		464	shouldn't be a top-level window. @@RXVT_NAME@@ will also reconfigure it
		465	quite a bit, so don't expect it to keep some specific state. It's best to
		466	create an extra subwindow for @@RXVT_NAME@@ and leave it alone.
		467
		468	The window will not be destroyed when @@RXVT_NAME@@ exits.
		469
		470	It might be useful to know that @@RXVT_NAME@@ will not close file
		471	descriptors passed to it (except for stdin/out/err, of course), so you
		472	can use file descriptors to communicate with the programs within the
		473	terminal. This works regardless of whether the C<-embed> option was used or
		474	not.
		475
		476	Here is a short Gtk2-perl snippet that illustrates how this option can be
		477	used (a longer example is in F<doc/embed>):
		478
		479	my $rxvt = new Gtk2::Socket;
		480	$rxvt->signal_connect_after (realize => sub {
		481	my $xid = $_[0]->window->get_xid;
		482	system "@@RXVT_NAME@@ -embed $xid &";
		483	});
		484
		485	=item B<-pty-fd> I<file descriptor>
		486
		487	Tells @@RXVT_NAME@@ NOT to execute any commands or create a new pty/tty
		488	pair but instead use the given file descriptor as the tty master. This is
		489	useful if you want to drive @@RXVT_NAME@@ as a generic terminal emulator
		490	without having to run a program within it.
		491
		492	If this switch is given, @@RXVT_NAME@@ will not create any utmp/wtmp
		493	entries and will not tinker with pty/tty permissions - you have to do that
		494	yourself if you want that.
		495
		496	As an extremely special case, specifying C<-1> will completely suppress
		497	pty/tty operations.
		498
		499	Here is a example in perl that illustrates how this option can be used (a
		500	longer example is in F<doc/pty-fd>):
		501
		502	use IO::Pty;
		503	use Fcntl;
		504
		505	my $pty = new IO::Pty;
		506	fcntl $pty, F_SETFD, 0; # clear close-on-exec
		507	system "@@RXVT_NAME@@ -pty-fd " . (fileno $pty) . "&";
		508	close $pty;

		1081	B<2>, B<3>, B<4>, B<5>.
		1082
		1083	The B<NumLock>, B<Meta> and B<ISOLevel3> modifiers are usually aliased to
		1084	whatever modifier the NumLock key, Meta/Alt keys or ISO Level3 Shift/AltGr
		1085	keys are being mapped. B<AppKeypad> is a synthetic modifier mapped to the
		1086	current application keymap mode state.
		1087
		1088	The spellings of I<key> can be obtained by using B<xev>(1) command or
		1089	searching keysym macros from B</usr/X11R6/include/X11/keysymdef.h> and
		1090	omitting the prefix B<XK_>. Alternatively you can specify I<key> by its hex
		1091	keysym value (B<0x0000 - 0xFFFF>). Note that the lookup of I<sym>s is not
		1092	performed in an exact manner; however, the closest match is assured.
		1093
		1094	I<string> may contain escape values (C<\n>: newline, C<\000>: octal
		1095	number), see RESOURCES in C<man 7 X> for futher details.
		1096
		1097	You can define a range of keysyms in one shot by providing a I<string>
		1098	with pattern B<list/PREFIX/MIDDLE/SUFFIX>, where the delimiter `/'
		1099	should be a character not used by the strings.
		1100
		1101	Its usage can be demonstrated by an example:
		1102
		1103	URxvt.keysym.M-C-0x61: list|\033<M-C-|abc|>
		1104
		1105	The above line is equivalent to the following three lines:
		1106
		1107	URxvt.keysym.Meta-Control-0x61: \033<M-C-a>
		1108	URxvt.keysym.Meta-Control-0x62: \033<M-C-b>
		1109	URxvt.keysym.Meta-Control-0x63: \033<M-C-c>
		1110
		1111	If I<string> takes the form of C<command:STRING>, the specified B<STRING>
		1112	is interpreted and executed as @@RXVT_NAME@@'s control sequence. For
		1113	example the following means "change the current locale to C<zh_CN.GBK>
		1114	when Control-Meta-c is being pressed":
		1115
		1116	URxvt.keysym.M-C-c: command:\033]701;zh_CN.GBK\007
		1117
		1118	If I<string> takes the form C<perl:STRING>, then the specified B<STRING>
		1119	is passed to the C<on_keyboard_command> perl handler. See the @@RXVT_NAME@@perl(3)
		1120	manpage. For example, the F<selection> extension (activated via
		1121	C<@@RXVT_NAME@@ -pe selection>) listens for C<selection:rot13> events:
		1122
		1123	URxvt.keysym.M-C-c: perl:selection:rot13
		1124
		1125	Due the the large number of modifier combinations, a defined key mapping
		1126	will match if at I<at least> the specified identifiers are being set, and
		1127	no other key mappings with those and more bits are being defined. That
		1128	means that defining a key map for C<a> will automatically provide
		1129	definitions for C<Meta-a>, C<Shift-a> and so on, unless some of those are defined
		1130	mappings themselves.
		1131
		1132	Unfortunately, this will override built-in key mappings. For example
		1133	if you overwrite the C<Insert> key you will disable @@RXVT_NAME@@'s
		1134	C<Shift-Insert> mapping. To re-enable that, you can poke "holes" into the
		1135	user-defined keymap using the C<builtin:> replacement:
		1136
		1137	URxvt.keysym.Insert: <my insert key sequence>
		1138	URxvt.keysym.S-Insert: builtin:
		1139
		1140	The first line defines a mapping for C<Insert> and I<any> combination
		1141	of modifiers. The second line re-establishes the default mapping for
		1142	C<Shift-Insert>.
		1143
		1144	The following example will map Control-Meta-1 and Control-Meta-2 to
		1145	the fonts C<suxuseuro> and C<9x15bold>, so you can have some limited
		1146	font-switching at runtime:
		1147
		1148	URxvt.keysym.M-C-1: command:\033]50;suxuseuro\007
		1149	URxvt.keysym.M-C-2: command:\033]50;9x15bold\007
		1150
		1151	Other things are possible, e.g. resizing (see @@RXVT_NAME@@(7) for more
		1152	info):
		1153
		1154	URxvt.keysym.M-C-3: command:\033[8;25;80t

		1166	by default, or specified via the C<perl-ext-common> resource. For
		1167	example, C<default,-selection> will use all the default extension except
		1168	C<selection>.
		1169
		1170	Extension names can also be followed by an argument in angle brackets
		1171	(e.g. C<< searchable-scrollback<M-s> >>, which binds the hotkey for

969	bad. In that case, select a font of your taste and add it to the font

973		1516

975	font. If the base font does not contain the character, it will go to the
976	next font, and so on.

982	=item Why do some chinese characters look so different than others?	1523	=item B<XAPPLRESDIR>
983		1524
984	This is because there is a difference between script and language --	1525	Directory where various X resource files are being located.
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		1526
994	The workaround is easy: just tag a chinese font at the end of your font	1527	=item B<XENVIRONMENT>
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.

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@@	1530	@@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.
