24=head1 RXVT-UNICODE/URXVT FREQUENTLY ASKED QUESTIONS

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

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<pod2xhtml> (from
131F<Pod::Xhtml>). Then go to the 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 :)

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, please address all transparency related issues to Sasha Vasko at
215sasha@aftercode.net and do not bug the author about it. Also, if you can't
216get it working consider it a rite of passage: ... and you failed.
217
218Here are four ways to get transparency. B<Do> read the manpage and option
219descriptions for the programs mentioned and rxvt-unicode. Really, do it!
220
2211. Use transparent mode:
222
223 Esetroot wallpaper.jpg
224 @@URXVT_NAME@@ -tr -tint red -sh 40
225
226That works. If you think it doesn't, you lack transparency and tinting
227support, or you are unable to read.
228
2292. Use a simple pixmap and emulate pseudo-transparency. This enables you
230to use effects other than tinting and shading: Just shade/tint/whatever
231your picture with gimp or any other tool:
232
233 convert wallpaper.jpg -blur 20x20 -modulate 30 background.jpg
234 @@URXVT_NAME@@ -pixmap "background.jpg;:root"
235
236That works. If you think it doesn't, you lack AfterImage support, or you
237are unable to read.
238
2393. Use an ARGB visual:
240
241 @@URXVT_NAME@@ -depth 32 -fg grey90 -bg rgba:0000/0000/4444/cccc
242
243This requires XFT support, and the support of your X-server. If that
244doesn't work for you, blame Xorg and Keith Packard. ARGB visuals aren't
245there yet, no matter what they claim. Rxvt-Unicode contains the necessary
246bugfixes and workarounds for Xft and Xlib to make it work, but that
247doesn't mean that your WM has the required kludges in place.
248
2494. Use xcompmgr and let it do the job:
250
251 xprop -frame -f _NET_WM_WINDOW_OPACITY 32c \
252 -set _NET_WM_WINDOW_OPACITY 0xc0000000
253
254Then click on a window you want to make transparent. Replace C<0xc0000000>
255by other values to change the degree of opacity. If it doesn't work and
256your server crashes, you got to keep the pieces.
257
258=head3 Why does rxvt-unicode sometimes leave pixel droppings?
259
260Most fonts were not designed for terminal use, which means that character
261size varies a lot. A font that is otherwise fine for terminal use might
262contain some characters that are simply too wide. Rxvt-unicode will avoid
263these characters. For characters that are just "a bit" too wide a special
264"careful" rendering mode is used that redraws adjacent characters.
265
266All of this requires that fonts do not lie about character sizes,
267however: Xft fonts often draw glyphs larger than their acclaimed bounding
268box, and rxvt-unicode has no way of detecting this (the correct way is to
269ask for the character bounding box, which unfortunately is wrong in these
270cases).
271
272It's not clear (to me at least), whether this is a bug in Xft, freetype,
273or the respective font. If you encounter this problem you might try using
274the C<-lsp> option to give the font more height. If that doesn't work, you
275might be forced to use a different font.
276
277All of this is not a problem when using X11 core fonts, as their bounding
278box data is correct.
279
280=head3 How can I keep rxvt-unicode from using reverse video so much?
281
282First of all, make sure you are running with the right terminal settings
283(C<TERM=rxvt-unicode>), which will get rid of most of these effects. Then
284make sure you have specified colours for italic and bold, as otherwise
285rxvt-unicode might use reverse video to simulate the effect:
286
287 URxvt.colorBD: white
288 URxvt.colorIT: green
289
290=head3 Some programs assume totally weird colours (red instead of blue), how can I fix that?
291
292For some unexplainable reason, some rare programs assume a very weird
293colour palette when confronted with a terminal with more than the standard
2948 colours (rxvt-unicode supports 88). The right fix is, of course, to fix
295these programs not to assume non-ISO colours without very good reasons.
296
297In the meantime, you can either edit your C<rxvt-unicode> terminfo
298definition to only claim 8 colour support or use C<TERM=rxvt>, which will
299fix colours but keep you from using other rxvt-unicode features.
300
301=head3 Can I switch the fonts at runtime?
302
303Yes, using an escape sequence. Try something like this, which has the same
304effect as using the C<-fn> switch, and takes effect immediately:
305
306 printf '\33]50;%s\007' "9x15bold,xft:Kochi Gothic"
307
308This is useful if you e.g. work primarily with japanese (and prefer a
309japanese font), but you have to switch to chinese temporarily, where
310japanese fonts would only be in your way.
311
312You can think of this as a kind of manual ISO-2022 switching.
313
314=head3 Why do italic characters look as if clipped?
315
316Many fonts have difficulties with italic characters and hinting. For
317example, the otherwise very nicely hinted font C<xft:Bitstream Vera Sans
318Mono> completely fails in its italic face. A workaround might be to
319enable freetype autohinting, i.e. like this:
320
321 URxvt.italicFont: xft:Bitstream Vera Sans Mono:italic:autohint=true
322 URxvt.boldItalicFont: xft:Bitstream Vera Sans Mono:bold:italic:autohint=true
323
324=head3 Can I speed up Xft rendering somehow?
325
326Yes, the most obvious way to speed it up is to avoid Xft entirely, as
327it is simply slow. If you still want Xft fonts you might try to disable
328antialiasing (by appending C<:antialias=false>), which saves lots of
329memory and also speeds up rendering considerably.
330
331=head3 Rxvt-unicode doesn't seem to anti-alias its fonts, what is wrong?
332
333Rxvt-unicode will use whatever you specify as a font. If it needs to
334fall back to its default font search list it will prefer X11 core
335fonts, because they are small and fast, and then use Xft fonts. It has
336antialiasing disabled for most of them, because the author thinks they
337look best that way.
338
339If you want antialiasing, you have to specify the fonts manually.
340
341=head3 What's with this bold/blink stuff?
342
343If no bold colour is set via C<colorBD:>, bold will invert text using the
344standard foreground colour.
345
346For the standard background colour, blinking will actually make the
347text blink when compiled with C<--enable-blinking>. with standard
348colours. Without C<--enable-blinking>, the blink attribute will be
349ignored.
350
351On ANSI colours, bold/blink attributes are used to set high-intensity
352foreground/background colors.
353
354color0-7 are the low-intensity colors.
355
356color8-15 are the corresponding high-intensity colors.
357
358=head3 I don't like the screen colors. How do I change them?
359
360You can change the screen colors at run-time using F<~/.Xdefaults>
361resources (or as long-options).
362
363Here are values that are supposed to resemble a VGA screen,
364including the murky brown that passes for low-intensity yellow:
365
366 URxvt.color0: #000000
367 URxvt.color1: #A80000
368 URxvt.color2: #00A800
369 URxvt.color3: #A8A800
370 URxvt.color4: #0000A8
371 URxvt.color5: #A800A8
372 URxvt.color6: #00A8A8
373 URxvt.color7: #A8A8A8
374
375 URxvt.color8: #000054
376 URxvt.color9: #FF0054
377 URxvt.color10: #00FF54
378 URxvt.color11: #FFFF54
379 URxvt.color12: #0000FF
380 URxvt.color13: #FF00FF
381 URxvt.color14: #00FFFF
382 URxvt.color15: #FFFFFF
383
384And here is a more complete set of non-standard colors.
385
386 URxvt.cursorColor: #dc74d1
387 URxvt.pointerColor: #dc74d1
388 URxvt.background: #0e0e0e
389 URxvt.foreground: #4ad5e1
390 URxvt.color0: #000000
391 URxvt.color8: #8b8f93
392 URxvt.color1: #dc74d1
393 URxvt.color9: #dc74d1

405They have been described (not by me) as "pretty girly".
406
407=head3 Why do some characters look so much different than others?
408
409See next entry.
410
411=head3 How does rxvt-unicode choose fonts?
412
413Most fonts do not contain the full range of Unicode, which is
414fine. Chances are that the font you (or the admin/package maintainer of
415your system/os) have specified does not cover all the characters you want
416to display.
417
418B<rxvt-unicode> makes a best-effort try at finding a replacement
419font. Often the result is fine, but sometimes the chosen font looks
420bad/ugly/wrong. Some fonts have totally strange characters that don't
421resemble the correct glyph at all, and rxvt-unicode lacks the artificial
422intelligence to detect that a specific glyph is wrong: it has to believe
423the font that the characters it claims to contain indeed look correct.
424
425In that case, select a font of your taste and add it to the font list,
426e.g.:
427
428 @@URXVT_NAME@@ -fn basefont,font2,font3...
429
430When rxvt-unicode sees a character, it will first look at the base
431font. If the base font does not contain the character, it will go to the
432next font, and so on. Specifying your own fonts will also speed up this
433search and use less resources within rxvt-unicode and the X-server.
434
435The only limitation is that none of the fonts may be larger than the base
436font, as the base font defines the terminal character cell size, which
437must be the same due to the way terminals work.
438
439=head3 Why do some chinese characters look so different than others?
440
441This is because there is a difference between script and language --
442rxvt-unicode does not know which language the text that is output is,
443as it only knows the unicode character codes. If rxvt-unicode first
444sees a japanese/chinese character, it might choose a japanese font for
445display. Subsequent japanese characters will use that font. Now, many
446chinese characters aren't represented in japanese fonts, so when the first
447non-japanese character comes up, rxvt-unicode will look for a chinese font
448-- unfortunately at this point, it will still use the japanese font for
449chinese characters that are also in the japanese font.
450
451The workaround is easy: just tag a chinese font at the end of your font
452list (see the previous question). The key is to view the font list as
453a preference list: If you expect more japanese, list a japanese font
454first. If you expect more chinese, put a chinese font first.
455
456In the future it might be possible to switch language preferences at
457runtime (the internal data structure has no problem with using different
458fonts for the same character at the same time, but no interface for this
459has been designed yet).
460
461Until then, you might get away with switching fonts at runtime (see L<Can
462I switch the fonts at runtime?> later in this document).
463
464=head3 How can I make mplayer display video correctly?
465
466We are working on it, in the meantime, as a workaround, use something like:

471=head2 Keyboard, Mouse & User Interaction
472
473=head3 The new selection selects pieces that are too big, how can I select single words?
474
475If you want to select e.g. alphanumeric words, you can use the following
476setting:
477
478 URxvt.selection.pattern-0: ([[:word:]]+)
479
480If you click more than twice, the selection will be extended
481more and more.
482
483To get a selection that is very similar to the old code, try this pattern:
484
485 URxvt.selection.pattern-0: ([^"&'()*,;<=>?@[\\\\]^`{|})]+)
486
487Please also note that the I<LeftClick Shift-LeftClik> combination also
488selects words like the old code.
489
490=head3 I don't like the new selection/popups/hotkeys/perl, how do I change/disable it?
491
492You can disable the perl extension completely by setting the
493B<perl-ext-common> resource to the empty string, which also keeps
494rxvt-unicode from initialising perl, saving memory.
495
496If you only want to disable specific features, you first have to
497identify which perl extension is responsible. For this, read the section
498B<PREPACKAGED EXTENSIONS> in the @@URXVT_NAME@@perl(3) manpage. For
499example, to disable the B<selection-popup> and B<option-popup>, specify
500this B<perl-ext-common> resource:
501
502 URxvt.perl-ext-common: default,-selection-popup,-option-popup
503
504This will keep the default extensions, but disable the two popup
505extensions. Some extensions can also be configured, for example,
506scrollback search mode is triggered by B<M-s>. You can move it to any
507other combination either by setting the B<searchable-scrollback> resource:
508
509 URxvt.searchable-scrollback: CM-s
510
511=head3 The cursor moves when selecting text in the current input line, how do I switch this off?
512
513See next entry.
514
515=head3 During rlogin/ssh/telnet/etc. sessions, clicking near the cursor outputs strange escape sequences, how do I fix this?
516
517These are caused by the C<readline> perl extension. Under normal
518circumstances, it will move your cursor around when you click into the
519line that contains it. It tries hard not to do this at the wrong moment,
520but when running a program that doesn't parse cursor movements or in some
521cases during rlogin sessions, it fails to detect this properly.
522
523You can permanently switch this feature off by disabling the C<readline>
524extension:
525
526 URxvt.perl-ext-common: default,-readline
527
528=head3 My numerical keypad acts weird and generates differing output?
529
530Some Debian GNUL/Linux users seem to have this problem, although no
531specific details were reported so far. It is possible that this is caused
532by the wrong C<TERM> setting, although the details of whether and how
533this can happen are unknown, as C<TERM=rxvt> should offer a compatible
534keymap. See the answer to the previous question, and please report if that
535helped.
536
537=head3 My Compose (Multi_key) key is no longer working.
538
539The most common causes for this are that either your locale is not set
540correctly, or you specified a B<preeditStyle> that is not supported by
541your input method. For example, if you specified B<OverTheSpot> and
542your input method (e.g. the default input method handling Compose keys)
543does not support this (for instance because it is not visual), then
544rxvt-unicode will continue without an input method.
545
546In this case either do not specify a B<preeditStyle> or specify more than
547one pre-edit style, such as B<OverTheSpot,Root,None>.
548
549=head3 I cannot type C<Ctrl-Shift-2> to get an ASCII NUL character due to ISO 14755
550
551Either try C<Ctrl-2> alone (it often is mapped to ASCII NUL even on
552international keyboards) or simply use ISO 14755 support to your
553advantage, typing <Ctrl-Shift-0> to get a ASCII NUL. This works for other
554codes, too, such as C<Ctrl-Shift-1-d> to type the default telnet escape
555character and so on.
556
557=head3 Mouse cut/paste suddenly no longer works.
558
559Make sure that mouse reporting is actually turned off since killing
560some editors prematurely may leave the mouse in mouse report mode. I've
561heard that tcsh may use mouse reporting unless it otherwise specified. A
562quick check is to see if cut/paste works when the Alt or Shift keys are
563depressed.
564
565=head3 What's with the strange Backspace/Delete key behaviour?
566
567Assuming that the physical Backspace key corresponds to the
568Backspace keysym (not likely for Linux ... see the following
569question) there are two standard values that can be used for
570Backspace: C<^H> and C<^?>.
571
572Historically, either value is correct, but rxvt-unicode adopts the debian
573policy of using C<^?> when unsure, because it's the one and only correct
574choice :).
575
576Rxvt-unicode tries to inherit the current stty settings and uses the value
577of `erase' to guess the value for backspace. If rxvt-unicode wasn't
578started from a terminal (say, from a menu or by remote shell), then the
579system value of `erase', which corresponds to CERASE in <termios.h>, will
580be used (which may not be the same as your stty setting).
581
582For starting a new rxvt-unicode:
583
584 # use Backspace = ^H
585 $ stty erase ^H
586 $ @@URXVT_NAME@@
587
588 # use Backspace = ^?
589 $ stty erase ^?
590 $ @@URXVT_NAME@@
591
592Toggle with C<ESC [ 36 h> / C<ESC [ 36 l>.
593
594For an existing rxvt-unicode:
595
596 # use Backspace = ^H
597 $ stty erase ^H
598 $ echo -n "^[[36h"
599
600 # use Backspace = ^?
601 $ stty erase ^?
602 $ echo -n "^[[36l"
603
604This helps satisfy some of the Backspace discrepancies that occur, but
605if you use Backspace = C<^H>, make sure that the termcap/terminfo value
606properly reflects that.
607
608The Delete key is a another casualty of the ill-defined Backspace problem.
609To avoid confusion between the Backspace and Delete keys, the Delete
610key has been assigned an escape sequence to match the vt100 for Execute
611(C<ESC [ 3 ~>) and is in the supplied termcap/terminfo.
612
613Some other Backspace problems:
614
615some editors use termcap/terminfo,
616some editors (vim I'm told) expect Backspace = ^H,
617GNU Emacs (and Emacs-like editors) use ^H for help.
618
619Perhaps someday this will all be resolved in a consistent manner.
620
621=head3 I don't like the key-bindings. How do I change them?
622
623There are some compile-time selections available via configure. Unless
624you have run "configure" with the C<--disable-resources> option you can
625use the `keysym' resource to alter the keystrings associated with keysyms.
626
627Here's an example for a URxvt session started using C<@@URXVT_NAME@@ -name URxvt>
628
629 URxvt.keysym.Home: \033[1~
630 URxvt.keysym.End: \033[4~
631 URxvt.keysym.C-apostrophe: \033<C-'>
632 URxvt.keysym.C-slash: \033<C-/>
633 URxvt.keysym.C-semicolon: \033<C-;>
634 URxvt.keysym.C-grave: \033<C-`>
635 URxvt.keysym.C-comma: \033<C-,>
636 URxvt.keysym.C-period: \033<C-.>
637 URxvt.keysym.C-0x60: \033<C-`>
638 URxvt.keysym.C-Tab: \033<C-Tab>
639 URxvt.keysym.C-Return: \033<C-Return>
640 URxvt.keysym.S-Return: \033<S-Return>
641 URxvt.keysym.S-space: \033<S-Space>
642 URxvt.keysym.M-Up: \033<M-Up>
643 URxvt.keysym.M-Down: \033<M-Down>
644 URxvt.keysym.M-Left: \033<M-Left>
645 URxvt.keysym.M-Right: \033<M-Right>
646 URxvt.keysym.M-C-0: list \033<M-C- 0123456789 >
647 URxvt.keysym.M-C-a: list \033<M-C- abcdefghijklmnopqrstuvwxyz >
648 URxvt.keysym.F12: command:\033]701;zh_CN.GBK\007
649
650See some more examples in the documentation for the B<keysym> resource.
651
652=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
653
654 KP_Insert == Insert
655 F22 == Print
656 F27 == Home
657 F29 == Prior
658 F33 == End
659 F35 == Next
660
661Rather than have rxvt-unicode try to accommodate all the various possible
662keyboard mappings, it is better to use `xmodmap' to remap the keys as
663required for your particular machine.
664
665
666=head2 Terminal Configuration
667
668=head3 Can I see a typical configuration?
669
670The default configuration tries to be xterm-like, which I don't like that
671much, but it's least surprise to regular users.
672
673As a rxvt or rxvt-unicode user, you are practically supposed to invest
674time into customising your terminal. To get you started, here is the
675author's .Xdefaults entries, with comments on what they do. It's certainly
676not I<typical>, but what's typical...
677
678 URxvt.cutchars: "()*,<>[]{}|'
679 URxvt.print-pipe: cat >/tmp/xxx
680
681These are just for testing stuff.
682
683 URxvt.imLocale: ja_JP.UTF-8
684 URxvt.preeditType: OnTheSpot,None
685
686This tells rxvt-unicode to use a special locale when communicating with
687the X Input Method, and also tells it to only use the OnTheSpot pre-edit
688type, which requires the C<xim-onthespot> perl extension but rewards me
689with correct-looking fonts.
690
691 URxvt.perl-lib: /root/lib/urxvt
692 URxvt.perl-ext-common: default,selection-autotransform,selection-pastebin,xim-onthespot,remote-clipboard
693 URxvt.selection.pattern-0: ( at .*? line \\d+)
694 URxvt.selection.pattern-1: ^(/[^:]+):\
695 URxvt.selection-autotransform.0: s/^([^:[:space:]]+):(\\d+):?$/:e \\Q$1\\E\\x0d:$2\\x0d/
696 URxvt.selection-autotransform.1: s/^ at (.*?) line (\\d+)$/:e \\Q$1\\E\\x0d:$2\\x0d/
697
698This is my perl configuration. The first two set the perl library
699directory and also tells urxvt to use a large number of extensions. I
700develop for myself mostly, so I actually use most of the extensions I
701write.
702
703The selection stuff mainly makes the selection perl-error-message aware
704and tells it to convert perl error messages into vi-commands to load the
705relevant file and go tot he error line number.
706
707 URxvt.scrollstyle: plain
708 URxvt.secondaryScroll: true
709
710As the documentation says: plain is the preferred scrollbar for the
711author. The C<secondaryScroll> configures urxvt to scroll in full-screen
712apps, like screen, so lines scrolled out of screen end up in urxvt's
713scrollback buffer.
714
715 URxvt.background: #000000
716 URxvt.foreground: gray90
717 URxvt.color7: gray90
718 URxvt.colorBD: #ffffff
719 URxvt.cursorColor: #e0e080
720 URxvt.throughColor: #8080f0
721 URxvt.highlightColor: #f0f0f0
722
723Some colours. Not sure which ones are being used or even non-defaults, but
724these are in my .Xdefaults. Most notably, they set foreground/background
725to light gray/black, and also make sure that the colour 7 matches the
726default foreground colour.
727
728 URxvt.underlineColor: yellow
729
730Another colour, makes underline lines look different. Sometimes hurts, but
731is mostly a nice effect.
732
733 URxvt.geometry: 154x36
734 URxvt.loginShell: false
735 URxvt.meta: ignore
736 URxvt.utmpInhibit: true
737
738Uh, well, should be mostly self-explanatory. By specifying some defaults
739manually, I can quickly switch them for testing.
740
741 URxvt.saveLines: 8192
742
743A large scrollback buffer is essential. Really.
744
745 URxvt.mapAlert: true
746
747The only case I use it is for my IRC window, which I like to keep
748iconified till people msg me (which beeps).
749
750 URxvt.visualBell: true
751
752The audible bell is often annoying, especially when in a crowd.
753
754 URxvt.insecure: true
755
756Please don't hack my mutt! Ooops...
757
758 URxvt.pastableTabs: false
759
760I once thought this is a great idea.
761
762 urxvt.font: 9x15bold,\
763 -misc-fixed-bold-r-normal--15-140-75-75-c-90-iso10646-1,\
764 -misc-fixed-medium-r-normal--15-140-75-75-c-90-iso10646-1, \
765 [codeset=JISX0208]xft:Kochi Gothic, \
766 xft:Bitstream Vera Sans Mono:autohint=true, \
767 xft:Code2000:antialias=false
768 urxvt.boldFont: -xos4-terminus-bold-r-normal--14-140-72-72-c-80-iso8859-15
769 urxvt.italicFont: xft:Bitstream Vera Sans Mono:italic:autohint=true
770 urxvt.boldItalicFont: xft:Bitstream Vera Sans Mono:bold:italic:autohint=true
771
772I wrote rxvt-unicode to be able to specify fonts exactly. So don't be
773overwhelmed. A special note: the C<9x15bold> mentioned above is actually
774the version from XFree-3.3, as XFree-4 replaced it by a totally different
775font (different glyphs for C<;> and many other harmless characters),
776while the second font is actually the C<9x15bold> from XFree4/XOrg. The
777bold version has less chars than the medium version, so I use it for rare
778characters, too. When editing sources with vim, I use italic for comments
779and other stuff, which looks quite good with Bitstream Vera anti-aliased.
780
781Terminus is a quite bad font (many very wrong glyphs), but for most of my
782purposes, it works, and gives a different look, as my normal (Non-bold)
783font is already bold, and I want to see a difference between bold and
784normal fonts.
785
786Please note that I used the C<urxvt> instance name and not the C<URxvt>
787class name. Thats because I use different configs for different purposes,
788for example, my IRC window is started with C<-name IRC>, and uses these
789defaults:
790
791 IRC*title: IRC
792 IRC*geometry: 87x12+535+542
793 IRC*saveLines: 0
794 IRC*mapAlert: true
795 IRC*font: suxuseuro
796 IRC*boldFont: suxuseuro
797 IRC*colorBD: white
798 IRC*keysym.M-C-1: command:\033]710;suxuseuro\007\033]711;suxuseuro\007
799 IRC*keysym.M-C-2: command:\033]710;9x15bold\007\033]711;9x15bold\007
800
801C<Alt-Shift-1> and C<Alt-Shift-2> switch between two different font
802sizes. C<suxuseuro> allows me to keep an eye (and actually read)
803stuff while keeping a very small window. If somebody pastes something
804complicated (e.g. japanese), I temporarily switch to a larger font.
805
806The above is all in my C<.Xdefaults> (I don't use C<.Xresources> nor
807C<xrdb>). I also have some resources in a separate C<.Xdefaults-hostname>
808file for different hosts, for example, on ym main desktop, I use:
809
810 URxvt.keysym.C-M-q: command:\033[3;5;5t
811 URxvt.keysym.C-M-y: command:\033[3;5;606t
812 URxvt.keysym.C-M-e: command:\033[3;1605;5t
813 URxvt.keysym.C-M-c: command:\033[3;1605;606t
814 URxvt.keysym.C-M-p: perl:test
815
816The first for keysym definitions allow me to quickly bring some windows
817in the layout I like most. Ion users might start laughing but will stop
818immediately when I tell them that I use my own Fvwm2 module for much the
819same effect as Ion provides, and I only very rarely use the above key
820combinations :->
821
822=head3 Why doesn't rxvt-unicode read my resources?
823
824Well, why, indeed? It does, in a way very similar to other X
825applications. Most importantly, this means that if you or your OS loads
826resources into the X display (the right way to do it), rxvt-unicode will
827ignore any resource files in your home directory. It will only read
828F<$HOME/.Xdefaults> when no resources are attached to the display.
829
830If you have or use an F<$HOME/.Xresources> file, chances are that
831resources are loaded into your X-server. In this case, you have to
832re-login after every change (or run F<xrdb -merge $HOME/.Xresources>).
833
834Also consider the form resources have to use:
835
836 URxvt.resource: value
837
838If you want to use another form (there are lots of different ways of
839specifying resources), make sure you understand whether and why it
840works. If unsure, use the form above.
841
842=head3 When I log-in to another system it tells me about missing terminfo data?
843
844The terminal description used by rxvt-unicode is not as widely available
845as that for xterm, or even rxvt (for which the same problem often arises).
846
847The correct solution for this problem is to install the terminfo, this can
848be done like this (with ncurses' infocmp and works as user and admin):
849
850 REMOTE=remotesystem.domain
851 infocmp rxvt-unicode | ssh $REMOTE "mkdir -p .terminfo && cat >/tmp/ti && tic /tmp/ti"
852
853... or by installing rxvt-unicode normally on the remote system,
854
855One some systems you might need to set C<$TERMINFO> to the full path of
856F<$HOME/.terminfo> for this to work.
857
858If you cannot or do not want to do this, then you can simply set
859C<TERM=rxvt> or even C<TERM=xterm>, and live with the small number of
860problems arising, which includes wrong keymapping, less and different
861colours and some refresh errors in fullscreen applications. It's a nice
862quick-and-dirty workaround for rare cases, though.
863
864If you always want to do this (and are fine with the consequences) you
865can either recompile rxvt-unicode with the desired TERM value or use a
866resource to set it:
867
868 URxvt.termName: rxvt
869
870If you don't plan to use B<rxvt> (quite common...) you could also replace
871the rxvt terminfo file with the rxvt-unicode one and use C<TERM=rxvt>.
872
873=head3 C<tic> outputs some error when compiling the terminfo entry.
874
875Most likely it's the empty definition for C<enacs=>. Just replace it by
876C<enacs=\E[0@> and try again.
877
878=head3 C<bash>'s readline does not work correctly under @@URXVT_NAME@@.
879
880See next entry.
881
882=head3 I need a termcap file entry.
883
884One reason you might want this is that some distributions or operating
885systems still compile some programs using the long-obsoleted termcap
886library (Fedora Core's bash is one example) and rely on a termcap entry
887for C<rxvt-unicode>.
888
889You could use rxvt's termcap entry with reasonable results in many cases.
890You can also create a termcap entry by using terminfo's infocmp program
891like this:
892
893 infocmp -C rxvt-unicode
894
895Or you could use this termcap entry, generated by the command above:
896

918=head3 Why does C<ls> no longer have coloured output?
919
920The C<ls> in the GNU coreutils unfortunately doesn't use terminfo to
921decide whether a terminal has colour, but uses its own configuration
922file. Needless to say, C<rxvt-unicode> is not in its default file (among
923with most other terminals supporting colour). Either add:
924

941=head3 Why are the secondary screen-related options not working properly?
942
943Make sure you are using C<TERM=rxvt-unicode>. Some pre-packaged
944distributions (most notably Debian GNU/Linux) break rxvt-unicode
945by setting C<TERM> to C<rxvt>, which doesn't have these extra
946features. Unfortunately, some of these (most notably, again, Debian
947GNU/Linux) furthermore fail to even install the C<rxvt-unicode> terminfo
948file, so you will need to install it on your own (See the question B<When
949I log-in to another system it tells me about missing terminfo data?> on
950how to do this).

953=head2 Encoding / Locale / Input Method Issues
954
955=head3 Rxvt-unicode does not seem to understand the selected encoding?
956
957See next entry.
958
959=head3 Unicode does not seem to work?
960
961If you encounter strange problems like typing an accented character but
962getting two unrelated other characters or similar, or if program output is
963subtly garbled, then you should check your locale settings.
964
965Rxvt-unicode must be started with the same C<LC_CTYPE> setting as the
966programs running in it. Often rxvt-unicode is started in the C<C> locale,
967while the login script running within the rxvt-unicode window changes the
968locale to something else, e.g. C<en_GB.UTF-8>. Needless to say, this is
969not going to work, and is the most common cause for problems.
970
971The best thing is to fix your startup environment, as you will likely run
972into other problems. If nothing works you can try this in your .profile.
973
974 printf '\33]701;%s\007' "$LC_CTYPE" # $LANG or $LC_ALL are worth a try, too
975
976If this doesn't work, then maybe you use a C<LC_CTYPE> specification not
977supported on your systems. Some systems have a C<locale> command which
978displays this (also, C<perl -e0> can be used to check locale settings, as
979it will complain loudly if it cannot set the locale). If it displays something
980like:
981
982 locale: Cannot set LC_CTYPE to default locale: ...
983
984Then the locale you specified is not supported on your system.
985
986If nothing works and you are sure that everything is set correctly then
987you will need to remember a little known fact: Some programs just don't
988support locales :(
989
990=head3 How does rxvt-unicode determine the encoding to use?
991
992See next entry.
993
994=head3 Is there an option to switch encodings?
995
996Unlike some other terminals, rxvt-unicode has no encoding switch, and no
997specific "utf-8" mode, such as xterm. In fact, it doesn't even know about
998UTF-8 or any other encodings with respect to terminal I/O.
999
1000The reasons is that there exists a perfectly fine mechanism for selecting
1001the encoding, doing I/O and (most important) communicating this to all
1002applications so everybody agrees on character properties such as width
1003and code number. This mechanism is the I<locale>. Applications not using
1004that info will have problems (for example, C<xterm> gets the width of
1005characters wrong as it uses its own, locale-independent table under all
1006locales).
1007
1008Rxvt-unicode uses the C<LC_CTYPE> locale category to select encoding. All
1009programs doing the same (that is, most) will automatically agree in the
1010interpretation of characters.
1011
1012Unfortunately, there is no system-independent way to select locales, nor
1013is there a standard on how locale specifiers will look like.
1014
1015On most systems, the content of the C<LC_CTYPE> environment variable
1016contains an arbitrary string which corresponds to an already-installed
1017locale. Common names for locales are C<en_US.UTF-8>, C<de_DE.ISO-8859-15>,
1018C<ja_JP.EUC-JP>, i.e. C<language_country.encoding>, but other forms
1019(i.e. C<de> or C<german>) are also common.
1020
1021Rxvt-unicode ignores all other locale categories, and except for
1022the encoding, ignores country or language-specific settings,
1023i.e. C<de_DE.UTF-8> and C<ja_JP.UTF-8> are the normally same to
1024rxvt-unicode.
1025
1026If you want to use a specific encoding you have to make sure you start
1027rxvt-unicode with the correct C<LC_CTYPE> category.
1028
1029=head3 Can I switch locales at runtime?
1030
1031Yes, using an escape sequence. Try something like this, which sets
1032rxvt-unicode's idea of C<LC_CTYPE>.
1033
1034 printf '\33]701;%s\007' ja_JP.SJIS
1035
1036See also the previous answer.
1037
1038Sometimes this capability is rather handy when you want to work in
1039one locale (e.g. C<de_DE.UTF-8>) but some programs don't support it
1040(e.g. UTF-8). For example, I use this script to start C<xjdic>, which
1041first switches to a locale supported by xjdic and back later:
1042
1043 printf '\33]701;%s\007' ja_JP.SJIS
1044 xjdic -js
1045 printf '\33]701;%s\007' de_DE.UTF-8
1046
1047You can also use xterm's C<luit> program, which usually works fine, except
1048for some locales where character width differs between program- and
1049rxvt-unicode-locales.
1050
1051=head3 I have problems getting my input method working.
1052
1053Try a search engine, as this is slightly different for every input method server.
1054
1055Here is a checklist:
1056
1057=over 4
1058
1059=item - Make sure your locale I<and> the imLocale are supported on your OS.
1060
1061Try C<locale -a> or check the documentation for your OS.
1062
1063=item - Make sure your locale or imLocale matches a locale supported by your XIM.
1064
1065For example, B<kinput2> does not support UTF-8 locales, you should use
1066C<ja_JP.EUC-JP> or equivalent.
1067
1068=item - Make sure your XIM server is actually running.
1069
1070=item - Make sure the C<XMODIFIERS> environment variable is set correctly when I<starting> rxvt-unicode.
1071
1072When you want to use e.g. B<kinput2>, it must be set to
1073C<@im=kinput2>. For B<scim>, use C<@im=SCIM>. You can see what input
1074method servers are running with this command:
1075
1076 xprop -root XIM_SERVERS
1077
1078=item
1079
1080=back
1081
1082=head3 My input method wants <some encoding> but I want UTF-8, what can I do?
1083
1084You can specify separate locales for the input method and the rest of the
1085terminal, using the resource C<imlocale>:
1086
1087 URxvt.imlocale: ja_JP.EUC-JP
1088
1089Now you can start your terminal with C<LC_CTYPE=ja_JP.UTF-8> and still
1090use your input method. Please note, however, that, depending on your Xlib
1091version, you may not be able to input characters outside C<EUC-JP> in a
1092normal way then, as your input method limits you.
1093
1094=head3 Rxvt-unicode crashes when the X Input Method changes or exits.
1095
1096Unfortunately, this is unavoidable, as the XIM protocol is racy by
1097design. Applications can avoid some crashes at the expense of memory
1098leaks, and Input Methods can avoid some crashes by careful ordering at
1099exit time. B<kinput2> (and derived input methods) generally succeeds,
1100while B<SCIM> (or similar input methods) fails. In the end, however,
1101crashes cannot be completely avoided even if both sides cooperate.
1102
1103So the only workaround is not to kill your Input Method Servers.
1104
1105
1106=head2 Operating Systems / Package Maintaining
1107
1108=head3 I am using Debian GNU/Linux and have a problem...
1109
1110The Debian GNU/Linux package of rxvt-unicode in sarge contains large
1111patches that considerably change the behaviour of rxvt-unicode (but
1112unfortunately this notice has been removed). Before reporting a bug to
1113the original rxvt-unicode author please download and install the genuine
1114version (L<http://software.schmorp.de#rxvt-unicode>) and try to reproduce
1115the problem. If you cannot, chances are that the problems are specific to
1116Debian GNU/Linux, in which case it should be reported via the Debian Bug
1117Tracking System (use C<reportbug> to report the bug).
1118
1119For other problems that also affect the Debian package, you can and
1120probably should use the Debian BTS, too, because, after all, it's also a
1121bug in the Debian version and it serves as a reminder for other users that
1122might encounter the same issue.
1123
1124=head3 I am maintaining rxvt-unicode for distribution/OS XXX, any recommendation?
1125
1126You should build one binary with the default options. F<configure>
1127now enables most useful options, and the trend goes to making them
1128runtime-switchable, too, so there is usually no drawback to enabling them,
1129except higher disk and possibly memory usage. The perl interpreter should
1130be enabled, as important functionality (menus, selection, likely more in
1131the future) depends on it.
1132
1133You should not overwrite the C<perl-ext-common> snd C<perl-ext> resources
1134system-wide (except maybe with C<defaults>). This will result in useful
1135behaviour. If your distribution aims at low memory, add an empty
1136C<perl-ext-common> resource to the app-defaults file. This will keep the
1137perl interpreter disabled until the user enables it.
1138
1139If you can/want build more binaries, I recommend building a minimal
1140one with C<--disable-everything> (very useful) and a maximal one with
1141C<--enable-everything> (less useful, it will be very big due to a lot of
1142encodings built-in that increase download times and are rarely used).
1143
1144=head3 I need to make it setuid/setgid to support utmp/ptys on my OS, is this safe?
1145
1146It should be, starting with release 7.1. You are encouraged to properly
1147install urxvt with privileges necessary for your OS now.
1148
1149When rxvt-unicode detects that it runs setuid or setgid, it will fork
1150into a helper process for privileged operations (pty handling on some
1151systems, utmp/wtmp/lastlog handling on others) and drop privileges
1152immediately. This is much safer than most other terminals that keep
1153privileges while running (but is more relevant to urxvt, as it contains
1154things as perl interpreters, which might be "helpful" to attackers).
1155
1156This forking is done as the very first within main(), which is very early
1157and reduces possible bugs to initialisation code run before main(), or
1158things like the dynamic loader of your system, which should result in very
1159little risk.
1160
1161=head3 I am on FreeBSD and rxvt-unicode does not seem to work at all.
1162
1163Rxvt-unicode requires the symbol C<__STDC_ISO_10646__> to be defined
1164in your compile environment, or an implementation that implements it,
1165whether it defines the symbol or not. C<__STDC_ISO_10646__> requires that
1166B<wchar_t> is represented as unicode.
1167
1168As you might have guessed, FreeBSD does neither define this symbol nor
1169does it support it. Instead, it uses its own internal representation of
1170B<wchar_t>. This is, of course, completely fine with respect to standards.
1171
1172However, that means rxvt-unicode only works in C<POSIX>, C<ISO-8859-1> and
1173C<UTF-8> locales under FreeBSD (which all use Unicode as B<wchar_t>.
1174
1175C<__STDC_ISO_10646__> is the only sane way to support multi-language
1176apps in an OS, as using a locale-dependent (and non-standardized)
1177representation of B<wchar_t> makes it impossible to convert between
1178B<wchar_t> (as used by X11 and your applications) and any other encoding
1179without implementing OS-specific-wrappers for each and every locale. There
1180simply are no APIs to convert B<wchar_t> into anything except the current
1181locale encoding.
1182
1183Some applications (such as the formidable B<mlterm>) work around this
1184by carrying their own replacement functions for character set handling
1185with them, and either implementing OS-dependent hacks or doing multiple
1186conversions (which is slow and unreliable in case the OS implements
1187encodings slightly different than the terminal emulator).
1188
1189The rxvt-unicode author insists that the right way to fix this is in the
1190system libraries once and for all, instead of forcing every app to carry
1191complete replacements for them :)
1192
1193=head3 How can I use rxvt-unicode under cygwin?
1194
1195rxvt-unicode should compile and run out of the box on cygwin, using
1196the X11 libraries that come with cygwin. libW11 emulation is no
1197longer supported (and makes no sense, either, as it only supported a
1198single font). I recommend starting the X-server in C<-multiwindow> or
1199C<-rootless> mode instead, which will result in similar look&feel as the
1200old libW11 emulation.
1201
1202At the time of this writing, cygwin didn't seem to support any multi-byte
1203encodings (you might try C<LC_CTYPE=C-UTF-8>), so you are likely limited
1204to 8-bit encodings.
1205
1206=head3 Character widths are not correct.
1207
1208urxvt uses the system wcwidth function to know the information about
1209the width of characters, so on systems with incorrect locale data you
1210will likely get bad results. Two notorious examples are Solaris 9,
1211where single-width characters like U+2514 are reported as double-width,
1212and Darwin 8, where combining chars are reported having width 1.
1213
1214The solution is to upgrade your system or switch to a better one. A
1215possibly working workaround is to use a wcwidth implementation like
1216
1217http://www.cl.cam.ac.uk/~mgk25/ucs/wcwidth.c

789
790B<< The exact syntax used is I<almost> solidified. >>
791In the menus, B<DON'T> try to use menuBar commands that add or remove a
792menuBar.
793
794Note that in all of the commands, the B<< I</path/> >> I<cannot> be
795omitted: use B<./> to specify a menu relative to the current menu.
796
797=head2 Overview of menuBar operation
798
799For the menuBar XTerm escape sequence C<ESC ] 703 ; Pt ST>, the syntax
800of C<Pt> can be used for a variety of tasks:
801
802At the top level is the current menuBar which is a member of a circular
803linked-list of other such menuBars.
804
805The menuBar acts as a parent for the various drop-down menus, which in
806turn, may have labels, separator lines, menuItems and subMenus.
807
808The menuItems are the useful bits: you can use them to mimic keyboard
809input or even to send text or escape sequences back to rxvt.
810
811The menuBar syntax is intended to provide a simple yet robust method of
812constructing and manipulating menus and navigating through the
813menuBars.
814
815The first step is to use the tag B<< [menu:I<name>] >> which creates
816the menuBar called I<name> and allows access. You may now or menus,
817subMenus, and menuItems. Finally, use the tag B<[done]> to set the
818menuBar access as B<readonly> to prevent accidental corruption of the
819menus. To re-access the current menuBar for alterations, use the tag

983=item or in control-character notation:
984
985B<^@, ^A .. ^Z .. ^_, ^?>
986
987=back
988
989To send a string starting with a B<NUL> (B<^@>) character to the
990program, start I<action> with a pair of B<NUL> characters (B<^@^@>),
991the first of which will be stripped off and the balance directed to the
992program. Otherwise if I<action> begins with B<NUL> followed by
993non-+B<NUL> characters, the leading B<NUL> is stripped off and the
994balance is sent back to rxvt.
995
996As a convenience for the many Emacs-type editors, I<action> may start
997with B<M-> (eg, B<M-$> is equivalent to B<\E$>) and a B<CR> will be
998appended if missed from B<M-x> commands.
999
1000As a convenience for issuing XTerm B<ESC]> sequences from a menubar (or
1001quick arrow), a B<BEL> (B<^G>) will be appended if needed.
1002
1003=over 4
1004

1006
1007B<M-xapropos> is equivalent to B<\Exapropos\r>

1014
1015The option B<< {I<right-rtext>} >> will be right-justified. In the

1026
1027The left label I<is> necessary, since it's used for matching, but
1028implicitly hiding the left label (by using same name for both left and
1029right labels), or explicitly hiding the left label (by preceeding it
1030with a dot), makes it possible to have right-justified text only.

1075
1076The menus also provide a hook for I<quick arrows> to provide easier
1077user access. If nothing has been explicitly set, the default is to
1078emulate the curror keys. The syntax permits each arrow to be altered
1079individually or all four at once without re-entering their common
1080beginning/end text. For example, to explicitly associate cursor actions
1081with the arrows, any of the following forms could be used:
