24=head1 RXVT-UNICODE/URXVT FREQUENTLY ASKED QUESTIONS
25
26
27=head2 Meta, Features & Commandline Issues
28
29=head3 My question isn't answered here, can I ask a human?
30
31Before sending me mail, you could go to IRC: C<irc.freenode.net>,
32channel C<#rxvt-unicode> has some rxvt-unicode enthusiasts that might be
33interested in learning about new and exciting problems (but not FAQs :).
34
35=head3 Does it support tabs, can I have a tabbed rxvt-unicode?
36
37Beginning with version 7.3, there is a perl extension that implements a
38simple tabbed terminal. It is installed by default, so any of these should
39give you tabs:
40
41 @@URXVT_NAME@@ -pe tabbed
42
43 URxvt.perl-ext-common: default,tabbed
44
45It will also work fine with tabbing functionality of many window managers
46or similar tabbing programs, and its embedding-features allow it to be
47embedded into other programs, as witnessed by F<doc/rxvt-tabbed> or
48the upcoming C<Gtk2::URxvt> perl module, which features a tabbed urxvt
49(murxvt) terminal as an example embedding application.
50
51=head3 How do I know which rxvt-unicode version I'm using?
52
53The version number is displayed with the usage (-h). Also the escape
54sequence C<ESC [ 8 n> sets the window title to the version number. When
55using the @@URXVT_NAME@@c client, the version displayed is that of the
56daemon.
57
58=head3 Rxvt-unicode uses gobs of memory, how can I reduce that?
59
60Rxvt-unicode tries to obey the rule of not charging you for something you
61don't use. One thing you should try is to configure out all settings that
62you don't need, for example, Xft support is a resource hog by design,
63when used. Compiling it out ensures that no Xft font will be loaded
64accidentally when rxvt-unicode tries to find a font for your characters.
65
66Also, many people (me included) like large windows and even larger
67scrollback buffers: Without C<--enable-unicode3>, rxvt-unicode will use
686 bytes per screen cell. For a 160x?? window this amounts to almost a
69kilobyte per line. A scrollback buffer of 10000 lines will then (if full)
70use 10 Megabytes of memory. With C<--enable-unicode3> it gets worse, as
71rxvt-unicode then uses 8 bytes per screen cell.
72
73=head3 How can I start @@URXVT_NAME@@d in a race-free way?
74
75Try C<@@URXVT_NAME@@d -f -o>, which tells @@URXVT_NAME@@d to open the
76display, create the listening socket and then fork.
77
78=head3 How can I start @@URXVT_NAME@@d automatically when I run URXVT_NAME@@c?
79
80If you want to start @@URXVT_NAME@@d automatically whenever you run
81@@URXVT_NAME@@c and the daemon isn't running yet, use this script:
82
83 #!/bin/sh
84 @@URXVT_NAME@@c "$@"
85 if [ $? -eq 2 ]; then
86 @@URXVT_NAME@@d -q -o -f
87 @@URXVT_NAME@@c "$@"
88 fi
89
90This tries to create a new terminal, and if fails with exit status 2,
91meaning it couldn't connect to the daemon, it will start the daemon and
92re-run the command. Subsequent invocations of the script will re-use the
93existing daemon.
94
95=head3 How do I distinguish whether I'm running rxvt-unicode or a regular xterm? I need this to decide about setting colors etc.
96
97The original rxvt and rxvt-unicode always export the variable "COLORTERM",
98so you can check and see if that is set. Note that several programs, JED,
99slrn, Midnight Commander automatically check this variable to decide
100whether or not to use color.
101
102=head3 How do I set the correct, full IP address for the DISPLAY variable?
103
104If you've compiled rxvt-unicode with DISPLAY_IS_IP and have enabled
105insecure mode then it is possible to use the following shell script
106snippets to correctly set the display. If your version of rxvt-unicode
107wasn't also compiled with ESCZ_ANSWER (as assumed in these snippets) then
108the COLORTERM variable can be used to distinguish rxvt-unicode from a
109regular xterm.
110
111Courtesy of Chuck Blake <cblake@BBN.COM> with the following shell script
112snippets:
113
114 # Bourne/Korn/POSIX family of shells:
115 [ ${TERM:-foo} = foo ] && TERM=xterm # assume an xterm if we don't know
116 if [ ${TERM:-foo} = xterm ]; then
117 stty -icanon -echo min 0 time 15 # see if enhanced rxvt or not
118 echo -n '^[Z'

121 if [ ""${term_id} = '^[[?1;2C' -a ${DISPLAY:-foo} = foo ]; then
122 echo -n '^[[7n' # query the rxvt we are in for the DISPLAY string
123 read DISPLAY # set it in our local shell
124 fi
125 fi
126
127=head3 How do I compile the manual pages on my own?
128
129You need to have a recent version of perl installed as F</usr/bin/perl>,
130one that comes with F<pod2man>, F<pod2text> and F<pod2html>. Then go to
131the doc subdirectory and enter C<make alldoc>.
132
133=head3 Isn't rxvt-unicode supposed to be small? Don't all those features bloat?
134
135I often get asked about this, and I think, no, they didn't cause extra
136bloat. If you compare a minimal rxvt and a minimal urxvt, you can see
137that the urxvt binary is larger (due to some encoding tables always being
138compiled in), but it actually uses less memory (RSS) after startup. Even
139with C<--disable-everything>, this comparison is a bit unfair, as many
140features unique to urxvt (locale, encoding conversion, iso14755 etc.) are
141already in use in this mode.
142
143 text data bss drs rss filename
144 98398 1664 24 15695 1824 rxvt --disable-everything
145 188985 9048 66616 18222 1788 urxvt --disable-everything
146
147When you C<--enable-everything> (which I<is> unfair, as this involves xft
148and full locale/XIM support which are quite bloaty inside libX11 and my
149libc), the two diverge, but not unreasonably so.
150
151 text data bss drs rss filename
152 163431 2152 24 20123 2060 rxvt --enable-everything
153 1035683 49680 66648 29096 3680 urxvt --enable-everything
154
155The very large size of the text section is explained by the east-asian
156encoding tables, which, if unused, take up disk space but nothing else
157and can be compiled out unless you rely on X11 core fonts that use those
158encodings. The BSS size comes from the 64k emergency buffer that my c++
159compiler allocates (but of course doesn't use unless you are out of
160memory). Also, using an xft font instead of a core font immediately adds a
161few megabytes of RSS. Xft indeed is responsible for a lot of RSS even when
162not used.
163
164Of course, due to every character using two or four bytes instead of one,
165a large scrollback buffer will ultimately make rxvt-unicode use more
166memory.
167
168Compared to e.g. Eterm (5112k), aterm (3132k) and xterm (4680k), this
169still fares rather well. And compared to some monsters like gnome-terminal
170(21152k + extra 4204k in separate processes) or konsole (22200k + extra
17143180k in daemons that stay around after exit, plus half a minute of
172startup time, including the hundreds of warnings it spits out), it fares
173extremely well *g*.
174
175=head3 Why C++, isn't that unportable/bloated/uncool?
176
177Is this a question? :) It comes up very often. The simple answer is: I had
178to write it, and C++ allowed me to write and maintain it in a fraction
179of the time and effort (which is a scarce resource for me). Put even
180shorter: It simply wouldn't exist without C++.
181
182My personal stance on this is that C++ is less portable than C, but in
183the case of rxvt-unicode this hardly matters, as its portability limits
184are defined by things like X11, pseudo terminals, locale support and unix
185domain sockets, which are all less portable than C++ itself.
186
187Regarding the bloat, see the above question: It's easy to write programs
188in C that use gobs of memory, an certainly possible to write programs in
189C++ that don't. C++ also often comes with large libraries, but this is
190not necessarily the case with GCC. Here is what rxvt links against on my
191system with a minimal config:
192
193 libX11.so.6 => /usr/X11R6/lib/libX11.so.6 (0x00002aaaaabc3000)
194 libc.so.6 => /lib/libc.so.6 (0x00002aaaaadde000)
195 libdl.so.2 => /lib/libdl.so.2 (0x00002aaaab01d000)
196 /lib64/ld-linux-x86-64.so.2 (0x00002aaaaaaab000)
197
198And here is rxvt-unicode:
199
200 libX11.so.6 => /usr/X11R6/lib/libX11.so.6 (0x00002aaaaabc3000)
201 libgcc_s.so.1 => /lib/libgcc_s.so.1 (0x00002aaaaada2000)
202 libc.so.6 => /lib/libc.so.6 (0x00002aaaaaeb0000)
203 libdl.so.2 => /lib/libdl.so.2 (0x00002aaaab0ee000)
204 /lib64/ld-linux-x86-64.so.2 (0x00002aaaaaaab000)
205
206No large bloated libraries (of course, none were linked in statically),
207except maybe libX11 :)
208
209
210=head2 Rendering, Font & Look and Feel Issues
211
212=head3 I can't get transparency working, what am I doing wrong?
213
214First of all, transparency isn't officially supported in rxvt-unicode, so
215you are mostly on your own. Do not bug the author about it (but you may
216bug everybody else). Also, if you can't get it working consider it a rite
217of passage: ... and you failed.
218
219Here are four ways to get transparency. B<Do> read the manpage and option
220descriptions for the programs mentioned and rxvt-unicode. Really, do it!
221
2221. Use inheritPixmap:
223
224 Esetroot wallpaper.jpg
225 @@URXVT_NAME@@ -ip -tint red -sh 40
226
227That works. If you think it doesn't, you lack transparency and tinting
228support, or you are unable to read.
229
2302. Use a simple pixmap and emulate pseudo-transparency. This enables you
231to use effects other than tinting and shading: Just shade/tint/whatever
232your picture with gimp or any other tool:
233
234 convert wallpaper.jpg -blur 20x20 -modulate 30 background.xpm
235 @@URXVT_NAME@@ -pixmap background.xpm -pe automove-background
236
237That works. If you think it doesn't, you lack XPM and Perl support, or you
238are unable to read.
239
2403. Use an ARGB visual:
241
242 @@URXVT_NAME@@ -depth 32 -fg grey90 -bg rgba:0000/0000/4444/cccc
243
244This requires XFT support, and the support of your X-server. If that
245doesn't work for you, blame Xorg and Keith Packard. ARGB visuals aren't
246there yet, no matter what they claim. Rxvt-Unicode contains the necessary
247bugfixes and workarounds for Xft and Xlib to make it work, but that
248doesn't mean that your WM has the required kludges in place.
249
2504. Use xcompmgr and let it do the job:
251
252 xprop -frame -f _NET_WM_WINDOW_OPACITY 32c \
253 -set _NET_WM_WINDOW_OPACITY 0xc0000000
254
255Then click on a window you want to make transparent. Replace C<0xc0000000>
256by other values to change the degree of opacity. If it doesn't work and
257your server crashes, you got to keep the pieces.
258
259=head3 Why does rxvt-unicode sometimes leave pixel droppings?
260
261Most fonts were not designed for terminal use, which means that character
262size varies a lot. A font that is otherwise fine for terminal use might
263contain some characters that are simply too wide. Rxvt-unicode will avoid
264these characters. For characters that are just "a bit" too wide a special
265"careful" rendering mode is used that redraws adjacent characters.
266
267All of this requires that fonts do not lie about character sizes,
268however: Xft fonts often draw glyphs larger than their acclaimed bounding
269box, and rxvt-unicode has no way of detecting this (the correct way is to
270ask for the character bounding box, which unfortunately is wrong in these
271cases).
272
273It's not clear (to me at least), whether this is a bug in Xft, freetype,
274or the respective font. If you encounter this problem you might try using
275the C<-lsp> option to give the font more height. If that doesn't work, you
276might be forced to use a different font.
277
278All of this is not a problem when using X11 core fonts, as their bounding
279box data is correct.
280
281=head3 How can I keep rxvt-unicode from using reverse video so much?
282
283First of all, make sure you are running with the right terminal settings
284(C<TERM=rxvt-unicode>), which will get rid of most of these effects. Then
285make sure you have specified colours for italic and bold, as otherwise
286rxvt-unicode might use reverse video to simulate the effect:
287
288 URxvt.colorBD: white
289 URxvt.colorIT: green
290
291=head3 Some programs assume totally weird colours (red instead of blue), how can I fix that?
292
293For some unexplainable reason, some rare programs assume a very weird
294colour palette when confronted with a terminal with more than the standard
2958 colours (rxvt-unicode supports 88). The right fix is, of course, to fix
296these programs not to assume non-ISO colours without very good reasons.
297
298In the meantime, you can either edit your C<rxvt-unicode> terminfo
299definition to only claim 8 colour support or use C<TERM=rxvt>, which will
300fix colours but keep you from using other rxvt-unicode features.
301
302=head3 Can I switch the fonts at runtime?
303
304Yes, using an escape sequence. Try something like this, which has the same
305effect as using the C<-fn> switch, and takes effect immediately:
306
307 printf '\33]50;%s\007' "9x15bold,xft:Kochi Gothic"
308
309This is useful if you e.g. work primarily with japanese (and prefer a
310japanese font), but you have to switch to chinese temporarily, where
311japanese fonts would only be in your way.
312
313You can think of this as a kind of manual ISO-2022 switching.
314
315=head3 Why do italic characters look as if clipped?
316
317Many fonts have difficulties with italic characters and hinting. For
318example, the otherwise very nicely hinted font C<xft:Bitstream Vera Sans
319Mono> completely fails in its italic face. A workaround might be to
320enable freetype autohinting, i.e. like this:
321
322 URxvt.italicFont: xft:Bitstream Vera Sans Mono:italic:autohint=true
323 URxvt.boldItalicFont: xft:Bitstream Vera Sans Mono:bold:italic:autohint=true
324
325=head3 Can I speed up Xft rendering somehow?
326
327Yes, the most obvious way to speed it up is to avoid Xft entirely, as
328it is simply slow. If you still want Xft fonts you might try to disable
329antialiasing (by appending C<:antialias=false>), which saves lots of
330memory and also speeds up rendering considerably.
331
332=head3 Rxvt-unicode doesn't seem to anti-alias its fonts, what is wrong?
333
334Rxvt-unicode will use whatever you specify as a font. If it needs to
335fall back to its default font search list it will prefer X11 core
336fonts, because they are small and fast, and then use Xft fonts. It has
337antialiasing disabled for most of them, because the author thinks they
338look best that way.
339
340If you want antialiasing, you have to specify the fonts manually.
341
342=head3 What's with this bold/blink stuff?
343
344If no bold colour is set via C<colorBD:>, bold will invert text using the
345standard foreground colour.
346
347For the standard background colour, blinking will actually make the
348text blink when compiled with C<--enable-blinking>. with standard
349colours. Without C<--enable-blinking>, the blink attribute will be
350ignored.
351
352On ANSI colours, bold/blink attributes are used to set high-intensity
353foreground/background colors.
354
355color0-7 are the low-intensity colors.
356
357color8-15 are the corresponding high-intensity colors.
358
359=head3 I don't like the screen colors. How do I change them?
360
361You can change the screen colors at run-time using F<~/.Xdefaults>
362resources (or as long-options).
363
364Here are values that are supposed to resemble a VGA screen,
365including the murky brown that passes for low-intensity yellow:
366
367 URxvt.color0: #000000
368 URxvt.color1: #A80000
369 URxvt.color2: #00A800
370 URxvt.color3: #A8A800
371 URxvt.color4: #0000A8
372 URxvt.color5: #A800A8
373 URxvt.color6: #00A8A8
374 URxvt.color7: #A8A8A8
375
376 URxvt.color8: #000054
377 URxvt.color9: #FF0054
378 URxvt.color10: #00FF54
379 URxvt.color11: #FFFF54
380 URxvt.color12: #0000FF
381 URxvt.color13: #FF00FF
382 URxvt.color14: #00FFFF
383 URxvt.color15: #FFFFFF
384
385And here is a more complete set of non-standard colors.
386
387 URxvt.cursorColor: #dc74d1
388 URxvt.pointerColor: #dc74d1
389 URxvt.background: #0e0e0e
390 URxvt.foreground: #4ad5e1
391 URxvt.color0: #000000
392 URxvt.color8: #8b8f93
393 URxvt.color1: #dc74d1
394 URxvt.color9: #dc74d1
395 URxvt.color2: #0eb8c7
396 URxvt.color10: #0eb8c7
397 URxvt.color3: #dfe37e
398 URxvt.color11: #dfe37e
399 URxvt.color5: #9e88f0
400 URxvt.color13: #9e88f0
401 URxvt.color6: #73f7ff
402 URxvt.color14: #73f7ff
403 URxvt.color7: #e1dddd
404 URxvt.color15: #e1dddd
405
406They have been described (not by me) as "pretty girly".
407
408=head3 Why do some characters look so much different than others?
409
410See next entry.
411
412=head3 How does rxvt-unicode choose fonts?
413
414Most fonts do not contain the full range of Unicode, which is
415fine. Chances are that the font you (or the admin/package maintainer of
416your system/os) have specified does not cover all the characters you want
417to display.
418
419B<rxvt-unicode> makes a best-effort try at finding a replacement
420font. Often the result is fine, but sometimes the chosen font looks
421bad/ugly/wrong. Some fonts have totally strange characters that don't
422resemble the correct glyph at all, and rxvt-unicode lacks the artificial
423intelligence to detect that a specific glyph is wrong: it has to believe
424the font that the characters it claims to contain indeed look correct.
425
426In that case, select a font of your taste and add it to the font list,
427e.g.:
428
429 @@URXVT_NAME@@ -fn basefont,font2,font3...
430
431When rxvt-unicode sees a character, it will first look at the base
432font. If the base font does not contain the character, it will go to the
433next font, and so on. Specifying your own fonts will also speed up this
434search and use less resources within rxvt-unicode and the X-server.
435
436The only limitation is that none of the fonts may be larger than the base
437font, as the base font defines the terminal character cell size, which
438must be the same due to the way terminals work.
439
440=head3 Why do some chinese characters look so different than others?
441
442This is because there is a difference between script and language --
443rxvt-unicode does not know which language the text that is output is,
444as it only knows the unicode character codes. If rxvt-unicode first
445sees a japanese/chinese character, it might choose a japanese font for
446display. Subsequent japanese characters will use that font. Now, many
447chinese characters aren't represented in japanese fonts, so when the first
448non-japanese character comes up, rxvt-unicode will look for a chinese font
449-- unfortunately at this point, it will still use the japanese font for
450chinese characters that are also in the japanese font.
451
452The workaround is easy: just tag a chinese font at the end of your font
453list (see the previous question). The key is to view the font list as
454a preference list: If you expect more japanese, list a japanese font
455first. If you expect more chinese, put a chinese font first.
456
457In the future it might be possible to switch language preferences at
458runtime (the internal data structure has no problem with using different
459fonts for the same character at the same time, but no interface for this
460has been designed yet).
461
462Until then, you might get away with switching fonts at runtime (see L<Can
463I switch the fonts at runtime?> later in this document).
464
465=head2 Keyboard, Mouse & User Interaction
466
467=head3 The new selection selects pieces that are too big, how can I select single words?
468
469If you want to select e.g. alphanumeric words, you can use the following
470setting:
471
472 URxvt.selection.pattern-0: ([[:word:]]+)
473
474If you click more than twice, the selection will be extended
475more and more.
476
477To get a selection that is very similar to the old code, try this pattern:
478
479 URxvt.selection.pattern-0: ([^"&'()*,;<=>?@[\\\\]^`{|})]+)
480
481Please also note that the I<LeftClick Shift-LeftClik> combination also
482selects words like the old code.
483
484=head3 I don't like the new selection/popups/hotkeys/perl, how do I change/disable it?
485
486You can disable the perl extension completely by setting the
487B<perl-ext-common> resource to the empty string, which also keeps
488rxvt-unicode from initialising perl, saving memory.
489
490If you only want to disable specific features, you first have to
491identify which perl extension is responsible. For this, read the section
492B<PREPACKAGED EXTENSIONS> in the @@URXVT_NAME@@perl(3) manpage. For
493example, to disable the B<selection-popup> and B<option-popup>, specify
494this B<perl-ext-common> resource:
495
496 URxvt.perl-ext-common: default,-selection-popup,-option-popup
497
498This will keep the default extensions, but disable the two popup
499extensions. Some extensions can also be configured, for example,
500scrollback search mode is triggered by B<M-s>. You can move it to any
501other combination either by setting the B<searchable-scrollback> resource:
502
503 URxvt.searchable-scrollback: CM-s
504
505=head3 The cursor moves when selecting text in the current input line, how do I switch this off?
506
507See next entry.
508
509=head3 During rlogin/ssh/telnet/etc. sessions, clicking near the cursor outputs strange escape sequences, how do I fix this?
510
511These are caused by the C<readline> perl extension. Under normal
512circumstances, it will move your cursor around when you click into the
513line that contains it. It tries hard not to do this at the wrong moment,
514but when running a program that doesn't parse cursor movements or in some
515cases during rlogin sessions, it fails to detect this properly.
516
517You can permanently switch this feature off by disabling the C<readline>
518extension:
519
520 URxvt.perl-ext-common: default,-readline
521
522=head3 My numerical keypad acts weird and generates differing output?
523
524Some Debian GNUL/Linux users seem to have this problem, although no
525specific details were reported so far. It is possible that this is caused
526by the wrong C<TERM> setting, although the details of whether and how
527this can happen are unknown, as C<TERM=rxvt> should offer a compatible
528keymap. See the answer to the previous question, and please report if that
529helped.
530
531=head3 My Compose (Multi_key) key is no longer working.
532
533The most common causes for this are that either your locale is not set
534correctly, or you specified a B<preeditStyle> that is not supported by
535your input method. For example, if you specified B<OverTheSpot> and
536your input method (e.g. the default input method handling Compose keys)
537does not support this (for instance because it is not visual), then
538rxvt-unicode will continue without an input method.
539
540In this case either do not specify a B<preeditStyle> or specify more than
541one pre-edit style, such as B<OverTheSpot,Root,None>.
542
543=head3 I cannot type C<Ctrl-Shift-2> to get an ASCII NUL character due to ISO 14755
544
545Either try C<Ctrl-2> alone (it often is mapped to ASCII NUL even on
546international keyboards) or simply use ISO 14755 support to your
547advantage, typing <Ctrl-Shift-0> to get a ASCII NUL. This works for other
548codes, too, such as C<Ctrl-Shift-1-d> to type the default telnet escape
549character and so on.
550
551=head3 Mouse cut/paste suddenly no longer works.
552
553Make sure that mouse reporting is actually turned off since killing
554some editors prematurely may leave the mouse in mouse report mode. I've
555heard that tcsh may use mouse reporting unless it otherwise specified. A
556quick check is to see if cut/paste works when the Alt or Shift keys are
557depressed.
558
559=head3 What's with the strange Backspace/Delete key behaviour?
560
561Assuming that the physical Backspace key corresponds to the
562Backspace keysym (not likely for Linux ... see the following
563question) there are two standard values that can be used for
564Backspace: C<^H> and C<^?>.
565
566Historically, either value is correct, but rxvt-unicode adopts the debian
567policy of using C<^?> when unsure, because it's the one only only correct
568choice :).
569
570Rxvt-unicode tries to inherit the current stty settings and uses the value
571of `erase' to guess the value for backspace. If rxvt-unicode wasn't
572started from a terminal (say, from a menu or by remote shell), then the
573system value of `erase', which corresponds to CERASE in <termios.h>, will
574be used (which may not be the same as your stty setting).
575
576For starting a new rxvt-unicode:
577
578 # use Backspace = ^H
579 $ stty erase ^H
580 $ @@URXVT_NAME@@
581
582 # use Backspace = ^?
583 $ stty erase ^?
584 $ @@URXVT_NAME@@
585
586Toggle with C<ESC [ 36 h> / C<ESC [ 36 l>.
587
588For an existing rxvt-unicode:
589
590 # use Backspace = ^H
591 $ stty erase ^H
592 $ echo -n "^[[36h"
593
594 # use Backspace = ^?
595 $ stty erase ^?
596 $ echo -n "^[[36l"
597
598This helps satisfy some of the Backspace discrepancies that occur, but
599if you use Backspace = C<^H>, make sure that the termcap/terminfo value
600properly reflects that.
601
602The Delete key is a another casualty of the ill-defined Backspace problem.
603To avoid confusion between the Backspace and Delete keys, the Delete
604key has been assigned an escape sequence to match the vt100 for Execute
605(C<ESC [ 3 ~>) and is in the supplied termcap/terminfo.
606
607Some other Backspace problems:
608
609some editors use termcap/terminfo,
610some editors (vim I'm told) expect Backspace = ^H,
611GNU Emacs (and Emacs-like editors) use ^H for help.
612
613Perhaps someday this will all be resolved in a consistent manner.
614
615=head3 I don't like the key-bindings. How do I change them?
616
617There are some compile-time selections available via configure. Unless
618you have run "configure" with the C<--disable-resources> option you can
619use the `keysym' resource to alter the keystrings associated with keysyms.
620
621Here's an example for a URxvt session started using C<@@URXVT_NAME@@ -name URxvt>
622
623 URxvt.keysym.Home: \033[1~
624 URxvt.keysym.End: \033[4~
625 URxvt.keysym.C-apostrophe: \033<C-'>
626 URxvt.keysym.C-slash: \033<C-/>
627 URxvt.keysym.C-semicolon: \033<C-;>
628 URxvt.keysym.C-grave: \033<C-`>
629 URxvt.keysym.C-comma: \033<C-,>
630 URxvt.keysym.C-period: \033<C-.>
631 URxvt.keysym.C-0x60: \033<C-`>
632 URxvt.keysym.C-Tab: \033<C-Tab>
633 URxvt.keysym.C-Return: \033<C-Return>
634 URxvt.keysym.S-Return: \033<S-Return>
635 URxvt.keysym.S-space: \033<S-Space>
636 URxvt.keysym.M-Up: \033<M-Up>
637 URxvt.keysym.M-Down: \033<M-Down>
638 URxvt.keysym.M-Left: \033<M-Left>
639 URxvt.keysym.M-Right: \033<M-Right>
640 URxvt.keysym.M-C-0: list \033<M-C- 0123456789 >
641 URxvt.keysym.M-C-a: list \033<M-C- abcdefghijklmnopqrstuvwxyz >
642 URxvt.keysym.F12: command:\033]701;zh_CN.GBK\007
643
644See some more examples in the documentation for the B<keysym> resource.
645
646=head3 I'm using keyboard model XXX that has extra Prior/Next/Insert keys. How do I make use of them? For example, the Sun Keyboard type 4 has the following map
647
648 KP_Insert == Insert
649 F22 == Print
650 F27 == Home
651 F29 == Prior
652 F33 == End
653 F35 == Next
654
655Rather than have rxvt-unicode try to accommodate all the various possible
656keyboard mappings, it is better to use `xmodmap' to remap the keys as
657required for your particular machine.
658
659
660
661=head2 Terminal Configuration
662
663=head3 Can I see a typical configuration?
664
665The default configuration tries to be xterm-like, which I don't like that
666much, but it's least surprise to regular users.
667
668As a rxvt or rxvt-unicode user, you are practically supposed to invest
669time into customising your terminal. To get you started, here is the
670author's .Xdefaults entries, with comments on what they do. It's certainly
671not I<typical>, but what's typical...
672
673 URxvt.cutchars: "()*,<>[]{}|'
674 URxvt.print-pipe: cat >/tmp/xxx
675
676These are just for testing stuff.
677
678 URxvt.imLocale: ja_JP.UTF-8
679 URxvt.preeditType: OnTheSpot,None
680
681This tells rxvt-unicode to use a special locale when communicating with
682the X Input Method, and also tells it to only use the OnTheSpot pre-edit
683type, which requires the C<xim-onthespot> perl extension but rewards me
684with correct-looking fonts.
685
686 URxvt.perl-lib: /root/lib/urxvt
687 URxvt.perl-ext-common: default,selection-autotransform,selection-pastebin,xim-onthespot,remote-clipboard
688 URxvt.selection.pattern-0: ( at .*? line \\d+)
689 URxvt.selection.pattern-1: ^(/[^:]+):\
690 URxvt.selection-autotransform.0: s/^([^:[:space:]]+):(\\d+):?$/:e \\Q$1\\E\\x0d:$2\\x0d/
691 URxvt.selection-autotransform.1: s/^ at (.*?) line (\\d+)$/:e \\Q$1\\E\\x0d:$2\\x0d/
692
693This is my perl configuration. The first two set the perl library
694directory and also tells urxvt to use a large number of extensions. I
695develop for myself mostly, so I actually use most of the extensions I
696write.
697
698The selection stuff mainly makes the selection perl-error-message aware
699and tells it to convert perl error messages into vi-commands to load the
700relevant file and go tot he error line number.
701
702 URxvt.scrollstyle: plain
703 URxvt.secondaryScroll: true
704
705As the documentation says: plain is the preferred scrollbar for the
706author. The C<secondaryScroll> configures urxvt to scroll in full-screen
707apps, like screen, so lines scrolled out of screen end up in urxvt's
708scrollback buffer.
709
710 URxvt.background: #000000
711 URxvt.foreground: gray90
712 URxvt.color7: gray90
713 URxvt.colorBD: #ffffff
714 URxvt.cursorColor: #e0e080
715 URxvt.throughColor: #8080f0
716 URxvt.highlightColor: #f0f0f0
717
718Some colours. Not sure which ones are being used or even non-defaults, but
719these are in my .Xdefaults. Most notably, they set foreground/background
720to light gray/black, and also make sure that the colour 7 matches the
721default foreground colour.
722
723 URxvt.underlineColor: yellow
724
725Another colour, makes underline lines look different. Sometimes hurts, but
726is mostly a nice effect.
727
728 URxvt.geometry: 154x36
729 URxvt.loginShell: false
730 URxvt.meta: ignore
731 URxvt.utmpInhibit: true
732
733Uh, well, should be mostly self-explanatory. By specifying some defaults
734manually, I can quickly switch them for testing.
735
736 URxvt.saveLines: 8192
737
738A large scrollback buffer is essential. Really.
739
740 URxvt.mapAlert: true
741
742The only case I use it is for my IRC window, which I like to keep
743iconified till people msg me (which beeps).
744
745 URxvt.visualBell: true
746
747The audible bell is often annoying, especially when in a crowd.
748
749 URxvt.insecure: true
750
751Please don't hack my mutt! Ooops...
752
753 URxvt.pastableTabs: false
754
755I once thought this is a great idea.
756
757 urxvt.font: 9x15bold,\
758 -misc-fixed-bold-r-normal--15-140-75-75-c-90-iso10646-1,\
759 -misc-fixed-medium-r-normal--15-140-75-75-c-90-iso10646-1, \
760 [codeset=JISX0208]xft:Kochi Gothic, \
761 xft:Bitstream Vera Sans Mono:autohint=true, \
762 xft:Code2000:antialias=false
763 urxvt.boldFont: -xos4-terminus-bold-r-normal--14-140-72-72-c-80-iso8859-15
764 urxvt.italicFont: xft:Bitstream Vera Sans Mono:italic:autohint=true
765 urxvt.boldItalicFont: xft:Bitstream Vera Sans Mono:bold:italic:autohint=true
766
767I wrote rxvt-unicode to be able to specify fonts exactly. So don't be
768overwhelmed. A special note: the C<9x15bold> mentioned above is actually
769the version from XFree-3.3, as XFree-4 replaced it by a totally different
770font (different glyphs for C<;> and many other harmless characters),
771while the second font is actually the C<9x15bold> from XFree4/XOrg. The
772bold version has less chars than the medium version, so I use it for rare
773characters, too. When editing sources with vim, I use italic for comments
774and other stuff, which looks quite good with Bitstream Vera anti-aliased.
775
776Terminus is a quite bad font (many very wrong glyphs), but for most of my
777purposes, it works, and gives a different look, as my normal (Non-bold)
778font is already bold, and I want to see a difference between bold and
779normal fonts.
780
781Please note that I used the C<urxvt> instance name and not the C<URxvt>
782class name. Thats because I use different configs for different purposes,
783for example, my IRC window is started with C<-name IRC>, and uses these
784defaults:
785
786 IRC*title: IRC
787 IRC*geometry: 87x12+535+542
788 IRC*saveLines: 0
789 IRC*mapAlert: true
790 IRC*font: suxuseuro
791 IRC*boldFont: suxuseuro
792 IRC*colorBD: white
793 IRC*keysym.M-C-1: command:\033]710;suxuseuro\007\033]711;suxuseuro\007
794 IRC*keysym.M-C-2: command:\033]710;9x15bold\007\033]711;9x15bold\007
795
796C<Alt-Shift-1> and C<Alt-Shift-2> switch between two different font
797sizes. C<suxuseuro> allows me to keep an eye (and actually read)
798stuff while keeping a very small window. If somebody pastes something
799complicated (e.g. japanese), I temporarily switch to a larger font.
800
801The above is all in my C<.Xdefaults> (I don't use C<.Xresources> nor
802C<xrdb>). I also have some resources in a separate C<.Xdefaults-hostname>
803file for different hosts, for example, on ym main desktop, I use:
804
805 URxvt.keysym.C-M-q: command:\033[3;5;5t
806 URxvt.keysym.C-M-y: command:\033[3;5;606t
807 URxvt.keysym.C-M-e: command:\033[3;1605;5t
808 URxvt.keysym.C-M-c: command:\033[3;1605;606t
809 URxvt.keysym.C-M-p: perl:test
810
811The first for keysym definitions allow me to quickly bring some windows
812in the layout I like most. Ion users might start laughing but will stop
813immediately when I tell them that I use my own Fvwm2 module for much the
814same effect as Ion provides, and I only very rarely use the above key
815combinations :->
816
817=head3 Why doesn't rxvt-unicode read my resources?
818
819Well, why, indeed? It does, in a way very similar to other X
820applications. Most importantly, this means that if you or your OS loads
821resources into the X display (the right way to do it), rxvt-unicode will
822ignore any resource files in your home directory. It will only read
823F<$HOME/.Xdefaults> when no resources are attached to the display.
824
825If you have or use an F<$HOME/.Xresources> file, chances are that
826resources are loaded into your X-server. In this case, you have to
827re-login after every change (or run F<xrdb -merge $HOME/.Xresources>).
828
829Also consider the form resources have to use:
830
831 URxvt.resource: value
832
833If you want to use another form (there are lots of different ways of
834specifying resources), make sure you understand whether and why it
835works. If unsure, use the form above.
836
837=head3 When I log-in to another system it tells me about missing terminfo data?
838
839The terminal description used by rxvt-unicode is not as widely available
840as that for xterm, or even rxvt (for which the same problem often arises).
841
842The correct solution for this problem is to install the terminfo, this can
843be done like this (with ncurses' infocmp):
844
845 REMOTE=remotesystem.domain
846 infocmp rxvt-unicode | ssh $REMOTE "cat >/tmp/ti && tic /tmp/ti"
847
848... or by installing rxvt-unicode normally on the remote system,
849
850If you cannot or do not want to do this, then you can simply set
851C<TERM=rxvt> or even C<TERM=xterm>, and live with the small number of
852problems arising, which includes wrong keymapping, less and different
853colours and some refresh errors in fullscreen applications. It's a nice
854quick-and-dirty workaround for rare cases, though.
855
856If you always want to do this (and are fine with the consequences) you
857can either recompile rxvt-unicode with the desired TERM value or use a
858resource to set it:
859
860 URxvt.termName: rxvt
861
862If you don't plan to use B<rxvt> (quite common...) you could also replace
863the rxvt terminfo file with the rxvt-unicode one and use C<TERM=rxvt>.
864
865=head3 C<tic> outputs some error when compiling the terminfo entry.
866
867Most likely it's the empty definition for C<enacs=>. Just replace it by
868C<enacs=\E[0@> and try again.
869
870=head3 C<bash>'s readline does not work correctly under @@URXVT_NAME@@.
871
872See next entry.
873
874=head3 I need a termcap file entry.
875
876One reason you might want this is that some distributions or operating
877systems still compile some programs using the long-obsoleted termcap
878library (Fedora Core's bash is one example) and rely on a termcap entry
879for C<rxvt-unicode>.
880
881You could use rxvt's termcap entry with reasonable results in many cases.
882You can also create a termcap entry by using terminfo's infocmp program
883like this:
884
885 infocmp -C rxvt-unicode
886
887Or you could use this termcap entry, generated by the command above:
888

910=head3 Why does C<ls> no longer have coloured output?
911
912The C<ls> in the GNU coreutils unfortunately doesn't use terminfo to
913decide whether a terminal has colour, but uses its own configuration
914file. Needless to say, C<rxvt-unicode> is not in its default file (among
915with most other terminals supporting colour). Either add:
916
917 TERM rxvt-unicode
918
919to C</etc/DIR_COLORS> or simply add:
920
921 alias ls='ls --color=auto'
922
923to your C<.profile> or C<.bashrc>.
924
925=head3 Why doesn't vim/emacs etc. use the 88 colour mode?
926
927See next entry.
928
929=head3 Why doesn't vim/emacs etc. make use of italic?
930
931See next entry.
932
933=head3 Why are the secondary screen-related options not working properly?
934
935Make sure you are using C<TERM=rxvt-unicode>. Some pre-packaged
936distributions (most notably Debian GNU/Linux) break rxvt-unicode
937by setting C<TERM> to C<rxvt>, which doesn't have these extra
938features. Unfortunately, some of these (most notably, again, Debian
939GNU/Linux) furthermore fail to even install the C<rxvt-unicode> terminfo
940file, so you will need to install it on your own (See the question B<When
941I log-in to another system it tells me about missing terminfo data?> on
942how to do this).

945=head2 Encoding / Locale / Input Method Issues
946
947=head3 Rxvt-unicode does not seem to understand the selected encoding?
948
949See next entry.
950
951=head3 Unicode does not seem to work?
952
953If you encounter strange problems like typing an accented character but
954getting two unrelated other characters or similar, or if program output is
955subtly garbled, then you should check your locale settings.
956
957Rxvt-unicode must be started with the same C<LC_CTYPE> setting as the
958programs. Often rxvt-unicode is started in the C<C> locale, while the
959login script running within the rxvt-unicode window changes the locale to
960something else, e.g. C<en_GB.UTF-8>. Needless to say, this is not going to work.
961
962The best thing is to fix your startup environment, as you will likely run
963into other problems. If nothing works you can try this in your .profile.
964
965 printf '\33]701;%s\007' "$LC_CTYPE"
966
967If this doesn't work, then maybe you use a C<LC_CTYPE> specification not
968supported on your systems. Some systems have a C<locale> command which
969displays this (also, C<perl -e0> can be used to check locale settings, as
970it will complain loudly if it cannot set the locale). If it displays something
971like:
972
973 locale: Cannot set LC_CTYPE to default locale: ...
974
975Then the locale you specified is not supported on your system.
976
977If nothing works and you are sure that everything is set correctly then
978you will need to remember a little known fact: Some programs just don't
979support locales :(
980
981=head3 How does rxvt-unicode determine the encoding to use?
982
983See next entry.
984
985=head3 Is there an option to switch encodings?
986
987Unlike some other terminals, rxvt-unicode has no encoding switch, and no
988specific "utf-8" mode, such as xterm. In fact, it doesn't even know about
989UTF-8 or any other encodings with respect to terminal I/O.
990
991The reasons is that there exists a perfectly fine mechanism for selecting
992the encoding, doing I/O and (most important) communicating this to all
993applications so everybody agrees on character properties such as width
994and code number. This mechanism is the I<locale>. Applications not using
995that info will have problems (for example, C<xterm> gets the width of
996characters wrong as it uses its own, locale-independent table under all
997locales).
998
999Rxvt-unicode uses the C<LC_CTYPE> locale category to select encoding. All
1000programs doing the same (that is, most) will automatically agree in the
1001interpretation of characters.
1002
1003Unfortunately, there is no system-independent way to select locales, nor
1004is there a standard on how locale specifiers will look like.
1005
1006On most systems, the content of the C<LC_CTYPE> environment variable
1007contains an arbitrary string which corresponds to an already-installed
1008locale. Common names for locales are C<en_US.UTF-8>, C<de_DE.ISO-8859-15>,
1009C<ja_JP.EUC-JP>, i.e. C<language_country.encoding>, but other forms
1010(i.e. C<de> or C<german>) are also common.
1011
1012Rxvt-unicode ignores all other locale categories, and except for
1013the encoding, ignores country or language-specific settings,
1014i.e. C<de_DE.UTF-8> and C<ja_JP.UTF-8> are the normally same to
1015rxvt-unicode.
1016
1017If you want to use a specific encoding you have to make sure you start
1018rxvt-unicode with the correct C<LC_CTYPE> category.
1019
1020=head3 Can I switch locales at runtime?
1021
1022Yes, using an escape sequence. Try something like this, which sets
1023rxvt-unicode's idea of C<LC_CTYPE>.
1024
1025 printf '\33]701;%s\007' ja_JP.SJIS
1026
1027See also the previous answer.
1028
1029Sometimes this capability is rather handy when you want to work in
1030one locale (e.g. C<de_DE.UTF-8>) but some programs don't support it
1031(e.g. UTF-8). For example, I use this script to start C<xjdic>, which
1032first switches to a locale supported by xjdic and back later:
1033
1034 printf '\33]701;%s\007' ja_JP.SJIS
1035 xjdic -js
1036 printf '\33]701;%s\007' de_DE.UTF-8
1037
1038You can also use xterm's C<luit> program, which usually works fine, except
1039for some locales where character width differs between program- and
1040rxvt-unicode-locales.
1041
1042=head3 I have problems getting my input method working.
1043
1044Try a search engine, as this is slightly different for every input method server.
1045
1046Here is a checklist:
1047
1048=over 4
1049
1050=item - Make sure your locale I<and> the imLocale are supported on your OS.
1051
1052Try C<locale -a> or check the documentation for your OS.
1053
1054=item - Make sure your locale or imLocale matches a locale supported by your XIM.
1055
1056For example, B<kinput2> does not support UTF-8 locales, you should use
1057C<ja_JP.EUC-JP> or equivalent.
1058
1059=item - Make sure your XIM server is actually running.
1060
1061=item - Make sure the C<XMODIFIERS> environment variable is set correctly when I<starting> rxvt-unicode.
1062
1063When you want to use e.g. B<kinput2>, it must be set to
1064C<@im=kinput2>. For B<scim>, use C<@im=SCIM>. You can see what input
1065method servers are running with this command:
1066
1067 xprop -root XIM_SERVERS
1068
1069=item
1070
1071=back
1072
1073=head3 My input method wants <some encoding> but I want UTF-8, what can I do?
1074
1075You can specify separate locales for the input method and the rest of the
1076terminal, using the resource C<imlocale>:
1077
1078 URxvt.imlocale: ja_JP.EUC-JP
1079
1080Now you can start your terminal with C<LC_CTYPE=ja_JP.UTF-8> and still
1081use your input method. Please note, however, that, depending on your Xlib
1082version, you may not be able to input characters outside C<EUC-JP> in a
1083normal way then, as your input method limits you.
1084
1085=head3 Rxvt-unicode crashes when the X Input Method changes or exits.
1086
1087Unfortunately, this is unavoidable, as the XIM protocol is racy by
1088design. Applications can avoid some crashes at the expense of memory
1089leaks, and Input Methods can avoid some crashes by careful ordering at
1090exit time. B<kinput2> (and derived input methods) generally succeeds,
1091while B<SCIM> (or similar input methods) fails. In the end, however,
1092crashes cannot be completely avoided even if both sides cooperate.
1093
1094So the only workaround is not to kill your Input Method Servers.
1095
1096
1097=head2 Operating Systems / Package Maintaining
1098
1099=head3 I am using Debian GNU/Linux and have a problem...
1100
1101The Debian GNU/Linux package of rxvt-unicode in sarge contains large
1102patches that considerably change the behaviour of rxvt-unicode (but
1103unfortunately this notice has been removed). Before reporting a bug to
1104the original rxvt-unicode author please download and install the genuine
1105version (L<http://software.schmorp.de#rxvt-unicode>) and try to reproduce
1106the problem. If you cannot, chances are that the problems are specific to
1107Debian GNU/Linux, in which case it should be reported via the Debian Bug
1108Tracking System (use C<reportbug> to report the bug).
1109
1110For other problems that also affect the Debian package, you can and
1111probably should use the Debian BTS, too, because, after all, it's also a
1112bug in the Debian version and it serves as a reminder for other users that
1113might encounter the same issue.
1114
1115=head3 I am maintaining rxvt-unicode for distribution/OS XXX, any recommendation?
1116
1117You should build one binary with the default options. F<configure>
1118now enables most useful options, and the trend goes to making them
1119runtime-switchable, too, so there is usually no drawback to enabling them,
1120except higher disk and possibly memory usage. The perl interpreter should
1121be enabled, as important functionality (menus, selection, likely more in
1122the future) depends on it.
1123
1124You should not overwrite the C<perl-ext-common> snd C<perl-ext> resources
1125system-wide (except maybe with C<defaults>). This will result in useful
1126behaviour. If your distribution aims at low memory, add an empty
1127C<perl-ext-common> resource to the app-defaults file. This will keep the
1128perl interpreter disabled until the user enables it.
1129
1130If you can/want build more binaries, I recommend building a minimal
1131one with C<--disable-everything> (very useful) and a maximal one with
1132C<--enable-everything> (less useful, it will be very big due to a lot of
1133encodings built-in that increase download times and are rarely used).
1134
1135=head3 I need to make it setuid/setgid to support utmp/ptys on my OS, is this safe?
1136
1137It should be, starting with release 7.1. You are encouraged to properly
1138install urxvt with privileges necessary for your OS now.
1139
1140When rxvt-unicode detects that it runs setuid or setgid, it will fork
1141into a helper process for privileged operations (pty handling on some
1142systems, utmp/wtmp/lastlog handling on others) and drop privileges
1143immediately. This is much safer than most other terminals that keep
1144privileges while running (but is more relevant to urxvt, as it contains
1145things as perl interpreters, which might be "helpful" to attackers).
1146
1147This forking is done as the very first within main(), which is very early
1148and reduces possible bugs to initialisation code run before main(), or
1149things like the dynamic loader of your system, which should result in very
1150little risk.
1151
1152=head3 On Solaris 9, many line-drawing characters are too wide.
1153
1154Seems to be a known bug, read
1155L<http://nixdoc.net/files/forum/about34198.html>. Some people use the
1156following ugly workaround to get non-double-wide-characters working:
1157
1158 #define wcwidth(x) wcwidth(x) > 1 ? 1 : wcwidth(x)
1159
1160=head3 I am on FreeBSD and rxvt-unicode does not seem to work at all.
1161
1162Rxvt-unicode requires the symbol C<__STDC_ISO_10646__> to be defined
1163in your compile environment, or an implementation that implements it,
1164whether it defines the symbol or not. C<__STDC_ISO_10646__> requires that
1165B<wchar_t> is represented as unicode.
1166
1167As you might have guessed, FreeBSD does neither define this symbol nor
1168does it support it. Instead, it uses its own internal representation of
1169B<wchar_t>. This is, of course, completely fine with respect to standards.
1170
1171However, that means rxvt-unicode only works in C<POSIX>, C<ISO-8859-1> and
1172C<UTF-8> locales under FreeBSD (which all use Unicode as B<wchar_t>.
1173
1174C<__STDC_ISO_10646__> is the only sane way to support multi-language
1175apps in an OS, as using a locale-dependent (and non-standardized)
1176representation of B<wchar_t> makes it impossible to convert between
1177B<wchar_t> (as used by X11 and your applications) and any other encoding
1178without implementing OS-specific-wrappers for each and every locale. There
1179simply are no APIs to convert B<wchar_t> into anything except the current
1180locale encoding.
1181
1182Some applications (such as the formidable B<mlterm>) work around this
1183by carrying their own replacement functions for character set handling
1184with them, and either implementing OS-dependent hacks or doing multiple
1185conversions (which is slow and unreliable in case the OS implements
1186encodings slightly different than the terminal emulator).
1187
1188The rxvt-unicode author insists that the right way to fix this is in the
1189system libraries once and for all, instead of forcing every app to carry
1190complete replacements for them :)
1191
1192=head3 I use Solaris 9 and it doesn't compile/work/etc.
1193
1194Try the diff in F<doc/solaris9.patch> as a base. It fixes the worst
1195problems with C<wcwidth> and a compile problem.
1196
1197=head3 How can I use rxvt-unicode under cygwin?
1198
1199rxvt-unicode should compile and run out of the box on cygwin, using
1200the X11 libraries that come with cygwin. libW11 emulation is no
1201longer supported (and makes no sense, either, as it only supported a
1202single font). I recommend starting the X-server in C<-multiwindow> or
1203C<-rootless> mode instead, which will result in similar look&feel as the
1204old libW11 emulation.
1205
1206At the time of this writing, cygwin didn't seem to support any multi-byte
1207encodings (you might try C<LC_CTYPE=C-UTF-8>), so you are likely limited
1208to 8-bit encodings.

760
761B<< The exact syntax used is I<almost> solidified. >>
762In the menus, B<DON'T> try to use menuBar commands that add or remove a
763menuBar.
764
765Note that in all of the commands, the B<< I</path/> >> I<cannot> be
766omitted: use B<./> to specify a menu relative to the current menu.
767
768=head2 Overview of menuBar operation
769
770For the menuBar XTerm escape sequence C<ESC ] 703 ; Pt ST>, the syntax
771of C<Pt> can be used for a variety of tasks:
772
773At the top level is the current menuBar which is a member of a circular
774linked-list of other such menuBars.
775
776The menuBar acts as a parent for the various drop-down menus, which in
777turn, may have labels, separator lines, menuItems and subMenus.
778
779The menuItems are the useful bits: you can use them to mimic keyboard
780input or even to send text or escape sequences back to rxvt.
781
782The menuBar syntax is intended to provide a simple yet robust method of
783constructing and manipulating menus and navigating through the
784menuBars.
785
786The first step is to use the tag B<< [menu:I<name>] >> which creates
787the menuBar called I<name> and allows access. You may now or menus,
788subMenus, and menuItems. Finally, use the tag B<[done]> to set the
789menuBar access as B<readonly> to prevent accidental corruption of the
790menus. To re-access the current menuBar for alterations, use the tag
791B<[menu]>, make the alterations and then use B<[done]>
792

801access the named menuBar for creation or alteration. If a new menuBar
802is created, it is called I<name> (max of 15 chars) and the current
803menuBar is pushed onto the stack
804
805=item B<[menu]>
806
807access the current menuBar for alteration
808
809=item B<< [title:+I<string>] >>
810
811set the current menuBar's title to I<string>, which may contain the
812following format specifiers:
813B<%%> : literal B<%> character
814B<%n> : rxvt name (as per the B<-name> command-line option)
815B<%v> : rxvt version
816
817=item B<[done]>
818
819set menuBar access as B<readonly>.
820End-of-file tag for B<< [read:+I<file>] >> operations.
821
822=item B<< [read:+I<file>] >>
823
824read menu commands directly from I<file> (extension ".menu" will be
825appended if required.) Start reading at a line with B<[menu]> or B<<
826[menu:+I<name> >> and continuing until B<[done]> is encountered.
827
828Blank and comment lines (starting with B<#>) are ignored. Actually,
829since any invalid menu commands are also ignored, almost anything could
830be construed as a comment line, but this may be tightened up in the
831future ... so don't count on it!.
832
833=item B<< [read:+I<file>;+I<name>] >>
834
835The same as B<< [read:+I<file>] >>, but start reading at a line with

941=item B<< I</path/>{item}{rtext} action >>
942

945
946=back
947

951
952B<\a \b \E \e \n \r \t \octal>
953
954=item or in control-character notation:
955
956B<^@, ^A .. ^Z .. ^_, ^?>
957
958=back
959
960To send a string starting with a B<NUL> (B<^@>) character to the
961program, start I<action> with a pair of B<NUL> characters (B<^@^@>),
962the first of which will be stripped off and the balance directed to the
963program. Otherwise if I<action> begins with B<NUL> followed by
964non-+B<NUL> characters, the leading B<NUL> is stripped off and the
965balance is sent back to rxvt.
966
967As a convenience for the many Emacs-type editors, I<action> may start
968with B<M-> (eg, B<M-$> is equivalent to B<\E$>) and a B<CR> will be
969appended if missed from B<M-x> commands.
970
971As a convenience for issuing XTerm B<ESC]> sequences from a menubar (or
972quick arrow), a B<BEL> (B<^G>) will be appended if needed.
973
974=over 4
975
976=item For example,
977
978B<M-xapropos> is equivalent to B<\Exapropos\r>
979

981
982B<\E]703;mona;100> is equivalent to B<\E]703;mona;100\a>
983
984=back
985
986The option B<< {I<right-rtext>} >> will be right-justified. In the
987absence of a specified action, this text will be used as the I<action>
988as well.
989
990=over 4
991
992=item For example,
993
994B</File/{Open}{^X^F}> is equivalent to B</File/{Open}{^X^F} ^X^F>

997
998The left label I<is> necessary, since it's used for matching, but
999implicitly hiding the left label (by using same name for both left and
1000right labels), or explicitly hiding the left label (by preceeding it
1001with a dot), makes it possible to have right-justified text only.

1046
1047The menus also provide a hook for I<quick arrows> to provide easier
1048user access. If nothing has been explicitly set, the default is to
1049emulate the curror keys. The syntax permits each arrow to be altered
1050individually or all four at once without re-entering their common
1051beginning/end text. For example, to explicitly associate cursor actions
1052with the arrows, any of the following forms could be used:
