		464
		465	Right now, @@RXVT_NAME@@ will first unmap/map the specified window, so it
		466	shouldn't be a top-level window. @@RXVT_NAME@@ will also reconfigure it
		467	quite a bit, so don't expect it to keep some specific state. It's best to
		468	create an extra subwindow for @@RXVT_NAME@@ and leave it alone.
		469
		470	The window will not be destroyed when @@RXVT_NAME@@ exits.
		471
		472	It might be useful to know that @@RXVT_NAME@@ will not close file
		473	descriptors passed to it (except for stdin/out/err, of course), so you
		474	can use file descriptors to communicate with the programs within the
		475	terminal. This works regardless of whether the C<-embed> option was used or
		476	not.
		477
		478	Here is a short Gtk2-perl snippet that illustrates how this option can be
		479	used (a longer example is in F<doc/embed>):
		480
		481	my $rxvt = new Gtk2::Socket;
		482	$rxvt->signal_connect_after (realize => sub {
		483	my $xid = $_[0]->window->get_xid;

		488
		489	Tells @@RXVT_NAME@@ NOT to execute any commands or create a new pty/tty
		490	pair but instead use the given file descriptor as the tty master. This is
		491	useful if you want to drive @@RXVT_NAME@@ as a generic terminal emulator
		492	without having to run a program within it.
		493
		494	If this switch is given, @@RXVT_NAME@@ will not create any utmp/wtmp
		495	entries and will not tinker with pty/tty permissions - you have to do that
		496	yourself if you want that.
		497
		498	As an extremely special case, specifying C<-1> will completely suppress
		499	pty/tty operations, which is probably only useful in conjunction with some
		500	perl extension that manages the terminal.
		501
		502	Here is a example in perl that illustrates how this option can be used (a

		1071
		1072	The key combination that triggers the action, I<sym>, has the following format:
		1073
		1074	(modifiers-)key
		1075
		1076	Where I<modifiers> can be any combination of B<ISOLevel3>, B<AppKeypad>,
		1077	B<Control>, B<NumLock>, B<Shift>, B<Meta>, B<Lock>, B<Mod1>, B<Mod2>,
		1078	B<Mod3>, B<Mod4>, B<Mod5>, and the abbreviated B<I>, B<K>, B<C>, B<N>,
		1079	B<S>, B<M>, B<A>, B<L>, B<1>, B<2>, B<3>, B<4>, B<5>.
		1080
		1081	The B<NumLock>, B<Meta> and B<ISOLevel3> modifiers are usually aliased to
		1082	whatever modifier the NumLock key, Meta/Alt keys or ISO Level3 Shift/AltGr
		1083	keys are being mapped. B<AppKeypad> is a synthetic modifier mapped to the
		1084	current application keymap mode state.
		1085
		1086	Due the the large number of modifier combinations, a key mapping will
		1087	match if I<at least> the specified identifiers are being set, and no other
		1088	key mappings with those and more bits are being defined. That means that
		1089	defining a mapping for C<a> will automatically provide definitions for
		1090	C<Meta-a>, C<Shift-a> and so on, unless some of those are defined mappings
		1091	themselves. See the C<builtin:> action, below, for a way to work around
		1092	this when this is a problem.
		1093
		1094	The spelling of I<key> depends on your implementation of X. An easy way to
		1095	find a key name is to use the B<xev>(1) command. You can find a list by
		1096	looking for the C<XK_> macros in the B<X11/keysymdef.h> include file (omit
		1097	the C<XK_> prefix). Alternatively you can specify I<key> by its hex keysym
		1098	value (B<0x0000 - 0xFFFF>).
		1099
		1100	As with any resource value, the I<action> string may contain backslash
		1101	escape sequences (C<\n>: newline, C<\\>: backslash, C<\000>: octal
		1102	number), see RESOURCES in C<man 7 X> for further details.
		1103
		1104	An action starts with an action prefix that selects a certain type
		1105	of action, followed by a colon. An action string without colons is
		1106	interpreted as a literal string to pass to the tty (as if it was
		1107	prefixed with C<string:>).
		1108
		1109	The following action prefixes are known - extensions can provide
		1110	additional prefixes:
		1111
		1112	=over 4
		1113
		1114	=item string:STRING
		1115
		1116	If the I<action> starts with C<string:> (or otherwise contains no colons),
		1117	then the remaining C<STRING> will be passed to the program running in the
		1118	terminal. For example, you could replace whatever Shift-Tab outputs by the
		1119	string C<echo rm -rf /> followed by a newline:
		1120
		1121	URxvt.keysym.Shift-Tab: string:echo rm -rf /\n
		1122
		1123	This could in theory be used to completely redefine your keymap.
		1124
		1125	In addition, for actions of this type, you can define a range of
		1126	keysyms in one shot by loading the C<keysym-list> perl extension and
		1127	providing an I<action> with pattern B<list/PREFIX/MIDDLE/SUFFIX>, where
		1128	the delimiter `/' should be a character not used by the strings.
		1129
		1130	Its usage can be demonstrated by an example:
		1131
		1132	URxvt.keysym.M-C-0x61: list|\033<|abc|>
		1133
		1134	The above line is equivalent to the following three lines:
		1135
		1136	URxvt.keysym.Meta-Control-0x61: string:\033<a>
		1137	URxvt.keysym.Meta-Control-0x62: string:\033<b>
		1138	URxvt.keysym.Meta-Control-0x63: string:\033<c>
		1139
		1140	=item command:STRING
		1141
		1142	If I<action> takes the form of C<command:STRING>, the specified B<STRING>
		1143	is interpreted and executed as @@RXVT_NAME@@'s control sequence (basically
		1144	the opposite of C<string:> - instead of sending it to the program running
		1145	in the terminal, it will be treated as if it were program output). This is
		1146	most useful to feed command sequences into @@RXVT_NAME@@.
		1147
		1148	For example the following means "change the current locale to C<zh_CN.GBK>
		1149	when Control-Meta-c is being pressed":
		1150
		1151	URxvt.keysym.M-C-c: command:\033]701;zh_CN.GBK\007
		1152
		1153	The following example will map Control-Meta-1 and Control-Meta-2 to
		1154	the fonts C<suxuseuro> and C<9x15bold>, so you can have some limited
		1155	font-switching at runtime:
		1156
		1157	URxvt.keysym.M-C-1: command:\033]50;suxuseuro\007
		1158	URxvt.keysym.M-C-2: command:\033]50;9x15bold\007
		1159
		1160	Other things are possible, e.g. resizing (see @@RXVT_NAME@@(7) for more
		1161	info):
		1162
		1163	URxvt.keysym.M-C-3: command:\033[8;25;80t

		1166	=item builtin:
		1167
		1168	The builtin action is the action that @@RXVT_NAME@@ would execute if no
		1169	key binding existed for the key combination. The obvious use is to undo
		1170	the effect of existing bindings. The not so obvious use is to reinstate
		1171	bindings when another binding overrides too many modifiers.
		1172
		1173	For example if you overwrite the C<Insert> key you will disable
		1174	@@RXVT_NAME@@'s C<Shift-Insert> mapping. To re-enable that, you can poke
		1175	"holes" into the user-defined keymap using the C<builtin:> replacement:
		1176
		1177	URxvt.keysym.Insert: <my insert key sequence>
		1178	URxvt.keysym.S-Insert: builtin:
		1179
		1180	The first line defines a mapping for C<Insert> and I<any> combination
		1181	of modifiers. The second line re-establishes the default mapping for
		1182	C<Shift-Insert>.
		1183
		1184	=item builtin-string:
		1185
		1186	This action is mainly useful to restore string mappings for keys that
		1187	have predefined actions in @@RXVT_NAME@@. The exact semantics are a bit
		1188	difficult to explain - basically, this action will send the string to the
		1189	application that would be sent if @@RXVT_NAME@@ wouldn't have a built-in
		1190	action for it.
		1191
		1192	An example might make it clearer: @@RXVT_NAME@@ normally pastes the
		1193	selection when you press C<Shift-Insert>. With the following bindings, it
		1194	would instead emit the (undocumented, but what applications running in the
		1195	terminal might expect) sequence C<ESC [ 2 $> instead:
		1196
		1197	URxvt.keysym.S-Insert: builtin-string:
		1198	URxvt.keysym.C-S-Insert: builtin:
		1199
		1200	The first line disables the paste functionality for that key
		1201	combination, and the second reinstates the default behaviour for
		1202	C<Control-Shift-Insert>, which would otherwise be overridden.
		1203
		1204	Similarly, to let applications gain access to the C<C-M-c> (copy to
		1205	clipboard) and C<C-M-v> (paste clipboard) key combination, you can do
		1206	this:
		1207
		1208	URxvt.keysym.C-M-c: builtin-string:
		1209	URxvt.keysym.C-M-v: builtin-string:
		1210
		1211	=item EXTENSION:STRING

		1214	by the @@RXVT_NAME@@perl(3) extension B<EXTENSION>. The extension will
		1215	be loaded automatically if necessary.
		1216

		1244	by default, or specified via the C<perl-ext-common> resource. For
		1245	example, C<default,-selection> will use all the default extensions except

		1260
		1261	If both of these resources are the empty string, then the perl interpreter

		1626
		1627	The RGB cube uses indices 16..79 (16..231) using the following formulas:
		1628
		1629	index_88 = (r * 4 + g) * 4 + b + 16 # r, g, b = 0..3

		1651	White.
		1652
		1653	=head2 ALPHA CHANNEL SUPPORT
		1654
		1655	If Xft support has been compiled in and as long as Xft/Xrender/X don't get
		1656	their act together, rxvt-unicode will do its own alpha channel management:
		1657
		1658	You can prefix any colour with an opaqueness percentage enclosed in
		1659	brackets, i.e. C<[percent]>, where C<percent> is a decimal percentage
		1660	(0-100) that specifies the opacity of the colour, where C<0> is completely
		1661	transparent and C<100> is completely opaque. For example, C<[50]red> is a
		1662	half-transparent red, while C<[95]#00ff00> is an almost opaque green. This
		1663	is the recommended format to specify transparency values, and works with
		1664	all ways to specify a colour.
		1665
		1666	For complete control, rxvt-unicode also supports
		1667	C<rgba:rrrr/gggg/bbbb/aaaa> (exactly four hex digits/component) colour
		1668	specifications, where the additional C<aaaa> component specifies opacity
		1669	(alpha) values. The minimum value of C<0000> is completely transparent,
		1670	while C<ffff> is completely opaque). The two example colours from
		1671	earlier could also be specified as C<rgba:ff00/0000/0000/8000> and
		1672	C<rgba:0000/ff00/0000/f332>.
		1673
		1674	You probably need to specify B<"-depth 32">, too, to force a visual with
		1675	alpha channels, and have the luck that your X-server uses ARGB pixel
		1676	layout, as X is far from just supporting ARGB visuals out of the box, and
		1677	rxvt-unicode just fudges around.
		1678
		1679	For example, the following selects an almost completely transparent black
		1680	background, and an almost opaque pink foreground:
		1681
		1682	@@RXVT_NAME@@ -depth 32 -bg rgba:0000/0000/0000/4444 -fg "[80]pink"
		1683
		1684	When not using a background image, then the interpretation of the
		1685	alpha channel is up to your compositing manager (most interpret it as
		1686	transparency of course).
		1687
		1688	When using a background pixmap or pseudo-transparency, then the background
		1689	colour will always behave as if it were completely transparent (so the
		1690	background image shows instead), regardless of how it was specified, while
		1691	other colours will either be transparent as specified (the background
		1692	image will show through) on servers supporting the RENDER extension, or
		1693	fully opaque on servers not supporting the RENDER EXTENSION.
		1694
		1695	Please note that due to bugs in Xft, specifying alpha values might result
		1696	in garbage being displayed when the X-server does not support the RENDER
		1697	extension.

998
999	The terminal description used by rxvt-unicode is not as widely available
1000	as that for xterm, or even rxvt (for which the same problem often arises).
1001
1002	The correct solution for this problem is to install the terminfo, this can be done
1003	like this:
1004
1005	infocmp rxvt-unicode >rxvt.unicode.tic
1006	scp rxvt-unicode.tic remotesystem:
1007	ssh remotesystem tic rxvt-unicode.tic
1008
1009	... or by installing rxvt-unicode normally on the remote system,
1010
1011	If you cannot or do not want to do this, then you can simply set
1012	C<TERM=rxvt> or even C<TERM=xterm>, and live with the small number of
1013	problems arising, which includes wrong keymapping, less and different
1014	colours and some refresh errors in fullscreen applications. It's a nice
1015	quick-and-dirty workaround for rare cases, though.
1016
1017	If you always want to do this you can either recompile rxvt-unicode with
1018	the desired TERM value or use a resource to set it:
1019
1020	URxvt.termName: rxvt
1021
1022	=item How can I configure rxvt-unicode so that it looks similar to the original rxvt?
1023
1024	Felix von Leitner says that these two lines, in your F<.Xdefaults>, will make rxvt-unicode
1025	behave similar to the original rxvt:
1026
1027	URxvt.font: -misc-fixed-medium-r-semicondensed--13-120-75-75-c-60-iso8859-1
1028	URxvt.boldFont: -misc-fixed-bold-r-semicondensed--13-120-75-75-c-60-iso8859-1
1029
1030	=item Rxvt-unicode does not seem to understand the selected encoding?
1031
1032	=item Unicode does not seem to work?
1033
1034	If you encounter strange problems like typing an accented character but
1035	getting two unrelated other characters or similar, or if program output is
1036	subtly garbled, then you should check your locale settings.
1037
1038	Rxvt-unicode must be started with the same C<LC_CTYPE> setting as the
1039	programs. Often rxvt-unicode is started in the C<C> locale, while the
1040	login script running within the rxvt-unicode window changes the locale to
1041	sth. else, e.h. C<en_GB.UTF-8>. Needless to say, this is not going to work.
1042
1043	The best thing is to fix your startup environment, as you will likely run
1044	into other problems. If nothing works you can try this in your .profile.
1045
1046	printf '\e]701;%s\007' "$LC_CTYPE"
1047
1048	If this doesn't work, then maybe you use a C<LC_CTYPE> specification not
1049	supported on your systems. Some systems have a C<locale> comamnd which
1050	displays this. If it displays sth. like:
1051
1052	locale: Cannot set LC_CTYPE to default locale: ...
1053
1054	Then the locale you specified is not supported on your system.
1055
1056	If nothing works and you are sure that everything is set correctly then
1057	you will need to remember a little known fact: Some programs just don't
1058	support locales :(
1059
1060	=item Why do the characters look ugly?
1061
1062	=item How does rxvt-unicode choose fonts?
1063
1064	Most fonts do not contain the full range of Unicode, which is
1065	fine. Chances are that the font you (or the admin/package maintainer of
1066	your system/os) have specified does not cover all the characters you want
1067	to display.
1068
1069	B<rxvt-unicode> makes a best-effort try at finding a replacement
1070	font. Often the result is fine, but sometimes the chosen font looks
1071	bad. Many fonts have totally strange characters that don't resemble the
1072	correct glyph at all, and rxvt-unicode lacks the artificial intelligence
1073	to detetc that a specific glyph is wrong: it has to believe the font that
1074	the characters it contains indeed look correct.
1075
1076	In that case, select a font of your taste and add it to the font list,
1077	e.g.:
1078
1079	@@RXVT_NAME@@ -fn basefont,font2,font3...
1080
1081	When rxvt-unicode sees a character, it will first look at the base
1082	font. If the base font does not contain the character, it will go to the
1083	next font, and so on. Specifying your own fonts will also speed up this
1084	search and use less resources within rxvt-unicode and the X-server.
1085
1086	The only limitation is that all the fonts must not be larger than the base
1087	font, as the base font defines the principial cell size, which must be the
1088	same due to the way terminals work.
1089
1090	=item Why do some chinese characters look so different than others?
1091
1092	This is because there is a difference between script and language --
1093	rxvt-unicode does not know which language the text that is output
1094	is, as it only knows the unicode character codes. If rxvt-unicode
1095	first sees a japanese character, it might choose a japanese font for
1096	it. Subseqzuent japanese characters will take that font. Now, many chinese
1097	characters aren't represented in japanese fonts, so when the first
1098	non-japanese character comes up, rxvt-unicode will look for a chinese font
1099	-- unfortunately at this point, it will still use the japanese font for
1100	japanese characters that are also chinese.
1101
1102	The workaround is easy: just tag a chinese font at the end of your font
1103	list (see the previous question). The key is to view the font list as
1104	a preference list: If you expect more japanese, list a japanese font
1105	first. If you expect more chinese, put a chinese font first.
1106
1107	In the future it might be possible to switch preferences at runtime (the
1108	internal data structure has no problem with using different fonts for
1109	the same character at the same time, but no interface for this has been
1110	designed yet).
1111
1112	=item How can I keep rxvt-unicode from using reverse video so much?
1113
1114	First of all, make sure you are running with the right terminfo
1115	(C<urxvt>), which will get rid of most of these effects. Then make sure
1116	you have specified colours for italic and bold, as otherwise rxvt-unicode
1117	might use reverse video to simulate the effect:
1118
1119	URxvt*colorBD: white
1120	URxvt*colorIT: green
1121
1122	=item Some programs assume totally weird colours (red instead of blue), how can I fix that?
1123
1124	For some unexplainable reason, some programs (i.e. irssi) assume a very
1125	weird colour palette when confronted with a terminal with more than the
1126	standard 8 colours (rxvt-unicode supports 88). The right fix is, of
1127	course, to fix these programs not to assume non-ISO colours without very
1128	good reasons.
1129
1130	In the meantime, you can either edit your C<urxvt> terminfo definition to
1131	only claim 8 colour support or use C<TERM=rxvt>, which will fix colours
1132	but keep you from using other rxvt-unicode features.
1133
1134	=item How does rxvt-unicode determine the encoding to use?
1135
1136	=item Is there an option to switch encodings?
1137
1138	Unlike some other terminals, rxvt-unicode has no encoding switch, and no
1139	specific "utf-8" mode, such as xterm. In fact, it doesn't even know about
1140	UTF-8 or any other encodings with respect to terminal I/O.
1141
1142	The reasons is that there exists a perfectly fine mechanism for selecting
1143	the encoding, doing I/O and (most important) communicating this to all
1144	applications so everybody agrees on character properties such as width and
1145	code number. This mechanism is the I<locale>.
1146
1147	Rxvt-unicode uses the C<LC_CTYPE> locale category to select encoding. All
1148	programs doing the same (that is, most) will automatically agree in the
1149	interpretation of characters.
1150
1151	Unfortunately, there is no system-independent way to select locales, nor
1152	is there a standard on how locale specifiers will look like.
1153
1154	On most systems, the content of the C<LC_CTYPE> environment variable
1155	contains an arbitrary string which corresponds to an already-installed
1156	locale. Common names for locales are C<en_US.UTF-8>, C<de_DE.ISO-8859-15>,
1157	C<ja_JP.EUC-JP>, i.e. C<language_country.encoding>, but other forms
1158	(i.e. C<de> or C<german>) are also common.
1159
1160	Rxvt-unicode ignores all other locale categories, and except for
1161	the encoding, ignores country or language-specific settings,
1162	i.e. C<de_DE.UTF-8> and C<ja_JP.UTF-8> are the same for rxvt-unicode.
1163
1164	If you want to use a specific encoding you have to make sure you start
1165	rxvt-unicode with the correct C<LC_CTYPE> category.
1166
1167	=item Can I switch locales at runtime?
1168
1169	Yes, using an escape sequence. Try sth. like this, which sets
1170	rxvt-unicode's idea of C<LC_CTYPE>.
1171
1172	printf '\e]701;%s\007' ja_JP.SJIS
1173
1174	See also the previous question.
1175
1176	Sometimes this capability is rather handy when you want to work in one
1177	locale (e.g. C<de_DE.UTF-8>) but some programs don't support UTF-8. For
1178	example, I use this script to start C<xjdic>, which first switches to a
1179	locale supported by xjdic and back later:
1180
1181	printf '\e]701;%s\007' ja_JP.SJIS
1182	xjdic -js
1183	printf '\e]701;%s\007' de_DE.UTF-8
1184
1185	=item Can I switch the fonts at runtime?
1186
1187	Yes, using an escape sequence. Try sth. like this, which has the same
1188	effect as using the C<-fn> switch, and takes effect immediately:
1189
1190	printf '\e]50;%s\007' "9x15bold,xft:Kochi Gothic"
1191
1192	This is useful if you e.g. work primarily with japanese (and prefer a
1193	japanese font), but you have to switch to chinese temporarily, where
1194	japanese fonts would only be in your way.
1195
1196	You can think of this as a kind of manual ISO-2022 switching.
1197
1198	=item Why do italic characters look as if clipped?
1199
1200	Many fonts have difficulties with italic characters and hinting. For
1201	example, the otherwise very nicely hinted font C<xft:Bitstream Vera Sans
1202	Mono> completely fails in it's italic face. A workaround is to enable
1203	freetype autohinting, i.e. like this:

1208	=item My input method wants <some encoding> but I want UTF-8, what can I do?
1209
1210	You cna specify separate locales for the input method and the rest of the
1211	terminal, using the resource C<imlocale>:
1212
1213	URxvt*imlocale: ja_JP.EUC-JP
1214
1215	Now you can start your terminal with C<LC_CTYPE=ja_JP.UTF-8> and still
1216	use your input method. Please note, however, that you will not be able to
1217	input characters outside C<EUC-JP> in a normal way then, as your input
1218	method limits you.
1219
1220	=item Rxvt-unicode uses gobs of memory, how can I reduce that?
1221
1222	Rxvt-unicode tries to obey the rule of not charging you for sth. you
1223	don't use. One thing you should try is to configure out all settings that
1224	you don't need, for example, Xft support is a resource hog by design,
1225	when used. Compiling it out ensures that no Xft font will be loaded
1226	accidentally when rxvt-unicode tries to find a font for your characters.
1227
1228	Also, many people (me included) like large windows and even larger
1229	scrollback buffers: Without C<--enable-unicode3>, rxvt-unicode will use
1230	6 bytes per screen cell. For a 160x?? window this amounts to almost a
1231	kilobyte per line. A scorllback buffer of 10000 lines will then (if full)
1232	use 10 Megabytes of memory. With C<--enable-unicode3> it gets worse, as
1233	rxvt-unicode then uses 8 bytes per screen cell.
1234
1235	=item Can I speed up Xft rendering somehow?
1236
1237	Yes, the most obvious way to speed it up is to avoid Xft entirely, as
1238	it is simply slow. If you still want Xft fonts you might try to disable
1239	antialiasing (by appending C<:antialiasing=false>), which saves lots of
1240	memory and also speeds up rendering considerably.
1241
1242	=item Rxvt-unicode doesn't seem to anti-alias its fonts, what is wrong?
1243
1244	Rxvt-unicode will use whatever you specify as a font. If it needs to
1245	fall back to it's default font search list it will prefer X11 core
1246	fonts, because they are small and fast, and then use Xft fonts. It has
1247	antialiaisng disabled for most of them, because the author thinks they
1248	look best that way.
1249
1250	If you want antialiasing, you have to specify the fonts manually.
1251
1252	=item Mouse cut/paste suddenly no longer works.
1253
1254	Make sure that mouse reporting is actually turned off since killing
1255	some editors prematurely may leave the mouse in mouse report mode. I've
1256	heard that tcsh may use mouse reporting unless it otherwise specified. A
1257	quick check is to see if cut/paste works when the Alt or Shift keys are
1258	depressed. See @@RXVT_NAME@@(7)
1259
1260	=item What's with this bold/blink stuff?
1261
1262	If no bold colour is set via C<colorBD:>, bold will invert text using the
1263	standard foreground colour.
1264
1265	For the standard background colour, blinking will actually make the
1266	text blink when compiled with C<--enable-blinking>. with standard
1267	colours. Without C<--enable-blinking>, the blink attribute will be
1268	ignored.
1269
1270	On ANSI colours, bold/blink attributes are used to set high-intensity
1271	foreground/background colors.
1272
1273	color0-7 are the low-intensity colors.
1274
1275	color8-15 are the corresponding high-intensity colors.
1276
1277	=item I don't like the screen colors. How do I change them?
1278
1279	You can change the screen colors at run-time using F<~/.Xdefaults>
1280	resources (or as long-options).
1281
1282	Here are values that are supposed to resemble a VGA screen,
1283	including the murky brown that passes for low-intensity yellow:
1284
1285	Rxvt*color0: #000000
1286	Rxvt*color1: #A80000
1287	Rxvt*color2: #00A800
1288	Rxvt*color3: #A8A800
1289	Rxvt*color4: #0000A8
1290	Rxvt*color5: #A800A8
1291	Rxvt*color6: #00A8A8
1292	Rxvt*color7: #A8A8A8
1293
1294	Rxvt*color8: #000054
1295	Rxvt*color9: #FF0054
1296	Rxvt*color10: #00FF54
1297	Rxvt*color11: #FFFF54
1298	Rxvt*color12: #0000FF
1299	Rxvt*color13: #FF00FF
1300	Rxvt*color14: #00FFFF
1301	Rxvt*color15: #FFFFFF
1302
1303	=item What's with the strange Backspace/Delete key behaviour?
1304
1305	Assuming that the physical Backspace key corresponds to the
1306	BackSpace keysym (not likely for Linux ... see the following
1307	question) there are two standard values that can be used for
1308	Backspace: C<^H> and C<^?>.
1309
1310	Historically, either value is correct, but rxvt-unicode adopts the debian
1311	policy of using C<^?> when unsure, because it's the one only only correct
1312	choice :).
1313
1314	Rxvt-unicode tries to inherit the current stty settings and uses the value
1315	of `erase' to guess the value for backspace. If rxvt-unicode wasn't
1316	started from a terminal (say, from a menu or by remote shell), then the
1317	system value of `erase', which corresponds to CERASE in <termios.h>, will
1318	be used (which may not be the same as your stty setting).
1319
1320	For starting a new rxvt-unicode:
1321
1322	# use Backspace = ^H
1323	$ stty erase ^H
1324	$ @@RXVT_NAME@@
1325
1326	# use Backspace = ^?
1327	$ stty erase ^?
1328	$ @@RXVT_NAME@@
1329
1330	Toggle with "ESC[36h" / "ESC[36l" as documented in @@RXVT_NAME@@(7).
1331
1332	For an existing rxvt-unicode:
1333
1334	# use Backspace = ^H
1335	$ stty erase ^H
1336	$ echo -n "^[[36h"
1337
1338	# use Backspace = ^?
1339	$ stty erase ^?
1340	$ echo -n "^[[36l"
1341
1342	This helps satisfy some of the Backspace discrepancies that occur, but
1343	if you use Backspace = C<^H>, make sure that the termcap/terminfo value
1344	properly reflects that.
1345
1346	The Delete key is a another casualty of the ill-defined Backspace problem.
1347	To avoid confusion between the Backspace and Delete keys, the Delete
1348	key has been assigned an escape sequence to match the vt100 for Execute
1349	(ESC[3~) and is in the supplied termcap/terminfo.
1350
1351	Some other Backspace problems:
1352
1353	some editors use termcap/terminfo,
1354	some editors (vim I'm told) expect Backspace = ^H,
1355	GNU Emacs (and Emacs-like editors) use ^H for help.
1356
1357	Perhaps someday this will all be resolved in a consistent manner.
1358
1359	=item I don't like the key-bindings. How do I change them?
1360
1361	There are some compile-time selections available via configure. Unless
1362	you have run "configure" with the C<--disable-resources> option you can
1363	use the `keysym' resource to alter the keystrings associated with keysym
1364	0xFF00 - 0xFFFF (function, cursor keys, etc).
1365
1366	Here's an example for a tn3270 session started using `@@RXVT_NAME@@ -name tn3270'
1367

1407	=item I'm using keyboard model XXX that has extra Prior/Next/Insert keys.
1408	How do I make use of them? For example, the Sun Keyboard type 4
1409	has the following mappings that rxvt-unicode doesn't recognize.
1410
1411	KP_Insert == Insert
1412	F22 == Print
1413	F27 == Home
1414	F29 == Prior
1415	F33 == End
1416	F35 == Next
1417
1418	Rather than have rxvt-unicode try to accomodate all the various possible keyboard
1419	mappings, it is better to use `xmodmap' to remap the keys as required for
1420	your particular machine.
1421
1422	=item How do I distinguish if I'm running rxvt-unicode or a regular xterm?
1423	I need this to decide about setting colors etc.
1424
1425	rxvt and rxvt-unicode always export the variable "COLORTERM", so you can
1426	check and see if that is set. Note that several programs, JED, slrn,
1427	Midnight Commander automatically check this variable to decide whether or
1428	not to use color.
1429
1430	=item How do I set the correct, full IP address for the DISPLAY variable?
1431
1432	If you've compiled rxvt-unicode with DISPLAY_IS_IP and ahve enabled
1433	insecure mode then it is possible to use the following shell script
1434	snippets to correctly set the display. If your version of rxvt-unicode
1435	wasn't also compiled with ESCZ_ANSWER (as assumed in these snippets) then
1436	the COLORTERM variable can be used to distinguish rxvt-unicode from a
1437	regular xterm.
