colours, bold/blink attributes are used to set high-intensity
1087	foreground/background colors.

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

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>.
