		39	If you are looking for a terminal that supports more exotic scripts, let

		41	terminal emulator. In fact, the reason rxvt-unicode was born was solely

		473
		474	Right now, @@RXVT_NAME@@ will first unmap/map the specified window, so it
		475	shouldn't be a top-level window. @@RXVT_NAME@@ will also reconfigure it
		476	quite a bit, so don't expect it to keep some specific state. It's best to
		477	create an extra subwindow for @@RXVT_NAME@@ and leave it alone.
		478
		479	The window will not be destroyed when @@RXVT_NAME@@ exits.
		480
		481	It might be useful to know that @@RXVT_NAME@@ will not close file
		482	descriptors passed to it (except for stdin/out/err, of course), so you
		483	can use file descriptors to communicate with the programs within the
		484	terminal. This works regardless of whether the C<-embed> option was used or
		485	not.
		486
		487	Here is a short Gtk2-perl snippet that illustrates how this option can be
		488	used (a longer example is in F<doc/embed>):
		489
		490	my $rxvt = new Gtk2::Socket;
		491	$rxvt->signal_connect_after (realize => sub {
		492	my $xid = $_[0]->window->get_xid;

		498	Tells @@RXVT_NAME@@ NOT to execute any commands or create a new pty/tty
		499	pair but instead use the given file descriptor as the tty master. This is
		500	useful if you want to drive @@RXVT_NAME@@ as a generic terminal emulator
		501	without having to run a program within it.
		502
		503	If this switch is given, @@RXVT_NAME@@ will not create any utmp/wtmp
		504	entries and will not tinker with pty/tty permissions - you have to do that
		505	yourself if you want that.
		506
		507	As an extremely special case, specifying C<-1> will completely suppress
		508	pty/tty operations, which is probably only useful in conjunction with some
		509	perl extension that manages the terminal.
		510
		511	Here is a example in perl that illustrates how this option can be used (a

		1105	B<2>, B<3>, B<4>, B<5>.
		1106
		1107	The B<NumLock>, B<Meta> and B<ISOLevel3> modifiers are usually aliased to
		1108	whatever modifier the NumLock key, Meta/Alt keys or ISO Level3 Shift/AltGr
		1109	keys are being mapped. B<AppKeypad> is a synthetic modifier mapped to the
		1110	current application keymap mode state.
		1111
		1112	The spellings of I<key> can be obtained by using B<xev>(1) command or
		1113	searching keysym macros from B</usr/X11R6/include/X11/keysymdef.h> and
		1114	omitting the prefix B<XK_>. Alternatively you can specify I<key> by its hex
		1115	keysym value (B<0x0000 - 0xFFFF>). Note that the lookup of I<sym>s is not
		1116	performed in an exact manner; however, the closest match is assured.
		1117
		1118	I<string> may contain escape values (C<\n>: newline, C<\000>: octal
		1119	number), see RESOURCES in C<man 7 X> for futher details.
		1120
		1121	You can define a range of keysyms in one shot by providing a I<string>
		1122	with pattern B<list/PREFIX/MIDDLE/SUFFIX>, where the delimiter `/'
		1123	should be a character not used by the strings.
		1124
		1125	Its usage can be demonstrated by an example:
		1126
		1127	URxvt.keysym.M-C-0x61: list|\033<M-C-|abc|>
		1128
		1129	The above line is equivalent to the following three lines:
		1130
		1131	URxvt.keysym.Meta-Control-0x61: \033<M-C-a>
		1132	URxvt.keysym.Meta-Control-0x62: \033<M-C-b>
		1133	URxvt.keysym.Meta-Control-0x63: \033<M-C-c>
		1134
		1135	If I<string> takes the form of C<command:STRING>, the specified B<STRING>
		1136	is interpreted and executed as @@RXVT_NAME@@'s control sequence. For
		1137	example the following means "change the current locale to C<zh_CN.GBK>
		1138	when Control-Meta-c is being pressed":
		1139
		1140	URxvt.keysym.M-C-c: command:\033]701;zh_CN.GBK\007
		1141
		1142	If I<string> takes the form C<perl:STRING>, then the specified B<STRING>
		1143	is passed to the C<on_keyboard_command> perl handler. See the @@RXVT_NAME@@perl(3)
		1144	manpage. For example, the F<selection> extension (activated via
		1145	C<@@RXVT_NAME@@ -pe selection>) listens for C<selection:rot13> events:
		1146
		1147	URxvt.keysym.M-C-c: perl:selection:rot13
		1148
		1149	Due the the large number of modifier combinations, a defined key mapping
		1150	will match if at I<at least> the specified identifiers are being set, and
		1151	no other key mappings with those and more bits are being defined. That
		1152	means that defining a key map for C<a> will automatically provide
		1153	definitions for C<Meta-a>, C<Shift-a> and so on, unless some of those are defined
		1154	mappings themselves.
		1155
		1156	Unfortunately, this will override built-in key mappings. For example
		1157	if you overwrite the C<Insert> key you will disable @@RXVT_NAME@@'s
		1158	C<Shift-Insert> mapping. To re-enable that, you can poke "holes" into the
		1159	user-defined keymap using the C<builtin:> replacement:
		1160
		1161	URxvt.keysym.Insert: <my insert key sequence>
		1162	URxvt.keysym.S-Insert: builtin:
		1163
		1164	The first line defines a mapping for C<Insert> and I<any> combination
		1165	of modifiers. The second line re-establishes the default mapping for
		1166	C<Shift-Insert>.
		1167
		1168	The following example will map Control-Meta-1 and Control-Meta-2 to
		1169	the fonts C<suxuseuro> and C<9x15bold>, so you can have some limited
		1170	font-switching at runtime:
		1171
		1172	URxvt.keysym.M-C-1: command:\033]50;suxuseuro\007
		1173	URxvt.keysym.M-C-2: command:\033]50;9x15bold\007
		1174
		1175	Other things are possible, e.g. resizing (see @@RXVT_NAME@@(7) for more
		1176	info):
		1177
		1178	URxvt.keysym.M-C-3: command:\033[8;25;80t

		1190	by default, or specified via the C<perl-ext-common> resource. For
		1191	example, C<default,-selection> will use all the default extension except
		1192	C<selection>.
		1193
		1194	Extension names can also be followed by an argument in angle brackets
		1195	(e.g. C<< searchable-scrollback<M-s> >>, which binds the hotkey for

979	=item What's with the strange Backspace/Delete key behaviour?
980
981	Assuming that the physical Backspace key corresponds to the
982	BackSpace keysym (not likely for Linux ... see the following
983	question) there are two standard values that can be used for
984	Backspace: C<^H> and C<^?>.
985
986	Historically, either value is correct, but rxvt-unicode adopts the debian
987	policy of using C<^?> when unsure, because it's the one only only correct
988	choice :).
989
990	Rxvt-unicode tries to inherit the current stty settings and uses the value
991	of `erase' to guess the value for backspace. If rxvt-unicode wasn't
992	started from a terminal (say, from a menu or by remote shell), then the
993	system value of `erase', which corresponds to CERASE in <termios.h>, will
994	be used (which may not be the same as your stty setting).
995
996	For starting a new rxvt-unicode:
997
998	# use Backspace = ^H
999	$ stty erase ^H
1000	$ @@RXVT_NAME@@	1554	@@RXVT_NAME@@.
1001
1002	# use Backspace = ^?
1003	$ stty erase ^?
1004	$ @@RXVT_NAME@@
1005
1006	Toggle with "ESC[36h" / "ESC[36l" as documented in @@RXVT_NAME@@(7).
1007
1008	For an existing rxvt-unicode:
1009
1010	# use Backspace = ^H
1011	$ stty erase ^H
1012	$ echo -n "^[[36h"
1013
1014	# use Backspace = ^?
1015	$ stty erase ^?
1016	$ echo -n "^[[36l"
1017
1018	This helps satisfy some of the Backspace discrepancies that occur, but
1019	if you use Backspace = C<^H>, make sure that the termcap/terminfo value
1020	properly reflects that.
1021
1022	The Delete key is a another casualty of the ill-defined Backspace problem.
1023	To avoid confusion between the Backspace and Delete keys, the Delete
1024	key has been assigned an escape sequence to match the vt100 for Execute
1025	(ESC[3~) and is in the supplied termcap/terminfo.
1026
1027	Some other Backspace problems:
1028
1029	some editors use termcap/terminfo,
1030	some editors (vim I'm told) expect Backspace = ^H,
1031	GNU Emacs (and Emacs-like editors) use ^H for help.
1032
1033	Perhaps someday this will all be resolved in a consistent manner.
1034
1035	=item I don't like the key-bindings. How do I change them?
1036
1037	There are some compile-time selections available via configure. Unless
1038	you have run "configure" with the C<--disable-resources> option you can
1039	use the `keysym' resource to alter the keystrings associated with keysym
1040	0xFF00 - 0xFFFF (function, cursor keys, etc).
1041
1042	Here's an example for a tn3270 session started using `@@RXVT_NAME@@ -name tn3270'

1083	=item I'm using keyboard model XXX that has extra Prior/Next/Insert keys.
1084	How do I make use of them? For example, the Sun Keyboard type 4
1085	has the following mappings that rxvt-unicode doesn't recognize.
1086
1087	KP_Insert == Insert
1088	F22 == Print
1089	F27 == Home
1090	F29 == Prior
1091	F33 == End
1092	F35 == Next
1093
1094	Rather than have rxvt-unicode try to accomodate all the various possible keyboard
1095	mappings, it is better to use `xmodmap' to remap the keys as required for
1096	your particular machine.
1097
1098	=item How do I distinguish if I'm running rxvt-unicode or a regular xterm?
1099	I need this to decide about setting colors etc.
1100
1101	rxvt and rxvt-unicode always export the variable "COLORTERM", so you can
1102	check and see if that is set. Note that several programs, JED, slrn,
1103	Midnight Commander automatically check this variable to decide whether or
1104	not to use color.
1105
1106	=item How do I set the correct, full IP address for the DISPLAY variable?
1107
1108	If you've compiled rxvt-unicode with DISPLAY_IS_IP and ahve enabled
1109	insecure mode then it is possible to use the following shell script
1110	snippets to correctly set the display. If your version of rxvt-unicode
1111	wasn't also compiled with ESCZ_ANSWER (as assumed in these snippets) then
1112	the COLORTERM variable can be used to distinguish rxvt-unicode from a
1113	regular xterm.
