		36
		37	Beginning with version 7.3, there is a perl extension that implements a

		43	URxvt.perl-ext-common: default,tabbed
		44
		45	It will also work fine with tabbing functionality of many window managers
		46	or similar tabbing programs, and its embedding-features allow it to be
		47	embedded into other programs, as witnessed by F<doc/rxvt-tabbed> or
		48	the upcoming C<Gtk2::URxvt> perl module, which features a tabbed urxvt
		49	(murxvt) terminal as an example embedding application.

		70	use 10 Megabytes of memory. With C<--enable-unicode3> it gets worse, as
		71	rxvt-unicode then uses 8 bytes per screen cell.
48		72
		73	=head3 How can I start @@URXVT_NAME@@d in a race-free way?
		74
		75	Try C<@@URXVT_NAME@@d -f -o>, which tells @@URXVT_NAME@@d to open the
		76	display, 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
		80	If 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
		90	This tries to create a new terminal, and if fails with exit status 2,
		91	meaning it couldn't connect to the daemon, it will start the daemon and
		92	re-run the command. Subsequent invocations of the script will re-use the
		93	existing 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
		97	The original rxvt and rxvt-unicode always export the variable "COLORTERM",
		98	so you can check and see if that is set. Note that several programs, JED,
		99	slrn, Midnight Commander automatically check this variable to decide
		100	whether or not to use color.
		101
		102	=head3 How do I set the correct, full IP address for the DISPLAY variable?
		103
		104	If you've compiled rxvt-unicode with DISPLAY_IS_IP and have enabled
		105	insecure mode then it is possible to use the following shell script
		106	snippets to correctly set the display. If your version of rxvt-unicode
		107	wasn't also compiled with ESCZ_ANSWER (as assumed in these snippets) then
		108	the COLORTERM variable can be used to distinguish rxvt-unicode from a
		109	regular xterm.
		110
		111	Courtesy of Chuck Blake <cblake@BBN.COM> with the following shell script
		112	snippets:
		113
		114	# Bourne/Korn/POSIX family of shells:
		115	[ ${TERM:-foo} = foo ] && TERM=xterm # assume an xterm if we don't know
		116	if [ ${TERM:-foo} = xterm ]; then
		117	stty -icanon -echo min 0 time 15 # see if enhanced rxvt or not
		118	echo -n '^[Z'
		119	read term_id
		120	stty icanon echo
		121	if [ ""${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
		129	You need to have a recent version of perl installed as F</usr/bin/perl>,
		130	one that comes with F<pod2man>, F<pod2text> and F<pod2xhtml> (from
		131	F<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
		135	I often get asked about this, and I think, no, they didn't cause extra
		136	bloat. If you compare a minimal rxvt and a minimal urxvt, you can see
		137	that the urxvt binary is larger (due to some encoding tables always being
		138	compiled in), but it actually uses less memory (RSS) after startup. Even
		139	with C<--disable-everything>, this comparison is a bit unfair, as many
		140	features unique to urxvt (locale, encoding conversion, iso14755 etc.) are
		141	already 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
		147	When you C<--enable-everything> (which I<is> unfair, as this involves xft
		148	and full locale/XIM support which are quite bloaty inside libX11 and my
		149	libc), 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
		155	The very large size of the text section is explained by the east-asian
		156	encoding tables, which, if unused, take up disk space but nothing else
		157	and can be compiled out unless you rely on X11 core fonts that use those
		158	encodings. The BSS size comes from the 64k emergency buffer that my c++
		159	compiler allocates (but of course doesn't use unless you are out of
		160	memory). Also, using an xft font instead of a core font immediately adds a
		161	few megabytes of RSS. Xft indeed is responsible for a lot of RSS even when
		162	not used.
		163
		164	Of course, due to every character using two or four bytes instead of one,
		165	a large scrollback buffer will ultimately make rxvt-unicode use more
		166	memory.
		167
		168	Compared to e.g. Eterm (5112k), aterm (3132k) and xterm (4680k), this
		169	still fares rather well. And compared to some monsters like gnome-terminal
		170	(21152k + extra 4204k in separate processes) or konsole (22200k + extra
		171	43180k in daemons that stay around after exit, plus half a minute of
		172	startup time, including the hundreds of warnings it spits out), it fares
		173	extremely well *g*.
		174
		175	=head3 Why C++, isn't that unportable/bloated/uncool?
		176
		177	Is this a question? :) It comes up very often. The simple answer is: I had
		178	to write it, and C++ allowed me to write and maintain it in a fraction
		179	of the time and effort (which is a scarce resource for me). Put even
		180	shorter: It simply wouldn't exist without C++.
		181
		182	My personal stance on this is that C++ is less portable than C, but in
		183	the case of rxvt-unicode this hardly matters, as its portability limits
		184	are defined by things like X11, pseudo terminals, locale support and unix
		185	domain sockets, which are all less portable than C++ itself.
		186
		187	Regarding the bloat, see the above question: It's easy to write programs
		188	in C that use gobs of memory, an certainly possible to write programs in
		189	C++ that don't. C++ also often comes with large libraries, but this is
		190	not necessarily the case with GCC. Here is what rxvt links against on my
		191	system 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
		198	And 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
		206	No large bloated libraries (of course, none were linked in statically),
		207	except 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
		214	First of all, please address all transparency related issues to Sasha Vasko at
		215	sasha@aftercode.net and do not bug the author about it. Also, if you can't
		216	get it working consider it a rite of passage: ... and you failed.
		217
		218	Here are four ways to get transparency. B<Do> read the manpage and option
		219	descriptions for the programs mentioned and rxvt-unicode. Really, do it!
		220
		221	1. Use transparent mode:
		222
		223	Esetroot wallpaper.jpg
		224	@@URXVT_NAME@@ -tr -tint red -sh 40
		225
		226	That works. If you think it doesn't, you lack transparency and tinting
		227	support, or you are unable to read.
		228
		229	2. Use a simple pixmap and emulate pseudo-transparency. This enables you
		230	to use effects other than tinting and shading: Just shade/tint/whatever
		231	your 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
		236	That works. If you think it doesn't, you lack AfterImage support, or you
		237	are unable to read.
		238
		239	3. Use an ARGB visual:
		240
		241	@@URXVT_NAME@@ -depth 32 -fg grey90 -bg rgba:0000/0000/4444/cccc
		242
		243	This requires XFT support, and the support of your X-server. If that
		244	doesn't work for you, blame Xorg and Keith Packard. ARGB visuals aren't
		245	there yet, no matter what they claim. Rxvt-Unicode contains the necessary
		246	bugfixes and workarounds for Xft and Xlib to make it work, but that
		247	doesn't mean that your WM has the required kludges in place.
		248
		249	4. 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
		254	Then click on a window you want to make transparent. Replace C<0xc0000000>
		255	by other values to change the degree of opacity. If it doesn't work and
		256	your server crashes, you got to keep the pieces.
		257
		258	=head3 Why does rxvt-unicode sometimes leave pixel droppings?
		259
		260	Most fonts were not designed for terminal use, which means that character
		261	size varies a lot. A font that is otherwise fine for terminal use might
		262	contain some characters that are simply too wide. Rxvt-unicode will avoid
		263	these characters. For characters that are just "a bit" too wide a special
		264	"careful" rendering mode is used that redraws adjacent characters.
		265
		266	All of this requires that fonts do not lie about character sizes,
		267	however: Xft fonts often draw glyphs larger than their acclaimed bounding
		268	box, and rxvt-unicode has no way of detecting this (the correct way is to
		269	ask for the character bounding box, which unfortunately is wrong in these
		270	cases).
		271
		272	It's not clear (to me at least), whether this is a bug in Xft, freetype,
		273	or the respective font. If you encounter this problem you might try using
		274	the C<-lsp> option to give the font more height. If that doesn't work, you
		275	might be forced to use a different font.
		276
		277	All of this is not a problem when using X11 core fonts, as their bounding
		278	box data is correct.
		279
		280	=head3 How can I keep rxvt-unicode from using reverse video so much?
		281
		282	First 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
		284	make sure you have specified colours for italic and bold, as otherwise
		285	rxvt-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
		292	For some unexplainable reason, some rare programs assume a very weird
		293	colour palette when confronted with a terminal with more than the standard
		294	8 colours (rxvt-unicode supports 88). The right fix is, of course, to fix
		295	these programs not to assume non-ISO colours without very good reasons.
		296
		297	In the meantime, you can either edit your C<rxvt-unicode> terminfo
		298	definition to only claim 8 colour support or use C<TERM=rxvt>, which will
		299	fix colours but keep you from using other rxvt-unicode features.
		300
		301	=head3 Can I switch the fonts at runtime?
		302
		303	Yes, using an escape sequence. Try something like this, which has the same
		304	effect as using the C<-fn> switch, and takes effect immediately:
		305
		306	printf '\33]50;%s\007' "9x15bold,xft:Kochi Gothic"
		307
		308	This is useful if you e.g. work primarily with japanese (and prefer a
		309	japanese font), but you have to switch to chinese temporarily, where
		310	japanese fonts would only be in your way.
		311
		312	You can think of this as a kind of manual ISO-2022 switching.
		313
		314	=head3 Why do italic characters look as if clipped?
		315
		316	Many fonts have difficulties with italic characters and hinting. For
		317	example, the otherwise very nicely hinted font C<xft:Bitstream Vera Sans
		318	Mono> completely fails in its italic face. A workaround might be to
		319	enable 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
		326	Yes, the most obvious way to speed it up is to avoid Xft entirely, as
		327	it is simply slow. If you still want Xft fonts you might try to disable
		328	antialiasing (by appending C<:antialias=false>), which saves lots of
		329	memory and also speeds up rendering considerably.
		330
		331	=head3 Rxvt-unicode doesn't seem to anti-alias its fonts, what is wrong?
		332
		333	Rxvt-unicode will use whatever you specify as a font. If it needs to
		334	fall back to its default font search list it will prefer X11 core
		335	fonts, because they are small and fast, and then use Xft fonts. It has
		336	antialiasing disabled for most of them, because the author thinks they
		337	look best that way.
		338
		339	If you want antialiasing, you have to specify the fonts manually.
		340
		341	=head3 What's with this bold/blink stuff?
		342
		343	If no bold colour is set via C<colorBD:>, bold will invert text using the
		344	standard foreground colour.
		345
		346	For the standard background colour, blinking will actually make
		347	the text blink when compiled with C<--enable-text-blink>. Without
		348	C<--enable-text-blink>, the blink attribute will be ignored.
		349
		350	On ANSI colours, bold/blink attributes are used to set high-intensity
		351	foreground/background colors.
		352
		353	color0-7 are the low-intensity colors.
		354
		355	color8-15 are the corresponding high-intensity colors.
		356
		357	=head3 I don't like the screen colors. How do I change them?
		358
		359	You can change the screen colors at run-time using F<~/.Xdefaults>
		360	resources (or as long-options).
		361
		362	Here are values that are supposed to resemble a VGA screen,
		363	including the murky brown that passes for low-intensity yellow:
		364
		365	URxvt.color0: #000000
		366	URxvt.color1: #A80000
		367	URxvt.color2: #00A800
		368	URxvt.color3: #A8A800
		369	URxvt.color4: #0000A8
		370	URxvt.color5: #A800A8
		371	URxvt.color6: #00A8A8
		372	URxvt.color7: #A8A8A8
		373
		374	URxvt.color8: #000054
		375	URxvt.color9: #FF0054
		376	URxvt.color10: #00FF54
		377	URxvt.color11: #FFFF54
		378	URxvt.color12: #0000FF
		379	URxvt.color13: #FF00FF
		380	URxvt.color14: #00FFFF
		381	URxvt.color15: #FFFFFF
		382
		383	And here is a more complete set of non-standard colors.
		384
		385	URxvt.cursorColor: #dc74d1
		386	URxvt.pointerColor: #dc74d1
		387	URxvt.background: #0e0e0e
		388	URxvt.foreground: #4ad5e1
		389	URxvt.color0: #000000
		390	URxvt.color8: #8b8f93
		391	URxvt.color1: #dc74d1
		392	URxvt.color9: #dc74d1
		393	URxvt.color2: #0eb8c7
		394	URxvt.color10: #0eb8c7
		395	URxvt.color3: #dfe37e
		396	URxvt.color11: #dfe37e
		397	URxvt.color5: #9e88f0
		398	URxvt.color13: #9e88f0
		399	URxvt.color6: #73f7ff
		400	URxvt.color14: #73f7ff
		401	URxvt.color7: #e1dddd
		402	URxvt.color15: #e1dddd
		403
		404	They have been described (not by me) as "pretty girly".
		405
		406	=head3 Why do some characters look so much different than others?
		407
		408	See next entry.
		409
		410	=head3 How does rxvt-unicode choose fonts?
		411
		412	Most fonts do not contain the full range of Unicode, which is
		413	fine. Chances are that the font you (or the admin/package maintainer of
		414	your system/os) have specified does not cover all the characters you want
		415	to display.
		416
		417	B<rxvt-unicode> makes a best-effort try at finding a replacement
		418	font. Often the result is fine, but sometimes the chosen font looks
		419	bad/ugly/wrong. Some fonts have totally strange characters that don't
		420	resemble the correct glyph at all, and rxvt-unicode lacks the artificial
		421	intelligence to detect that a specific glyph is wrong: it has to believe
		422	the font that the characters it claims to contain indeed look correct.
		423
		424	In that case, select a font of your taste and add it to the font list,
		425	e.g.:
		426
		427	@@URXVT_NAME@@ -fn basefont,font2,font3...
		428
		429	When rxvt-unicode sees a character, it will first look at the base
		430	font. If the base font does not contain the character, it will go to the
		431	next font, and so on. Specifying your own fonts will also speed up this
		432	search and use less resources within rxvt-unicode and the X-server.
		433
		434	The only limitation is that none of the fonts may be larger than the base
		435	font, as the base font defines the terminal character cell size, which
		436	must be the same due to the way terminals work.
		437
		438	=head3 Why do some chinese characters look so different than others?
		439
		440	This is because there is a difference between script and language --
		441	rxvt-unicode does not know which language the text that is output is,
		442	as it only knows the unicode character codes. If rxvt-unicode first
		443	sees a japanese/chinese character, it might choose a japanese font for
		444	display. Subsequent japanese characters will use that font. Now, many
		445	chinese characters aren't represented in japanese fonts, so when the first
		446	non-japanese character comes up, rxvt-unicode will look for a chinese font
		447	-- unfortunately at this point, it will still use the japanese font for
		448	chinese characters that are also in the japanese font.
		449
		450	The workaround is easy: just tag a chinese font at the end of your font
		451	list (see the previous question). The key is to view the font list as
		452	a preference list: If you expect more japanese, list a japanese font
		453	first. If you expect more chinese, put a chinese font first.
		454
		455	In the future it might be possible to switch language preferences at
		456	runtime (the internal data structure has no problem with using different
		457	fonts for the same character at the same time, but no interface for this
		458	has been designed yet).
		459
		460	Until then, you might get away with switching fonts at runtime (see L<Can
		461	I switch the fonts at runtime?> later in this document).
		462
		463	=head3 How can I make mplayer display video correctly?
		464
		465	We are working on it, in the meantime, as a workaround, use something like:
		466
		467	@@URXVT_NAME@@ -b 600 -geometry 20x1 -e sh -c 'mplayer -wid $WINDOWID file...'
		468
		469
		470	=head2 Keyboard, Mouse & User Interaction
		471
		472	=head3 The new selection selects pieces that are too big, how can I select single words?
		473
		474	If you want to select e.g. alphanumeric words, you can use the following
		475	setting:
		476
		477	URxvt.selection.pattern-0: ([[:word:]]+)
		478
		479	If you click more than twice, the selection will be extended
		480	more and more.
		481
		482	To get a selection that is very similar to the old code, try this pattern:
		483
		484	URxvt.selection.pattern-0: ([^"&'()*,;<=>?@[\\\\]^`{|})]+)
		485
		486	Please also note that the I<LeftClick Shift-LeftClik> combination also
		487	selects words like the old code.
		488
		489	=head3 I don't like the new selection/popups/hotkeys/perl, how do I change/disable it?
		490
		491	You can disable the perl extension completely by setting the
		492	B<perl-ext-common> resource to the empty string, which also keeps
		493	rxvt-unicode from initialising perl, saving memory.
		494
		495	If you only want to disable specific features, you first have to
		496	identify which perl extension is responsible. For this, read the section
		497	B<PREPACKAGED EXTENSIONS> in the @@URXVT_NAME@@perl(3) manpage. For
		498	example, to disable the B<selection-popup> and B<option-popup>, specify
		499	this B<perl-ext-common> resource:
		500
		501	URxvt.perl-ext-common: default,-selection-popup,-option-popup
		502
		503	This will keep the default extensions, but disable the two popup
		504	extensions. Some extensions can also be configured, for example,
		505	scrollback search mode is triggered by B<M-s>. You can move it to any
		506	other combination either by setting the B<searchable-scrollback> resource:
		507
		508	URxvt.searchable-scrollback: CM-s
		509
		510	=head3 The cursor moves when selecting text in the current input line, how do I switch this off?
		511
		512	See next entry.
		513
		514	=head3 During rlogin/ssh/telnet/etc. sessions, clicking near the cursor outputs strange escape sequences, how do I fix this?
		515
		516	These are caused by the C<readline> perl extension. Under normal
		517	circumstances, it will move your cursor around when you click into the
		518	line that contains it. It tries hard not to do this at the wrong moment,
		519	but when running a program that doesn't parse cursor movements or in some
		520	cases during rlogin sessions, it fails to detect this properly.
		521
		522	You can permanently switch this feature off by disabling the C<readline>
		523	extension:
		524
		525	URxvt.perl-ext-common: default,-readline
		526
		527	=head3 My numerical keypad acts weird and generates differing output?
		528
		529	Some Debian GNUL/Linux users seem to have this problem, although no
		530	specific details were reported so far. It is possible that this is caused
		531	by the wrong C<TERM> setting, although the details of whether and how
		532	this can happen are unknown, as C<TERM=rxvt> should offer a compatible
		533	keymap. See the answer to the previous question, and please report if that
		534	helped.
		535
		536	=head3 My Compose (Multi_key) key is no longer working.
		537
		538	The most common causes for this are that either your locale is not set
		539	correctly, or you specified a B<preeditStyle> that is not supported by
		540	your input method. For example, if you specified B<OverTheSpot> and
		541	your input method (e.g. the default input method handling Compose keys)
		542	does not support this (for instance because it is not visual), then
		543	rxvt-unicode will continue without an input method.
		544
		545	In this case either do not specify a B<preeditStyle> or specify more than
		546	one pre-edit style, such as B<OverTheSpot,Root,None>.
		547
		548	=head3 I cannot type C<Ctrl-Shift-2> to get an ASCII NUL character due to ISO 14755
		549
		550	Either try C<Ctrl-2> alone (it often is mapped to ASCII NUL even on
		551	international keyboards) or simply use ISO 14755 support to your
		552	advantage, typing <Ctrl-Shift-0> to get a ASCII NUL. This works for other
		553	codes, too, such as C<Ctrl-Shift-1-d> to type the default telnet escape
		554	character and so on.
		555
		556	=head3 Mouse cut/paste suddenly no longer works.
		557
		558	Make sure that mouse reporting is actually turned off since killing
		559	some editors prematurely may leave the mouse in mouse report mode. I've
		560	heard that tcsh may use mouse reporting unless it otherwise specified. A
		561	quick check is to see if cut/paste works when the Alt or Shift keys are
		562	depressed.
		563
		564	=head3 What's with the strange Backspace/Delete key behaviour?
		565
		566	Assuming that the physical Backspace key corresponds to the
		567	Backspace keysym (not likely for Linux ... see the following
		568	question) there are two standard values that can be used for
		569	Backspace: C<^H> and C<^?>.
		570
		571	Historically, either value is correct, but rxvt-unicode adopts the debian
		572	policy of using C<^?> when unsure, because it's the one and only correct
		573	choice :).
		574
		575	Rxvt-unicode tries to inherit the current stty settings and uses the value
		576	of `erase' to guess the value for backspace. If rxvt-unicode wasn't
		577	started from a terminal (say, from a menu or by remote shell), then the
		578	system value of `erase', which corresponds to CERASE in <termios.h>, will
		579	be used (which may not be the same as your stty setting).
		580
		581	For starting a new rxvt-unicode:
		582
		583	# use Backspace = ^H
		584	$ stty erase ^H
		585	$ @@URXVT_NAME@@
		586
		587	# use Backspace = ^?
		588	$ stty erase ^?
		589	$ @@URXVT_NAME@@
		590
		591	Toggle with C<ESC [ 36 h> / C<ESC [ 36 l>.
		592
		593	For an existing rxvt-unicode:
		594
		595	# use Backspace = ^H
		596	$ stty erase ^H
		597	$ echo -n "^[[36h"
		598
		599	# use Backspace = ^?
		600	$ stty erase ^?
		601	$ echo -n "^[[36l"
		602
		603	This helps satisfy some of the Backspace discrepancies that occur, but
		604	if you use Backspace = C<^H>, make sure that the termcap/terminfo value
		605	properly reflects that.
		606
		607	The Delete key is a another casualty of the ill-defined Backspace problem.
		608	To avoid confusion between the Backspace and Delete keys, the Delete
		609	key has been assigned an escape sequence to match the vt100 for Execute
		610	(C<ESC [ 3 ~>) and is in the supplied termcap/terminfo.
		611
		612	Some other Backspace problems:
		613
		614	some editors use termcap/terminfo,
		615	some editors (vim I'm told) expect Backspace = ^H,
		616	GNU Emacs (and Emacs-like editors) use ^H for help.
		617
		618	Perhaps someday this will all be resolved in a consistent manner.
		619
		620	=head3 I don't like the key-bindings. How do I change them?
		621
		622	There are some compile-time selections available via configure. Unless
		623	you have run "configure" with the C<--disable-resources> option you can
		624	use the `keysym' resource to alter the keystrings associated with keysyms.
		625
		626	Here's an example for a URxvt session started using C<@@URXVT_NAME@@ -name URxvt>
		627
		628	URxvt.keysym.Home: \033[1~

		648
		649	See some more examples in the documentation for the B<keysym> resource.
		650
		651	=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
		652
		653	KP_Insert == Insert
		654	F22 == Print
		655	F27 == Home
		656	F29 == Prior
		657	F33 == End
		658	F35 == Next
		659
		660	Rather than have rxvt-unicode try to accommodate all the various possible
		661	keyboard mappings, it is better to use `xmodmap' to remap the keys as
		662	required for your particular machine.
		663
		664
		665	=head2 Terminal Configuration
		666
		667	=head3 Can I see a typical configuration?
		668
		669	The default configuration tries to be xterm-like, which I don't like that
		670	much, but it's least surprise to regular users.
		671
		672	As a rxvt or rxvt-unicode user, you are practically supposed to invest
		673	time into customising your terminal. To get you started, here is the
		674	author's .Xdefaults entries, with comments on what they do. It's certainly
		675	not I<typical>, but what's typical...
		676
		677	URxvt.cutchars: "()*,<>[]{}|'
		678	URxvt.print-pipe: cat >/tmp/xxx
		679
		680	These are just for testing stuff.
		681
		682	URxvt.imLocale: ja_JP.UTF-8
		683	URxvt.preeditType: OnTheSpot,None
		684
		685	This tells rxvt-unicode to use a special locale when communicating with
		686	the X Input Method, and also tells it to only use the OnTheSpot pre-edit
		687	type, which requires the C<xim-onthespot> perl extension but rewards me
		688	with correct-looking fonts.
		689
		690	URxvt.perl-lib: /root/lib/urxvt
		691	URxvt.perl-ext-common: default,selection-autotransform,selection-pastebin,xim-onthespot,remote-clipboard
		692	URxvt.selection.pattern-0: ( at .*? line \\d+)
		693	URxvt.selection.pattern-1: ^(/[^:]+):\
		694	URxvt.selection-autotransform.0: s/^([^:[:space:]]+):(\\d+):?$/:e \\Q$1\\E\\x0d:$2\\x0d/
		695	URxvt.selection-autotransform.1: s/^ at (.*?) line (\\d+)$/:e \\Q$1\\E\\x0d:$2\\x0d/
		696
		697	This is my perl configuration. The first two set the perl library
		698	directory and also tells urxvt to use a large number of extensions. I
		699	develop for myself mostly, so I actually use most of the extensions I
		700	write.
		701
		702	The selection stuff mainly makes the selection perl-error-message aware
		703	and tells it to convert perl error messages into vi-commands to load the
		704	relevant file and go tot he error line number.
		705
		706	URxvt.scrollstyle: plain
		707	URxvt.secondaryScroll: true
		708
		709	As the documentation says: plain is the preferred scrollbar for the
		710	author. The C<secondaryScroll> configures urxvt to scroll in full-screen
		711	apps, like screen, so lines scrolled out of screen end up in urxvt's
		712	scrollback buffer.
		713
		714	URxvt.background: #000000
		715	URxvt.foreground: gray90
		716	URxvt.color7: gray90
		717	URxvt.colorBD: #ffffff
		718	URxvt.cursorColor: #e0e080
		719	URxvt.throughColor: #8080f0
		720	URxvt.highlightColor: #f0f0f0
		721
		722	Some colours. Not sure which ones are being used or even non-defaults, but
		723	these are in my .Xdefaults. Most notably, they set foreground/background
		724	to light gray/black, and also make sure that the colour 7 matches the
		725	default foreground colour.
		726
		727	URxvt.underlineColor: yellow
		728
		729	Another colour, makes underline lines look different. Sometimes hurts, but
		730	is mostly a nice effect.
		731
		732	URxvt.geometry: 154x36
		733	URxvt.loginShell: false
		734	URxvt.meta: ignore
		735	URxvt.utmpInhibit: true
		736
		737	Uh, well, should be mostly self-explanatory. By specifying some defaults
		738	manually, I can quickly switch them for testing.
		739
		740	URxvt.saveLines: 8192
		741
		742	A large scrollback buffer is essential. Really.
		743
		744	URxvt.mapAlert: true
		745
		746	The only case I use it is for my IRC window, which I like to keep
		747	iconified till people msg me (which beeps).
		748

		769	urxvt.boldItalicFont: xft:Bitstream Vera Sans Mono:bold:italic:autohint=true
		770
		771	I wrote rxvt-unicode to be able to specify fonts exactly. So don't be
		772	overwhelmed. A special note: the C<9x15bold> mentioned above is actually
		773	the version from XFree-3.3, as XFree-4 replaced it by a totally different
		774	font (different glyphs for C<;> and many other harmless characters),
		775	while the second font is actually the C<9x15bold> from XFree4/XOrg. The
		776	bold version has less chars than the medium version, so I use it for rare
		777	characters, too. When editing sources with vim, I use italic for comments
		778	and other stuff, which looks quite good with Bitstream Vera anti-aliased.
		779
		780	Terminus is a quite bad font (many very wrong glyphs), but for most of my
		781	purposes, it works, and gives a different look, as my normal (Non-bold)
		782	font is already bold, and I want to see a difference between bold and
		783	normal fonts.
		784
		785	Please note that I used the C<urxvt> instance name and not the C<URxvt>
		786	class name. Thats because I use different configs for different purposes,
		787	for example, my IRC window is started with C<-name IRC>, and uses these
		788	defaults:
		789
		790	IRC*title: IRC
		791	IRC*geometry: 87x12+535+542
		792	IRC*saveLines: 0
		793	IRC*mapAlert: true

		796	IRC*colorBD: white
		797	IRC*keysym.M-C-1: command:\033]710;suxuseuro\007\033]711;suxuseuro\007
		798	IRC*keysym.M-C-2: command:\033]710;9x15bold\007\033]711;9x15bold\007
		799
		800	C<Alt-Shift-1> and C<Alt-Shift-2> switch between two different font
		801	sizes. C<suxuseuro> allows me to keep an eye (and actually read)
		802	stuff while keeping a very small window. If somebody pastes something
		803	complicated (e.g. japanese), I temporarily switch to a larger font.
		804
		805	The above is all in my C<.Xdefaults> (I don't use C<.Xresources> nor
		806	C<xrdb>). I also have some resources in a separate C<.Xdefaults-hostname>
		807	file for different hosts, for example, on ym main desktop, I use:
		808
		809	URxvt.keysym.C-M-q: command:\033[3;5;5t
		810	URxvt.keysym.C-M-y: command:\033[3;5;606t

		812	URxvt.keysym.C-M-c: command:\033[3;1605;606t
		813	URxvt.keysym.C-M-p: perl:test
		814
		815	The first for keysym definitions allow me to quickly bring some windows
		816	in the layout I like most. Ion users might start laughing but will stop
		817	immediately when I tell them that I use my own Fvwm2 module for much the
		818	same effect as Ion provides, and I only very rarely use the above key
		819	combinations :->
		820
		821	=head3 Why doesn't rxvt-unicode read my resources?
		822
		823	Well, why, indeed? It does, in a way very similar to other X
		824	applications. Most importantly, this means that if you or your OS loads
		825	resources into the X display (the right way to do it), rxvt-unicode will
		826	ignore any resource files in your home directory. It will only read
		827	F<$HOME/.Xdefaults> when no resources are attached to the display.
		828
		829	If you have or use an F<$HOME/.Xresources> file, chances are that
		830	resources are loaded into your X-server. In this case, you have to
		831	re-login after every change (or run F<xrdb -merge $HOME/.Xresources>).
		832
		833	Also consider the form resources have to use:
		834
		835	URxvt.resource: value
		836
		837	If you want to use another form (there are lots of different ways of
		838	specifying resources), make sure you understand whether and why it
		839	works. If unsure, use the form above.

202	In that case, select a font of your taste and add it to the font list,	999	The reasons is that there exists a perfectly fine mechanism for selecting

210	search and use less resources within rxvt-unicode and the X-server.
211
212	The only limitation is that none of the fonts may be larger than the base

214	must be the same due to the way terminals work.
215
216	=item Why do some chinese characters look so different than others?
217
218	This is because there is a difference between script and language --
219	rxvt-unicode does not know which language the text that is output is,
220	as it only knows the unicode character codes. If rxvt-unicode first
221	sees a japanese/chinese character, it might choose a japanese font for
222	display. Subsequent japanese characters will use that font. Now, many
223	chinese characters aren't represented in japanese fonts, so when the first
224	non-japanese character comes up, rxvt-unicode will look for a chinese font
225	-- unfortunately at this point, it will still use the japanese font for
226	chinese characters that are also in the japanese font.
227
228	The workaround is easy: just tag a chinese font at the end of your font
229	list (see the previous question). The key is to view the font list as
230	a preference list: If you expect more japanese, list a japanese font
231	first. If you expect more chinese, put a chinese font first.
232
233	In the future it might be possible to switch language preferences at
234	runtime (the internal data structure has no problem with using different
235	fonts for the same character at the same time, but no interface for this
236	has been designed yet).
237
238	Until then, you might get away with switching fonts at runtime (see L<Can
239	I switch the fonts at runtime?> later in this document).
240
241	=item Why does rxvt-unicode sometimes leave pixel droppings?
242
243	Most fonts were not designed for terminal use, which means that character
244	size varies a lot. A font that is otherwise fine for terminal use might
245	contain some characters that are simply too wide. Rxvt-unicode will avoid
246	these characters. For characters that are just "a bit" too wide a special
247	"careful" rendering mode is used that redraws adjacent characters.
248
249	All of this requires that fonts do not lie about character sizes,
250	however: Xft fonts often draw glyphs larger than their acclaimed bounding
251	box, and rxvt-unicode has no way of detecting this (the correct way is to
252	ask for the character bounding box, which unfortunately is wrong in these
253	cases).	1005	locales).
254		1006

		1015	contains an arbitrary string which corresponds to an already-installed

		1017	C<ja_JP.EUC-JP>, i.e. C<language_country.encoding>, but other forms
		1018	(i.e. C<de> or C<german>) are also common.
264		1019
265	The most common causes for this are that either your locale is not set	1020	Rxvt-unicode ignores all other locale categories, and except for

		1059
		1060	Try C<locale -a> or check the documentation for your OS.
		1061
		1062	=item - Make sure your locale or imLocale matches a locale supported by your XIM.
		1063
		1064	For example, B<kinput2> does not support UTF-8 locales, you should use
		1065	C<ja_JP.EUC-JP> or equivalent.
		1066
		1067	=item - Make sure your XIM server is actually running.
		1068
		1069	=item - Make sure the C<XMODIFIERS> environment variable is set correctly when I<starting> rxvt-unicode.
		1070
		1071	When you want to use e.g. B<kinput2>, it must be set to
		1072	C<@im=kinput2>. For B<scim>, use C<@im=SCIM>. You can see what input
		1073	method servers are running with this command:
		1074
		1075	xprop -root XIM_SERVERS

		1078
		1079	=back
		1080
		1081	=head3 My input method wants <some encoding> but I want UTF-8, what can I do?
		1082
		1083	You can specify separate locales for the input method and the rest of the
		1084	terminal, using the resource C<imlocale>:
		1085
		1086	URxvt.imlocale: ja_JP.EUC-JP
		1087
		1088	Now you can start your terminal with C<LC_CTYPE=ja_JP.UTF-8> and still
		1089	use your input method. Please note, however, that, depending on your Xlib
		1090	version, you may not be able to input characters outside C<EUC-JP> in a
		1091	normal way then, as your input method limits you.
		1092
		1093	=head3 Rxvt-unicode crashes when the X Input Method changes or exits.
		1094
		1095	Unfortunately, this is unavoidable, as the XIM protocol is racy by
		1096	design. Applications can avoid some crashes at the expense of memory
		1097	leaks, and Input Methods can avoid some crashes by careful ordering at
		1098	exit time. B<kinput2> (and derived input methods) generally succeeds,
		1099	while B<SCIM> (or similar input methods) fails. In the end, however,
		1100	crashes cannot be completely avoided even if both sides cooperate.
		1101

		1125	You should build one binary with the default options. F<configure>
		1126	now enables most useful options, and the trend goes to making them
		1127	runtime-switchable, too, so there is usually no drawback to enabling them,
		1128	except higher disk and possibly memory usage. The perl interpreter should
		1129	be enabled, as important functionality (menus, selection, likely more in
		1130	the future) depends on it.
		1131
		1132	You should not overwrite the C<perl-ext-common> snd C<perl-ext> resources
		1133	system-wide (except maybe with C<defaults>). This will result in useful
		1134	behaviour. If your distribution aims at low memory, add an empty
		1135	C<perl-ext-common> resource to the app-defaults file. This will keep the
		1136	perl interpreter disabled until the user enables it.
		1137
		1138	If you can/want build more binaries, I recommend building a minimal
		1139	one with C<--disable-everything> (very useful) and a maximal one with
		1140	C<--enable-everything> (less useful, it will be very big due to a lot of
		1141	encodings built-in that increase download times and are rarely used).
		1142
		1143	=head3 I need to make it setuid/setgid to support utmp/ptys on my OS, is this safe?
		1144
		1145	It should be, starting with release 7.1. You are encouraged to properly
		1146	install urxvt with privileges necessary for your OS now.
		1147
		1148	When rxvt-unicode detects that it runs setuid or setgid, it will fork
		1149	into a helper process for privileged operations (pty handling on some
		1150	systems, utmp/wtmp/lastlog handling on others) and drop privileges
		1151	immediately. This is much safer than most other terminals that keep
		1152	privileges while running (but is more relevant to urxvt, as it contains
		1153	things as perl interpreters, which might be "helpful" to attackers).
		1154
		1155	This forking is done as the very first within main(), which is very early
		1156	and reduces possible bugs to initialisation code run before main(), or
		1157	things like the dynamic loader of your system, which should result in very
		1158	little risk.

344	The reasons is that there exists a perfectly fine mechanism for selecting	1205	=head3 Character widths are not correct.
345	the encoding, doing I/O and (most important) communicating this to all
346	applications so everybody agrees on character properties such as width
347	and code number. This mechanism is the I<locale>. Applications not using
348	that info will have problems (for example, C<xterm> gets the width of
349	characters wrong as it uses it's own, locale-independent table under all
350	locales).
351		1206
352	Rxvt-unicode uses the C<LC_CTYPE> locale category to select encoding. All	1207	urxvt uses the system wcwidth function to know the information about

359	On most systems, the content of the C<LC_CTYPE> environment variable	1216	http://www.cl.cam.ac.uk/~mgk25/ucs/wcwidth.c
360	contains an arbitrary string which corresponds to an already-installed
361	locale. Common names for locales are C<en_US.UTF-8>, C<de_DE.ISO-8859-15>,
362	C<ja_JP.EUC-JP>, i.e. C<language_country.encoding>, but other forms
363	(i.e. C<de> or C<german>) are also common.
364		1217
365	Rxvt-unicode ignores all other locale categories, and except for
366	the encoding, ignores country or language-specific settings,
367	i.e. C<de_DE.UTF-8> and C<ja_JP.UTF-8> are the normally same to
368	rxvt-unicode.
369
370	If you want to use a specific encoding you have to make sure you start
371	rxvt-unicode with the correct C<LC_CTYPE> category.
372
373	=item Can I switch locales at runtime?
374
375	Yes, using an escape sequence. Try something like this, which sets
376	rxvt-unicode's idea of C<LC_CTYPE>.
377
378	printf '\e]701;%s\007' ja_JP.SJIS
379
380	See also the previous answer.
381
382	Sometimes this capability is rather handy when you want to work in
383	one locale (e.g. C<de_DE.UTF-8>) but some programs don't support it
384	(e.g. UTF-8). For example, I use this script to start C<xjdic>, which
385	first switches to a locale supported by xjdic and back later:
386
387	printf '\e]701;%s\007' ja_JP.SJIS
388	xjdic -js
389	printf '\e]701;%s\007' de_DE.UTF-8
390
391	You can also use xterm's C<luit> program, which usually works fine, except
392	for some locales where character width differs between program- and
393	rxvt-unicode-locales.
394
395	=item Can I switch the fonts at runtime?
396
397	Yes, using an escape sequence. Try something like this, which has the same
398	effect as using the C<-fn> switch, and takes effect immediately:
399
400	printf '\e]50;%s\007' "9x15bold,xft:Kochi Gothic"
401
402	This is useful if you e.g. work primarily with japanese (and prefer a
403	japanese font), but you have to switch to chinese temporarily, where
404	japanese fonts would only be in your way.
405
406	You can think of this as a kind of manual ISO-2022 switching.
407
408	=item Why do italic characters look as if clipped?
409
410	Many fonts have difficulties with italic characters and hinting. For
411	example, the otherwise very nicely hinted font C<xft:Bitstream Vera Sans
412	Mono> completely fails in it's italic face. A workaround might be to
413	enable freetype autohinting, i.e. like this:
414
415	URxvt.italicFont: xft:Bitstream Vera Sans Mono:italic:autohint=true
416	URxvt.boldItalicFont: xft:Bitstream Vera Sans Mono:bold:italic:autohint=true
417
418	=item My input method wants <some encoding> but I want UTF-8, what can I do?
419
420	You can specify separate locales for the input method and the rest of the
421	terminal, using the resource C<imlocale>:
422
423	URxvt*imlocale: ja_JP.EUC-JP
424
425	Now you can start your terminal with C<LC_CTYPE=ja_JP.UTF-8> and still
426	use your input method. Please note, however, that you will not be able to
427	input characters outside C<EUC-JP> in a normal way then, as your input
428	method limits you.
429
430	=item Rxvt-unicode crashes when the X Input Method changes or exits.
431
432	Unfortunately, this is unavoidable, as the XIM protocol is racy by
433	design. Applications can avoid some crashes at the expense of memory
434	leaks, and Input Methods can avoid some crashes by careful ordering at
435	exit time. B<kinput2> (and derived input methods) generally succeeds,
436	while B<SCIM> (or similar input methods) fails. In the end, however,
437	crashes cannot be completely avoided even if both sides cooperate.
438
439	So the only workaround is not to kill your Input Method Servers.
440
441	=item Rxvt-unicode uses gobs of memory, how can I reduce that?
442
443	Rxvt-unicode tries to obey the rule of not charging you for something you
444	don't use. One thing you should try is to configure out all settings that
445	you don't need, for example, Xft support is a resource hog by design,
446	when used. Compiling it out ensures that no Xft font will be loaded
447	accidentally when rxvt-unicode tries to find a font for your characters.
448
449	Also, many people (me included) like large windows and even larger
450	scrollback buffers: Without C<--enable-unicode3>, rxvt-unicode will use
451	6 bytes per screen cell. For a 160x?? window this amounts to almost a
452	kilobyte per line. A scrollback buffer of 10000 lines will then (if full)
453	use 10 Megabytes of memory. With C<--enable-unicode3> it gets worse, as
454	rxvt-unicode then uses 8 bytes per screen cell.
455
456	=item Can I speed up Xft rendering somehow?
457
458	Yes, the most obvious way to speed it up is to avoid Xft entirely, as
459	it is simply slow. If you still want Xft fonts you might try to disable
460	antialiasing (by appending C<:antialiasing=false>), which saves lots of
461	memory and also speeds up rendering considerably.
462
463	=item Rxvt-unicode doesn't seem to anti-alias its fonts, what is wrong?
464
465	Rxvt-unicode will use whatever you specify as a font. If it needs to
466	fall back to it's default font search list it will prefer X11 core
467	fonts, because they are small and fast, and then use Xft fonts. It has
468	antialiasing disabled for most of them, because the author thinks they
469	look best that way.
470
471	If you want antialiasing, you have to specify the fonts manually.
472

480
481	=item What's with this bold/blink stuff?
482
483	If no bold colour is set via C<colorBD:>, bold will invert text using the
484	standard foreground colour.
485
486	For the standard background colour, blinking will actually make the
487	text blink when compiled with C<--enable-blinking>. with standard
488	colours. Without C<--enable-blinking>, the blink attribute will be
489	ignored.
490
491	On ANSI colours, bold/blink attributes are used to set high-intensity
492	foreground/background colors.
493
494	color0-7 are the low-intensity colors.
495
496	color8-15 are the corresponding high-intensity colors.

558
559	Assuming that the physical Backspace key corresponds to the
560	BackSpace keysym (not likely for Linux ... see the following
561	question) there are two standard values that can be used for
562	Backspace: C<^H> and C<^?>.
563
564	Historically, either value is correct, but rxvt-unicode adopts the debian
565	policy of using C<^?> when unsure, because it's the one only only correct
566	choice :).
567
568	Rxvt-unicode tries to inherit the current stty settings and uses the value
569	of `erase' to guess the value for backspace. If rxvt-unicode wasn't
570	started from a terminal (say, from a menu or by remote shell), then the
571	system value of `erase', which corresponds to CERASE in <termios.h>, will
572	be used (which may not be the same as your stty setting).
573
574	For starting a new rxvt-unicode:
575
576	# use Backspace = ^H
577	$ stty erase ^H
578	$ @@RXVT_NAME@@
579
580	# use Backspace = ^?

582	$ @@RXVT_NAME@@
583
584	Toggle with C<ESC [ 36 h> / C<ESC [ 36 l> as documented in @@RXVT_NAME@@(7).
585
586	For an existing rxvt-unicode:
587
588	# use Backspace = ^H
589	$ stty erase ^H
590	$ echo -n "^[[36h"
591
592	# use Backspace = ^?
593	$ stty erase ^?
594	$ echo -n "^[[36l"
595
596	This helps satisfy some of the Backspace discrepancies that occur, but
597	if you use Backspace = C<^H>, make sure that the termcap/terminfo value
598	properly reflects that.
599
600	The Delete key is a another casualty of the ill-defined Backspace problem.
601	To avoid confusion between the Backspace and Delete keys, the Delete
602	key has been assigned an escape sequence to match the vt100 for Execute
603	(C<ESC [ 3 ~>) and is in the supplied termcap/terminfo.
604
605	Some other Backspace problems:
606
607	some editors use termcap/terminfo,
608	some editors (vim I'm told) expect Backspace = ^H,
609	GNU Emacs (and Emacs-like editors) use ^H for help.

1507	B<< The exact syntax used is I<almost> solidified. >>
1508	In the menus, B<DON'T> try to use menuBar commands that add or remove a
1509	menuBar.
1510
1511	Note that in all of the commands, the B<< I</path/> >> I<cannot> be
1512	omitted: use B<./> to specify a menu relative to the current menu.
1513
1514	=head2 Overview of menuBar operation
1515
1516	For the menuBar XTerm escape sequence C<ESC ] 703 ; Pt ST>, the syntax
1517	of C<Pt> can be used for a variety of tasks:
1518
1519	At the top level is the current menuBar which is a member of a circular
1520	linked-list of other such menuBars.
1521
1522	The menuBar acts as a parent for the various drop-down menus, which in
1523	turn, may have labels, separator lines, menuItems and subMenus.
1524
1525	The menuItems are the useful bits: you can use them to mimic keyboard
1526	input or even to send text or escape sequences back to rxvt.
1527
1528	The menuBar syntax is intended to provide a simple yet robust method of
1529	constructing and manipulating menus and navigating through the
1530	menuBars.
1531
1532	The first step is to use the tag B<< [menu:I<name>] >> which creates
1533	the menuBar called I<name> and allows access. You may now or menus,
1534	subMenus, and menuItems. Finally, use the tag B<[done]> to set the
1535	menuBar access as B<readonly> to prevent accidental corruption of the
1536	menus. To re-access the current menuBar for alterations, use the tag
1537	B<[menu]>, make the alterations and then use B<[done]>

1546
1547	access the named menuBar for creation or alteration. If a new menuBar
1548	is created, it is called I<name> (max of 15 chars) and the current
1549	menuBar is pushed onto the stack
1550
1551	=item B<[menu]>
1552
1553	access the current menuBar for alteration
1554
1555	=item B<< [title:+I<string>] >>
1556
1557	set the current menuBar's title to I<string>, which may contain the
1558	following format specifiers:
1559
1560	B<%n> rxvt name (as per the B<-name> command-line option)
1561	B<%v> rxvt version
1562	B<%%> literal B<%> character
1563
1564	=item B<[done]>
1565
1566	set menuBar access as B<readonly>.
1567	End-of-file tag for B<< [read:+I<file>] >> operations.
1568
1569	=item B<< [read:+I<file>] >>
1570
1571	read menu commands directly from I<file> (extension ".menu" will be
1572	appended if required.) Start reading at a line with B<[menu]> or B<<
1573	[menu:+I<name> >> and continuing until B<[done]> is encountered.
1574
1575	Blank and comment lines (starting with B<#>) are ignored. Actually,
1576	since any invalid menu commands are also ignored, almost anything could
1577	be construed as a comment line, but this may be tightened up in the
1578	future ... so don't count on it!.

1707	To send a string starting with a B<NUL> (B<^@>) character to the
1708	program, start I<action> with a pair of B<NUL> characters (B<^@^@>),
1709	the first of which will be stripped off and the balance directed to the
1710	program. Otherwise if I<action> begins with B<NUL> followed by
1711	non-+B<NUL> characters, the leading B<NUL> is stripped off and the
1712	balance is sent back to rxvt.
1713
1714	As a convenience for the many Emacs-type editors, I<action> may start
1715	with B<M-> (eg, B<M-$> is equivalent to B<\E$>) and a B<CR> will be
1716	appended if missed from B<M-x> commands.
1717
1718	As a convenience for issuing XTerm B<ESC ]> sequences from a menubar (or
