379Tells @@RXVT_NAME@@ to embed it's windows into an already-existing window,
380which enables applications to easily embed a terminal.
381
382Right now, @@RXVT_NAME@@ will first unmap/map the specified window, so it
383shouldn't be a top-level window. @@RXVT_NAME@@ will also reconfigure it
384quite a bit, so don't expect it to keep some specific state. It's best to
385create an extra subwindow for @@RXVT_NAME@@ and leave it alone.
386
387The window will not be destroyed when @@RXVT_NAME@@ exits.
388
389It might be useful to know that @@RXVT_NAME@@ will not close file
390descriptors passed to it (except for stdin/out/err, of course), so you
391can use file descriptors to communicate with the programs within the
392terminal. This works regardless of wether the C<-embed> option was used or
393not.
394
395Here is a short Gtk2-perl snippet that illustrates how this option can be
396used (a longer example is in F<doc/embed>):
397
398 my $rxvt = new Gtk2::Socket;
399 $rxvt->signal_connect_after (realize => sub {
400 my $xid = $_[0]->window->get_xid;
401 system "@@RXVT_NAME@@ -embed $xid &";

406Tells @@RXVT_NAME@@ NOT to execute any commands or create a new pty/tty
407pair but instead use the given filehandle as the tty master. This is
408useful if you want to drive @@RXVT_NAME@@ as a generic terminal emulator
409without having to run a program within it.
410
411If this switch is given, @@RXVT_NAME@@ will not create any utmp/wtmp
412entries and will not tinker with pty/tty permissions - you have to do that
413yourself if you want that.
414
415Here is a example in perl that illustrates how this option can be used (a
416longer example is in F<doc/pty-fd>):
417
418 use IO::Pty;
419 use Fcntl;
420
421 my $pty = new IO::Pty;

914The format of I<sym> is "I<(modifiers-)key>", where I<modifiers> can be
915any combination of B<ISOLevel3>, B<AppKeypad>, B<Control>, B<NumLock>,
916B<Shift>, B<Meta>, B<Lock>, B<Mod1>, B<Mod2>, B<Mod3>, B<Mod4>, B<Mod5>,
917and the abbreviated B<I>, B<K>, B<C>, B<N>, B<S>, B<M>, B<A>, B<L>, B<1>,
918B<2>, B<3>, B<4>, B<5>.
919
920The B<NumLock>, B<Meta> and B<ISOLevel3> modifiers are usually aliased to
921whatever modifier the NumLock key, Meta/Alt keys or ISO Level3 Shift/AltGr
922keys are being mapped. B<AppKeypad> is a synthetic modifier mapped to the
923current application keymap mode state.
924
925The spellings of I<key> can be obtained by using B<xev>(1) command or
926searching keysym macros from B</usr/X11R6/include/X11/keysymdef.h> and
927omitting the prefix B<XK_>. Alternatively you can specify I<key> by its hex
928keysym value (B<0x0000 - 0xFFFF>). Note that the lookup of I<sym>s is not
929performed in an exact manner; however, the closest match is assured.
930
931I<string> may contain escape values (C<\a>: bell, C<\b>: backspace,
932C<\e>, C<\E>: escape, C<\n>: newline, C<\r>: carriage return, C<\t>: tab,

828omitted. This resource is only available when compiled with 936
829KEYSYM_RESOURCE. 937Please note that you need to double the C<\> when using
938C<--enable-xgetdefault>, as X itself does it's own de-escaping (you can
939use C<\033> instead of C<\e> (and so on), which will work with both Xt and
940@@RXVT_NAME@@'s own processing).
941
942You can define a range of keysyms in one shot by providing a I<string>
943with pattern B<list/PREFIX/MIDDLE/SUFFIX>, where the delimeter `/'
944should be a character not used by the strings.
945
946Its usage can be demonstrated by an example:
947
948 URxvt.keysym.M-C-0x61: list|\033<M-C-|abc|>
949
950The above line is equivalent to the following three lines:
951
952 URxvt.keysym.Meta-Control-0x61: \033<M-C-a>
953 URxvt.keysym.Meta-Control-0x62: \033<M-C-b>
954 URxvt.keysym.Meta-Control-0x63: \033<M-C-c>
955
956If I<string> takes the form of C<command:STRING>, the specified B<STRING>
957is interpreted and executed as @@RXVT_NAME@@'s control sequence. For
958example the following means "change the current locale to C<zh_CN.GBK>
959when Control-Meta-c is being pressed":
960
961 URxvt.keysym.M-C-c: command:\033]701;zh_CN.GBK\007
962
963Due the the large number of modifier combinations, a defined key mapping
964will match if at I<at least> the specified identifiers are being set, and
965no other key mappings with those and more bits are being defined. That
966means that defining a key map for C<a> will automatically provide
967definitions for C<Meta-a>, C<Shift-a> and so on, unless some of those are defined
968mappings themselves.
969
970Unfortunately, this will override built-in key mappings. For example
971if you overwrite the C<Insert> key you will disable @@RXVT_NAME@@'s
972C<Shift-Insert> mapping. To re-enable that, you can poke "holes" into the
973user-defined keymap using the C<builtin:> replacement:
974
975 URxvt.keysym.Insert: <my insert key sequence>
976 URxvt.keysym.S-Insert: builtin:
977
978The first line defines a mapping for C<Insert> and I<any> combination
979of modifiers. The second line re-establishes the default mapping for
980C<Shift-Insert>.
981
982The following example will map Control-Meta-1 and Control-Meta-2 to
983the fonts C<suxuseuro> and C<9x15bold>, so you can have some limited
984font-switching at runtime:
985
986 URxvt.keysym.M-C-1: command:\033]50;suxuseuro\007
987 URxvt.keysym.M-C-2: command:\033]50;9x15bold\007
988
989Other things are possible, e.g. resizing (see @@RXVT_NAME@@(7) for more
990info):
