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

		473	Tells @@RXVT_NAME@@ to embed its windows into an already-existing window,

		475
		476	Right now, @@RXVT_NAME@@ will first unmap/map the specified window, so it
		477	shouldn't be a top-level window. @@RXVT_NAME@@ will also reconfigure it
		478	quite a bit, so don't expect it to keep some specific state. It's best to
		479	create an extra subwindow for @@RXVT_NAME@@ and leave it alone.
		480
		481	The window will not be destroyed when @@RXVT_NAME@@ exits.
		482
		483	It might be useful to know that @@RXVT_NAME@@ will not close file
		484	descriptors passed to it (except for stdin/out/err, of course), so you
		485	can use file descriptors to communicate with the programs within the
		486	terminal. This works regardless of whether the C<-embed> option was used or
		487	not.
		488
		489	Here is a short Gtk2-perl snippet that illustrates how this option can be
		490	used (a longer example is in F<doc/embed>):
		491
		492	my $rxvt = new Gtk2::Socket;
		493	$rxvt->signal_connect_after (realize => sub {
		494	my $xid = $_[0]->window->get_xid;
		495	system "@@RXVT_NAME@@ -embed $xid &";
		496	});
		497
		498	=item B<-pty-fd> I<file descriptor>
		499
		500	Tells @@RXVT_NAME@@ NOT to execute any commands or create a new pty/tty
		501	pair but instead use the given file descriptor as the tty master. This is
		502	useful if you want to drive @@RXVT_NAME@@ as a generic terminal emulator
		503	without having to run a program within it.
		504
		505	If this switch is given, @@RXVT_NAME@@ will not create any utmp/wtmp
		506	entries and will not tinker with pty/tty permissions - you have to do that
		507	yourself if you want that.
		508
		509	As an extremely special case, specifying C<-1> will completely suppress
		510	pty/tty operations.
		511
		512	Here is a example in perl that illustrates how this option can be used (a
		513	longer example is in F<doc/pty-fd>):

		515	use IO::Pty;
		516	use Fcntl;
		517

		1104	B<2>, B<3>, B<4>, B<5>.
		1105
		1106	The B<NumLock>, B<Meta> and B<ISOLevel3> modifiers are usually aliased to
		1107	whatever modifier the NumLock key, Meta/Alt keys or ISO Level3 Shift/AltGr
		1108	keys are being mapped. B<AppKeypad> is a synthetic modifier mapped to the
		1109	current application keymap mode state.
		1110
		1111	The spellings of I<key> can be obtained by using B<xev>(1) command or
		1112	searching keysym macros from B</usr/X11R6/include/X11/keysymdef.h> and
		1113	omitting the prefix B<XK_>. Alternatively you can specify I<key> by its hex
		1114	keysym value (B<0x0000 - 0xFFFF>). Note that the lookup of I<sym>s is not
		1115	performed in an exact manner; however, the closest match is assured.
		1116
		1117	I<string> may contain escape values (C<\n>: newline, C<\000>: octal
		1118	number), see RESOURCES in C<man 7 X> for futher details.
		1119
		1120	You can define a range of keysyms in one shot by providing a I<string>
		1121	with pattern B<list/PREFIX/MIDDLE/SUFFIX>, where the delimiter `/'
		1122	should be a character not used by the strings.
		1123
		1124	Its usage can be demonstrated by an example:
		1125
		1126	URxvt.keysym.M-C-0x61: list|\033<M-C-|abc|>
		1127
		1128	The above line is equivalent to the following three lines:
		1129
		1130	URxvt.keysym.Meta-Control-0x61: \033<M-C-a>
		1131	URxvt.keysym.Meta-Control-0x62: \033<M-C-b>
		1132	URxvt.keysym.Meta-Control-0x63: \033<M-C-c>
		1133
		1134	If I<string> takes the form of C<command:STRING>, the specified B<STRING>
		1135	is interpreted and executed as @@RXVT_NAME@@'s control sequence. For
		1136	example the following means "change the current locale to C<zh_CN.GBK>
		1137	when Control-Meta-c is being pressed":
		1138
		1139	URxvt.keysym.M-C-c: command:\033]701;zh_CN.GBK\007
		1140
		1141	If I<string> takes the form C<perl:STRING>, then the specified B<STRING>
		1142	is passed to the C<on_keyboard_command> perl handler. See the @@RXVT_NAME@@perl(3)
		1143	manpage. For example, the F<selection> extension (activated via
		1144	C<@@RXVT_NAME@@ -pe selection>) listens for C<selection:rot13> events:
		1145
		1146	URxvt.keysym.M-C-c: perl:selection:rot13
		1147
		1148	Due the the large number of modifier combinations, a defined key mapping
		1149	will match if at I<at least> the specified identifiers are being set, and
		1150	no other key mappings with those and more bits are being defined. That
		1151	means that defining a key map for C<a> will automatically provide
		1152	definitions for C<Meta-a>, C<Shift-a> and so on, unless some of those are defined
		1153	mappings themselves.
		1154
		1155	Unfortunately, this will override built-in key mappings. For example
		1156	if you overwrite the C<Insert> key you will disable @@RXVT_NAME@@'s
		1157	C<Shift-Insert> mapping. To re-enable that, you can poke "holes" into the
		1158	user-defined keymap using the C<builtin:> replacement:
		1159
		1160	URxvt.keysym.Insert: <my insert key sequence>
		1161	URxvt.keysym.S-Insert: builtin:
		1162
		1163	The first line defines a mapping for C<Insert> and I<any> combination
		1164	of modifiers. The second line re-establishes the default mapping for
		1165	C<Shift-Insert>.
		1166
		1167	The following example will map Control-Meta-1 and Control-Meta-2 to
		1168	the fonts C<suxuseuro> and C<9x15bold>, so you can have some limited
		1169	font-switching at runtime:
		1170
		1171	URxvt.keysym.M-C-1: command:\033]50;suxuseuro\007
		1172	URxvt.keysym.M-C-2: command:\033]50;9x15bold\007
		1173
		1174	Other things are possible, e.g. resizing (see @@RXVT_NAME@@(7) for more
		1175	info):
		1176
		1177	URxvt.keysym.M-C-3: command:\033[8;25;80t

		1188	them. This can be useful to selectively disable some extensions loaded
		1189	by default, or specified via the C<perl-ext-common> resource. For
		1190	example, C<default,-selection> will use all the default extension except
		1191	C<selection>.
		1192
		1193	Extension names can also be followed by an argument in angle brackets
		1194	(e.g. C<< searchable-scrollback<M-s> >>, which binds the hotkey for
		1195	searchable scrollback to Alt/Meta-s). Mentioning the same extension

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@@	1553	@@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.
