		490
		491	Right now, @@RXVT_NAME@@ will first unmap/map the specified window, so it
		492	shouldn't be a top-level window. @@RXVT_NAME@@ will also reconfigure it
		493	quite a bit, so don't expect it to keep some specific state. It's best to
		494	create an extra subwindow for @@RXVT_NAME@@ and leave it alone.
		495
		496	The window will not be destroyed when @@RXVT_NAME@@ exits.
		497
		498	It might be useful to know that @@RXVT_NAME@@ will not close file
		499	descriptors passed to it (except for stdin/out/err, of course), so you
		500	can use file descriptors to communicate with the programs within the
		501	terminal. This works regardless of whether the C<-embed> option was used or
		502	not.
		503
		504	Here is a short Gtk2-perl snippet that illustrates how this option can be
		505	used (a longer example is in F<doc/embed>):
		506
		507	my $rxvt = new Gtk2::Socket;
		508	$rxvt->signal_connect_after (realize => sub {
		509	my $xid = $_[0]->window->get_xid;
		510	system "@@RXVT_NAME@@ -embed $xid &";
		511	});
		512
		513	=item B<-pty-fd> I<file descriptor>
		514
		515	Tells @@RXVT_NAME@@ NOT to execute any commands or create a new pty/tty
		516	pair but instead use the given file descriptor as the tty master. This is
		517	useful if you want to drive @@RXVT_NAME@@ as a generic terminal emulator
		518	without having to run a program within it.
		519
		520	If this switch is given, @@RXVT_NAME@@ will not create any utmp/wtmp
		521	entries and will not tinker with pty/tty permissions - you have to do that
		522	yourself if you want that.
		523
		524	As an extremely special case, specifying C<-1> will completely suppress
		525	pty/tty operations, which is probably only useful in conjunction with some
		526	perl extension that manages the terminal.
		527
		528	Here is a example in perl that illustrates how this option can be used (a
		529	longer example is in F<doc/pty-fd>):
		530
		531	use IO::Pty;
		532	use Fcntl;
		533
		534	my $pty = new IO::Pty;
		535	fcntl $pty, F_SETFD, 0; # clear close-on-exec
		536	system "@@RXVT_NAME@@ -pty-fd " . (fileno $pty) . "&";
		537	close $pty;
		538
		539	# now communicate with rxvt
		540	my $slave = $pty->slave;
		541	while (<$slave>) { print $slave "got <$_>\n" }
		542
		543	Note that, despite what the name might imply, the file descriptor does not
		544	need to be a pty, it can be a bi-directional pipe as well (e.g. a unix
		545	domain or tcp socket). While tty operations cannot be done in this case,
		546	B<@@RXVT_NAME@@> can still be remote controlled with it:
		547
		548	use Socket;
		549	use Fcntl;
		550
		551	socketpair my $URXVT, my $slave, Socket::AF_UNIX, Socket::SOCK_STREAM, Socket::PF_UNSPEC;
		552	fcntl $slave, Fcntl::F_SETFD, 0;
		553	system "exec @@RXVT_NAME@@ -pty-fd " . (fileno $slave) . " &";
		554	close $slave;
		555
		556	syswrite $URXVT, "Type a secret password: ";

		1140
		1141	The key combination that triggers the action, I<sym>, has the following format:
		1142
		1143	(modifiers-)key
		1144
		1145	Where I<modifiers> can be any combination of the following full or
		1146	abbreviated modifier names:
		1147
		1148	=begin table
		1149
		1150	B<ISOLevel3> B<I>
		1151	B<AppKeypad> B<K>
		1152	B<Control> B<C>
		1153	B<NumLock> B<N>

		1158	B<Mod2> B<2>
		1159	B<Mod3> B<3>
		1160	B<Mod4> B<4>
		1161	B<Mod5> B<5>
		1162
		1163	=end table
		1164
		1165	The B<NumLock>, B<Meta> and B<ISOLevel3> modifiers are usually aliased to
		1166	whatever modifier the NumLock key, Meta/Alt keys or ISO Level3 Shift/AltGr
		1167	keys are being mapped. B<AppKeypad> is a synthetic modifier mapped to the
		1168	current application keymap mode state.
		1169
		1170	Due the the large number of modifier combinations, a key mapping will
		1171	match if I<at least> the specified identifiers are being set, and no other
		1172	key mappings with those and more bits are being defined. That means that
		1173	defining a mapping for C<a> will automatically provide definitions for
		1174	C<Meta-a>, C<Shift-a> and so on, unless some of those are defined mappings
		1175	themselves. See the C<builtin:> action, below, for a way to work around
		1176	this when this is a problem.
		1177
		1178	The spelling of I<key> depends on your implementation of X. An easy way to
		1179	find a key name is to use the B<xev>(1) command. You can find a list by
		1180	looking for the C<XK_> macros in the B<X11/keysymdef.h> include file (omit
		1181	the C<XK_> prefix). Alternatively you can specify I<key> by its hex keysym
		1182	value (B<0x0000 - 0xFFFF>).
		1183
		1184	As with any resource value, the I<action> string may contain backslash
		1185	escape sequences (C<\n>: newline, C<\\>: backslash, C<\000>: octal
		1186	number), see RESOURCES in C<man 7 X> for further details.
		1187
		1188	An action starts with an action prefix that selects a certain type
		1189	of action, followed by a colon. An action string without colons is
		1190	interpreted as a literal string to pass to the tty (as if it was
		1191	prefixed with C<string:>).
		1192
		1193	The following action prefixes are known - extensions can provide
		1194	additional prefixes:
		1195
		1196	=over
		1197
		1198	=item string:STRING
		1199
		1200	If the I<action> starts with C<string:> (or otherwise contains no colons),
		1201	then the remaining C<STRING> will be passed to the program running in the
		1202	terminal. For example, you could replace whatever Shift-Tab outputs by the
		1203	string C<echo rm -rf /> followed by a newline:
		1204
		1205	URxvt.keysym.Shift-Tab: string:echo rm -rf /\n
		1206
		1207	This could in theory be used to completely redefine your keymap.
		1208
		1209	In addition, for actions of this type, you can define a range of
		1210	keysyms in one shot by loading the C<keysym-list> perl extension and
		1211	providing an I<action> with pattern B<list/PREFIX/MIDDLE/SUFFIX>, where
		1212	the delimiter `/' should be a character not used by the strings.
		1213
		1214	Its usage can be demonstrated by an example:
		1215
		1216	URxvt.keysym.M-C-0x61: list|\033<|abc|>
		1217
		1218	The above line is equivalent to the following three lines:
		1219
		1220	URxvt.keysym.Meta-Control-0x61: string:\033<a>
		1221	URxvt.keysym.Meta-Control-0x62: string:\033<b>
		1222	URxvt.keysym.Meta-Control-0x63: string:\033<c>
		1223
		1224	=item command:STRING
		1225
		1226	If I<action> takes the form of C<command:STRING>, the specified B<STRING>
		1227	is interpreted and executed as @@RXVT_NAME@@'s control sequence (basically
		1228	the opposite of C<string:> - instead of sending it to the program running
		1229	in the terminal, it will be treated as if it were program output). This is
		1230	most useful to feed command sequences into @@RXVT_NAME@@.
		1231
		1232	For example the following means "change the current locale to C<zh_CN.GBK>
		1233	when Control-Meta-c is being pressed":
		1234
		1235	URxvt.keysym.M-C-c: command:\033]701;zh_CN.GBK\007
		1236
		1237	The following example will map Control-Meta-1 and Control-Meta-2 to
		1238	the fonts C<suxuseuro> and C<9x15bold>, so you can have some limited
		1239	font-switching at runtime:
		1240
		1241	URxvt.keysym.M-C-1: command:\033]50;suxuseuro\007
		1242	URxvt.keysym.M-C-2: command:\033]50;9x15bold\007
		1243
		1244	Other things are possible, e.g. resizing (see @@RXVT_NAME@@(7) for more
		1245	info):
		1246
		1247	URxvt.keysym.M-C-3: command:\033[8;25;80t
		1248	URxvt.keysym.M-C-4: command:\033[8;48;110t
		1249
		1250	=item builtin:
		1251
		1252	The builtin action is the action that @@RXVT_NAME@@ would execute if no
		1253	key binding existed for the key combination. The obvious use is to undo
		1254	the effect of existing bindings. The not so obvious use is to reinstate
		1255	bindings when another binding overrides too many modifiers.
		1256
		1257	For example if you overwrite the C<Insert> key you will disable
		1258	@@RXVT_NAME@@'s C<Shift-Insert> mapping. To re-enable that, you can poke
		1259	"holes" into the user-defined keymap using the C<builtin:> replacement:
		1260
		1261	URxvt.keysym.Insert: <my insert key sequence>
		1262	URxvt.keysym.S-Insert: builtin:
		1263
		1264	The first line defines a mapping for C<Insert> and I<any> combination
		1265	of modifiers. The second line re-establishes the default mapping for
		1266	C<Shift-Insert>.
		1267
		1268	=item builtin-string:
		1269
		1270	This action is mainly useful to restore string mappings for keys that
		1271	have predefined actions in @@RXVT_NAME@@. The exact semantics are a bit
		1272	difficult to explain - basically, this action will send the string to the
		1273	application that would be sent if @@RXVT_NAME@@ wouldn't have a built-in
		1274	action for it.
		1275
		1276	An example might make it clearer: @@RXVT_NAME@@ normally pastes the
		1277	selection when you press C<Shift-Insert>. With the following bindings, it
		1278	would instead emit the (undocumented, but what applications running in the
		1279	terminal might expect) sequence C<ESC [ 2 $> instead:
		1280
		1281	URxvt.keysym.S-Insert: builtin-string:
		1282	URxvt.keysym.C-S-Insert: builtin:
		1283
		1284	The first line disables the paste functionality for that key
		1285	combination, and the second reinstates the default behaviour for
		1286	C<Control-Shift-Insert>, which would otherwise be overridden.
		1287
		1288	Similarly, to let applications gain access to the C<C-M-c> (copy to
		1289	clipboard) and C<C-M-v> (paste clipboard) key combination, you can do
		1290	this:
		1291
		1292	URxvt.keysym.C-M-c: builtin-string:
		1293	URxvt.keysym.C-M-v: builtin-string:
		1294
		1295	=item EXTENSION:STRING
		1296
		1297	An action of this form invokes the action B<STRING>, if any, provided
		1298	by the @@RXVT_NAME@@perl(3) extension B<EXTENSION>. The extension will
		1299	be loaded automatically if necessary.
		1300
		1301	Not all extensions define actions, but popular extensions that do
		1302	include the I<selection> and I<matcher> extensions (documented in their
		1303	own manpages, @@RXVT_NAME@@-selection(1) and @@RXVT_NAME@@-matcher(1),
		1304	respectively).
		1305
		1306	From the silly examples department, this will rot13-"encrypt"
		1307	@@RXVT_NAME@@'s selection when Alt-Control-c is pressed on typical PC
		1308	keyboards:

		1330	all the default extensions except C<selection>.
		1331
		1332	To prohibit autoloading of extensions, you can prefix them with C</>,
		1333	which will make urxvt refuse to automatically load them (this can be
		1334	overridden, however, by specifying the extension name again without a
		1335	prefix, though). This does not prohibit extensions themselves loading
		1336	other extensions. For example, C<default,/background> will keep the

		1640	=head2 ALPHA CHANNEL SUPPORT
		1641
		1642	If Xft support has been compiled in and as long as Xft/Xrender/X don't get
		1643	their act together, rxvt-unicode will do its own alpha channel management:
		1644
		1645	You can prefix any colour with an opaqueness percentage enclosed in
		1646	brackets, i.e. C<[percent]>, where C<percent> is a decimal percentage
		1647	(0-100) that specifies the opacity of the colour, where C<0> is completely
		1648	transparent and C<100> is completely opaque. For example, C<[50]red> is a
		1649	half-transparent red, while C<[95]#00ff00> is an almost opaque green. This
		1650	is the recommended format to specify transparency values, and works with
		1651	all ways to specify a colour.
		1652
		1653	For complete control, rxvt-unicode also supports
		1654	C<rgba:rrrr/gggg/bbbb/aaaa> (exactly four hex digits/component) colour
		1655	specifications, where the additional C<aaaa> component specifies opacity
		1656	(alpha) values. The minimum value of C<0000> is completely transparent,
		1657	while C<ffff> is completely opaque). The two example colours from
		1658	earlier could also be specified as C<rgba:ff00/0000/0000/8000> and
		1659	C<rgba:0000/ff00/0000/f332>.
		1660
		1661	You probably need to specify B<"-depth 32">, too, to force a visual with
		1662	alpha channels, and have the luck that your X-server uses ARGB pixel
		1663	layout, as X is far from just supporting ARGB visuals out of the box, and
		1664	rxvt-unicode just fudges around.
		1665
		1666	For example, the following selects an almost completely transparent black
		1667	background, and an almost opaque pink foreground:
		1668
		1669	@@RXVT_NAME@@ -depth 32 -bg rgba:0000/0000/0000/4444 -fg "[80]pink"
		1670
		1671	When not using a background image, then the interpretation of the
		1672	alpha channel is up to your compositing manager (most interpret it as
		1673	transparency of course).
		1674
		1675	When using a background pixmap or pseudo-transparency, then the background
		1676	colour will always behave as if it were completely transparent (so the
		1677	background image shows instead), regardless of how it was specified, while
		1678	other colours will either be transparent as specified (the background
		1679	image will show through) on servers supporting the RENDER extension, or
		1680	fully opaque on servers not supporting the RENDER EXTENSION.
		1681
		1682	Please note that due to bugs in Xft, specifying alpha values might result
		1683	in garbage being displayed when the X-server does not support the RENDER
		1684	extension.

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.
1067
1068	=item Mouse cut/paste suddenly no longer works.
1069
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.
1088
1089	color0-7 are the low-intensity colors.
1090
1091	color8-15 are the corresponding high-intensity colors.
1092
1093	=item I don't like the screen colors. How do I change them?
1094
1095	You can change the screen colors at run-time using F<~/.Xdefaults>
1096	resources (or as long-options).
1097
1098	Here are values that are supposed to resemble a VGA screen,
1099	including the murky brown that passes for low-intensity yellow:
1100
1101	Rxvt*color0: #000000
1102	Rxvt*color1: #A80000
1103	Rxvt*color2: #00A800
1104	Rxvt*color3: #A8A800
1105	Rxvt*color4: #0000A8
1106	Rxvt*color5: #A800A8
1107	Rxvt*color6: #00A8A8
1108	Rxvt*color7: #A8A8A8
1109
1110	Rxvt*color8: #000054
1111	Rxvt*color9: #FF0054
1112	Rxvt*color10: #00FF54
1113	Rxvt*color11: #FFFF54
1114	Rxvt*color12: #0000FF
1115	Rxvt*color13: #FF00FF
1116	Rxvt*color14: #00FFFF
1117	Rxvt*color15: #FFFFFF
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
1179	use the `keysym' resource to alter the keystrings associated with keysym
1180	0xFF00 - 0xFFFF (function, cursor keys, etc).
1181
1182	Here's an example for a tn3270 session started using `@@RXVT_NAME@@ -name tn3270'
1183

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.
