		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.

		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 do I distinguish wether I'm running rxvt-unicode or a regular xterm? I need this to decide about setting colors etc.
		79
		80	The original rxvt and rxvt-unicode always export the variable "COLORTERM",
		81	so you can check and see if that is set. Note that several programs, JED,
		82	slrn, Midnight Commander automatically check this variable to decide
		83	whether or not to use color.
		84
		85	=head3 How do I set the correct, full IP address for the DISPLAY variable?
		86
		87	If you've compiled rxvt-unicode with DISPLAY_IS_IP and have enabled
		88	insecure mode then it is possible to use the following shell script
		89	snippets to correctly set the display. If your version of rxvt-unicode
		90	wasn't also compiled with ESCZ_ANSWER (as assumed in these snippets) then
		91	the COLORTERM variable can be used to distinguish rxvt-unicode from a
		92	regular xterm.
		93
		94	Courtesy of Chuck Blake <cblake@BBN.COM> with the following shell script
		95	snippets:

		99	if [ ${TERM:-foo} = xterm ]; then
		100	stty -icanon -echo min 0 time 15 # see if enhanced rxvt or not

		105	echo -n '^[[7n' # query the rxvt we are in for the DISPLAY string
		106	read DISPLAY # set it in our local shell
		107	fi
		108	fi
		109
		110	=head3 How do I compile the manual pages on my own?
		111
		112	You need to have a recent version of perl installed as F</usr/bin/perl>,
		113	one that comes with F<pod2man>, F<pod2text> and F<pod2html>. Then go to
		114	the doc subdirectory and enter C<make alldoc>.
		115
		116	=head3 Isn't rxvt-unicode supposed to be small? Don't all those features bloat?
		117
		118	I often get asked about this, and I think, no, they didn't cause extra
		119	bloat. If you compare a minimal rxvt and a minimal urxvt, you can see
		120	that the urxvt binary is larger (due to some encoding tables always being
		121	compiled in), but it actually uses less memory (RSS) after startup. Even
		122	with C<--disable-everything>, this comparison is a bit unfair, as many
		123	features unique to urxvt (locale, encoding conversion, iso14755 etc.) are
		124	already in use in this mode.
		125
		126	text data bss drs rss filename
		127	98398 1664 24 15695 1824 rxvt --disable-everything
		128	188985 9048 66616 18222 1788 urxvt --disable-everything
		129
		130	When you C<--enable-everything> (which _is_ unfair, as this involves xft
		131	and full locale/XIM support which are quite bloaty inside libX11 and my
		132	libc), the two diverge, but not unreasnobaly so.
		133
		134	text data bss drs rss filename
		135	163431 2152 24 20123 2060 rxvt --enable-everything
		136	1035683 49680 66648 29096 3680 urxvt --enable-everything
		137
		138	The very large size of the text section is explained by the east-asian
		139	encoding tables, which, if unused, take up disk space but nothing else
		140	and can be compiled out unless you rely on X11 core fonts that use those
		141	encodings. The BSS size comes from the 64k emergency buffer that my c++
		142	compiler allocates (but of course doesn't use unless you are out of
		143	memory). Also, using an xft font instead of a core font immediately adds a
		144	few megabytes of RSS. Xft indeed is responsible for a lot of RSS even when
		145	not used.
		146
		147	Of course, due to every character using two or four bytes instead of one,
		148	a large scrollback buffer will ultimately make rxvt-unicode use more
		149	memory.
		150
		151	Compared to e.g. Eterm (5112k), aterm (3132k) and xterm (4680k), this
		152	still fares rather well. And compared to some monsters like gnome-terminal
		153	(21152k + extra 4204k in separate processes) or konsole (22200k + extra
		154	43180k in daemons that stay around after exit, plus half a minute of
		155	startup time, including the hundreds of warnings it spits out), it fares
		156	extremely well *g*.
		157
		158	=head3 Why C++, isn't that unportable/bloated/uncool?
		159
		160	Is this a question? :) It comes up very often. The simple answer is: I had
		161	to write it, and C++ allowed me to write and maintain it in a fraction
		162	of the time and effort (which is a scarce resource for me). Put even
		163	shorter: It simply wouldn't exist without C++.
		164
		165	My personal stance on this is that C++ is less portable than C, but in
		166	the case of rxvt-unicode this hardly matters, as its portability limits
		167	are defined by things like X11, pseudo terminals, locale support and unix
		168	domain sockets, which are all less portable than C++ itself.
		169
		170	Regarding the bloat, see the above question: It's easy to write programs
		171	in C that use gobs of memory, an certainly possible to write programs in
		172	C++ that don't. C++ also often comes with large libraries, but this is
		173	not necessarily the case with GCC. Here is what rxvt links against on my
		174	system with a minimal config:
		175
		176	libX11.so.6 => /usr/X11R6/lib/libX11.so.6 (0x00002aaaaabc3000)
		177	libc.so.6 => /lib/libc.so.6 (0x00002aaaaadde000)
		178	libdl.so.2 => /lib/libdl.so.2 (0x00002aaaab01d000)
		179	/lib64/ld-linux-x86-64.so.2 (0x00002aaaaaaab000)
		180
		181	And here is rxvt-unicode:
		182
		183	libX11.so.6 => /usr/X11R6/lib/libX11.so.6 (0x00002aaaaabc3000)
		184	libgcc_s.so.1 => /lib/libgcc_s.so.1 (0x00002aaaaada2000)
		185	libc.so.6 => /lib/libc.so.6 (0x00002aaaaaeb0000)
		186	libdl.so.2 => /lib/libdl.so.2 (0x00002aaaab0ee000)
		187	/lib64/ld-linux-x86-64.so.2 (0x00002aaaaaaab000)
		188
		189	No large bloated libraries (of course, none were linked in statically),
		190	except maybe libX11 :)

		192
		193	=head2 Rendering, Font & Look and Feel Issues
		194
		195	=head3 I can't get transparency working, what am I doing wrong?
		196
		197	First of all, transparency isn't officially supported in rxvt-unicode, so
		198	you are mostly on your own. Do not bug the author about it (but you may
		199	bug everybody else). Also, if you can't get it working consider it a rite
		200	of passage: ... and you failed.
		201
		202	Here are four ways to get transparency. B<Do> read the manpage and option
		203	descriptions for the programs mentioned and rxvt-unicode. Really, do it!
		204
		205	1. Use inheritPixmap:
		206
		207	Esetroot wallpaper.jpg
		208	@@URXVT_NAME@@ -ip -tint red -sh 40
		209
		210	That works. If you think it doesn't, you lack transparency and tinting
		211	support, or you are unable to read.
		212
		213	2. Use a simple pixmap and emulate pseudo-transparency. This enables you
		214	to use effects other than tinting and shading: Just shade/tint/whatever
		215	your picture with gimp or any other tool:
		216
		217	convert wallpaper.jpg -blur 20x20 -modulate 30 background.xpm
		218	@@URXVT_NAME@@ -pixmap background.xpm -pe automove-background
		219
		220	That works. If you think it doesn't, you lack XPM and Perl support, or you
		221	are unable to read.
		222
		223	3. Use an ARGB visual:
		224
		225	@@URXVT_NAME@@ -depth 32 -fg grey90 -bg rgba:0000/0000/4444/cccc
		226
		227	This requires XFT support, and the support of your X-server. If that
		228	doesn't work for you, blame Xorg and Keith Packard. ARGB visuals aren't
		229	there yet, no matter what they claim. Rxvt-Unicode contains the neccessary
		230	bugfixes and workarounds for Xft and Xlib to make it work, but that
		231	doesn't mean that your WM has the required kludges in place.
		232
		233	4. Use xcompmgr and let it do the job:
		234
		235	xprop -frame -f _NET_WM_WINDOW_OPACITY 32c \
		236	-set _NET_WM_WINDOW_OPACITY 0xc0000000
		237
		238	Then click on a window you want to make transparent. Replace C<0xc0000000>
		239	by other values to change the degree of opacity. If it doesn't work and
		240	your server crashes, you got to keep the pieces.
		241
		242	=head3 Why do some chinese characters look so different than others?
		243
		244	This is because there is a difference between script and language --
		245	rxvt-unicode does not know which language the text that is output is,
		246	as it only knows the unicode character codes. If rxvt-unicode first
		247	sees a japanese/chinese character, it might choose a japanese font for
		248	display. Subsequent japanese characters will use that font. Now, many
		249	chinese characters aren't represented in japanese fonts, so when the first
		250	non-japanese character comes up, rxvt-unicode will look for a chinese font
		251	-- unfortunately at this point, it will still use the japanese font for
		252	chinese characters that are also in the japanese font.
		253
		254	The workaround is easy: just tag a chinese font at the end of your font
		255	list (see the previous question). The key is to view the font list as
		256	a preference list: If you expect more japanese, list a japanese font
		257	first. If you expect more chinese, put a chinese font first.
		258
		259	In the future it might be possible to switch language preferences at
		260	runtime (the internal data structure has no problem with using different
		261	fonts for the same character at the same time, but no interface for this
		262	has been designed yet).
		263
		264	Until then, you might get away with switching fonts at runtime (see L<Can
		265	I switch the fonts at runtime?> later in this document).
		266
		267	=head3 Why does rxvt-unicode sometimes leave pixel droppings?
		268
		269	Most fonts were not designed for terminal use, which means that character
		270	size varies a lot. A font that is otherwise fine for terminal use might
		271	contain some characters that are simply too wide. Rxvt-unicode will avoid
		272	these characters. For characters that are just "a bit" too wide a special
		273	"careful" rendering mode is used that redraws adjacent characters.
		274
		275	All of this requires that fonts do not lie about character sizes,
		276	however: Xft fonts often draw glyphs larger than their acclaimed bounding
		277	box, and rxvt-unicode has no way of detecting this (the correct way is to
		278	ask for the character bounding box, which unfortunately is wrong in these
		279	cases).
		280
		281	It's not clear (to me at least), wether this is a bug in Xft, freetype,
		282	or the respective font. If you encounter this problem you might try using
		283	the C<-lsp> option to give the font more height. If that doesn't work, you
		284	might be forced to use a different font.
		285
		286	All of this is not a problem when using X11 core fonts, as their bounding
		287	box data is correct.
		288
		289	=head3 How can I keep rxvt-unicode from using reverse video so much?
		290
		291	First of all, make sure you are running with the right terminal settings
		292	(C<TERM=rxvt-unicode>), which will get rid of most of these effects. Then
		293	make sure you have specified colours for italic and bold, as otherwise
		294	rxvt-unicode might use reverse video to simulate the effect:
		295
		296	URxvt.colorBD: white
		297	URxvt.colorIT: green
		298
		299	=head3 Some programs assume totally weird colours (red instead of blue), how can I fix that?
		300
		301	For some unexplainable reason, some rare programs assume a very weird
		302	colour palette when confronted with a terminal with more than the standard
		303	8 colours (rxvt-unicode supports 88). The right fix is, of course, to fix
		304	these programs not to assume non-ISO colours without very good reasons.
		305
		306	In the meantime, you can either edit your C<rxvt-unicode> terminfo
		307	definition to only claim 8 colour support or use C<TERM=rxvt>, which will
		308	fix colours but keep you from using other rxvt-unicode features.
		309
		310	=head3 Can I switch the fonts at runtime?
		311
		312	Yes, using an escape sequence. Try something like this, which has the same
		313	effect as using the C<-fn> switch, and takes effect immediately:
		314
		315	printf '\e]50;%s\007' "9x15bold,xft:Kochi Gothic"
		316
		317	This is useful if you e.g. work primarily with japanese (and prefer a
		318	japanese font), but you have to switch to chinese temporarily, where
		319	japanese fonts would only be in your way.
		320
		321	You can think of this as a kind of manual ISO-2022 switching.
		322
		323	=head3 Why do italic characters look as if clipped?
		324
		325	Many fonts have difficulties with italic characters and hinting. For
		326	example, the otherwise very nicely hinted font C<xft:Bitstream Vera Sans
		327	Mono> completely fails in it's italic face. A workaround might be to
		328	enable freetype autohinting, i.e. like this:
		329
		330	URxvt.italicFont: xft:Bitstream Vera Sans Mono:italic:autohint=true
		331	URxvt.boldItalicFont: xft:Bitstream Vera Sans Mono:bold:italic:autohint=true
		332
		333	=head3 Can I speed up Xft rendering somehow?
		334
		335	Yes, the most obvious way to speed it up is to avoid Xft entirely, as
		336	it is simply slow. If you still want Xft fonts you might try to disable
		337	antialiasing (by appending C<:antialias=false>), which saves lots of
		338	memory and also speeds up rendering considerably.
		339
		340	=head3 Rxvt-unicode doesn't seem to anti-alias its fonts, what is wrong?
		341
		342	Rxvt-unicode will use whatever you specify as a font. If it needs to
		343	fall back to it's default font search list it will prefer X11 core
		344	fonts, because they are small and fast, and then use Xft fonts. It has
		345	antialiasing disabled for most of them, because the author thinks they
		346	look best that way.
		347
		348	If you want antialiasing, you have to specify the fonts manually.
		349
		350	=head3 What's with this bold/blink stuff?
		351
		352	If no bold colour is set via C<colorBD:>, bold will invert text using the
		353	standard foreground colour.
		354
		355	For the standard background colour, blinking will actually make the
		356	text blink when compiled with C<--enable-blinking>. with standard
		357	colours. Without C<--enable-blinking>, the blink attribute will be
		358	ignored.
		359
		360	On ANSI colours, bold/blink attributes are used to set high-intensity
		361	foreground/background colors.
		362
		363	color0-7 are the low-intensity colors.
		364
		365	color8-15 are the corresponding high-intensity colors.
		366
		367	=head3 I don't like the screen colors. How do I change them?
		368
		369	You can change the screen colors at run-time using F<~/.Xdefaults>
		370	resources (or as long-options).
		371
		372	Here are values that are supposed to resemble a VGA screen,
		373	including the murky brown that passes for low-intensity yellow:
		374
		375	URxvt.color0: #000000
		376	URxvt.color1: #A80000
		377	URxvt.color2: #00A800
		378	URxvt.color3: #A8A800
		379	URxvt.color4: #0000A8
		380	URxvt.color5: #A800A8
		381	URxvt.color6: #00A8A8
		382	URxvt.color7: #A8A8A8
		383
		384	URxvt.color8: #000054
		385	URxvt.color9: #FF0054
		386	URxvt.color10: #00FF54
		387	URxvt.color11: #FFFF54
		388	URxvt.color12: #0000FF
		389	URxvt.color13: #FF00FF
		390	URxvt.color14: #00FFFF
		391	URxvt.color15: #FFFFFF
		392
		393	And here is a more complete set of non-standard colors described (not by
		394	me) as "pretty girly".
		395
		396	URxvt.cursorColor: #dc74d1
		397	URxvt.pointerColor: #dc74d1
		398	URxvt.background: #0e0e0e

		415	=head3 Why do some characters look so much different than others?
		416
		417	See next entry.
		418
		419	=head3 How does rxvt-unicode choose fonts?
		420
		421	Most fonts do not contain the full range of Unicode, which is
		422	fine. Chances are that the font you (or the admin/package maintainer of
		423	your system/os) have specified does not cover all the characters you want
		424	to display.
		425
		426	B<rxvt-unicode> makes a best-effort try at finding a replacement
		427	font. Often the result is fine, but sometimes the chosen font looks
		428	bad/ugly/wrong. Some fonts have totally strange characters that don't
		429	resemble the correct glyph at all, and rxvt-unicode lacks the artificial
		430	intelligence to detect that a specific glyph is wrong: it has to believe
		431	the font that the characters it claims to contain indeed look correct.
		432
		433	In that case, select a font of your taste and add it to the font list,
		434	e.g.:
		435
		436	@@URXVT_NAME@@ -fn basefont,font2,font3...
		437
		438	When rxvt-unicode sees a character, it will first look at the base
		439	font. If the base font does not contain the character, it will go to the
		440	next font, and so on. Specifying your own fonts will also speed up this
		441	search and use less resources within rxvt-unicode and the X-server.
		442
		443	The only limitation is that none of the fonts may be larger than the base
		444	font, as the base font defines the terminal character cell size, which
		445	must be the same due to the way terminals work.
		446
		447
		448	=head2 Keyboard, Mouse & User Interaction
		449
		450	=head3 The new selection selects pieces that are too big, how can I select single words?
		451
		452	If you want to select e.g. alphanumeric words, you can use the following
		453	setting:
		454
		455	URxvt.selection.pattern-0: ([[:word:]]+)
		456
		457	If you click more than twice, the selection will be extended
		458	more and more.
		459
		460	To get a selection that is very similar to the old code, try this pattern:
		461
		462	URxvt.selection.pattern-0: ([^"&'()*,;<=>?@[\\\\]^`{|})]+)
		463
		464	Please also note that the I<LeftClick Shift-LeftClik> combination also
		465	selects words like the old code.
		466
		467	=head3 I don't like the new selection/popups/hotkeys/perl, how do I change/disable it?
		468
		469	You can disable the perl extension completely by setting the
		470	B<perl-ext-common> resource to the empty string, which also keeps
		471	rxvt-unicode from initialising perl, saving memory.
		472
		473	If you only want to disable specific features, you first have to
		474	identify which perl extension is responsible. For this, read the section
		475	B<PREPACKAGED EXTENSIONS> in the @@URXVT_NAME@@perl(3) manpage. For
		476	example, to disable the B<selection-popup> and B<option-popup>, specify
		477	this B<perl-ext-common> resource:
		478
		479	URxvt.perl-ext-common: default,-selection-popup,-option-popup
		480
		481	This will keep the default extensions, but disable the two popup
		482	extensions. Some extensions can also be configured, for example,
		483	scrollback search mode is triggered by B<M-s>. You can move it to any
		484	other combination either by setting the B<searchable-scrollback> resource:
		485
		486	URxvt.searchable-scrollback: CM-s
		487
		488	=head3 The cursor moves when selecting text in the current input line, how do I switch this off?
		489
		490	See next entry.
		491
		492	=head3 During rlogin/ssh/telnet/etc. sessions, clicking near the cursor outputs strange escape sequences, how do I fix this?
		493
		494	These are caused by the C<readline> perl extension. Under normal
		495	circumstances, it will move your cursor around when you click into the
		496	line that contains it. It tries hard not to do this at the wrong moment,
		497	but when running a program that doesn't parse cursor movements or in some
		498	cases during rlogin sessions, it fails to detect this properly.
		499
		500	You can permamently switch this feature off by disabling the C<readline>
		501	extension:
		502
		503	URxvt.perl-ext-common: default,-readline
		504
		505	=head3 My numerical keypad acts weird and generates differing output?
		506
		507	Some Debian GNUL/Linux users seem to have this problem, although no
		508	specific details were reported so far. It is possible that this is caused
		509	by the wrong C<TERM> setting, although the details of wether and how
		510	this can happen are unknown, as C<TERM=rxvt> should offer a compatible
		511	keymap. See the answer to the previous question, and please report if that
		512	helped.
		513
		514	=head3 My Compose (Multi_key) key is no longer working.
		515
		516	The most common causes for this are that either your locale is not set
		517	correctly, or you specified a B<preeditStyle> that is not supported by
		518	your input method. For example, if you specified B<OverTheSpot> and
		519	your input method (e.g. the default input method handling Compose keys)
		520	does not support this (for instance because it is not visual), then
		521	rxvt-unicode will continue without an input method.
		522
		523	In this case either do not specify a B<preeditStyle> or specify more than
		524	one pre-edit style, such as B<OverTheSpot,Root,None>.
		525
		526	=head3 I cannot type C<Ctrl-Shift-2> to get an ASCII NUL character due to ISO 14755
		527
		528	Either try C<Ctrl-2> alone (it often is mapped to ASCII NUL even on
		529	international keyboards) or simply use ISO 14755 support to your
		530	advantage, typing <Ctrl-Shift-0> to get a ASCII NUL. This works for other
		531	codes, too, such as C<Ctrl-Shift-1-d> to type the default telnet escape
		532	character and so on.
		533
		534	=head3 Mouse cut/paste suddenly no longer works.
		535
		536	Make sure that mouse reporting is actually turned off since killing
		537	some editors prematurely may leave the mouse in mouse report mode. I've
		538	heard that tcsh may use mouse reporting unless it otherwise specified. A
		539	quick check is to see if cut/paste works when the Alt or Shift keys are
		540	depressed.
		541
		542	=head3 What's with the strange Backspace/Delete key behaviour?
		543
		544	Assuming that the physical Backspace key corresponds to the
		545	BackSpace keysym (not likely for Linux ... see the following
		546	question) there are two standard values that can be used for
		547	Backspace: C<^H> and C<^?>.
		548
		549	Historically, either value is correct, but rxvt-unicode adopts the debian
		550	policy of using C<^?> when unsure, because it's the one only only correct
		551	choice :).
		552
		553	Rxvt-unicode tries to inherit the current stty settings and uses the value
		554	of `erase' to guess the value for backspace. If rxvt-unicode wasn't
		555	started from a terminal (say, from a menu or by remote shell), then the
		556	system value of `erase', which corresponds to CERASE in <termios.h>, will
		557	be used (which may not be the same as your stty setting).
		558
		559	For starting a new rxvt-unicode:
		560
		561	# use Backspace = ^H
		562	$ stty erase ^H
		563	$ @@URXVT_NAME@@
		564
		565	# use Backspace = ^?
		566	$ stty erase ^?
		567	$ @@URXVT_NAME@@
		568
		569	Toggle with C<ESC [ 36 h> / C<ESC [ 36 l>.
		570
		571	For an existing rxvt-unicode:
		572
		573	# use Backspace = ^H
		574	$ stty erase ^H
		575	$ echo -n "^[[36h"
		576
		577	# use Backspace = ^?
		578	$ stty erase ^?
		579	$ echo -n "^[[36l"
		580
		581	This helps satisfy some of the Backspace discrepancies that occur, but
		582	if you use Backspace = C<^H>, make sure that the termcap/terminfo value
		583	properly reflects that.
		584
		585	The Delete key is a another casualty of the ill-defined Backspace problem.
		586	To avoid confusion between the Backspace and Delete keys, the Delete
		587	key has been assigned an escape sequence to match the vt100 for Execute
		588	(C<ESC [ 3 ~>) and is in the supplied termcap/terminfo.
		589
		590	Some other Backspace problems:
		591
		592	some editors use termcap/terminfo,
		593	some editors (vim I'm told) expect Backspace = ^H,
		594	GNU Emacs (and Emacs-like editors) use ^H for help.
		595
		596	Perhaps someday this will all be resolved in a consistent manner.
		597
		598	=head3 I don't like the key-bindings. How do I change them?
		599
		600	There are some compile-time selections available via configure. Unless
		601	you have run "configure" with the C<--disable-resources> option you can
		602	use the `keysym' resource to alter the keystrings associated with keysyms.
		603
		604	Here's an example for a URxvt session started using C<@@URXVT_NAME@@ -name URxvt>

		627	See some more examples in the documentation for the B<keysym> resource.
		628
		629	=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
		630
		631	KP_Insert == Insert
		632	F22 == Print
		633	F27 == Home
		634	F29 == Prior
		635	F33 == End
		636	F35 == Next
		637
		638	Rather than have rxvt-unicode try to accommodate all the various possible
		639	keyboard mappings, it is better to use `xmodmap' to remap the keys as
		640	required for your particular machine.

		643
		644	=head2 Terminal Configuration
		645
		646	=head3 Why doesn't rxvt-unicode read my resources?
		647
		648	Well, why, indeed? It does, in a way very similar to other X
		649	applications. Most importantly, this means that if you or your OS loads
		650	resources into the X display (the right way to do it), rxvt-unicode will
		651	ignore any resource files in your home directory. It will only read
		652	F<$HOME/.Xdefaults> when no resources are attached to the display.
		653
		654	If you have or use an F<$HOME/.Xresources> file, chances are that
		655	resources are loaded into your X-server. In this case, you have to
		656	re-login after every change (or run F<xrdb -merge $HOME/.Xresources>).
		657
		658	Also consider the form resources have to use:
		659
		660	URxvt.resource: value
		661
		662	If you want to use another form (there are lots of different ways of
		663	specifying resources), make sure you understand wether and why it
		664	works. If unsure, use the form above.

198	resemble the correct glyph at all, and rxvt-unicode lacks the artificial

202	In that case, select a font of your taste and add it to the font list,	820	The reasons is that there exists a perfectly fine mechanism for selecting

210	search and use less resources within rxvt-unicode and the X-server.
211
212	The only limitation is that none of the fonts may be larger than the base
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).	826	locales).
254		827
255	It's not clear (to me at least), wether this is a bug in Xft, freetype,	828	Rxvt-unicode uses the C<LC_CTYPE> locale category to select encoding. All
256	or the respective font. If you encounter this problem you might try using	829	programs doing the same (that is, most) will automatically agree in the

258	might be forced to use a different font.
259		831
260	All of this is not a problem when using X11 core fonts, as their bounding	832	Unfortunately, there is no system-independent way to select locales, nor
261	box data is correct.	833	is there a standard on how locale specifiers will look like.
262		834
		835	On most systems, the content of the C<LC_CTYPE> environment variable
		836	contains an arbitrary string which corresponds to an already-installed
		837	locale. Common names for locales are C<en_US.UTF-8>, C<de_DE.ISO-8859-15>,
		838	C<ja_JP.EUC-JP>, i.e. C<language_country.encoding>, but other forms
		839	(i.e. C<de> or C<german>) are also common.
		840
		841	Rxvt-unicode ignores all other locale categories, and except for
		842	the encoding, ignores country or language-specific settings,
		843	i.e. C<de_DE.UTF-8> and C<ja_JP.UTF-8> are the normally same to
		844	rxvt-unicode.
		845
		846	If you want to use a specific encoding you have to make sure you start
		847	rxvt-unicode with the correct C<LC_CTYPE> category.
		848
		849	=head3 Can I switch locales at runtime?
		850
		851	Yes, using an escape sequence. Try something like this, which sets
		852	rxvt-unicode's idea of C<LC_CTYPE>.
		853
		854	printf '\e]701;%s\007' ja_JP.SJIS
		855
		856	See also the previous answer.
		857
		858	Sometimes this capability is rather handy when you want to work in
		859	one locale (e.g. C<de_DE.UTF-8>) but some programs don't support it
		860	(e.g. UTF-8). For example, I use this script to start C<xjdic>, which
		861	first switches to a locale supported by xjdic and back later:
		862
		863	printf '\e]701;%s\007' ja_JP.SJIS
		864	xjdic -js
		865	printf '\e]701;%s\007' de_DE.UTF-8
		866
		867	You can also use xterm's C<luit> program, which usually works fine, except
		868	for some locales where character width differs between program- and
		869	rxvt-unicode-locales.
		870
		871	=head3 My input method wants <some encoding> but I want UTF-8, what can I do?
		872
		873	You can specify separate locales for the input method and the rest of the
		874	terminal, using the resource C<imlocale>:
		875
		876	URxvt.imlocale: ja_JP.EUC-JP
		877
		878	Now you can start your terminal with C<LC_CTYPE=ja_JP.UTF-8> and still
		879	use your input method. Please note, however, that you will not be able to
		880	input characters outside C<EUC-JP> in a normal way then, as your input
		881	method limits you.
		882
		883	=head3 Rxvt-unicode crashes when the X Input Method changes or exits.
		884
		885	Unfortunately, this is unavoidable, as the XIM protocol is racy by
		886	design. Applications can avoid some crashes at the expense of memory
		887	leaks, and Input Methods can avoid some crashes by careful ordering at
		888	exit time. B<kinput2> (and derived input methods) generally succeeds,
		889	while B<SCIM> (or similar input methods) fails. In the end, however,
		890	crashes cannot be completely avoided even if both sides cooperate.
		891
		892	So the only workaround is not to kill your Input Method Servers.

		894
		895	=head2 Operating Systems / Package Maintaining
		896
		897	=head3 I am using Debian GNU/Linux and have a problem...
		898
		899	The Debian GNU/Linux package of rxvt-unicode in sarge contains large
		900	patches that considerably change the behaviour of rxvt-unicode (but
		901	unfortunately this notice has been removed). Before reporting a bug to
		902	the original rxvt-unicode author please download and install the genuine
		903	version (L<http://software.schmorp.de#rxvt-unicode>) and try to reproduce
		904	the problem. If you cannot, chances are that the problems are specific to
		905	Debian GNU/Linux, in which case it should be reported via the Debian Bug
		906	Tracking System (use C<reportbug> to report the bug).
		907
		908	For other problems that also affect the Debian package, you can and
		909	probably should use the Debian BTS, too, because, after all, it's also a
		910	bug in the Debian version and it serves as a reminder for other users that
		911	might encounter the same issue.
		912
		913	=head3 I am maintaining rxvt-unicode for distribution/OS XXX, any recommendation?
		914
		915	You should build one binary with the default options. F<configure>
		916	now enables most useful options, and the trend goes to making them
		917	runtime-switchable, too, so there is usually no drawback to enbaling them,
		918	except higher disk and possibly memory usage. The perl interpreter should
		919	be enabled, as important functionality (menus, selection, likely more in
		920	the future) depends on it.
		921
		922	You should not overwrite the C<perl-ext-common> snd C<perl-ext> resources
		923	system-wide (except maybe with C<defaults>). This will result in useful
		924	behaviour. If your distribution aims at low memory, add an empty
		925	C<perl-ext-common> resource to the app-defaults file. This will keep the
		926	perl interpreter disabled until the user enables it.
		927
		928	If you can/want build more binaries, I recommend building a minimal
		929	one with C<--disable-everything> (very useful) and a maximal one with
		930	C<--enable-everything> (less useful, it will be very big due to a lot of
		931	encodings built-in that increase download times and are rarely used).
		932
		933	=head3 I need to make it setuid/setgid to support utmp/ptys on my OS, is this safe?
		934
		935	It should be, starting with release 7.1. You are encouraged to properly
		936	install urxvt with privileges necessary for your OS now.
		937
		938	When rxvt-unicode detects that it runs setuid or setgid, it will fork
		939	into a helper process for privileged operations (pty handling on some
		940	systems, utmp/wtmp/lastlog handling on others) and drop privileges
		941	immediately. This is much safer than most other terminals that keep
		942	privileges while running (but is more relevant to urxvt, as it contains
		943	things as perl interpreters, which might be "helpful" to attackers).
		944
		945	This forking is done as the very first within main(), which is very early
		946	and reduces possible bugs to initialisation code run before main(), or
		947	things like the dynamic loader of your system, which should result in very
		948	little risk.

271	=item My Compose (Multi_key) key is no longer working.
272
273	The most common causes for this are that either your locale is not set
274	correctly, or you specified a B<preeditStyle> that is not supported by
275	your input method. For example, if you specified B<OverTheSpot> and
276	your input method (e.g. the default input method handling Compose keys)
277	does not support this (for instance because it is not visual), then
278	rxvt-unicode will continue without an input method.
279
280	In this case either do not specify a B<preeditStyle> or specify more than
281	one pre-edit style, such as B<OverTheSpot,Root,None>.
282
283	=item I cannot type C<Ctrl-Shift-2> to get an ASCII NUL character due to ISO 14755

285	Either try C<Ctrl-2> alone (it often is mapped to ASCII NUL even on

288	codes, too, such as C<Ctrl-Shift-1-d> to type the default telnet escape
289	character and so on.
290

292
293	First of all, make sure you are running with the right terminal settings
294	(C<TERM=rxvt-unicode>), which will get rid of most of these effects. Then
295	make sure you have specified colours for italic and bold, as otherwise
296	rxvt-unicode might use reverse video to simulate the effect:
297
298	URxvt.colorBD: white
299	URxvt.colorIT: green
300
301	=item Some programs assume totally weird colours (red instead of blue), how can I fix that?
302
303	For some unexplainable reason, some rare programs assume a very weird
304	colour palette when confronted with a terminal with more than the standard
305	8 colours (rxvt-unicode supports 88). The right fix is, of course, to fix
306	these programs not to assume non-ISO colours without very good reasons.
307
308	In the meantime, you can either edit your C<rxvt-unicode> terminfo
309	definition to only claim 8 colour support or use C<TERM=rxvt>, which will
310	fix colours but keep you from using other rxvt-unicode features.

361	=item How does rxvt-unicode determine the encoding to use?
362
363	=item Is there an option to switch encodings?
364
365	Unlike some other terminals, rxvt-unicode has no encoding switch, and no
366	specific "utf-8" mode, such as xterm. In fact, it doesn't even know about
367	UTF-8 or any other encodings with respect to terminal I/O.
368
369	The reasons is that there exists a perfectly fine mechanism for selecting
370	the encoding, doing I/O and (most important) communicating this to all
371	applications so everybody agrees on character properties such as width
372	and code number. This mechanism is the I<locale>. Applications not using
373	that info will have problems (for example, C<xterm> gets the width of
374	characters wrong as it uses it's own, locale-independent table under all
375	locales).
376
377	Rxvt-unicode uses the C<LC_CTYPE> locale category to select encoding. All
378	programs doing the same (that is, most) will automatically agree in the
379	interpretation of characters.
380
381	Unfortunately, there is no system-independent way to select locales, nor
382	is there a standard on how locale specifiers will look like.
383
384	On most systems, the content of the C<LC_CTYPE> environment variable
385	contains an arbitrary string which corresponds to an already-installed
386	locale. Common names for locales are C<en_US.UTF-8>, C<de_DE.ISO-8859-15>,
387	C<ja_JP.EUC-JP>, i.e. C<language_country.encoding>, but other forms
388	(i.e. C<de> or C<german>) are also common.
389
390	Rxvt-unicode ignores all other locale categories, and except for
391	the encoding, ignores country or language-specific settings,
392	i.e. C<de_DE.UTF-8> and C<ja_JP.UTF-8> are the normally same to
393	rxvt-unicode.
394
395	If you want to use a specific encoding you have to make sure you start
396	rxvt-unicode with the correct C<LC_CTYPE> category.
397
398	=item Can I switch locales at runtime?
399
400	Yes, using an escape sequence. Try something like this, which sets

408	one locale (e.g. C<de_DE.UTF-8>) but some programs don't support it
409	(e.g. UTF-8). For example, I use this script to start C<xjdic>, which
410	first switches to a locale supported by xjdic and back later:
411
412	printf '\e]701;%s\007' ja_JP.SJIS
413	xjdic -js
414	printf '\e]701;%s\007' de_DE.UTF-8
415
416	You can also use xterm's C<luit> program, which usually works fine, except
417	for some locales where character width differs between program- and
418	rxvt-unicode-locales.
419
420	=item Can I switch the fonts at runtime?
421
422	Yes, using an escape sequence. Try something like this, which has the same
423	effect as using the C<-fn> switch, and takes effect immediately:
424
425	printf '\e]50;%s\007' "9x15bold,xft:Kochi Gothic"
426
427	This is useful if you e.g. work primarily with japanese (and prefer a
428	japanese font), but you have to switch to chinese temporarily, where
429	japanese fonts would only be in your way.
430
431	You can think of this as a kind of manual ISO-2022 switching.
432
433	=item Why do italic characters look as if clipped?
434
435	Many fonts have difficulties with italic characters and hinting. For
436	example, the otherwise very nicely hinted font C<xft:Bitstream Vera Sans
437	Mono> completely fails in it's italic face. A workaround might be to
438	enable freetype autohinting, i.e. like this:
439
440	URxvt.italicFont: xft:Bitstream Vera Sans Mono:italic:autohint=true
441	URxvt.boldItalicFont: xft:Bitstream Vera Sans Mono:bold:italic:autohint=true
442
443	=item My input method wants <some encoding> but I want UTF-8, what can I do?
444
445	You can specify separate locales for the input method and the rest of the
446	terminal, using the resource C<imlocale>:
447
448	URxvt*imlocale: ja_JP.EUC-JP
449
450	Now you can start your terminal with C<LC_CTYPE=ja_JP.UTF-8> and still
451	use your input method. Please note, however, that you will not be able to
452	input characters outside C<EUC-JP> in a normal way then, as your input
453	method limits you.
454
455	=item Rxvt-unicode crashes when the X Input Method changes or exits.
456
457	Unfortunately, this is unavoidable, as the XIM protocol is racy by
458	design. Applications can avoid some crashes at the expense of memory
459	leaks, and Input Methods can avoid some crashes by careful ordering at
460	exit time. B<kinput2> (and derived input methods) generally succeeds,
461	while B<SCIM> (or similar input methods) fails. In the end, however,
462	crashes cannot be completely avoided even if both sides cooperate.
463
464	So the only workaround is not to kill your Input Method Servers.
465
466	=item Rxvt-unicode uses gobs of memory, how can I reduce that?
467
468	Rxvt-unicode tries to obey the rule of not charging you for something you
469	don't use. One thing you should try is to configure out all settings that
470	you don't need, for example, Xft support is a resource hog by design,
471	when used. Compiling it out ensures that no Xft font will be loaded
472	accidentally when rxvt-unicode tries to find a font for your characters.
473
474	Also, many people (me included) like large windows and even larger
475	scrollback buffers: Without C<--enable-unicode3>, rxvt-unicode will use
476	6 bytes per screen cell. For a 160x?? window this amounts to almost a
477	kilobyte per line. A scrollback buffer of 10000 lines will then (if full)
478	use 10 Megabytes of memory. With C<--enable-unicode3> it gets worse, as
479	rxvt-unicode then uses 8 bytes per screen cell.
480
481	=item Can I speed up Xft rendering somehow?
482
483	Yes, the most obvious way to speed it up is to avoid Xft entirely, as
484	it is simply slow. If you still want Xft fonts you might try to disable
485	antialiasing (by appending C<:antialiasing=false>), which saves lots of
486	memory and also speeds up rendering considerably.
487
488	=item Rxvt-unicode doesn't seem to anti-alias its fonts, what is wrong?
489
490	Rxvt-unicode will use whatever you specify as a font. If it needs to
491	fall back to it's default font search list it will prefer X11 core
492	fonts, because they are small and fast, and then use Xft fonts. It has
493	antialiasing disabled for most of them, because the author thinks they
494	look best that way.
495
496	If you want antialiasing, you have to specify the fonts manually.
497
498	=item Mouse cut/paste suddenly no longer works.
499
500	Make sure that mouse reporting is actually turned off since killing
501	some editors prematurely may leave the mouse in mouse report mode. I've
502	heard that tcsh may use mouse reporting unless it otherwise specified. A
503	quick check is to see if cut/paste works when the Alt or Shift keys are
504	depressed. See @@RXVT_NAME@@(7)
505
506	=item What's with this bold/blink stuff?
507
508	If no bold colour is set via C<colorBD:>, bold will invert text using the
509	standard foreground colour.
510
511	For the standard background colour, blinking will actually make the
512	text blink when compiled with C<--enable-blinking>. with standard
513	colours. Without C<--enable-blinking>, the blink attribute will be
514	ignored.
515
516	On ANSI colours, bold/blink attributes are used to set high-intensity
517	foreground/background colors.
518
519	color0-7 are the low-intensity colors.
520
521	color8-15 are the corresponding high-intensity colors.
522
523	=item I don't like the screen colors. How do I change them?
524
525	You can change the screen colors at run-time using F<~/.Xdefaults>
526	resources (or as long-options).
527
528	Here are values that are supposed to resemble a VGA screen,
529	including the murky brown that passes for low-intensity yellow:

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

669	=item I'm using keyboard model XXX that has extra Prior/Next/Insert keys.
670	How do I make use of them? For example, the Sun Keyboard type 4

675	F27 == Home
676	F29 == Prior
677	F33 == End
678	F35 == Next
679
680	Rather than have rxvt-unicode try to accommodate all the various possible
681	keyboard mappings, it is better to use `xmodmap' to remap the keys as

684	=item How do I distinguish wether I'm running rxvt-unicode or a regular xterm?
685	I need this to decide about setting colors etc.
686
687	rxvt and rxvt-unicode always export the variable "COLORTERM", so you can
688	check and see if that is set. Note that several programs, JED, slrn,
689	Midnight Commander automatically check this variable to decide whether or
690	not to use color.

692	=item How do I set the correct, full IP address for the DISPLAY variable?
693
694	If you've compiled rxvt-unicode with DISPLAY_IS_IP and have enabled
695	insecure mode then it is possible to use the following shell script
696	snippets to correctly set the display. If your version of rxvt-unicode
697	wasn't also compiled with ESCZ_ANSWER (as assumed in these snippets) then
698	the COLORTERM variable can be used to distinguish rxvt-unicode from a
699	regular xterm.

1539	=head2 Overview of menuBar operation
1540
1541	For the menuBar XTerm escape sequence C<ESC ] 703 ; Pt ST>, the syntax
1542	of C<Pt> can be used for a variety of tasks:
1543
1544	At the top level is the current menuBar which is a member of a circular
1545	linked-list of other such menuBars.
1546
1547	The menuBar acts as a parent for the various drop-down menus, which in
1548	turn, may have labels, separator lines, menuItems and subMenus.
1549
1550	The menuItems are the useful bits: you can use them to mimic keyboard
1551	input or even to send text or escape sequences back to rxvt.
1552
1553	The menuBar syntax is intended to provide a simple yet robust method of
1554	constructing and manipulating menus and navigating through the
1555	menuBars.
1556
1557	The first step is to use the tag B<< [menu:I<name>] >> which creates
1558	the menuBar called I<name> and allows access. You may now or menus,
1559	subMenus, and menuItems. Finally, use the tag B<[done]> to set the
1560	menuBar access as B<readonly> to prevent accidental corruption of the
1561	menus. To re-access the current menuBar for alterations, use the tag
1562	B<[menu]>, make the alterations and then use B<[done]>
