39If you are looking for a terminal that supports more exotic scripts, let
40me recommend C<mlterm>, which is a very userfriendly, lean and clean
41terminal emulator. In fact, the reason rxvt-unicode was born was solely
42because the author couldn't get C<mlterm> to use one font for latin1 and
43another for japanese.

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::DrawingArea;

628the iso8859-1 version of the second font), which is the base font (because
629it is named first) and thus defines the character cell grid to be 9 pixels
630wide and 15 pixels high.
631
632The second font is just used to add additional unicode characters not in
633the base font, likewise the third, which is unfortunately non-bold, but
634the bold version of the font does contain less characters, so this is a
635useful supplement.
636
637The third font is an Xft font with aliasing turned off, and the characters
638are limited to the B<JIS 0208> codeset (i.e. japanese kanji). The font
639contains other characters, but we are not interested in them.

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

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
963The following example will map Control-Meta-1 and Control-Meta-2 to
964the fonts C<suxuseuro> and C<9x15bold>, so you can have some limited
965font-switching at runtime:

1045and character codes using the keyboard. It consists of 4 parts. The
1046first part is available rxvt-unicode has been compiled with

814key. 1055
1056Start by pressing and holding both C<Control> and C<Shift>, then enter
1057hex-digits (between one and six). Releasing C<Control> and C<Shift> will
1058commit the character as if it were typed directly. While holding down
1059C<Control> and C<Shift> you can also enter multiple characters by pressing
1060C<Space>, which will commit the current character and lets you start a new
1061one.
1062
1063As an example of use, imagine a business card with a japanese e-mail
1064address, which you cannot type. Fortunately, the card has the e-mail
1065address printed as hexcodes, e.g. C<671d 65e5>. You can enter this easily
1066by pressing C<Control> and C<Shift>, followed by C<6-7-1-D-SPACE-6-5-E-5>,
1067followed by releasing the modifier keys.
1068
1069=item * 5.2: Keyboard symbols entry method
1070
1071This mode lets you input characters representing the keycap symbols of
1072your keyboard, if representable in the current locale encoding.
1073
1074Start by pressing C<Control> and C<Shift> together, then releasing
1075them. The next special key (cursor keys, home etc.) you enter will not
1076invoke it's usual function but instead will insert the corresponding
1077keycap symbol. The symbol will only be entered when the key has been
1078released, otherwise pressing e.g. C<Shift> would enter the symbol for
1079C<ISO Level 2 Switch>, although your intention might have been to enter a
1080reverse tab (Shift-Tab).
1081
1082=item * 5.3: Screen-selection entry method
1083
1084While this is implemented already (it's basically the selection
1085mechanism), it could be extended by displaying a unicode character map.
1086
1087=item * 5.4: Feedback method for identifying displayed characters for later input
1088
1089This method lets you display the unicode character code associated with
1090characters already displayed.
1091
1092You enter this mode by holding down C<Control> and C<Shift> together, then
1093pressing and holding the left mouse button and moving around. The unicode
1094hex code(s) (it might be a combining character) of the character under the
1095pointer is displayed until you release C<Control> and C<Shift>.
1096
1097In addition to the hex codes it will display the font used to draw this
1098character - due to implementation reasons, characters combined with
1099combining characters, line drawing characters and unknown characters will
1100always be drawn using the built-in support font.

886Most fonts do not contain the full range of Unicode, which is 1180=item B<COLORFGBG>
887fine. Chances are that the font you (or the admin/package maintainer of
888your system/os) have specified does not cover all the characters you want
889to display.
890 1181
891B<rxvt-unicode> makes a best-effort try at finding a replacement 1182Set to a string of the form C<fg;bg> or C<fg;xpm;bg>, where C<fg> is

896 @@RXVT_NAME@@ -fn basefont,font2,font3... 1190=item B<WINDOWID>
897 1191
898When rxvt-unicode sees a character, it will first look at the base 1192Set to the (decimal) X Window ID of the @@RXVT_NAME@@ window (the toplevel
899font. If the base font does not contain the character, it will go to the 1193window, which usually has subwindows for the scrollbar, the terminal
900next font, and so on. 1194window and so on).
901 1195
902The only limitation is that all the fonts must not be larger than the base 1196=item B<TERMINFO>
903font, as the base font defines the principial cell size, which must be the
904same due to the way terminals work.
905 1197
906=item Why do some chinese characters look so different than others? 1198Set to the terminfo directory iff @@RXVT_NAME@@ was configured with
1199C<--with-terminfo=PATH>.
907 1200
908This is because there is a difference between script and language -- 1201=item B<DISPLAY>
909rxvt-unicode does not know which language the text that is output
910is, as it only knows the unicode character codes. If rxvt-unicode
911first sees a japanese character, it might choose a japanese font for
912it. Subseqzuent japanese characters will take that font. Now, many chinese
913characters aren't represented in japanese fonts, so when the first
914non-japanese character comes up, rxvt-unicode will look for a chinese font
915-- unfortunately at this point, it will still use the japanese font for
916japanese characters that are also chinese.
917 1202
918The workaround is easy: just tag a chinese font at the end of your font 1203Used by @@RXVT_NAME@@ to connect to the display and set to the correct
919list (see the previous question). The key is to view the font list as 1204display in it's child processes.
920a preference list: If you expect more japanese, list a japanese font
921first. If you expect more chinese, put a chinese font first.
922 1205
923In the future it might be possible to switch preferences at runtime (the 1206=item B<SHELL>
924internal data structure has no problem with using different fonts for
925the same character at the same time, but no interface for this has been
926designed yet).

931some editors prematurely may leave the mouse in mouse report mode. I've

936=item What's with this bold/blink stuff? 1212The path where @@RXVT_NAME@@ looks for support files such as menu and xpm
1213files.
937 1214
938If no bold colour is set via C<colorBD:>, bold will invert text using the 1215=item B<PATH>

979=item What's with the strange Backspace/Delete key behaviour? 1236=item B<XENVIRONMENT>
980 1237
981Assuming that the physical Backspace key corresponds to the 1238If set and accessible, gives the name of a X resource file to be loaded by
982BackSpace keysym (not likely for Linux ... see the following
983question) there are two standard values that can be used for
984Backspace: C<^H> and C<^?>.
985
986Historically, either value is correct, but rxvt-unicode adopts the debian
987policy of using C<^?> when unsure, because it's the one only only correct
988choice :).
989
990Rxvt-unicode tries to inherit the current stty settings and uses the value
991of `erase' to guess the value for backspace. If rxvt-unicode wasn't
992started from a terminal (say, from a menu or by remote shell), then the
993system value of `erase', which corresponds to CERASE in <termios.h>, will
994be used (which may not be the same as your stty setting).
995
996For starting a new rxvt-unicode:
997
998 # use Backspace = ^H
999 $ stty erase ^H
1000 $ @@RXVT_NAME@@ 1239@@RXVT_NAME@@.
1001
1002 # use Backspace = ^?
1003 $ stty erase ^?
1004 $ @@RXVT_NAME@@
1005
1006Toggle with "ESC[36h" / "ESC[36l" as documented in @@RXVT_NAME@@(7).
1007
1008For 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
1018This helps satisfy some of the Backspace discrepancies that occur, but
1019if you use Backspace = C<^H>, make sure that the termcap/terminfo value
1020properly reflects that.
1021
1022The Delete key is a another casualty of the ill-defined Backspace problem.
1023To avoid confusion between the Backspace and Delete keys, the Delete
1024key has been assigned an escape sequence to match the vt100 for Execute
1025(ESC[3~) and is in the supplied termcap/terminfo.
1026
1027Some other Backspace problems:
1028
1029some editors use termcap/terminfo,
1030some editors (vim I'm told) expect Backspace = ^H,
1031GNU Emacs (and Emacs-like editors) use ^H for help.
1032
1033Perhaps 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
1037There are some compile-time selections available via configure. Unless
1038you have run "configure" with the C<--disable-resources> option you can
1039use the `keysym' resource to alter the keystrings associated with keysym
10400xFF00 - 0xFFFF (function, cursor keys, etc).

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