		16	=head1 DESCRIPTION
		17
		18	This document contains the FAQ, the RXVT TECHNICAL REFERENCE documenting
		19	all escape sequences, and other background information.
		20
		21	The newest version of this document is
		22	also available on the World Wide Web at
		23	L<http://cvs.schmorp.de/browse/*checkout*/rxvt-unicode/doc/rxvt.7.html>.
		24
		25	=head1 FREQUENTLY ASKED QUESTIONS
		26
		27	=over 4
		28
		29	=item How do I know which rxvt-unicode version I'm using?
		30
		31	The version number is displayed with the usage (-h). Also the escape
		32	sequence C<ESC [ 8 n> sets the window title to the version number.
		33
		34	=item I am using Debian GNU/Linux and have a problem...
		35
		36	The Debian GNU/Linux package of rxvt-unicode in sarge contains large
		37	patches that considerably change the behaviour of rxvt-unicode. Before
		38	reporting a bug to the original rxvt-unicode author please download and
		39	install the genuine version (L<http://software.schmorp.de#rxvt-unicode>)
		40	and try to reproduce the problem. If you cannot, chances are that the
		41	problems are specific to Debian GNU/Linux, in which case it should be
		42	reported via the Debian Bug Tracking System (use C<reportbug> to report
		43	the bug).
		44
		45	For other problems that also affect the Debian package, you can and
		46	probably should use the Debian BTS, too, because, after all, it's also a
		47	bug in the Debian version and it serves as a reminder for other users that
		48	might encounter the same issue.
		49
		50	=item When I log-in to another system it tells me about missing terminfo data?
		51
		52	The terminal description used by rxvt-unicode is not as widely available
		53	as that for xterm, or even rxvt (for which the same problem often arises).
		54
		55	The correct solution for this problem is to install the terminfo, this can
		56	be done like this (with ncurses' infocmp):
		57
		58	REMOTE=remotesystem.domain
		59	infocmp rxvt-unicode | ssh $REMOTE "cat >/tmp/ti && tic /tmp/ti"
		60
		61	... or by installing rxvt-unicode normally on the remote system,
		62
		63	If you cannot or do not want to do this, then you can simply set
		64	C<TERM=rxvt> or even C<TERM=xterm>, and live with the small number of
		65	problems arising, which includes wrong keymapping, less and different
		66	colours and some refresh errors in fullscreen applications. It's a nice
		67	quick-and-dirty workaround for rare cases, though.
		68
		69	If you always want to do this (and are fine with the consequences) you
		70	can either recompile rxvt-unicode with the desired TERM value or use a
		71	resource to set it:
		72
		73	URxvt.termName: rxvt
		74
		75	If you don't plan to use B<rxvt> (quite common...) you could also replace
		76	the rxvt terminfo file with the rxvt-unicode one.
		77
		78	=item C<tic> outputs some error when compiling the terminfo entry.
		79
		80	Most likely it's the empty definition for C<enacs=>. Just replace it by
		81	C<enacs=\E[0@> and try again.
		82
		83	=item C<bash>'s readline does not work correctly under @@RXVT_NAME@@.
		84
		85	=item I need a termcap file entry.
		86
		87	One reason you might want this is that some distributions or operating
		88	systems still compile some programs using the long-obsoleted termcap
		89	library (Fedora Core's bash is one example) and rely on a termcap entry
		90	for C<rxvt-unicode>.
		91
		92	You could use rxvt's termcap entry with resonable results in many cases.
		93	You can also create a termcap entry by using terminfo's infocmp program
		94	like this:
		95
		96	infocmp -C rxvt-unicode
		97
		98	Or you could use this termcap entry, generated by the command above:

		120
		121	=item Why does C<ls> no longer have coloured output?
		122
		123	The C<ls> in the GNU coreutils unfortunately doesn't use terminfo to
		124	decide wether a terminal has colour, but uses it's own configuration
		125	file. Needless to say, C<rxvt-unicode> is not in it's default file (among
		126	with most other terminals supporting colour). Either add:
		127
		128	TERM rxvt-unicode
		129
		130	to C</etc/DIR_COLORS> or simply add:
		131
		132	alias ls='ls --color=auto'
		133
		134	to your C<.profile> or C<.bashrc>.
		135
		136	=item Why doesn't vim/emacs etc. use the 88 colour mode?
		137
		138	=item Why doesn't vim/emacs etc. make use of italic?
		139
		140	=item Why are the secondary screen-related options not working properly?
		141
		142	Make sure you are using C<TERM=rxvt-unicode>. Some pre-packaged
		143	distributions (most notably Debian GNU/Linux) break rxvt-unicode
		144	by setting C<TERM> to C<rxvt>, which doesn't have these extra
		145	features. Unfortunately, some of these (most notably, again, Debian
		146	GNU/Linux) furthermore fail to even install the C<rxvt-unicode> terminfo
		147	file, so you will need to install it on your own (See the question B<When
		148	I log-in to another system it tells me about missing terminfo data?> on
		149	how to do this).
		150
		151	=item My numerical keypad acts weird and generates differing output?
		152
		153	Some Debian GNUL/Linux users seem to have this problem, although no
		154	specific details were reported so far. It is possible that this is caused
		155	by the wrong C<TERM> setting, although the details of wether and how
		156	this can happen are unknown, as C<TERM=rxvt> should offer a compatible
		157	keymap. See the answer to the previous question, and please report if that
		158	helped.
		159
		160	=item Rxvt-unicode does not seem to understand the selected encoding?
		161
		162	=item Unicode does not seem to work?
		163
		164	If you encounter strange problems like typing an accented character but
		165	getting two unrelated other characters or similar, or if program output is
		166	subtly garbled, then you should check your locale settings.
		167
		168	Rxvt-unicode must be started with the same C<LC_CTYPE> setting as the
		169	programs. Often rxvt-unicode is started in the C<C> locale, while the
		170	login script running within the rxvt-unicode window changes the locale to
		171	something else, e.g. C<en_GB.UTF-8>. Needless to say, this is not going to work.
		172
		173	The best thing is to fix your startup environment, as you will likely run
		174	into other problems. If nothing works you can try this in your .profile.
		175
		176	printf '\e]701;%s\007' "$LC_CTYPE"
		177
		178	If this doesn't work, then maybe you use a C<LC_CTYPE> specification not
		179	supported on your systems. Some systems have a C<locale> command which
		180	displays this (also, C<perl -e0> can be used to check locale settings, as
		181	it will complain loudly if it cannot set the locale). If it displays something
		182	like:
		183
		184	locale: Cannot set LC_CTYPE to default locale: ...
		185
		186	Then the locale you specified is not supported on your system.
		187
		188	If nothing works and you are sure that everything is set correctly then
		189	you will need to remember a little known fact: Some programs just don't
		190	support locales :(
		191
		192	=item Why do some characters look so much different than others?
		193
		194	=item How does rxvt-unicode choose fonts?
		195
		196	Most fonts do not contain the full range of Unicode, which is
		197	fine. Chances are that the font you (or the admin/package maintainer of
		198	your system/os) have specified does not cover all the characters you want
		199	to display.
		200
		201	B<rxvt-unicode> makes a best-effort try at finding a replacement
		202	font. Often the result is fine, but sometimes the chosen font looks
		203	bad/ugly/wrong. Some fonts have totally strange characters that don't
		204	resemble the correct glyph at all, and rxvt-unicode lacks the artificial
		205	intelligence to detect that a specific glyph is wrong: it has to believe
		206	the font that the characters it claims to contain indeed look correct.
		207
		208	In that case, select a font of your taste and add it to the font list,
		209	e.g.:
		210
		211	@@RXVT_NAME@@ -fn basefont,font2,font3...
		212
		213	When rxvt-unicode sees a character, it will first look at the base
		214	font. If the base font does not contain the character, it will go to the
		215	next font, and so on. Specifying your own fonts will also speed up this
		216	search and use less resources within rxvt-unicode and the X-server.
		217
		218	The only limitation is that none of the fonts may be larger than the base
		219	font, as the base font defines the terminal character cell size, which
		220	must be the same due to the way terminals work.
		221
		222	=item Why do some chinese characters look so different than others?
		223
		224	This is because there is a difference between script and language --
		225	rxvt-unicode does not know which language the text that is output is,
		226	as it only knows the unicode character codes. If rxvt-unicode first
		227	sees a japanese/chinese character, it might choose a japanese font for
		228	display. Subsequent japanese characters will use that font. Now, many
		229	chinese characters aren't represented in japanese fonts, so when the first
		230	non-japanese character comes up, rxvt-unicode will look for a chinese font
		231	-- unfortunately at this point, it will still use the japanese font for
		232	chinese characters that are also in the japanese font.
		233
		234	The workaround is easy: just tag a chinese font at the end of your font
		235	list (see the previous question). The key is to view the font list as
		236	a preference list: If you expect more japanese, list a japanese font
		237	first. If you expect more chinese, put a chinese font first.
		238
		239	In the future it might be possible to switch language preferences at
		240	runtime (the internal data structure has no problem with using different
		241	fonts for the same character at the same time, but no interface for this
		242	has been designed yet).
		243
		244	Until then, you might get away with switching fonts at runtime (see L<Can
		245	I switch the fonts at runtime?> later in this document).
		246
		247	=item Why does rxvt-unicode sometimes leave pixel droppings?
		248
		249	Most fonts were not designed for terminal use, which means that character
		250	size varies a lot. A font that is otherwise fine for terminal use might
		251	contain some characters that are simply too wide. Rxvt-unicode will avoid
		252	these characters. For characters that are just "a bit" too wide a special
		253	"careful" rendering mode is used that redraws adjacent characters.
		254
		255	All of this requires that fonts do not lie about character sizes,
		256	however: Xft fonts often draw glyphs larger than their acclaimed bounding
		257	box, and rxvt-unicode has no way of detecting this (the correct way is to
		258	ask for the character bounding box, which unfortunately is wrong in these
		259	cases).
		260
		261	It's not clear (to me at least), wether this is a bug in Xft, freetype,
		262	or the respective font. If you encounter this problem you might try using
		263	the C<-lsp> option to give the font more height. If that doesn't work, you
		264	might be forced to use a different font.
		265
		266	All of this is not a problem when using X11 core fonts, as their bounding
		267	box data is correct.
		268
		269	=item On Solaris 9, many line-drawing characters are too wide.
		270
		271	Seems to be a known bug, read
		272	L<http://nixdoc.net/files/forum/about34198.html>. Some people use the
		273	following ugly workaround to get non-double-wide-characters working:
		274
		275	#define wcwidth(x) wcwidth(x) > 1 ? 1 : wcwidth(x)
		276
		277	=item My Compose (Multi_key) key is no longer working.
		278
		279	The most common causes for this are that either your locale is not set
		280	correctly, or you specified a B<preeditStyle> that is not supported by
		281	your input method. For example, if you specified B<OverTheSpot> and
		282	your input method (e.g. the default input method handling Compose keys)
		283	does not support this (for instance because it is not visual), then
		284	rxvt-unicode will continue without an input method.
		285
		286	In this case either do not specify a B<preeditStyle> or specify more than
		287	one pre-edit style, such as B<OverTheSpot,Root,None>.
		288
		289	=item I cannot type C<Ctrl-Shift-2> to get an ASCII NUL character due to ISO 14755
		290
		291	Either try C<Ctrl-2> alone (it often is mapped to ASCII NUL even on
		292	international keyboards) or simply use ISO 14755 support to your
		293	advantage, typing <Ctrl-Shift-0> to get a ASCII NUL. This works for other
		294	codes, too, such as C<Ctrl-Shift-1-d> to type the default telnet escape
		295	character and so on.
		296
		297	=item How can I keep rxvt-unicode from using reverse video so much?
		298
		299	First of all, make sure you are running with the right terminal settings
		300	(C<TERM=rxvt-unicode>), which will get rid of most of these effects. Then
		301	make sure you have specified colours for italic and bold, as otherwise
		302	rxvt-unicode might use reverse video to simulate the effect:
		303
		304	URxvt.colorBD: white
		305	URxvt.colorIT: green
		306
		307	=item Some programs assume totally weird colours (red instead of blue), how can I fix that?
		308
		309	For some unexplainable reason, some rare programs assume a very weird
		310	colour palette when confronted with a terminal with more than the standard
		311	8 colours (rxvt-unicode supports 88). The right fix is, of course, to fix
		312	these programs not to assume non-ISO colours without very good reasons.
		313
		314	In the meantime, you can either edit your C<rxvt-unicode> terminfo
		315	definition to only claim 8 colour support or use C<TERM=rxvt>, which will
		316	fix colours but keep you from using other rxvt-unicode features.
		317
		318	=item I am on FreeBSD and rxvt-unicode does not seem to work at all.
		319
		320	Rxvt-unicode requires the symbol C<__STDC_ISO_10646__> to be defined
		321	in your compile environment, or an implementation that implements it,
		322	wether it defines the symbol or not. C<__STDC_ISO_10646__> requires that
		323	B<wchar_t> is represented as unicode.
		324
		325	As you might have guessed, FreeBSD does neither define this symobl nor
		326	does it support it. Instead, it uses it's own internal representation of
		327	B<wchar_t>. This is, of course, completely fine with respect to standards.
		328
		329	However, that means rxvt-unicode only works in C<POSIX>, C<ISO-8859-1> and
		330	C<UTF-8> locales under FreeBSD (which all use Unicode as B<wchar_t>.
		331
		332	C<__STDC_ISO_10646__> is the only sane way to support multi-language
		333	apps in an OS, as using a locale-dependent (and non-standardized)
		334	representation of B<wchar_t> makes it impossible to convert between
		335	B<wchar_t> (as used by X11 and your applications) and any other encoding
		336	without implementing OS-specific-wrappers for each and every locale. There
		337	simply are no APIs to convert B<wchar_t> into anything except the current
		338	locale encoding.
		339
		340	Some applications (such as the formidable B<mlterm>) work around this
		341	by carrying their own replacement functions for character set handling
		342	with them, and either implementing OS-dependent hacks or doing multiple
		343	conversions (which is slow and unreliable in case the OS implements
		344	encodings slightly different than the terminal emulator).
		345
		346	The rxvt-unicode author insists that the right way to fix this is in the
		347	system libraries once and for all, instead of forcing every app to carry
		348	complete replacements for them :)
		349
		350	=item I use Solaris 9 and it doesn't compile/work/etc.
		351
		352	Try the diff in F<doc/solaris9.patch> as a base. It fixes the worst
		353	problems with C<wcwidth> and a compile problem.
		354
		355	=item How can I use rxvt-unicode under cygwin?
		356
		357	rxvt-unicode should compile and run out of the box on cygwin, using
		358	the X11 libraries that come with cygwin. libW11 emulation is no
		359	longer supported (and makes no sense, either, as it only supported a
		360	single font). I recommend starting the X-server in C<-multiwindow> or
		361	C<-rootless> mode instead, which will result in similar look&feel as the
		362	old libW11 emulation.
		363
		364	At the time of this writing, cygwin didn't seem to support any multi-byte
		365	encodings (you might try C<LC_CTYPE=C-UTF-8>), so you are likely limited
		366	to 8-bit encodings.
		367
		368	=item How does rxvt-unicode determine the encoding to use?
		369
		370	=item Is there an option to switch encodings?
		371
		372	Unlike some other terminals, rxvt-unicode has no encoding switch, and no
		373	specific "utf-8" mode, such as xterm. In fact, it doesn't even know about
		374	UTF-8 or any other encodings with respect to terminal I/O.
		375
		376	The reasons is that there exists a perfectly fine mechanism for selecting
		377	the encoding, doing I/O and (most important) communicating this to all
		378	applications so everybody agrees on character properties such as width
		379	and code number. This mechanism is the I<locale>. Applications not using
		380	that info will have problems (for example, C<xterm> gets the width of
		381	characters wrong as it uses it's own, locale-independent table under all
		382	locales).
		383
		384	Rxvt-unicode uses the C<LC_CTYPE> locale category to select encoding. All
		385	programs doing the same (that is, most) will automatically agree in the
		386	interpretation of characters.
		387
		388	Unfortunately, there is no system-independent way to select locales, nor
		389	is there a standard on how locale specifiers will look like.
		390
		391	On most systems, the content of the C<LC_CTYPE> environment variable
		392	contains an arbitrary string which corresponds to an already-installed
		393	locale. Common names for locales are C<en_US.UTF-8>, C<de_DE.ISO-8859-15>,
		394	C<ja_JP.EUC-JP>, i.e. C<language_country.encoding>, but other forms
		395	(i.e. C<de> or C<german>) are also common.
		396
		397	Rxvt-unicode ignores all other locale categories, and except for
		398	the encoding, ignores country or language-specific settings,
		399	i.e. C<de_DE.UTF-8> and C<ja_JP.UTF-8> are the normally same to
		400	rxvt-unicode.
		401
		402	If you want to use a specific encoding you have to make sure you start
		403	rxvt-unicode with the correct C<LC_CTYPE> category.
		404
		405	=item Can I switch locales at runtime?
		406
		407	Yes, using an escape sequence. Try something like this, which sets
		408	rxvt-unicode's idea of C<LC_CTYPE>.
		409
		410	printf '\e]701;%s\007' ja_JP.SJIS
		411
		412	See also the previous answer.
		413
		414	Sometimes this capability is rather handy when you want to work in
		415	one locale (e.g. C<de_DE.UTF-8>) but some programs don't support it
		416	(e.g. UTF-8). For example, I use this script to start C<xjdic>, which
		417	first switches to a locale supported by xjdic and back later:
		418
		419	printf '\e]701;%s\007' ja_JP.SJIS
		420	xjdic -js
		421	printf '\e]701;%s\007' de_DE.UTF-8
		422
		423	You can also use xterm's C<luit> program, which usually works fine, except
		424	for some locales where character width differs between program- and
		425	rxvt-unicode-locales.
		426
		427	=item Can I switch the fonts at runtime?
		428
		429	Yes, using an escape sequence. Try something like this, which has the same
		430	effect as using the C<-fn> switch, and takes effect immediately:
		431
		432	printf '\e]50;%s\007' "9x15bold,xft:Kochi Gothic"
		433
		434	This is useful if you e.g. work primarily with japanese (and prefer a
		435	japanese font), but you have to switch to chinese temporarily, where
		436	japanese fonts would only be in your way.
		437
		438	You can think of this as a kind of manual ISO-2022 switching.
		439
		440	=item Why do italic characters look as if clipped?
		441
		442	Many fonts have difficulties with italic characters and hinting. For
		443	example, the otherwise very nicely hinted font C<xft:Bitstream Vera Sans
		444	Mono> completely fails in it's italic face. A workaround might be to
		445	enable freetype autohinting, i.e. like this:
		446
		447	URxvt.italicFont: xft:Bitstream Vera Sans Mono:italic:autohint=true
		448	URxvt.boldItalicFont: xft:Bitstream Vera Sans Mono:bold:italic:autohint=true
		449
		450	=item My input method wants <some encoding> but I want UTF-8, what can I do?
		451
		452	You can specify separate locales for the input method and the rest of the
		453	terminal, using the resource C<imlocale>:
		454
		455	URxvt*imlocale: ja_JP.EUC-JP
		456
		457	Now you can start your terminal with C<LC_CTYPE=ja_JP.UTF-8> and still
		458	use your input method. Please note, however, that you will not be able to
		459	input characters outside C<EUC-JP> in a normal way then, as your input
		460	method limits you.
		461
		462	=item Rxvt-unicode crashes when the X Input Method changes or exits.
		463
		464	Unfortunately, this is unavoidable, as the XIM protocol is racy by
		465	design. Applications can avoid some crashes at the expense of memory
		466	leaks, and Input Methods can avoid some crashes by careful ordering at
		467	exit time. B<kinput2> (and derived input methods) generally succeeds,
		468	while B<SCIM> (or similar input methods) fails. In the end, however,
		469	crashes cannot be completely avoided even if both sides cooperate.
		470
		471	So the only workaround is not to kill your Input Method Servers.
		472
		473	=item Rxvt-unicode uses gobs of memory, how can I reduce that?
		474
		475	Rxvt-unicode tries to obey the rule of not charging you for something you
		476	don't use. One thing you should try is to configure out all settings that
		477	you don't need, for example, Xft support is a resource hog by design,
		478	when used. Compiling it out ensures that no Xft font will be loaded
		479	accidentally when rxvt-unicode tries to find a font for your characters.
		480
		481	Also, many people (me included) like large windows and even larger
		482	scrollback buffers: Without C<--enable-unicode3>, rxvt-unicode will use
		483	6 bytes per screen cell. For a 160x?? window this amounts to almost a
		484	kilobyte per line. A scrollback buffer of 10000 lines will then (if full)
		485	use 10 Megabytes of memory. With C<--enable-unicode3> it gets worse, as
		486	rxvt-unicode then uses 8 bytes per screen cell.
		487
		488	=item Can I speed up Xft rendering somehow?
		489
		490	Yes, the most obvious way to speed it up is to avoid Xft entirely, as
		491	it is simply slow. If you still want Xft fonts you might try to disable
		492	antialiasing (by appending C<:antialias=false>), which saves lots of
		493	memory and also speeds up rendering considerably.
		494
		495	=item Rxvt-unicode doesn't seem to anti-alias its fonts, what is wrong?
		496
		497	Rxvt-unicode will use whatever you specify as a font. If it needs to
		498	fall back to it's default font search list it will prefer X11 core
		499	fonts, because they are small and fast, and then use Xft fonts. It has
		500	antialiasing disabled for most of them, because the author thinks they
		501	look best that way.
		502
		503	If you want antialiasing, you have to specify the fonts manually.
		504
		505	=item Mouse cut/paste suddenly no longer works.
		506
		507	Make sure that mouse reporting is actually turned off since killing
		508	some editors prematurely may leave the mouse in mouse report mode. I've
		509	heard that tcsh may use mouse reporting unless it otherwise specified. A
		510	quick check is to see if cut/paste works when the Alt or Shift keys are
		511	depressed. See @@RXVT_NAME@@(7)
		512
		513	=item What's with this bold/blink stuff?
		514
		515	If no bold colour is set via C<colorBD:>, bold will invert text using the
		516	standard foreground colour.
		517
		518	For the standard background colour, blinking will actually make the
		519	text blink when compiled with C<--enable-blinking>. with standard
		520	colours. Without C<--enable-blinking>, the blink attribute will be
		521	ignored.
		522
		523	On ANSI colours, bold/blink attributes are used to set high-intensity
		524	foreground/background colors.
		525
		526	color0-7 are the low-intensity colors.
		527
		528	color8-15 are the corresponding high-intensity colors.
		529
		530	=item I don't like the screen colors. How do I change them?
		531
		532	You can change the screen colors at run-time using F<~/.Xdefaults>
		533	resources (or as long-options).
		534
		535	Here are values that are supposed to resemble a VGA screen,
		536	including the murky brown that passes for low-intensity yellow:
		537
		538	URxvt.color0: #000000
		539	URxvt.color1: #A80000
		540	URxvt.color2: #00A800
		541	URxvt.color3: #A8A800
		542	URxvt.color4: #0000A8
		543	URxvt.color5: #A800A8
		544	URxvt.color6: #00A8A8
		545	URxvt.color7: #A8A8A8
		546
		547	URxvt.color8: #000054
		548	URxvt.color9: #FF0054
		549	URxvt.color10: #00FF54
		550	URxvt.color11: #FFFF54
		551	URxvt.color12: #0000FF
		552	URxvt.color13: #FF00FF
		553	URxvt.color14: #00FFFF
		554	URxvt.color15: #FFFFFF
		555
		556	And here is a more complete set of non-standard colors described (not by
		557	me) as "pretty girly".
		558
		559	URxvt.cursorColor: #dc74d1

		577
		578	=item How can I start @@RXVT_NAME@@d in a race-free way?
		579
		580	Try C<@@RXVT_NAME@@d -f -o>, which tells @@RXVT_NAME@@d to open the
		581	display, create the listening socket and then fork.
		582
		583	=item What's with the strange Backspace/Delete key behaviour?
		584
		585	Assuming that the physical Backspace key corresponds to the
		586	BackSpace keysym (not likely for Linux ... see the following
		587	question) there are two standard values that can be used for
		588	Backspace: C<^H> and C<^?>.
		589
		590	Historically, either value is correct, but rxvt-unicode adopts the debian
		591	policy of using C<^?> when unsure, because it's the one only only correct
		592	choice :).
		593
		594	Rxvt-unicode tries to inherit the current stty settings and uses the value
		595	of `erase' to guess the value for backspace. If rxvt-unicode wasn't
		596	started from a terminal (say, from a menu or by remote shell), then the
		597	system value of `erase', which corresponds to CERASE in <termios.h>, will
		598	be used (which may not be the same as your stty setting).
		599
		600	For starting a new rxvt-unicode:
		601
		602	# use Backspace = ^H
		603	$ stty erase ^H
		604	$ @@RXVT_NAME@@
		605
		606	# use Backspace = ^?
		607	$ stty erase ^?
		608	$ @@RXVT_NAME@@
		609
		610	Toggle with C<ESC [ 36 h> / C<ESC [ 36 l> as documented in @@RXVT_NAME@@(7).
		611
		612	For an existing rxvt-unicode:
		613
		614	# use Backspace = ^H
		615	$ stty erase ^H
		616	$ echo -n "^[[36h"
		617
		618	# use Backspace = ^?
		619	$ stty erase ^?
		620	$ echo -n "^[[36l"
		621
		622	This helps satisfy some of the Backspace discrepancies that occur, but
		623	if you use Backspace = C<^H>, make sure that the termcap/terminfo value
		624	properly reflects that.
		625
		626	The Delete key is a another casualty of the ill-defined Backspace problem.
		627	To avoid confusion between the Backspace and Delete keys, the Delete
		628	key has been assigned an escape sequence to match the vt100 for Execute
		629	(C<ESC [ 3 ~>) and is in the supplied termcap/terminfo.
		630
		631	Some other Backspace problems:
		632
		633	some editors use termcap/terminfo,
		634	some editors (vim I'm told) expect Backspace = ^H,
		635	GNU Emacs (and Emacs-like editors) use ^H for help.
		636
		637	Perhaps someday this will all be resolved in a consistent manner.
		638
		639	=item I don't like the key-bindings. How do I change them?
		640
		641	There are some compile-time selections available via configure. Unless
		642	you have run "configure" with the C<--disable-resources> option you can
		643	use the `keysym' resource to alter the keystrings associated with keysyms.
		644
		645	Here's an example for a URxvt session started using C<@@RXVT_NAME@@ -name URxvt>
		646

		670	=item I'm using keyboard model XXX that has extra Prior/Next/Insert keys.
		671	How do I make use of them? For example, the Sun Keyboard type 4
		672	has the following mappings that rxvt-unicode doesn't recognize.
		673
		674	KP_Insert == Insert
		675	F22 == Print
		676	F27 == Home
		677	F29 == Prior
		678	F33 == End
		679	F35 == Next
		680
		681	Rather than have rxvt-unicode try to accommodate all the various possible
		682	keyboard mappings, it is better to use `xmodmap' to remap the keys as
		683	required for your particular machine.
		684
		685	=item How do I distinguish wether I'm running rxvt-unicode or a regular xterm?
		686	I need this to decide about setting colors etc.
		687
		688	rxvt and rxvt-unicode always export the variable "COLORTERM", so you can
		689	check and see if that is set. Note that several programs, JED, slrn,
		690	Midnight Commander automatically check this variable to decide whether or
		691	not to use color.
		692
		693	=item How do I set the correct, full IP address for the DISPLAY variable?
		694
		695	If you've compiled rxvt-unicode with DISPLAY_IS_IP and have enabled
		696	insecure mode then it is possible to use the following shell script
		697	snippets to correctly set the display. If your version of rxvt-unicode
		698	wasn't also compiled with ESCZ_ANSWER (as assumed in these snippets) then
		699	the COLORTERM variable can be used to distinguish rxvt-unicode from a
		700	regular xterm.

		2227	for Xft fonts, although having them compiled in lets rxvt-unicode choose
		2228	replacement fonts more intelligently. Compiling them in will make your
		2229	binary bigger (all of together cost about 700kB), but it doesn't increase
		2230	memory usage unless you use a font requiring one of these encodings.

		2232	=begin table
		2233
		2234	all all available codeset groups
		2235	zh common chinese encodings
		2236	zh_ext rarely used but very big chinese encodigs
		2237	jp common japanese encodings
		2238	jp_ext rarely used but big japanese encodings
		2239	kr korean encodings
		2240
		2241	=end table
		2242
		2243	=item --enable-xim (default: on)
		2244
		2245	Add support for XIM (X Input Method) protocol. This allows using
		2246	alternative input methods (e.g. kinput2) and will also correctly
		2247	set up the input for people using dead keys or compose keys.
		2248
		2249	=item --enable-unicode3 (default: off)
		2250
		2251	Enable direct support for displaying unicode codepoints above
		2252	65535 (the basic multilingual page). This increases storage
		2253	requirements per character from 2 to 4 bytes. X11 fonts do not yet
		2254	support these extra characters, but Xft does.
		2255
		2256	Please note that rxvt-unicode can store unicode code points >65535
		2257	even without this flag, but the number of such characters is
		2258	limited to a view thousand (shared with combining characters,
		2259	see next switch), and right now rxvt-unicode cannot display them
		2260	(input/output and cut&paste still work, though).
		2261
		2262	=item --enable-combining (default: on)
		2263
		2264	Enable automatic composition of combining characters into
		2265	composite characters. This is required for proper viewing of text
		2266	where accents are encoded as seperate unicode characters. This is
		2267	done by using precomposited characters when available or creating
		2268	new pseudo-characters when no precomposed form exists.
		2269
		2270	Without --enable-unicode3, the number of additional precomposed characters
		2271	is rather limited (2048, if this is full, rxvt-unicode will use the
		2272	private use area, extending the number of combinations to 8448). With
		2273	--enable-unicode3, no practical limit exists.
		2274
		2275	This option will also enable storage (but not display) of characters
		2276	beyond plane 0 (>65535) when --enable-unicode3 was not specified.
		2277
		2278	The combining table also contains entries for arabic presentation forms,
		2279	but these are not currently used. Bug me if you want these to be used (and
		2280	tell me how these are to be used...).
		2281
		2282	=item --enable-fallback(=CLASS) (default: Rxvt)
		2283
		2284	When reading resource settings, also read settings for class CLASS. To disable resource fallback use --disable-fallback.
		2285
		2286	=item --with-res-name=NAME (default: urxvt)
		2287
		2288	Use the given name as default application name when
		2289	reading resources. Specify --with-res-name=rxvt to replace rxvt.
		2290
		2291	=item --with-res-class=CLASS /default: URxvt)
		2292
		2293	Use the given class as default application class
		2294	when reading resources. Specify --with-res-class=Rxvt to replace
		2295	rxvt.
		2296
		2297	=item --enable-utmp (default: on)
		2298
		2299	Write user and tty to utmp file (used by programs like F<w>) at
		2300	start of rxvt execution and delete information when rxvt exits.
		2301
		2302	=item --enable-wtmp (default: on)
		2303
		2304	Write user and tty to wtmp file (used by programs like F<last>) at
		2305	start of rxvt execution and write logout when rxvt exits. This
		2306	option requires --enable-utmp to also be specified.
		2307
		2308	=item --enable-lastlog (default: on)
		2309
		2310	Write user and tty to lastlog file (used by programs like
		2311	F<lastlogin>) at start of rxvt execution. This option requires
		2312	--enable-utmp to also be specified.
		2313
		2314	=item --enable-xpm-background (default: off)
		2315
		2316	Add support for XPM background pixmaps.
		2317
		2318	=item --enable-transparency (default: off)
		2319
		2320	Add support for inheriting parent backgrounds thus giving a fake
		2321	transparency to the term.
		2322
		2323	=item --enable-fading (default: on)
		2324
		2325	Add support for fading the text when focus is lost (requires C<--enable-transparency>).
		2326
		2327	=item --enable-tinting (default: on)
		2328
		2329	Add support for tinting of transparent backgrounds (requires C<--enable-transparency>).
		2330
		2331	=item --enable-menubar (default: off)
		2332
		2333	Add support for our menu bar system (this interacts badly with
		2334	dynamic locale switching currently).
		2335
		2336	=item --enable-rxvt-scroll (default: on)
		2337
		2338	Add support for the original rxvt scrollbar.
		2339
		2340	=item --enable-next-scroll (default: on)
		2341
		2342	Add support for a NeXT-like scrollbar.
		2343
		2344	=item --enable-xterm-scroll (default: on)
		2345
		2346	Add support for an Xterm-like scrollbar.
		2347
		2348	=item --enable-plain-scroll (default: on)
		2349
		2350	Add support for a very unobtrusive, plain-looking scrollbar that
		2351	is the favourite of the rxvt-unicode author, having used it for
		2352	many years.
		2353
		2354	=item --enable-half-shadow (default: off)
		2355
		2356	Make shadows on the scrollbar only half the normal width & height.
		2357	only applicable to rxvt scrollbars.
		2358
		2359	=item --enable-ttygid (default: off)
		2360
		2361	Change tty device setting to group "tty" - only use this if
		2362	your system uses this type of security.
		2363
		2364	=item --disable-backspace-key
		2365
		2366	Removes any handling of the backspace key by us - let the X server do it.
		2367
		2368	=item --disable-delete-key
		2369
		2370	Removes any handling of the delete key by us - let the X server
		2371	do it.
		2372
		2373	=item --disable-resources
		2374
		2375	Removes any support for resource checking.
		2376
		2377	=item --enable-xgetdefault
		2378
		2379	Make resources checking via XGetDefault() instead of our small
		2380	version which only checks ~/.Xdefaults, or if that doesn't exist then
		2381	~/.Xresources.
		2382
		2383	Please note that nowadays, things like XIM will automatically pull in and
		2384	use the full X resource manager, so the overhead of using it might be very
		2385	small, if nonexistant.
		2386
		2387	=item --enable-strings (default: off)
		2388
		2389	Add support for our possibly faster memset() function and other
		2390	various routines, overriding your system's versions which may
		2391	have been hand-crafted in assembly or may require extra libraries
		2392	to link in. (this breaks ANSI-C rules and has problems on many
		2393	GNU/Linux systems).
		2394
		2395	=item --disable-swapscreen
		2396
		2397	Remove support for secondary/swap screen.
		2398
		2399	=item --enable-frills (default: on)
		2400
		2401	Add support for many small features that are not essential but nice to
		2402	have. Normally you want this, but for very small binaries you may want to
		2403	disable this.
		2404
		2405	A non-exhaustive list of features enabled by C<--enable-frills> (possibly
		2406	in combination with other switches) is:
		2407
		2408	MWM-hints
		2409	EWMH-hints (pid, utf8 names) and protocols (ping)
		2410	seperate underline colour
		2411	settable border widths and borderless switch
		2412	settable extra linespacing
		2413	iso-14755-2 and -3, and visual feedback
		2414	backindex and forwardindex escape sequence
		2415	window op and some xterm/OSC escape sequences
		2416	tripleclickwords
		2417	settable insecure mode
		2418	keysym remapping support
		2419	cursor blinking and underline cursor
		2420	-embed and -pty-fd options
		2421
		2422	=item --enable-iso14755 (default: on)
		2423
		2424	Enable extended ISO 14755 support (see @@RXVT_NAME@@(1), or
		2425	F<doc/rxvt.1.txt>). Basic support (section 5.1) is enabled by
		2426	C<--enable-frills>, while support for 5.2, 5.3 and 5.4 is enabled with
		2427	this switch.
		2428
		2429	=item --enable-keepscrolling (default: on)
		2430
		2431	Add support for continual scrolling of the display when you hold
		2432	the mouse button down on a scrollbar arrow.
		2433
		2434	=item --enable-mousewheel (default: on)
		2435
		2436	Add support for scrolling via mouse wheel or buttons 4 & 5.
		2437
		2438	=item --enable-slipwheeling (default: on)
		2439
		2440	Add support for continual scrolling (using the mouse wheel as an
		2441	accelerator) while the control key is held down. This option
		2442	requires --enable-mousewheel to also be specified.
		2443
		2444	=item --disable-new-selection
		2445
		2446	Remove support for mouse selection style like that of xterm.
		2447
		2448	=item --enable-dmalloc (default: off)
		2449
		2450	Use Gray Watson's malloc - which is good for debugging See
		2451	http://www.letters.com/dmalloc/ for details If you use either this or the
		2452	next option, you may need to edit src/Makefile after compiling to point
		2453	DINCLUDE and DLIB to the right places.
		2454
		2455	You can only use either this option and the following (should
		2456	you use either) .
		2457
		2458	=item --enable-dlmalloc (default: off)
		2459
		2460	Use Doug Lea's malloc - which is good for a production version
		2461	See L<http://g.oswego.edu/dl/html/malloc.html> for details.
		2462
		2463	=item --enable-smart-resize (default: on)
		2464
		2465	Add smart growth/shrink behaviour when changing font size via hot
		2466	keys. This should keep the window corner which is closest to a corner of
		2467	the screen in a fixed position.
		2468
		2469	=item --enable-pointer-blank (default: on)
		2470
		2471	Add support to have the pointer disappear when typing or inactive.
		2472
		2473	=item --with-name=NAME (default: urxvt)
		2474
		2475	Set the basename for the installed binaries, resulting
		2476	in C<urxvt>, C<urxvtd> etc.). Specify C<--with-name=rxvt> to replace with
		2477	C<rxvt>.
		2478
		2479	=item --with-term=NAME (default: rxvt-unicode)
		2480
		2481	Change the environmental variable for the terminal to NAME.
		2482
		2483	=item --with-terminfo=PATH
		2484
		2485	Change the environmental variable for the path to the terminfo tree to
		2486	PATH.
		2487
		2488	=item --with-x
		2489
		2490	Use the X Window System (pretty much default, eh?).
		2491
		2492	=item --with-xpm-includes=DIR
		2493
		2494	Look for the XPM includes in DIR.
		2495
		2496	=item --with-xpm-library=DIR
		2497
		2498	Look for the XPM library in DIR.
		2499
		2500	=item --with-xpm
		2501
		2502	Not needed - define via --enable-xpm-background.

		2507
		2508	Marc Lehmann <rxvt@schmorp.de> converted this document to pod and
		2509	reworked it from the original Rxvt documentation, which was done by Geoff
		2510	Wing <gcw@pobox.com>, who in turn used the XTerm documentation and other
		2511	sources.
