		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

		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 the
		347	text blink when compiled with C<--enable-blinking>. with standard
		348	colours. Without C<--enable-blinking>, the blink attribute will be
		349	ignored.
		350
		351	On ANSI colours, bold/blink attributes are used to set high-intensity
		352	foreground/background colors.
		353
		354	color0-7 are the low-intensity colors.
		355
		356	color8-15 are the corresponding high-intensity colors.
		357
		358	=head3 I don't like the screen colors. How do I change them?
		359
		360	You can change the screen colors at run-time using F<~/.Xdefaults>
		361	resources (or as long-options).
		362
		363	Here are values that are supposed to resemble a VGA screen,
		364	including 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
		384	And 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
		394	URxvt.color2: #0eb8c7
		395	URxvt.color10: #0eb8c7
		396	URxvt.color3: #dfe37e
		397	URxvt.color11: #dfe37e
		398	URxvt.color5: #9e88f0
		399	URxvt.color13: #9e88f0
		400	URxvt.color6: #73f7ff
		401	URxvt.color14: #73f7ff
		402	URxvt.color7: #e1dddd
		403	URxvt.color15: #e1dddd
		404
		405	They have been described (not by me) as "pretty girly".
		406
		407	=head3 Why do some characters look so much different than others?
		408
		409	See next entry.
		410
		411	=head3 How does rxvt-unicode choose fonts?
		412
		413	Most fonts do not contain the full range of Unicode, which is
		414	fine. Chances are that the font you (or the admin/package maintainer of
		415	your system/os) have specified does not cover all the characters you want
		416	to display.
		417
		418	B<rxvt-unicode> makes a best-effort try at finding a replacement
		419	font. Often the result is fine, but sometimes the chosen font looks
		420	bad/ugly/wrong. Some fonts have totally strange characters that don't
		421	resemble the correct glyph at all, and rxvt-unicode lacks the artificial
		422	intelligence to detect that a specific glyph is wrong: it has to believe
		423	the font that the characters it claims to contain indeed look correct.
		424
		425	In that case, select a font of your taste and add it to the font list,
		426	e.g.:
		427
		428	@@URXVT_NAME@@ -fn basefont,font2,font3...
		429
		430	When rxvt-unicode sees a character, it will first look at the base
		431	font. If the base font does not contain the character, it will go to the
		432	next font, and so on. Specifying your own fonts will also speed up this
		433	search and use less resources within rxvt-unicode and the X-server.
		434
		435	The only limitation is that none of the fonts may be larger than the base
		436	font, as the base font defines the terminal character cell size, which
		437	must be the same due to the way terminals work.
		438
		439	=head3 Why do some chinese characters look so different than others?
		440
		441	This is because there is a difference between script and language --
		442	rxvt-unicode does not know which language the text that is output is,
		443	as it only knows the unicode character codes. If rxvt-unicode first
		444	sees a japanese/chinese character, it might choose a japanese font for
		445	display. Subsequent japanese characters will use that font. Now, many
		446	chinese characters aren't represented in japanese fonts, so when the first
		447	non-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
		449	chinese characters that are also in the japanese font.
		450
		451	The workaround is easy: just tag a chinese font at the end of your font
		452	list (see the previous question). The key is to view the font list as
		453	a preference list: If you expect more japanese, list a japanese font
		454	first. If you expect more chinese, put a chinese font first.
		455
		456	In the future it might be possible to switch language preferences at
		457	runtime (the internal data structure has no problem with using different
		458	fonts for the same character at the same time, but no interface for this
		459	has been designed yet).
		460
		461	Until then, you might get away with switching fonts at runtime (see L<Can
		462	I switch the fonts at runtime?> later in this document).
		463
		464	=head3 How can I make mplayer display video correctly?
		465
		466	We are working on it, in the meantime, as a workaround, use something like:
		467
		468	@@URXVT_NAME@@ -b 600 -geometry 20x1 -e sh -c 'mplayer -wid $WINDOWID file...'

		470
		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
		475	If you want to select e.g. alphanumeric words, you can use the following
		476	setting:
		477
		478	URxvt.selection.pattern-0: ([[:word:]]+)
		479
		480	If you click more than twice, the selection will be extended
		481	more and more.
		482
		483	To get a selection that is very similar to the old code, try this pattern:
		484
		485	URxvt.selection.pattern-0: ([^"&'()*,;<=>?@[\\\\]^`{|})]+)
		486
		487	Please also note that the I<LeftClick Shift-LeftClik> combination also
		488	selects 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
		492	You can disable the perl extension completely by setting the
		493	B<perl-ext-common> resource to the empty string, which also keeps
		494	rxvt-unicode from initialising perl, saving memory.
		495
		496	If you only want to disable specific features, you first have to
		497	identify which perl extension is responsible. For this, read the section
		498	B<PREPACKAGED EXTENSIONS> in the @@URXVT_NAME@@perl(3) manpage. For
		499	example, to disable the B<selection-popup> and B<option-popup>, specify
		500	this B<perl-ext-common> resource:
		501
		502	URxvt.perl-ext-common: default,-selection-popup,-option-popup
		503
		504	This will keep the default extensions, but disable the two popup
		505	extensions. Some extensions can also be configured, for example,
		506	scrollback search mode is triggered by B<M-s>. You can move it to any
		507	other 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
		513	See 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
		517	These are caused by the C<readline> perl extension. Under normal
		518	circumstances, it will move your cursor around when you click into the
		519	line that contains it. It tries hard not to do this at the wrong moment,
		520	but when running a program that doesn't parse cursor movements or in some
		521	cases during rlogin sessions, it fails to detect this properly.
		522
		523	You can permanently switch this feature off by disabling the C<readline>
		524	extension:
		525
		526	URxvt.perl-ext-common: default,-readline
		527
		528	=head3 My numerical keypad acts weird and generates differing output?
		529
		530	Some Debian GNUL/Linux users seem to have this problem, although no
		531	specific details were reported so far. It is possible that this is caused
		532	by the wrong C<TERM> setting, although the details of whether and how
		533	this can happen are unknown, as C<TERM=rxvt> should offer a compatible
		534	keymap. See the answer to the previous question, and please report if that
		535	helped.
		536
		537	=head3 My Compose (Multi_key) key is no longer working.
		538
		539	The most common causes for this are that either your locale is not set
		540	correctly, or you specified a B<preeditStyle> that is not supported by
		541	your input method. For example, if you specified B<OverTheSpot> and
		542	your input method (e.g. the default input method handling Compose keys)
		543	does not support this (for instance because it is not visual), then
		544	rxvt-unicode will continue without an input method.
		545
		546	In this case either do not specify a B<preeditStyle> or specify more than
		547	one 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
		551	Either try C<Ctrl-2> alone (it often is mapped to ASCII NUL even on
		552	international keyboards) or simply use ISO 14755 support to your
		553	advantage, typing <Ctrl-Shift-0> to get a ASCII NUL. This works for other
		554	codes, too, such as C<Ctrl-Shift-1-d> to type the default telnet escape
		555	character and so on.
		556
		557	=head3 Mouse cut/paste suddenly no longer works.
		558
		559	Make sure that mouse reporting is actually turned off since killing
		560	some editors prematurely may leave the mouse in mouse report mode. I've
		561	heard that tcsh may use mouse reporting unless it otherwise specified. A
		562	quick check is to see if cut/paste works when the Alt or Shift keys are
		563	depressed.
		564
		565	=head3 What's with the strange Backspace/Delete key behaviour?
		566
		567	Assuming that the physical Backspace key corresponds to the
		568	Backspace keysym (not likely for Linux ... see the following
		569	question) there are two standard values that can be used for
		570	Backspace: C<^H> and C<^?>.
		571
		572	Historically, either value is correct, but rxvt-unicode adopts the debian
		573	policy of using C<^?> when unsure, because it's the one and only correct
		574	choice :).
		575
		576	Rxvt-unicode tries to inherit the current stty settings and uses the value
		577	of `erase' to guess the value for backspace. If rxvt-unicode wasn't
		578	started from a terminal (say, from a menu or by remote shell), then the
		579	system value of `erase', which corresponds to CERASE in <termios.h>, will
		580	be used (which may not be the same as your stty setting).
		581
		582	For 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
		592	Toggle with C<ESC [ 36 h> / C<ESC [ 36 l>.
		593
		594	For 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
		604	This helps satisfy some of the Backspace discrepancies that occur, but
		605	if you use Backspace = C<^H>, make sure that the termcap/terminfo value
		606	properly reflects that.
		607
		608	The Delete key is a another casualty of the ill-defined Backspace problem.
		609	To avoid confusion between the Backspace and Delete keys, the Delete
		610	key has been assigned an escape sequence to match the vt100 for Execute
		611	(C<ESC [ 3 ~>) and is in the supplied termcap/terminfo.
		612
		613	Some other Backspace problems:
		614
		615	some editors use termcap/terminfo,
		616	some editors (vim I'm told) expect Backspace = ^H,
		617	GNU Emacs (and Emacs-like editors) use ^H for help.
		618
		619	Perhaps 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
		623	There are some compile-time selections available via configure. Unless
		624	you have run "configure" with the C<--disable-resources> option you can
		625	use the `keysym' resource to alter the keystrings associated with keysyms.
		626
		627	Here's an example for a URxvt session started using C<@@URXVT_NAME@@ -name URxvt>
		628

		649
		650	See 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
		661	Rather than have rxvt-unicode try to accommodate all the various possible
		662	keyboard mappings, it is better to use `xmodmap' to remap the keys as
		663	required for your particular machine.
		664
		665
		666	=head2 Terminal Configuration
		667
		668	=head3 Can I see a typical configuration?
		669
		670	The default configuration tries to be xterm-like, which I don't like that
		671	much, but it's least surprise to regular users.
		672
		673	As a rxvt or rxvt-unicode user, you are practically supposed to invest
		674	time into customising your terminal. To get you started, here is the
		675	author's .Xdefaults entries, with comments on what they do. It's certainly
		676	not I<typical>, but what's typical...
		677
		678	URxvt.cutchars: "()*,<>[]{}|'
		679	URxvt.print-pipe: cat >/tmp/xxx
		680
		681	These are just for testing stuff.
		682
		683	URxvt.imLocale: ja_JP.UTF-8
		684	URxvt.preeditType: OnTheSpot,None
		685
		686	This tells rxvt-unicode to use a special locale when communicating with
		687	the X Input Method, and also tells it to only use the OnTheSpot pre-edit
		688	type, which requires the C<xim-onthespot> perl extension but rewards me
		689	with 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

		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
		698	This is my perl configuration. The first two set the perl library
		699	directory and also tells urxvt to use a large number of extensions. I
		700	develop for myself mostly, so I actually use most of the extensions I
		701	write.
		702
		703	The selection stuff mainly makes the selection perl-error-message aware
		704	and tells it to convert perl error messages into vi-commands to load the
		705	relevant file and go tot he error line number.
		706
		707	URxvt.scrollstyle: plain
		708	URxvt.secondaryScroll: true
		709
		710	As the documentation says: plain is the preferred scrollbar for the
		711	author. The C<secondaryScroll> configures urxvt to scroll in full-screen
		712	apps, like screen, so lines scrolled out of screen end up in urxvt's
		713	scrollback 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
		723	Some colours. Not sure which ones are being used or even non-defaults, but
		724	these are in my .Xdefaults. Most notably, they set foreground/background
		725	to light gray/black, and also make sure that the colour 7 matches the
		726	default foreground colour.
		727
		728	URxvt.underlineColor: yellow
		729
		730	Another colour, makes underline lines look different. Sometimes hurts, but
		731	is mostly a nice effect.
		732
		733	URxvt.geometry: 154x36
		734	URxvt.loginShell: false
		735	URxvt.meta: ignore
		736	URxvt.utmpInhibit: true
		737
		738	Uh, well, should be mostly self-explanatory. By specifying some defaults
		739	manually, I can quickly switch them for testing.
		740
		741	URxvt.saveLines: 8192
		742
		743	A large scrollback buffer is essential. Really.
		744
		745	URxvt.mapAlert: true
		746
		747	The only case I use it is for my IRC window, which I like to keep
		748	iconified till people msg me (which beeps).

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

		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
		801	C<Alt-Shift-1> and C<Alt-Shift-2> switch between two different font
		802	sizes. C<suxuseuro> allows me to keep an eye (and actually read)
		803	stuff while keeping a very small window. If somebody pastes something
		804	complicated (e.g. japanese), I temporarily switch to a larger font.
		805
		806	The above is all in my C<.Xdefaults> (I don't use C<.Xresources> nor
		807	C<xrdb>). I also have some resources in a separate C<.Xdefaults-hostname>
		808	file 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

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

186	=item Why do some characters look so much different than others?
187
188	=item How does rxvt-unicode choose fonts?
189
190	Most fonts do not contain the full range of Unicode, which is
191	fine. Chances are that the font you (or the admin/package maintainer of
192	your system/os) have specified does not cover all the characters you want
193	to display.
194
195	B<rxvt-unicode> makes a best-effort try at finding a replacement
196	font. Often the result is fine, but sometimes the chosen font looks
197	bad/ugly/wrong. Some fonts have totally strange characters that don't
198	resemble the correct glyph at all, and rxvt-unicode lacks the artificial
199	intelligence to detect that a specific glyph is wrong: it has to believe
200	the font that the characters it claims to contain indeed look correct.
201
202	In that case, select a font of your taste and add it to the font list,
203	e.g.:
204
205	@@RXVT_NAME@@ -fn basefont,font2,font3...
206
207	When rxvt-unicode sees a character, it will first look at the base
208	font. If the base font does not contain the character, it will go to the
209	next font, and so on. Specifying your own fonts will also speed up this
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
213	font, as the base font defines the terminal character cell size, which
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).
254
255	It's not clear (to me at least), wether this is a bug in Xft, freetype,
256	or the respective font. If you encounter this problem you might try using
257	the C<-lsp> option to give the font more height. If that doesn't work, you
258	might be forced to use a different font.
259
260	All of this is not a problem when using X11 core fonts, as their bounding
261	box data is correct.
262
263	=item My Compose (Multi_key) key is no longer working.
264
265	The most common causes for this are that either your locale is not set
266	correctly, or you specified a B<preeditStyle> that is not supported by
267	your input method. For example, if you specified B<OverTheSpot> and
268	your input method (e.g. the default input method handling Compose keys)
269	does not support this (for instance because it is not visual), then
270	rxvt-unicode will continue without an input method.
271
272	In this case either do not specify a B<preeditStyle> or specify more than
273	one pre-edit style, such as B<OverTheSpot,Root,None>.
274
275	=item I cannot type C<Ctrl-Shift-2> to get an ASCII NUL character due to ISO 14755
276
277	Either try C<Ctrl-2> alone (it often is mapped to ASCII NUL even on
278	international keyboards) or simply use ISO 14755 support to your
279	advantage, typing <Ctrl-Shift-0> to get a ASCII NUL. This works for other
280	codes, too, such as C<Ctrl-Shift-1-d> to type the default telnet escape
281	character and so on.
282
283	=item How can I keep rxvt-unicode from using reverse video so much?
284
285	First of all, make sure you are running with the right terminal settings
286	(C<TERM=rxvt-unicode>), which will get rid of most of these effects. Then
287	make sure you have specified colours for italic and bold, as otherwise
288	rxvt-unicode might use reverse video to simulate the effect:
289
290	URxvt.colorBD: white
291	URxvt.colorIT: green
292
293	=item Some programs assume totally weird colours (red instead of blue), how can I fix that?
294
295	For some unexplainable reason, some rare programs assume a very weird
296	colour palette when confronted with a terminal with more than the standard
297	8 colours (rxvt-unicode supports 88). The right fix is, of course, to fix
298	these programs not to assume non-ISO colours without very good reasons.
299
300	In the meantime, you can either edit your C<rxvt-unicode> terminfo
301	definition to only claim 8 colour support or use C<TERM=rxvt>, which will
302	fix colours but keep you from using other rxvt-unicode features.
303
304	=item I am on FreeBSD and rxvt-unicode does not seem to work at all.
305
306	Rxvt-unicode requires the symbol C<__STDC_ISO_10646__> to be defined
307	in your compile environment, or an implementation that implements it,
308	wether it defines the symbol or not. C<__STDC_ISO_10646__> requires that
309	B<wchar_t> is represented as unicode.
310
311	As you might have guessed, FreeBSD does neither define this symobl nor
312	does it support it. Instead, it uses it's own internal representation of
313	B<wchar_t>. This is, of course, completely fine with respect to standards.
314
315	However, C<__STDC_ISO_10646__> is the only sane way to support
316	multi-language apps in an OS, as using a locale-dependent (and
317	non-standardized) representation of B<wchar_t> makes it impossible to
318	convert between B<wchar_t> (as used by X11 and your applications) and any
319	other encoding without implementing OS-specific-wrappers for each and
320	every locale. There simply are no APIs to convert B<wchar_t> into anything
321	except the current locale encoding.
322
323	Some applications (such as the formidable B<mlterm>) work around this
324	by carrying their own replacement functions for character set handling
325	with them, and either implementing OS-dependent hacks or doing multiple
326	conversions (which is slow and unreliable in case the OS implements
327	encodings slightly different than the terminal emulator).
328
329	The rxvt-unicode author insists that the right way to fix this is in the
330	system libraries once and for all, instead of forcing every app to carry
331	complete replacements for them :)

554	=item What's with the strange Backspace/Delete key behaviour?
555
556	Assuming that the physical Backspace key corresponds to the
557	BackSpace keysym (not likely for Linux ... see the following
558	question) there are two standard values that can be used for
559	Backspace: C<^H> and C<^?>.
560
561	Historically, either value is correct, but rxvt-unicode adopts the debian
562	policy of using C<^?> when unsure, because it's the one only only correct
563	choice :).
564
565	Rxvt-unicode tries to inherit the current stty settings and uses the value
566	of `erase' to guess the value for backspace. If rxvt-unicode wasn't
567	started from a terminal (say, from a menu or by remote shell), then the
568	system value of `erase', which corresponds to CERASE in <termios.h>, will
569	be used (which may not be the same as your stty setting).
570
571	For starting a new rxvt-unicode:
572
573	# use Backspace = ^H
574	$ stty erase ^H
575	$ @@RXVT_NAME@@
576
577	# use Backspace = ^?

579	$ @@RXVT_NAME@@
580
581	Toggle with C<ESC [ 36 h> / C<ESC [ 36 l> as documented in @@RXVT_NAME@@(7).
582
583	For an existing rxvt-unicode:
584
585	# use Backspace = ^H
586	$ stty erase ^H
587	$ echo -n "^[[36h"
588
589	# use Backspace = ^?
590	$ stty erase ^?
591	$ echo -n "^[[36l"
592
593	This helps satisfy some of the Backspace discrepancies that occur, but
594	if you use Backspace = C<^H>, make sure that the termcap/terminfo value
595	properly reflects that.
596
597	The Delete key is a another casualty of the ill-defined Backspace problem.
598	To avoid confusion between the Backspace and Delete keys, the Delete
599	key has been assigned an escape sequence to match the vt100 for Execute
600	(C<ESC [ 3 ~>) and is in the supplied termcap/terminfo.
601
602	Some other Backspace problems:
603
604	some editors use termcap/terminfo,
605	some editors (vim I'm told) expect Backspace = ^H,

1506	menuBar.

1510
1511	=head2 Overview of menuBar operation
1512
1513	For the menuBar XTerm escape sequence C<ESC ] 703 ; Pt ST>, the syntax
1514	of C<Pt> can be used for a variety of tasks:
1515
1516	At the top level is the current menuBar which is a member of a circular
1517	linked-list of other such menuBars.
1518
1519	The menuBar acts as a parent for the various drop-down menus, which in
1520	turn, may have labels, separator lines, menuItems and subMenus.
1521
1522	The menuItems are the useful bits: you can use them to mimic keyboard
1523	input or even to send text or escape sequences back to rxvt.
1524
1525	The menuBar syntax is intended to provide a simple yet robust method of
1526	constructing and manipulating menus and navigating through the
1527	menuBars.
1528
1529	The first step is to use the tag B<< [menu:I<name>] >> which creates
1530	the menuBar called I<name> and allows access. You may now or menus,
1531	subMenus, and menuItems. Finally, use the tag B<[done]> to set the
1532	menuBar access as B<readonly> to prevent accidental corruption of the
1533	menus. To re-access the current menuBar for alterations, use the tag
1534	B<[menu]>, make the alterations and then use B<[done]>
1535

1544	access the named menuBar for creation or alteration. If a new menuBar
1545	is created, it is called I<name> (max of 15 chars) and the current
1546	menuBar is pushed onto the stack
1547

1549
1550	access the current menuBar for alteration
1551
1552	=item B<< [title:+I<string>] >>
1553
1554	set the current menuBar's title to I<string>, which may contain the
1555	following format specifiers:
1556
1557	B<%n> rxvt name (as per the B<-name> command-line option)
1558	B<%v> rxvt version
1559	B<%%> literal B<%> character
1560

1562
1563	set menuBar access as B<readonly>.
1564	End-of-file tag for B<< [read:+I<file>] >> operations.
1565
1566	=item B<< [read:+I<file>] >>
1567
1568	read menu commands directly from I<file> (extension ".menu" will be
1569	appended if required.) Start reading at a line with B<[menu]> or B<<
1570	[menu:+I<name> >> and continuing until B<[done]> is encountered.
1571
1572	Blank and comment lines (starting with B<#>) are ignored. Actually,
1573	since any invalid menu commands are also ignored, almost anything could
1574	be construed as a comment line, but this may be tightened up in the
1575	future ... so don't count on it!.

1706	the first of which will be stripped off and the balance directed to the

1709	balance is sent back to rxvt.
1710
1711	As a convenience for the many Emacs-type editors, I<action> may start
1712	with B<M-> (eg, B<M-$> is equivalent to B<\E$>) and a B<CR> will be
