		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 contains large patches that
		37	considerably change the behaviour of rxvt-unicode. Before reporting a
		38	bug to the original rxvt-unicode author please download and install the
		39	genuine version (L<http://software.schmorp.de#rxvt-unicode>) and try to
		40	reproduce the problem. If you cannot, chances are that the problems are
		41	specific to Debian GNU/Linux, in which case it should be reported via the
		42	Debian Bug Tracking System (use C<reportbug> to report the bug).
		43
		44	For other problems that also affect the Debian package, you can and
		45	probably should use the Debian BTS, too, because, after all, it's also a
		46	bug in the Debian version and it serves as a reminder for other users that
		47	might encounter the same issue.
		48
		49	=item When I log-in to another system it tells me about missing terminfo data?
		50
		51	The terminal description used by rxvt-unicode is not as widely available
		52	as that for xterm, or even rxvt (for which the same problem often arises).
		53
		54	The correct solution for this problem is to install the terminfo, this can
		55	be done like this (with ncurses' infocmp):
		56
		57	REMOTE=remotesystem.domain
		58	infocmp rxvt-unicode \| ssh $REMOTE "cat >/tmp/ti && tic /tmp/ti"
		59
		60	... or by installing rxvt-unicode normally on the remote system,
		61
		62	If you cannot or do not want to do this, then you can simply set
		63	C<TERM=rxvt> or even C<TERM=xterm>, and live with the small number of
		64	problems arising, which includes wrong keymapping, less and different
		65	colours and some refresh errors in fullscreen applications. It's a nice
		66	quick-and-dirty workaround for rare cases, though.
		67
		68	If you always want to do this (and are fine with the consequences) you
		69	can either recompile rxvt-unicode with the desired TERM value or use a
		70	resource to set it:
		71
		72	URxvt.termName: rxvt
		73
		74	If you don't plan to use B<rxvt> (quite common...) you could also replace
		75	the rxvt terminfo file with the rxvt-unicode one.
		76
		77	=item C<bash>'s readline does not work correctly under @@RXVT_NAME@@.
		78
		79	=item I need a termcap file entry.
		80
		81	One reason you might want this is that some distributions or operating
		82	systems still compile some programs using the long-obsoleted termcap
		83	library (Fedora Core's bash is one example) and rely on a termcap entry
		84	for C<rxvt-unicode>.
		85
		86	You could use rxvt's termcap entry with resonable results in many cases.
		87	You can also create a termcap entry by using terminfo's infocmp program
		88	like this:
		89
		90	infocmp -C rxvt-unicode
		91
		92	Or you could use this termcap entry, generated by the command above:

		114
		115	=item Why does C<ls> no longer have coloured output?
		116
		117	The C<ls> in the GNU coreutils unfortunately doesn't use terminfo to
		118	decide wether a terminal has colour, but uses it's own configuration
		119	file. Needless to say, C<rxvt-unicode> is not in it's default file (among
		120	with most other terminals supporting colour). Either add:
		121
		122	TERM rxvt-unicode
		123
		124	to C</etc/DIR_COLORS> or simply add:
		125
		126	alias ls='ls --color=auto'
		127
		128	to your C<.profile> or C<.bashrc>.
		129
		130	=item Why doesn't vim/emacs etc. use the 88 colour mode?
		131
		132	=item Why doesn't vim/emacs etc. make use of italic?
		133
		134	=item Why are the secondary screen-related options not working properly?
		135
		136	Make sure you are using C<TERM=rxvt-unicode>. Some pre-packaged
		137	distributions (most notably Debian GNU/Linux) break rxvt-unicode
		138	by setting C<TERM> to C<rxvt>, which doesn't have these extra
		139	features. Unfortunately, some of these (most notably, again, Debian
		140	GNU/Linux) furthermore fail to even install the C<rxvt-unicode> terminfo
		141	file, so you will need to install it on your own (See the question B<When
		142	I log-in to another system it tells me about missing terminfo data?> on
		143	how to do this).
		144
		145	=item My numerical keypad acts weird and generates differing output?
		146
		147	Some Debian GNUL/Linux users seem to have this problem, although no
		148	specific details were reported so far. It is possible that this is caused
		149	by the wrong C<TERM> setting, although the details of wether and how
		150	this can happen are unknown, as C<TERM=rxvt> should offer a compatible
		151	keymap. See the answer to the previous question, and please report if that
		152	helped.
		153
		154	=item Rxvt-unicode does not seem to understand the selected encoding?
		155
		156	=item Unicode does not seem to work?
		157
		158	If you encounter strange problems like typing an accented character but
		159	getting two unrelated other characters or similar, or if program output is
		160	subtly garbled, then you should check your locale settings.
		161
		162	Rxvt-unicode must be started with the same C<LC_CTYPE> setting as the
		163	programs. Often rxvt-unicode is started in the C<C> locale, while the
		164	login script running within the rxvt-unicode window changes the locale to
		165	something else, e.g. C<en_GB.UTF-8>. Needless to say, this is not going to work.
		166
		167	The best thing is to fix your startup environment, as you will likely run
		168	into other problems. If nothing works you can try this in your .profile.
		169
		170	printf '\e]701;%s\007' "$LC_CTYPE"
		171
		172	If this doesn't work, then maybe you use a C<LC_CTYPE> specification not
		173	supported on your systems. Some systems have a C<locale> command which
		174	displays this (also, C<perl -e0> can be used to check locale settings, as
		175	it will complain loudly if it cannot set the locale). If it displays something
		176	like:
		177
		178	locale: Cannot set LC_CTYPE to default locale: ...
		179
		180	Then the locale you specified is not supported on your system.
		181
		182	If nothing works and you are sure that everything is set correctly then
		183	you will need to remember a little known fact: Some programs just don't
		184	support locales :(
		185
		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, that means rxvt-unicode only works in C<POSIX>, C<ISO-8859-1> and
		316	C<UTF-8> locales under FreeBSD (which all use Unicode as B<wchar_t>.
		317
		318	C<__STDC_ISO_10646__> is the only sane way to support multi-language
		319	apps in an OS, as using a locale-dependent (and non-standardized)
		320	representation of B<wchar_t> makes it impossible to convert between
		321	B<wchar_t> (as used by X11 and your applications) and any other encoding
		322	without implementing OS-specific-wrappers for each and every locale. There
		323	simply are no APIs to convert B<wchar_t> into anything except the current
		324	locale encoding.
		325
		326	Some applications (such as the formidable B<mlterm>) work around this
		327	by carrying their own replacement functions for character set handling
		328	with them, and either implementing OS-dependent hacks or doing multiple
		329	conversions (which is slow and unreliable in case the OS implements
		330	encodings slightly different than the terminal emulator).
		331
		332	The rxvt-unicode author insists that the right way to fix this is in the
		333	system libraries once and for all, instead of forcing every app to carry
		334	complete replacements for them :)
		335
		336	=item How does rxvt-unicode determine the encoding to use?
		337
		338	=item Is there an option to switch encodings?
		339
		340	Unlike some other terminals, rxvt-unicode has no encoding switch, and no
		341	specific "utf-8" mode, such as xterm. In fact, it doesn't even know about
		342	UTF-8 or any other encodings with respect to terminal I/O.
		343
		344	The reasons is that there exists a perfectly fine mechanism for selecting
		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
		352	Rxvt-unicode uses the C<LC_CTYPE> locale category to select encoding. All
		353	programs doing the same (that is, most) will automatically agree in the
		354	interpretation of characters.
		355
		356	Unfortunately, there is no system-independent way to select locales, nor
		357	is there a standard on how locale specifiers will look like.
		358
		359	On most systems, the content of the C<LC_CTYPE> environment variable
		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
		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
		473	=item Mouse cut/paste suddenly no longer works.
		474
		475	Make sure that mouse reporting is actually turned off since killing
		476	some editors prematurely may leave the mouse in mouse report mode. I've
		477	heard that tcsh may use mouse reporting unless it otherwise specified. A
		478	quick check is to see if cut/paste works when the Alt or Shift keys are
		479	depressed. See @@RXVT_NAME@@(7)
		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.
		497
		498	=item I don't like the screen colors. How do I change them?
		499
		500	You can change the screen colors at run-time using F<~/.Xdefaults>
		501	resources (or as long-options).
		502
		503	Here are values that are supposed to resemble a VGA screen,
		504	including the murky brown that passes for low-intensity yellow:
		505
		506	URxvt.color0: #000000
		507	URxvt.color1: #A80000
		508	URxvt.color2: #00A800

		514
		515	URxvt.color8: #000054
		516	URxvt.color9: #FF0054

		522	URxvt.color15: #FFFFFF
		523
		524	And here is a more complete set of non-standard colors described (not by
		525	me) as "pretty girly".

		546	=item How can I start @@RXVT_NAME@@d in a race-free way?
		547
		548	Despite it's name, @@RXVT_NAME@@d is not a real daemon, but more like a
		549	server that answers @@RXVT_NAME@@c's requests, so it doesn't background
		550	itself.
		551
		552	To ensure @@RXVT_NAME@@d is listening on it's socket, you can use the
		553	following method to wait for the startup message before continuing:

		557	=item What's with the strange Backspace/Delete key behaviour?
		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 = ^?
		581	$ stty erase ^?
		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.
		610
		611	Perhaps someday this will all be resolved in a consistent manner.
		612
		613	=item I don't like the key-bindings. How do I change them?
		614
		615	There are some compile-time selections available via configure. Unless
		616	you have run "configure" with the C<--disable-resources> option you can
		617	use the `keysym' resource to alter the keystrings associated with keysyms.

		644	=item I'm using keyboard model XXX that has extra Prior/Next/Insert keys.
		645	How do I make use of them? For example, the Sun Keyboard type 4
		646	has the following mappings that rxvt-unicode doesn't recognize.
		647
		648	KP_Insert == Insert
		649	F22 == Print
		650	F27 == Home
		651	F29 == Prior
		652	F33 == End
		653	F35 == Next
		654
		655	Rather than have rxvt-unicode try to accommodate all the various possible
		656	keyboard mappings, it is better to use `xmodmap' to remap the keys as
		657	required for your particular machine.
		658
		659	=item How do I distinguish wether I'm running rxvt-unicode or a regular xterm?
		660	I need this to decide about setting colors etc.
		661
		662	rxvt and rxvt-unicode always export the variable "COLORTERM", so you can
		663	check and see if that is set. Note that several programs, JED, slrn,
		664	Midnight Commander automatically check this variable to decide whether or
		665	not to use color.
		666
		667	=item How do I set the correct, full IP address for the DISPLAY variable?
		668
		669	If you've compiled rxvt-unicode with DISPLAY_IS_IP and have enabled
		670	insecure mode then it is possible to use the following shell script
		671	snippets to correctly set the display. If your version of rxvt-unicode
		672	wasn't also compiled with ESCZ_ANSWER (as assumed in these snippets) then
		673	the COLORTERM variable can be used to distinguish rxvt-unicode from a
		674	regular xterm.

		2161	=head1 CONFIGURE OPTIONS
		2162
		2163	General hint: if you get compile errors, then likely your configuration
		2164	hasn't been tested well. Either try with --enable-everything or use the
		2165	./reconf script as a base for experiments. ./reconf is used by myself,
		2166	so it should generally be a working config. Of course, you should always
		2167	report when a combination doesn't work, so it can be fixed. Marc Lehmann
		2168	<rxvt@schmorp.de>.
		2169
		2170	=over 4
		2171
		2172	=item --enable-everything
		2173
		2174	Add support for all non-multichoice options listed in "./configure
		2175	--help". Note that unlike other enable options this is order dependant.
		2176	You can specify this and then disable options which this enables by
		2177	I<following> this with the appropriate commands.
		2178
		2179	=item --enable-xft
		2180
		2181	Add support for Xft (anti-aliases, among others) fonts. Xft fonts are
		2182	slower and require lots of memory, but as long as you don't use them, you
		2183	don't pay for them.
		2184
		2185	=item --enable-font-styles
		2186
		2187	Add support for B<bold>, I<italic> and B<< I<bold italic> >> font
		2188	styles. The fonts can be set manually or automatically.
		2189
		2190	=item --with-codesets=NAME,...
		2191
		2192	Compile in support for additional codeset (encoding) groups (C<eu>, C<vn>
		2193	are always compiled in, which includes most 8-bit character sets). These
		2194	codeset tables are used for driving X11 core fonts, they are not required
		2195	for Xft fonts, although having them compiled in lets rxvt-unicode choose
		2196	replacement fonts more intelligently. Compiling them in will make your
		2197	binary bigger (all of together cost about 700kB), but it doesn't increase
		2198	memory usage unless you use a font requiring one of these encodings.

		2208
		2209	=end table
		2210
		2211	=item --enable-xim
		2212
		2213	Add support for XIM (X Input Method) protocol. This allows using
		2214	alternative input methods (e.g. kinput2) and will also correctly
		2215	set up the input for people using dead keys or compose keys.
		2216
		2217	=item --enable-unicode3
		2218
		2219	Enable direct support for displaying unicode codepoints above
		2220	65535 (the basic multilingual page). This increases storage
		2221	requirements per character from 2 to 4 bytes. X11 fonts do not yet
		2222	support these extra characters, but Xft does.
		2223
		2224	Please note that rxvt-unicode can store unicode code points >65535
		2225	even without this flag, but the number of such characters is
		2226	limited to a view thousand (shared with combining characters,
		2227	see next switch), and right now rxvt-unicode cannot display them
		2228	(input/output and cut&paste still work, though).
		2229
		2230	=item --enable-combining
		2231
		2232	Enable automatic composition of combining characters into
		2233	composite characters. This is required for proper viewing of text
		2234	where accents are encoded as seperate unicode characters. This is
		2235	done by using precomposited characters when available or creating
		2236	new pseudo-characters when no precomposed form exists.
		2237
		2238	Without --enable-unicode3, the number of additional precomposed characters
		2239	is rather limited (2048, if this is full, rxvt-unicode will use the
		2240	private use area, extending the number of combinations to 8448). With
		2241	--enable-unicode3, no practical limit exists.
		2242
		2243	This option will also enable storage (but not display) of characters
		2244	beyond plane 0 (>65535) when --enable-unicode3 was not specified.
		2245
		2246	The combining table also contains entries for arabic presentation forms,
		2247	but these are not currently used. Bug me if you want these to be used (and
		2248	tell me how these are to be used...).
		2249

		2253	(default: Rxvt). To disable resource fallback use --disable-fallback.
		2254
		2255	=item --with-res-name=NAME

		2259
		2260	=item --with-res-class=CLASS

		2270
		2271	=item --enable-wtmp
		2272
		2273	Write user and tty to wtmp file (used by programs like F<last>) at
		2274	start of rxvt execution and write logout when rxvt exits. This
		2275	option requires --enable-utmp to also be specified.
		2276

		2278
		2279	Write user and tty to lastlog file (used by programs like

		2329
		2330	Change tty device setting to group "tty" - only use this if
		2331	your system uses this type of security.
		2332
		2333	=item --disable-backspace-key
		2334
		2335	Disable any handling of the backspace key by us - let the X server
		2336	do it.
		2337
		2338	=item --disable-delete-key
		2339
		2340	Disable any handling of the delete key by us - let the X server
		2341	do it.
		2342
		2343	=item --disable-resources
		2344
		2345	Remove all resources checking.
		2346
		2347	=item --enable-xgetdefault
		2348
		2349	Make resources checking via XGetDefault() instead of our small
		2350	version which only checks ~/.Xdefaults, or if that doesn't exist then
		2351	~/.Xresources.
		2352
		2353	Please note that nowadays, things like XIM will automatically pull in and
		2354	use the full X resource manager, so the overhead of using it might be very
		2355	small, if nonexistant.
		2356
		2357	=item --enable-strings
		2358
		2359	Add support for our possibly faster memset() function and other
		2360	various routines, overriding your system's versions which may
		2361	have been hand-crafted in assembly or may require extra libraries
		2362	to link in. (this breaks ANSI-C rules and has problems on many
		2363	GNU/Linux systems).
		2364
		2365	=item --disable-swapscreen
		2366
		2367	Remove support for swap screen.
		2368
		2369	=item --enable-frills
		2370
		2371	Add support for many small features that are not essential but nice to
		2372	have. Normally you want this, but for very small binaries you may want to
		2373	disable this.
		2374
		2375	A non-exhaustive list of features enabled by C<--enable-frills> (possibly
		2376	in combination with other switches) is:
		2377
		2378	MWM-hints
		2379	EWMH-hints (pid, utf8 names) and protocols (ping)
		2380	seperate underline colour
		2381	settable border widths and borderless switch
		2382	settable extra linespacing
		2383	iso-14755-2 and -3, and visual feedback
		2384	backindex and forwardindex escape sequence
		2385	window op and some xterm/OSC escape sequences
		2386	tripleclickwords
		2387	settable insecure mode
		2388	keysym remapping support
		2389	cursor blinking and underline cursor
		2390	-embed and -pty-fd options
		2391
		2392	=item --enable-iso14755
		2393
		2394	Enable extended ISO 14755 support (see @@RXVT_NAME@@(1), or
		2395	F<doc/rxvt.1.txt>). Basic support (section 5.1) is enabled by
		2396	C<--enable-frills>, while support for 5.2, 5.3 and 5.4 is enabled with
		2397	this switch.
		2398
		2399	=item --enable-keepscrolling
		2400
		2401	Add support for continual scrolling of the display when you hold
		2402	the mouse button down on a scrollbar arrow.
		2403
		2404	=item --enable-mousewheel
		2405
		2406	Add support for scrolling via mouse wheel or buttons 4 & 5.
		2407
		2408	=item --enable-slipwheeling
		2409
		2410	Add support for continual scrolling (using the mouse wheel as an
		2411	accelerator) while the control key is held down. This option
		2412	requires --enable-mousewheel to also be specified.
		2413
		2414	=item --disable-new-selection
		2415
		2416	Remove support for mouse selection style like that of xterm.
		2417
		2418	=item --enable-dmalloc
		2419
		2420	Use Gray Watson's malloc - which is good for debugging See
		2421	http://www.letters.com/dmalloc/ for details If you use either this or the
		2422	next option, you may need to edit src/Makefile after compiling to point
		2423	DINCLUDE and DLIB to the right places.
		2424
		2425	You can only use either this option and the following (should
		2426	you use either) .
		2427
		2428	=item --enable-dlmalloc
		2429
		2430	Use Doug Lea's malloc - which is good for a production version
		2431	See L<http://g.oswego.edu/dl/html/malloc.html> for details.
		2432
		2433	=item --enable-smart-resize
		2434
		2435	Add smart growth/shrink behaviour when changing font size via from hot
		2436	keys. This should keep in a fixed position the rxvt corner which is
		2437	closest to a corner of the screen.
		2438
		2439	=item --enable-pointer-blank
		2440
		2441	Add support to have the pointer disappear when typing or inactive.
		2442
		2443	=item --with-name=NAME
		2444
		2445	Set the basename for the installed binaries (default: C<urxvt>, resulting
		2446	in C<urxvt>, C<urxvtd> etc.). Specify C<--with-name=rxvt> to replace with
		2447	C<rxvt>.
		2448
		2449	=item --with-term=NAME
		2450
		2451	Change the environmental variable for the terminal to NAME (default
		2452	C<rxvt-unicode>)
		2453
		2454	=item --with-terminfo=PATH
		2455
		2456	Change the environmental variable for the path to the terminfo tree to
		2457	PATH.
		2458
		2459	=item --with-x
		2460
		2461	Use the X Window System (pretty much default, eh?).
		2462
		2463	=item --with-xpm-includes=DIR
		2464
		2465	Look for the XPM includes in DIR.
		2466
		2467	=item --with-xpm-library=DIR
		2468
		2469	Look for the XPM library in DIR.
		2470
		2471	=item --with-xpm
		2472
		2473	Not needed - define via --enable-xpm-background.
		2474
		2475	=back
