		493	Right now, @@RXVT_NAME@@ will first unmap/map the specified window, so it

		496	create an extra subwindow for @@RXVT_NAME@@ and leave it alone.
		497
		498	The window will not be destroyed when @@RXVT_NAME@@ exits.
		499
		500	It might be useful to know that @@RXVT_NAME@@ will not close file
		501	descriptors passed to it (except for stdin/out/err, of course), so you
		502	can use file descriptors to communicate with the programs within the
		503	terminal. This works regardless of whether the C<-embed> option was used or
		504	not.
		505
		506	Here is a short Gtk2-perl snippet that illustrates how this option can be
		507	used (a longer example is in F<doc/embed>):
		508
		509	my $rxvt = new Gtk2::Socket;
		510	$rxvt->signal_connect_after (realize => sub {
		511	my $xid = $_[0]->window->get_xid;

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

		519	useful if you want to drive @@RXVT_NAME@@ as a generic terminal emulator
		520	without having to run a program within it.
		521
		522	If this switch is given, @@RXVT_NAME@@ will not create any utmp/wtmp
		523	entries and will not tinker with pty/tty permissions - you have to do that
		524	yourself if you want that.
		525
		526	As an extremely special case, specifying C<-1> will completely suppress
		527	pty/tty operations, which is probably only useful in conjunction with some
		528	perl extension that manages the terminal.
		529
		530	Here is a example in perl that illustrates how this option can be used (a

		535

		1151

		1156
		1157	The spellings of I<key> can be obtained by using B<xev>(1) command or

		1162
		1163	I<string> may contain escape values (C<\n>: newline, C<\000>: octal

		1165
		1166	You can define a range of keysyms in one shot by providing a I<string>
		1167	with pattern B<list/PREFIX/MIDDLE/SUFFIX>, where the delimiter `/'
		1168	should be a character not used by the strings.
		1169
		1170	Its usage can be demonstrated by an example:
		1171
		1172	URxvt.keysym.M-C-0x61: list|\033<M-C-|abc|>
		1173
		1174	The above line is equivalent to the following three lines:

		1176	URxvt.keysym.Meta-Control-0x61: \033<M-C-a>
		1177	URxvt.keysym.Meta-Control-0x62: \033<M-C-b>
		1178	URxvt.keysym.Meta-Control-0x63: \033<M-C-c>
		1179
		1180	If I<string> takes the form of C<command:STRING>, the specified B<STRING>
		1181	is interpreted and executed as @@RXVT_NAME@@'s control sequence. For
		1182	example the following means "change the current locale to C<zh_CN.GBK>

		1186
		1187	If I<string> takes the form C<perl:STRING>, then the specified B<STRING>
		1188	is passed to the C<on_user_command> perl handler. See the @@RXVT_NAME@@perl(3)
		1189	manpage. For example, the F<selection> extension (activated via
		1190	C<@@RXVT_NAME@@ -pe selection>) listens for C<selection:rot13> events:
		1191
		1192	URxvt.keysym.M-C-c: perl:selection:rot13
		1193
		1194	Due the the large number of modifier combinations, a defined key mapping
		1195	will match if I<at least> the specified identifiers are being set, and
		1196	no other key mappings with those and more bits are being defined. That
		1197	means that defining a key map for C<a> will automatically provide
		1198	definitions for C<Meta-a>, C<Shift-a> and so on, unless some of those are defined
		1199	mappings themselves.
		1200
		1201	Unfortunately, this will override built-in key mappings. For example
		1202	if you overwrite the C<Insert> key you will disable @@RXVT_NAME@@'s
		1203	C<Shift-Insert> mapping. To re-enable that, you can poke "holes" into the
		1204	user-defined keymap using the C<builtin:> replacement:
		1205
		1206	URxvt.keysym.Insert: <my insert key sequence>
		1207	URxvt.keysym.S-Insert: builtin:
		1208
		1209	The first line defines a mapping for C<Insert> and I<any> combination
		1210	of modifiers. The second line re-establishes the default mapping for
		1211	C<Shift-Insert>.
		1212
		1213	The following example will map Control-Meta-1 and Control-Meta-2 to
		1214	the fonts C<suxuseuro> and C<9x15bold>, so you can have some limited
		1215	font-switching at runtime:
		1216

		1218	URxvt.keysym.M-C-2: command:\033]50;9x15bold\007

		1235	by default, or specified via the C<perl-ext-common> resource. For
		1236	example, C<default,-selection> will use all the default extension except
		1237	C<selection>.
		1238
		1239	Extension names can also be followed by an argument in angle brackets
		1240	(e.g. C<< searchable-scrollback<M-s> >>, which binds the hotkey for

		1518	=head2 ALPHA CHANNEL SUPPORT
		1519
		1520	If Xft support has been compiled in and as long as Xft/Xrender/X don't get
		1521	their act together, rxvt-unicode will do it's own alpha channel management:
		1522
		1523	You can prefix any colour with an opaqueness percentage enclosed in
		1524	brackets, i.e. C<[percent]>, where C<percent> is a decimal percentage
		1525	(0-100) that specifies the opacity of the colour, where C<0> is completely
		1526	transparent and C<100> is completely opaque. For example, C<[50]red> is a
		1527	half-transparent red, while C<[95]#00ff00> is an almost opaque green. This
		1528	is the recommended format to specify transparency values, and works with
		1529	all ways to specify a colour.
		1530
		1531	For complete control, rxvt-unicode also supports
		1532	C<rgba:rrrr/gggg/bbbb/aaaa> (exactly four hex digits/component) colour
		1533	specifications, where the additional C<aaaa> component specifies opacity
		1534	(alpha) values. The minimum value of C<0000> is completely transparent,
		1535	while C<ffff> is completely opaque). The two example colours from
		1536	earlier could also be specified as C<rgba:ff00/0000/0000/8000> and
		1537	C<rgba:0000/ff00/0000/f332>.
		1538
		1539	You probably need to specify B<"-depth 32">, too, to force a visual with
		1540	alpha channels, and have the luck that your X-server uses ARGB pixel
		1541	layout, as X is far from just supporting ARGB visuals out of the box, and
		1542	rxvt-unicode just fudges around.
		1543
		1544	For example, the following selects an almost completely transparent black
		1545	background, and an almost opaque pink foreground:
		1546
		1547	@@RXVT_NAME@@ -depth 32 -bg rgba:0000/0000/0000/4444 -fg "[80]pink"
		1548
		1549	When not using a background image, then the interpretation of the
		1550	alpha channel is up to your compositing manager (most interpret it as
		1551	transparency of course).

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.
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

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

1232	F35 == Next
1233

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
