		9	There are three big problems with Gentoo Linux: first of all, most if
		10	not all Gentoo systems are completely broken (missing or mismatched
		11	header files, broken compiler etc. are just the tip of the iceberg);
		12	secondly, the Gentoo maintainer thinks it is a good idea to add broken
		13	patches to the code; and lastly, it should be called Gentoo GNU/Linux.

10	and more.	16	Problems appearing on Gentoo systems will usually simply be ignored
		17	unless they can be reproduced on non-Gentoo systems.
11		18
12	To get a selection that is very similar to the old code, try this
13	pattern:
14
15	URxvt.selection.pattern-0: ([^"&'()*,;<=>?@[\\\\]^`{|})]+)
16
17	Please also note that the *LeftClick Shift-LeftClik* combination
18	also selects words like the old code.
19
20	I don't like the new selection/popups/hotkeys/perl, how do I
21	change/disable it?
22	You can disable the perl extension completely by setting the
23	perl-ext-common resource to the empty string, which also keeps
24	rxvt-unicode from initialising perl, saving memory.
25
26	If you only want to disable specific features, you first have to
27	identify which perl extension is responsible. For this, read the
28	section PREPACKAGED EXTENSIONS in the rxvtperl(3) manpage. For
29	example, to disable the selection-popup and option-popup, specify
30	this perl-ext-common resource:
31
32	URxvt.perl-ext-common: default,-selection-popup,-option-popup
33
34	This will keep the default extensions, but disable the two popup
35	extensions. Some extensions can also be configured, for example,
36	scrollback search mode is triggered by M-s. You can move it to any
37	other combination either by setting the searchable-scrollback
38	resource:
39
40	URxvt.searchable-scrollback: CM-s
41
42	Isn't rxvt supposed to be small? Don't all those features bloat?
43	I often get asked about this, and I think, no, they didn't cause
44	extra bloat. If you compare a minimal rxvt and a minimal urxvt, you
45	can see that the urxvt binary is larger (due to some encoding tables
46	always being compiled in), but it actually uses less memory (RSS)
47	after startup. Even with "--disable-everything", this comparison is
48	a bit unfair, as many features unique to urxvt (locale, encoding
49	conversion, iso14755 etc.) are already in use in this mode.
50
51	text data bss drs rss filename
52	98398 1664 24 15695 1824 rxvt --disable-everything
53	188985 9048 66616 18222 1788 urxvt --disable-everything
54
55	When you "--enable-everything" (which _is_ unfair, as this involves
56	xft and full locale/XIM support which are quite bloaty inside libX11
57	and my libc), the two diverge, but not unreasnobaly so.
58
59	text data bss drs rss filename
60	163431 2152 24 20123 2060 rxvt --enable-everything
61	1035683 49680 66648 29096 3680 urxvt --enable-everything
62
63	The very large size of the text section is explained by the
64	east-asian encoding tables, which, if unused, take up disk space but
65	nothing else and can be compiled out unless you rely on X11 core
66	fonts that use those encodings. The BSS size comes from the 64k
67	emergency buffer that my c++ compiler allocates (but of course
68	doesn't use unless you are out of memory). Also, using an xft font
69	instead of a core font immediately adds a few megabytes of RSS. Xft
70	indeed is responsible for a lot of RSS even when not used.
71
72	Of course, due to every character using two or four bytes instead of
73	one, a large scrollback buffer will ultimately make rxvt-unicode use
74	more memory.
75
76	Compared to e.g. Eterm (5112k), aterm (3132k) and xterm (4680k),
77	this still fares rather well. And compared to some monsters like
78	gnome-terminal (21152k + extra 4204k in separate processes) or
79	konsole (22200k + extra 43180k in daemons that stay around after
80	exit, plus half a minute of startup time, including the hundreds of
81	warnings it spits out), it fares extremely well *g*.
82
83	Why C++, isn't that unportable/bloated/uncool?
84	Is this a question? :) It comes up very often. The simple answer is:
85	I had to write it, and C++ allowed me to write and maintain it in a
86	fraction of the time and effort (which is a scarce resource for me).
87	Put even shorter: It simply wouldn't exist without C++.
88
89	My personal stance on this is that C++ is less portable than C, but
90	in the case of rxvt-unicode this hardly matters, as its portability
91	limits are defined by things like X11, pseudo terminals, locale
92	support and unix domain sockets, which are all less portable than
93	C++ itself.
94
95	Regarding the bloat, see the above question: It's easy to write
96	programs in C that use gobs of memory, an certainly possible to
97	write programs in C++ that don't. C++ also often comes with large
98	libraries, but this is not necessarily the case with GCC. Here is
99	what rxvt links against on my system with a minimal config:
100
101	libX11.so.6 => /usr/X11R6/lib/libX11.so.6 (0x00002aaaaabc3000)
102	libc.so.6 => /lib/libc.so.6 (0x00002aaaaadde000)
103	libdl.so.2 => /lib/libdl.so.2 (0x00002aaaab01d000)
104	/lib64/ld-linux-x86-64.so.2 (0x00002aaaaaaab000)
105
106	And here is rxvt-unicode:
107
108	libX11.so.6 => /usr/X11R6/lib/libX11.so.6 (0x00002aaaaabc3000)
109	libgcc_s.so.1 => /lib/libgcc_s.so.1 (0x00002aaaaada2000)
110	libc.so.6 => /lib/libc.so.6 (0x00002aaaaaeb0000)

		182
		183	Rendering, Font & Look and Feel Issues
		184	I can't get transparency working, what am I doing wrong?
		185	First of all, please address all transparency related issues to Sasha
		186	Vasko at sasha@aftercode.net and do not bug the author about it. Also,
		187	if you can't get it working consider it a rite of passage: ... and you
		188	failed.
		189
		190	Here are four ways to get transparency. Do read the manpage and option
		191	descriptions for the programs mentioned and rxvt-unicode. Really, do it!
		192
		193	1. Use transparent mode:
		194
		195	Esetroot wallpaper.jpg
		196	urxvt -tr -tint red -sh 40
		197
		198	That works. If you think it doesn't, you lack transparency and tinting
		199	support, or you are unable to read.
		200
		201	2. Use a simple pixmap and emulate pseudo-transparency. This enables you
		202	to use effects other than tinting and shading: Just shade/tint/whatever
		203	your picture with gimp or any other tool:
		204
		205	convert wallpaper.jpg -blur 20x20 -modulate 30 background.jpg
		206	urxvt -pixmap "background.jpg;:root"
		207
		208	That works. If you think it doesn't, you lack AfterImage support, or you
		209	are unable to read.
		210
		211	3. Use an ARGB visual:
		212
		213	urxvt -depth 32 -fg grey90 -bg rgba:0000/0000/4444/cccc
		214
		215	This requires XFT support, and the support of your X-server. If that
		216	doesn't work for you, blame Xorg and Keith Packard. ARGB visuals aren't
		217	there yet, no matter what they claim. Rxvt-Unicode contains the
		218	necessary bugfixes and workarounds for Xft and Xlib to make it work, but
		219	that doesn't mean that your WM has the required kludges in place.
		220
		221	4. Use xcompmgr and let it do the job:
		222
		223	xprop -frame -f _NET_WM_WINDOW_OPACITY 32c \
		224	-set _NET_WM_WINDOW_OPACITY 0xc0000000
		225
		226	Then click on a window you want to make transparent. Replace 0xc0000000
		227	by other values to change the degree of opacity. If it doesn't work and
		228	your server crashes, you got to keep the pieces.
		229
		230	Why does rxvt-unicode sometimes leave pixel droppings?
		231	Most fonts were not designed for terminal use, which means that
		232	character size varies a lot. A font that is otherwise fine for terminal
		233	use might contain some characters that are simply too wide. Rxvt-unicode
		234	will avoid these characters. For characters that are just "a bit" too
		235	wide a special "careful" rendering mode is used that redraws adjacent
		236	characters.
		237
		238	All of this requires that fonts do not lie about character sizes,
		239	however: Xft fonts often draw glyphs larger than their acclaimed
		240	bounding box, and rxvt-unicode has no way of detecting this (the correct
		241	way is to ask for the character bounding box, which unfortunately is
		242	wrong in these cases).
		243
		244	It's not clear (to me at least), whether this is a bug in Xft, freetype,
		245	or the respective font. If you encounter this problem you might try
		246	using the "-lsp" option to give the font more height. If that doesn't
		247	work, you might be forced to use a different font.
		248
		249	All of this is not a problem when using X11 core fonts, as their
		250	bounding box data is correct.
		251
		252	How can I keep rxvt-unicode from using reverse video so much?
		253	First of all, make sure you are running with the right terminal settings
		254	("TERM=rxvt-unicode"), which will get rid of most of these effects. Then
		255	make sure you have specified colours for italic and bold, as otherwise
		256	rxvt-unicode might use reverse video to simulate the effect:
		257
		258	URxvt.colorBD: white
		259	URxvt.colorIT: green
		260
		261	Some programs assume totally weird colours (red instead of blue), how can I fix that?
		262	For some unexplainable reason, some rare programs assume a very weird
		263	colour palette when confronted with a terminal with more than the
		264	standard 8 colours (rxvt-unicode supports 88). The right fix is, of
		265	course, to fix these programs not to assume non-ISO colours without very
		266	good reasons.
		267
		268	In the meantime, you can either edit your "rxvt-unicode" terminfo
		269	definition to only claim 8 colour support or use "TERM=rxvt", which will
		270	fix colours but keep you from using other rxvt-unicode features.
		271
		272	Can I switch the fonts at runtime?
		273	Yes, using an escape sequence. Try something like this, which has the
		274	same effect as using the "-fn" switch, and takes effect immediately:
		275
		276	printf '\33]50;%s\007' "9x15bold,xft:Kochi Gothic"
		277
		278	This is useful if you e.g. work primarily with japanese (and prefer a
		279	japanese font), but you have to switch to chinese temporarily, where
		280	japanese fonts would only be in your way.
		281
		282	You can think of this as a kind of manual ISO-2022 switching.
		283
		284	Why do italic characters look as if clipped?
		285	Many fonts have difficulties with italic characters and hinting. For
		286	example, the otherwise very nicely hinted font "xft:Bitstream Vera Sans
		287	Mono" completely fails in its italic face. A workaround might be to
		288	enable freetype autohinting, i.e. like this:
		289
		290	URxvt.italicFont: xft:Bitstream Vera Sans Mono:italic:autohint=true
		291	URxvt.boldItalicFont: xft:Bitstream Vera Sans Mono:bold:italic:autohint=true
		292
		293	Can I speed up Xft rendering somehow?
		294	Yes, the most obvious way to speed it up is to avoid Xft entirely, as it
		295	is simply slow. If you still want Xft fonts you might try to disable
		296	antialiasing (by appending ":antialias=false"), which saves lots of
		297	memory and also speeds up rendering considerably.
		298
		299	Rxvt-unicode doesn't seem to anti-alias its fonts, what is wrong?
		300	Rxvt-unicode will use whatever you specify as a font. If it needs to
		301	fall back to its default font search list it will prefer X11 core fonts,
		302	because they are small and fast, and then use Xft fonts. It has
		303	antialiasing disabled for most of them, because the author thinks they
		304	look best that way.
		305
		306	If you want antialiasing, you have to specify the fonts manually.
		307
		308	What's with this bold/blink stuff?
		309	If no bold colour is set via "colorBD:", bold will invert text using the
		310	standard foreground colour.
		311
		312	For the standard background colour, blinking will actually make the text
		313	blink when compiled with "--enable-text-blink". Without
		314	"--enable-text-blink", the blink attribute will be ignored.
		315
		316	On ANSI colours, bold/blink attributes are used to set high-intensity
		317	foreground/background colors.
		318
		319	color0-7 are the low-intensity colors.
		320
		321	color8-15 are the corresponding high-intensity colors.
		322
		323	I don't like the screen colors. How do I change them?
		324	You can change the screen colors at run-time using ~/.Xdefaults
		325	resources (or as long-options).
		326
		327	Here are values that are supposed to resemble a VGA screen, including
		328	the murky brown that passes for low-intensity yellow:
		329
		330	URxvt.color0: #000000
		331	URxvt.color1: #A80000
		332	URxvt.color2: #00A800
		333	URxvt.color3: #A8A800
		334	URxvt.color4: #0000A8
		335	URxvt.color5: #A800A8
		336	URxvt.color6: #00A8A8
		337	URxvt.color7: #A8A8A8
		338
		339	URxvt.color8: #000054
		340	URxvt.color9: #FF0054
		341	URxvt.color10: #00FF54
		342	URxvt.color11: #FFFF54
		343	URxvt.color12: #0000FF
		344	URxvt.color13: #FF00FF
		345	URxvt.color14: #00FFFF
		346	URxvt.color15: #FFFFFF
		347
		348	And here is a more complete set of non-standard colors.
		349
		350	URxvt.cursorColor: #dc74d1
		351	URxvt.pointerColor: #dc74d1
		352	URxvt.background: #0e0e0e
		353	URxvt.foreground: #4ad5e1
		354	URxvt.color0: #000000
		355	URxvt.color8: #8b8f93
		356	URxvt.color1: #dc74d1
		357	URxvt.color9: #dc74d1
		358	URxvt.color2: #0eb8c7
		359	URxvt.color10: #0eb8c7
		360	URxvt.color3: #dfe37e
		361	URxvt.color11: #dfe37e
		362	URxvt.color5: #9e88f0
		363	URxvt.color13: #9e88f0
		364	URxvt.color6: #73f7ff
		365	URxvt.color14: #73f7ff
		366	URxvt.color7: #e1dddd
		367	URxvt.color15: #e1dddd
		368
		369	They have been described (not by me) as "pretty girly".
		370
		371	Why do some characters look so much different than others?
		372	See next entry.
		373
		374	How does rxvt-unicode choose fonts?
		375	Most fonts do not contain the full range of Unicode, which is fine.
		376	Chances are that the font you (or the admin/package maintainer of your
		377	system/os) have specified does not cover all the characters you want to
		378	display.
		379
		380	rxvt-unicode makes a best-effort try at finding a replacement font.
		381	Often the result is fine, but sometimes the chosen font looks
		382	bad/ugly/wrong. Some fonts have totally strange characters that don't
		383	resemble the correct glyph at all, and rxvt-unicode lacks the artificial
		384	intelligence to detect that a specific glyph is wrong: it has to believe
		385	the font that the characters it claims to contain indeed look correct.
		386
		387	In that case, select a font of your taste and add it to the font list,
		388	e.g.:
		389
		390	urxvt -fn basefont,font2,font3...
		391
		392	When rxvt-unicode sees a character, it will first look at the base font.
		393	If the base font does not contain the character, it will go to the next
		394	font, and so on. Specifying your own fonts will also speed up this
		395	search and use less resources within rxvt-unicode and the X-server.
		396
		397	The only limitation is that none of the fonts may be larger than the
		398	base font, as the base font defines the terminal character cell size,
		399	which must be the same due to the way terminals work.
		400
		401	Why do some chinese characters look so different than others?
		402	This is because there is a difference between script and language --
		403	rxvt-unicode does not know which language the text that is output is, as
		404	it only knows the unicode character codes. If rxvt-unicode first sees a
		405	japanese/chinese character, it might choose a japanese font for display.
		406	Subsequent japanese characters will use that font. Now, many chinese
		407	characters aren't represented in japanese fonts, so when the first
		408	non-japanese character comes up, rxvt-unicode will look for a chinese
		409	font -- unfortunately at this point, it will still use the japanese font
		410	for chinese characters that are also in the japanese font.
		411
		412	The workaround is easy: just tag a chinese font at the end of your font
		413	list (see the previous question). The key is to view the font list as a
		414	preference list: If you expect more japanese, list a japanese font
		415	first. If you expect more chinese, put a chinese font first.
		416
		417	In the future it might be possible to switch language preferences at
		418	runtime (the internal data structure has no problem with using different
		419	fonts for the same character at the same time, but no interface for this
		420	has been designed yet).
		421
		422	Until then, you might get away with switching fonts at runtime (see "Can
		423	I switch the fonts at runtime?" later in this document).
		424
		425	How can I make mplayer display video correctly?
		426	We are working on it, in the meantime, as a workaround, use something
		427	like:
		428
		429	urxvt -b 600 -geometry 20x1 -e sh -c 'mplayer -wid $WINDOWID file...'
		430
		431	Keyboard, Mouse & User Interaction
		432	The new selection selects pieces that are too big, how can I select single words?
		433	If you want to select e.g. alphanumeric words, you can use the following
		434	setting:
		435
		436	URxvt.selection.pattern-0: ([[:word:]]+)
		437
		438	If you click more than twice, the selection will be extended more and
		439	more.
		440
		441	To get a selection that is very similar to the old code, try this
		442	pattern:
		443
		444	URxvt.selection.pattern-0: ([^"&'()*,;<=>?@[\\\\]^`{|})]+)
		445
		446	Please also note that the *LeftClick Shift-LeftClick* combination also
		447	selects words like the old code.
		448
		449	I don't like the new selection/popups/hotkeys/perl, how do I change/disable it?
		450	You can disable the perl extension completely by setting the
		451	perl-ext-common resource to the empty string, which also keeps
		452	rxvt-unicode from initialising perl, saving memory.
		453
		454	If you only want to disable specific features, you first have to
		455	identify which perl extension is responsible. For this, read the section
		456	PREPACKAGED EXTENSIONS in the urxvtperl(3) manpage. For example, to
		457	disable the selection-popup and option-popup, specify this
		458	perl-ext-common resource:
		459
		460	URxvt.perl-ext-common: default,-selection-popup,-option-popup
		461
		462	This will keep the default extensions, but disable the two popup
		463	extensions. Some extensions can also be configured, for example,
		464	scrollback search mode is triggered by M-s. You can move it to any other
		465	combination either by setting the searchable-scrollback resource:
		466
		467	URxvt.searchable-scrollback: CM-s
		468
		469	The cursor moves when selecting text in the current input line, how do I switch this off?
		470	See next entry.
		471
		472	During rlogin/ssh/telnet/etc. sessions, clicking near the cursor outputs strange escape sequences, how do I fix this?
		473	These are caused by the "readline" perl extension. Under normal
		474	circumstances, it will move your cursor around when you click into the
		475	line that contains it. It tries hard not to do this at the wrong moment,
		476	but when running a program that doesn't parse cursor movements or in
		477	some cases during rlogin sessions, it fails to detect this properly.
		478
		479	You can permanently switch this feature off by disabling the "readline"
		480	extension:
		481
		482	URxvt.perl-ext-common: default,-readline
		483
		484	My numerical keypad acts weird and generates differing output?
		485	Some Debian GNUL/Linux users seem to have this problem, although no
		486	specific details were reported so far. It is possible that this is
		487	caused by the wrong "TERM" setting, although the details of whether and
		488	how this can happen are unknown, as "TERM=rxvt" should offer a
		489	compatible keymap. See the answer to the previous question, and please
		490	report if that helped.
		491
		492	My Compose (Multi_key) key is no longer working.
		493	The most common causes for this are that either your locale is not set
		494	correctly, or you specified a preeditStyle that is not supported by your
		495	input method. For example, if you specified OverTheSpot and your input
		496	method (e.g. the default input method handling Compose keys) does not
		497	support this (for instance because it is not visual), then rxvt-unicode
		498	will continue without an input method.
		499
		500	In this case either do not specify a preeditStyle or specify more than
		501	one pre-edit style, such as OverTheSpot,Root,None.
		502
		503	If it still doesn't work, then maybe your input method doesn't support
		504	compose sequences - to fall back to the built-in one, make sure you
		505	don't specify an input method via "-im" or "XMODIFIERS".
		506
		507	I cannot type "Ctrl-Shift-2" to get an ASCII NUL character due to ISO 14755
		508	Either try "Ctrl-2" alone (it often is mapped to ASCII NUL even on
		509	international keyboards) or simply use ISO 14755 support to your
		510	advantage, typing <Ctrl-Shift-0> to get a ASCII NUL. This works for
		511	other codes, too, such as "Ctrl-Shift-1-d" to type the default telnet
		512	escape character and so on.
		513
		514	Mouse cut/paste suddenly no longer works.
		515	Make sure that mouse reporting is actually turned off since killing some
		516	editors prematurely may leave the mouse in mouse report mode. I've heard
		517	that tcsh may use mouse reporting unless it otherwise specified. A quick
		518	check is to see if cut/paste works when the Alt or Shift keys are
		519	depressed.
		520
		521	What's with the strange Backspace/Delete key behaviour?
		522	Assuming that the physical Backspace key corresponds to the Backspace
		523	keysym (not likely for Linux ... see the following question) there are
		524	two standard values that can be used for Backspace: "^H" and "^?".
		525
		526	Historically, either value is correct, but rxvt-unicode adopts the
		527	debian policy of using "^?" when unsure, because it's the one and only
		528	correct choice :).
		529
		530	Rxvt-unicode tries to inherit the current stty settings and uses the
		531	value of `erase' to guess the value for backspace. If rxvt-unicode
		532	wasn't started from a terminal (say, from a menu or by remote shell),
		533	then the system value of `erase', which corresponds to CERASE in
		534	<termios.h>, will be used (which may not be the same as your stty
		535	setting).
		536
		537	For starting a new rxvt-unicode:
		538
		539	# use Backspace = ^H
		540	$ stty erase ^H
		541	$ urxvt
		542
		543	# use Backspace = ^?
		544	$ stty erase ^?
		545	$ urxvt
		546
		547	Toggle with "ESC [ 36 h" / "ESC [ 36 l".
		548
		549	For an existing rxvt-unicode:
		550
		551	# use Backspace = ^H
		552	$ stty erase ^H
		553	$ echo -n "^[[36h"
		554
		555	# use Backspace = ^?
		556	$ stty erase ^?
		557	$ echo -n "^[[36l"
		558
		559	This helps satisfy some of the Backspace discrepancies that occur, but
		560	if you use Backspace = "^H", make sure that the termcap/terminfo value
		561	properly reflects that.
		562
		563	The Delete key is a another casualty of the ill-defined Backspace
		564	problem. To avoid confusion between the Backspace and Delete keys, the
		565	Delete key has been assigned an escape sequence to match the vt100 for
		566	Execute ("ESC [ 3 ~") and is in the supplied termcap/terminfo.
		567
		568	Some other Backspace problems:
		569
		570	some editors use termcap/terminfo, some editors (vim I'm told) expect
		571	Backspace = ^H, GNU Emacs (and Emacs-like editors) use ^H for help.
		572
		573	Perhaps someday this will all be resolved in a consistent manner.
		574
		575	I don't like the key-bindings. How do I change them?
		576	There are some compile-time selections available via configure. Unless
		577	you have run "configure" with the "--disable-resources" option you can
		578	use the `keysym' resource to alter the keystrings associated with
		579	keysyms.
		580
		581	Here's an example for a URxvt session started using "urxvt -name URxvt"
		582
		583	URxvt.keysym.Home: \033[1~
		584	URxvt.keysym.End: \033[4~
		585	URxvt.keysym.C-apostrophe: \033<C-'>
		586	URxvt.keysym.C-slash: \033<C-/>
		587	URxvt.keysym.C-semicolon: \033<C-;>
		588	URxvt.keysym.C-grave: \033<C-`>
		589	URxvt.keysym.C-comma: \033<C-,>
		590	URxvt.keysym.C-period: \033<C-.>
		591	URxvt.keysym.C-0x60: \033<C-`>
		592	URxvt.keysym.C-Tab: \033<C-Tab>
		593	URxvt.keysym.C-Return: \033<C-Return>
		594	URxvt.keysym.S-Return: \033<S-Return>
		595	URxvt.keysym.S-space: \033<S-Space>
		596	URxvt.keysym.M-Up: \033<M-Up>
		597	URxvt.keysym.M-Down: \033<M-Down>
		598	URxvt.keysym.M-Left: \033<M-Left>
		599	URxvt.keysym.M-Right: \033<M-Right>
		600	URxvt.keysym.M-C-0: list \033<M-C- 0123456789 >
		601	URxvt.keysym.M-C-a: list \033<M-C- abcdefghijklmnopqrstuvwxyz >
		602	URxvt.keysym.F12: command:\033]701;zh_CN.GBK\007
		603
		604	See some more examples in the documentation for the keysym resource.
		605
		606	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
		607	KP_Insert == Insert
		608	F22 == Print
		609	F27 == Home
		610	F29 == Prior
		611	F33 == End
		612	F35 == Next
		613
		614	Rather than have rxvt-unicode try to accommodate all the various
		615	possible keyboard mappings, it is better to use `xmodmap' to remap the
		616	keys as required for your particular machine.
		617
		618	Terminal Configuration
		619	Can I see a typical configuration?
		620	The default configuration tries to be xterm-like, which I don't like
		621	that much, but it's least surprise to regular users.
		622
		623	As a rxvt or rxvt-unicode user, you are practically supposed to invest
		624	time into customising your terminal. To get you started, here is the
		625	author's .Xdefaults entries, with comments on what they do. It's
		626	certainly not *typical*, but what's typical...
		627
		628	URxvt.cutchars: "()*,<>[]{}|'
		629	URxvt.print-pipe: cat >/tmp/xxx
		630
		631	These are just for testing stuff.
		632
		633	URxvt.imLocale: ja_JP.UTF-8
		634	URxvt.preeditType: OnTheSpot,None
		635
		636	This tells rxvt-unicode to use a special locale when communicating with
		637	the X Input Method, and also tells it to only use the OnTheSpot pre-edit
		638	type, which requires the "xim-onthespot" perl extension but rewards me
		639	with correct-looking fonts.
		640
		641	URxvt.perl-lib: /root/lib/urxvt
		642	URxvt.perl-ext-common: default,selection-autotransform,selection-pastebin,xim-onthespot,remote-clipboard
		643	URxvt.selection.pattern-0: ( at .*? line \\d+)
		644	URxvt.selection.pattern-1: ^(/[^:]+):\
		645	URxvt.selection-autotransform.0: s/^([^:[:space:]]+):(\\d+):?$/:e \\Q$1\\E\\x0d:$2\\x0d/
		646	URxvt.selection-autotransform.1: s/^ at (.*?) line (\\d+)$/:e \\Q$1\\E\\x0d:$2\\x0d/
		647
		648	This is my perl configuration. The first two set the perl library
		649	directory and also tells urxvt to use a large number of extensions. I
		650	develop for myself mostly, so I actually use most of the extensions I
		651	write.
		652
		653	The selection stuff mainly makes the selection perl-error-message aware
		654	and tells it to convert perl error messages into vi-commands to load the
		655	relevant file and go tot he error line number.
		656
		657	URxvt.scrollstyle: plain
		658	URxvt.secondaryScroll: true
		659
		660	As the documentation says: plain is the preferred scrollbar for the
		661	author. The "secondaryScroll" configures urxvt to scroll in full-screen
		662	apps, like screen, so lines scrolled out of screen end up in urxvt's
		663	scrollback buffer.
		664
		665	URxvt.background: #000000
		666	URxvt.foreground: gray90
		667	URxvt.color7: gray90
		668	URxvt.colorBD: #ffffff
		669	URxvt.cursorColor: #e0e080
		670	URxvt.throughColor: #8080f0
		671	URxvt.highlightColor: #f0f0f0
		672
		673	Some colours. Not sure which ones are being used or even non-defaults,
		674	but these are in my .Xdefaults. Most notably, they set
		675	foreground/background to light gray/black, and also make sure that the
		676	colour 7 matches the default foreground colour.
		677
		678	URxvt.underlineColor: yellow
		679
		680	Another colour, makes underline lines look different. Sometimes hurts,
		681	but is mostly a nice effect.

		721
		722	I wrote rxvt-unicode to be able to specify fonts exactly. So don't be
		723	overwhelmed. A special note: the "9x15bold" mentioned above is actually
		724	the version from XFree-3.3, as XFree-4 replaced it by a totally
		725	different font (different glyphs for ";" and many other harmless
		726	characters), while the second font is actually the "9x15bold" from
		727	XFree4/XOrg. The bold version has less chars than the medium version, so
		728	I use it for rare characters, too. When editing sources with vim, I use
		729	italic for comments and other stuff, which looks quite good with
		730	Bitstream Vera anti-aliased.
		731
		732	Terminus is a quite bad font (many very wrong glyphs), but for most of
		733	my purposes, it works, and gives a different look, as my normal
		734	(Non-bold) font is already bold, and I want to see a difference between
		735	bold and normal fonts.
		736
		737	Please note that I used the "urxvt" instance name and not the "URxvt"
		738	class name. Thats because I use different configs for different
		739	purposes, for example, my IRC window is started with "-name IRC", and
		740	uses these defaults:
		741
		742	IRC*title: IRC
		743	IRC*geometry: 87x12+535+542
		744	IRC*saveLines: 0
		745	IRC*mapAlert: true

		750	IRC*keysym.M-C-2: command:\033]710;9x15bold\007\033]711;9x15bold\007
		751
		752	"Alt-Ctrl-1" and "Alt-Ctrl-2" switch between two different font sizes.
		753	"suxuseuro" allows me to keep an eye (and actually read) stuff while
		754	keeping a very small window. If somebody pastes something complicated
		755	(e.g. japanese), I temporarily switch to a larger font.
		756
		757	The above is all in my ".Xdefaults" (I don't use ".Xresources" nor
		758	"xrdb"). I also have some resources in a separate ".Xdefaults-hostname"
		759	file for different hosts, for example, on ym main desktop, I use:
		760
		761	URxvt.keysym.C-M-q: command:\033[3;5;5t
		762	URxvt.keysym.C-M-y: command:\033[3;5;606t

		764	URxvt.keysym.C-M-c: command:\033[3;1605;606t
		765	URxvt.keysym.C-M-p: perl:test
		766
		767	The first for keysym definitions allow me to quickly bring some windows
		768	in the layout I like most. Ion users might start laughing but will stop
		769	immediately when I tell them that I use my own Fvwm2 module for much the
		770	same effect as Ion provides, and I only very rarely use the above key
		771	combinations :->
		772
		773	Why doesn't rxvt-unicode read my resources?
		774	Well, why, indeed? It does, in a way very similar to other X
		775	applications. Most importantly, this means that if you or your OS loads
		776	resources into the X display (the right way to do it), rxvt-unicode will
		777	ignore any resource files in your home directory. It will only read
		778	$HOME/.Xdefaults when no resources are attached to the display.
		779
		780	If you have or use an $HOME/.Xresources file, chances are that resources
		781	are loaded into your X-server. In this case, you have to re-login after
		782	every change (or run xrdb -merge $HOME/.Xresources).
		783
		784	Also consider the form resources have to use:
		785
		786	URxvt.resource: value
		787
		788	If you want to use another form (there are lots of different ways of
		789	specifying resources), make sure you understand whether and why it
		790	works. If unsure, use the form above.

323	Why do some characters look so much different than others?
324	How does rxvt-unicode choose fonts?
325	Most fonts do not contain the full range of Unicode, which is fine.
326	Chances are that the font you (or the admin/package maintainer of
327	your system/os) have specified does not cover all the characters you
328	want to display.
329
330	rxvt-unicode makes a best-effort try at finding a replacement font.
331	Often the result is fine, but sometimes the chosen font looks
332	bad/ugly/wrong. Some fonts have totally strange characters that
333	don't resemble the correct glyph at all, and rxvt-unicode lacks the
334	artificial intelligence to detect that a specific glyph is wrong: it
335	has to believe the font that the characters it claims to contain
336	indeed look correct.
337
338	In that case, select a font of your taste and add it to the font
339	list, e.g.:
340
341	rxvt -fn basefont,font2,font3...
342
343	When rxvt-unicode sees a character, it will first look at the base
344	font. If the base font does not contain the character, it will go to
345	the next font, and so on. Specifying your own fonts will also speed
346	up this search and use less resources within rxvt-unicode and the
347	X-server.
348
349	The only limitation is that none of the fonts may be larger than the
350	base font, as the base font defines the terminal character cell
351	size, which must be the same due to the way terminals work.
352
353	Why do some chinese characters look so different than others?
354	This is because there is a difference between script and language --
355	rxvt-unicode does not know which language the text that is output
356	is, as it only knows the unicode character codes. If rxvt-unicode
357	first sees a japanese/chinese character, it might choose a japanese
358	font for display. Subsequent japanese characters will use that font.
359	Now, many chinese characters aren't represented in japanese fonts,
360	so when the first non-japanese character comes up, rxvt-unicode will
361	look for a chinese font -- unfortunately at this point, it will
362	still use the japanese font for chinese characters that are also in
363	the japanese font.
364
365	The workaround is easy: just tag a chinese font at the end of your
366	font list (see the previous question). The key is to view the font
367	list as a preference list: If you expect more japanese, list a
368	japanese font first. If you expect more chinese, put a chinese font
369	first.
370
371	In the future it might be possible to switch language preferences at
372	runtime (the internal data structure has no problem with using
373	different fonts for the same character at the same time, but no
374	interface for this has been designed yet).
375
376	Until then, you might get away with switching fonts at runtime (see
377	"Can I switch the fonts at runtime?" later in this document).
378
379	Why does rxvt-unicode sometimes leave pixel droppings?
380	Most fonts were not designed for terminal use, which means that
381	character size varies a lot. A font that is otherwise fine for
382	terminal use might contain some characters that are simply too wide.
383	Rxvt-unicode will avoid these characters. For characters that are
384	just "a bit" too wide a special "careful" rendering mode is used
385	that redraws adjacent characters.
386
387	All of this requires that fonts do not lie about character sizes,
388	however: Xft fonts often draw glyphs larger than their acclaimed
389	bounding box, and rxvt-unicode has no way of detecting this (the
390	correct way is to ask for the character bounding box, which
391	unfortunately is wrong in these cases).
392
393	It's not clear (to me at least), wether this is a bug in Xft,
394	freetype, or the respective font. If you encounter this problem you
395	might try using the "-lsp" option to give the font more height. If
396	that doesn't work, you might be forced to use a different font.
397
398	All of this is not a problem when using X11 core fonts, as their
399	bounding box data is correct.
400
401	On Solaris 9, many line-drawing characters are too wide.
402	Seems to be a known bug, read
403	<http://nixdoc.net/files/forum/about34198.html>. Some people use the
404	following ugly workaround to get non-double-wide-characters working:
405
406	#define wcwidth(x) wcwidth(x) > 1 ? 1 : wcwidth(x)
407
408	My Compose (Multi_key) key is no longer working.
409	The most common causes for this are that either your locale is not
410	set correctly, or you specified a preeditStyle that is not supported
411	by your input method. For example, if you specified OverTheSpot and
412	your input method (e.g. the default input method handling Compose
413	keys) does not support this (for instance because it is not visual),
414	then rxvt-unicode will continue without an input method.
415
416	In this case either do not specify a preeditStyle or specify more
417	than one pre-edit style, such as OverTheSpot,Root,None.
418
419	I cannot type "Ctrl-Shift-2" to get an ASCII NUL character due to ISO
420	14755
421	Either try "Ctrl-2" alone (it often is mapped to ASCII NUL even on
422	international keyboards) or simply use ISO 14755 support to your
423	advantage, typing <Ctrl-Shift-0> to get a ASCII NUL. This works for
424	other codes, too, such as "Ctrl-Shift-1-d" to type the default
425	telnet escape character and so on.
426
427	How can I keep rxvt-unicode from using reverse video so much?
428	First of all, make sure you are running with the right terminal
429	settings ("TERM=rxvt-unicode"), which will get rid of most of these
430	effects. Then make sure you have specified colours for italic and
431	bold, as otherwise rxvt-unicode might use reverse video to simulate
432	the effect:
433
434	URxvt.colorBD: white
435	URxvt.colorIT: green
436
437	Some programs assume totally weird colours (red instead of blue), how
438	can I fix that?
439	For some unexplainable reason, some rare programs assume a very
440	weird colour palette when confronted with a terminal with more than
441	the standard 8 colours (rxvt-unicode supports 88). The right fix is,
442	of course, to fix these programs not to assume non-ISO colours
443	without very good reasons.
444
445	In the meantime, you can either edit your "rxvt-unicode" terminfo
446	definition to only claim 8 colour support or use "TERM=rxvt", which
447	will fix colours but keep you from using other rxvt-unicode
448	features.
449
450	I am on FreeBSD and rxvt-unicode does not seem to work at all.
451	Rxvt-unicode requires the symbol "__STDC_ISO_10646__" to be defined
452	in your compile environment, or an implementation that implements
453	it, wether it defines the symbol or not. "__STDC_ISO_10646__"
454	requires that wchar_t is represented as unicode.
455
456	As you might have guessed, FreeBSD does neither define this symobl
457	nor does it support it. Instead, it uses it's own internal
458	representation of wchar_t. This is, of course, completely fine with
459	respect to standards.
460
461	However, that means rxvt-unicode only works in "POSIX", "ISO-8859-1"
462	and "UTF-8" locales under FreeBSD (which all use Unicode as wchar_t.
463
464	"__STDC_ISO_10646__" is the only sane way to support multi-language
465	apps in an OS, as using a locale-dependent (and non-standardized)
466	representation of wchar_t makes it impossible to convert between
467	wchar_t (as used by X11 and your applications) and any other
468	encoding without implementing OS-specific-wrappers for each and
469	every locale. There simply are no APIs to convert wchar_t into
470	anything except the current locale encoding.
471
472	Some applications (such as the formidable mlterm) work around this
473	by carrying their own replacement functions for character set
474	handling with them, and either implementing OS-dependent hacks or
475	doing multiple conversions (which is slow and unreliable in case the
476	OS implements encodings slightly different than the terminal
477	emulator).
478
479	The rxvt-unicode author insists that the right way to fix this is in
480	the system libraries once and for all, instead of forcing every app
481	to carry complete replacements for them :)
482
483	I use Solaris 9 and it doesn't compile/work/etc.
484	Try the diff in doc/solaris9.patch as a base. It fixes the worst
485	problems with "wcwidth" and a compile problem.
486
487	How can I use rxvt-unicode under cygwin?
488	rxvt-unicode should compile and run out of the box on cygwin, using
489	the X11 libraries that come with cygwin. libW11 emulation is no
490	longer supported (and makes no sense, either, as it only supported a
491	single font). I recommend starting the X-server in "-multiwindow" or
492	"-rootless" mode instead, which will result in similar look&feel as
493	the old libW11 emulation.
494
495	At the time of this writing, cygwin didn't seem to support any
496	multi-byte encodings (you might try "LC_CTYPE=C-UTF-8"), so you are
497	likely limited to 8-bit encodings.

701	How can I start rxvtd in a race-free way?	1120	The solution is to upgrade your system or switch to a better one. A

705	What's with the strange Backspace/Delete key behaviour?	1123	http://www.cl.cam.ac.uk/~mgk25/ucs/wcwidth.c
706	Assuming that the physical Backspace key corresponds to the
707	BackSpace keysym (not likely for Linux ... see the following
708	question) there are two standard values that can be used for
709	Backspace: "^H" and "^?".
710		1124
711	Historically, either value is correct, but rxvt-unicode adopts the	1125	I want 256 colors
712	debian policy of using "^?" when unsure, because it's the one only	1126	Are you sure you need 256 colors? 88 colors should be enough for most
713	only correct choice :).	1127	purposes. If you really need more, there is an unsupported patch for it
		1128	in the doc directory, but please do not ask for it to be applied.
714		1129
715	Rxvt-unicode tries to inherit the current stty settings and uses the
716	value of `erase' to guess the value for backspace. If rxvt-unicode
717	wasn't started from a terminal (say, from a menu or by remote
718	shell), then the system value of `erase', which corresponds to
719	CERASE in <termios.h>, will be used (which may not be the same as
720	your stty setting).
721
722	For starting a new rxvt-unicode:
723
724	# use Backspace = ^H
725	$ stty erase ^H
726	$ rxvt
727
728	# use Backspace = ^?
729	$ stty erase ^?
730	$ rxvt
731
732	Toggle with "ESC [ 36 h" / "ESC [ 36 l".
733
734	For an existing rxvt-unicode:
735
736	# use Backspace = ^H
737	$ stty erase ^H
738	$ echo -n "^[[36h"
739
740	# use Backspace = ^?
741	$ stty erase ^?
742	$ echo -n "^[[36l"
743
744	This helps satisfy some of the Backspace discrepancies that occur,
745	but if you use Backspace = "^H", make sure that the termcap/terminfo
746	value properly reflects that.
747
748	The Delete key is a another casualty of the ill-defined Backspace
749	problem. To avoid confusion between the Backspace and Delete keys,
750	the Delete key has been assigned an escape sequence to match the
751	vt100 for Execute ("ESC [ 3 ~") and is in the supplied
752	termcap/terminfo.
753
754	Some other Backspace problems:
755
756	some editors use termcap/terminfo, some editors (vim I'm told)
757	expect Backspace = ^H, GNU Emacs (and Emacs-like editors) use ^H for
758	help.
759
760	Perhaps someday this will all be resolved in a consistent manner.
761
762	I don't like the key-bindings. How do I change them?
763	There are some compile-time selections available via configure.
764	Unless you have run "configure" with the "--disable-resources"
765	option you can use the `keysym' resource to alter the keystrings
766	associated with keysyms.
767
768	Here's an example for a URxvt session started using "rxvt -name
769	URxvt"
770
771	URxvt.keysym.Home: \033[1~
772	URxvt.keysym.End: \033[4~
773	URxvt.keysym.C-apostrophe: \033<C-'>
774	URxvt.keysym.C-slash: \033<C-/>

788	URxvt.keysym.M-C-0: list \033<M-C- 0123456789 >
789	URxvt.keysym.M-C-a: list \033<M-C- abcdefghijklmnopqrstuvwxyz >
790	URxvt.keysym.F12: command:\033]701;zh_CN.GBK\007
791
792	See some more examples in the documentation for the keysym resource.
793
794	I'm using keyboard model XXX that has extra Prior/Next/Insert keys. How
795	do I make use of them? For example, the Sun Keyboard type 4 has the
796	following mappings that rxvt-unicode doesn't recognize.
797	KP_Insert == Insert
798	F22 == Print
799	F27 == Home
800	F29 == Prior
801	F33 == End
802	F35 == Next
803
804	Rather than have rxvt-unicode try to accommodate all the various
805	possible keyboard mappings, it is better to use `xmodmap' to remap
806	the keys as required for your particular machine.
807
808	How do I distinguish wether I'm running rxvt-unicode or a regular xterm?
809	I need this to decide about setting colors etc.
810	rxvt and rxvt-unicode always export the variable "COLORTERM", so you
811	can check and see if that is set. Note that several programs, JED,
812	slrn, Midnight Commander automatically check this variable to decide
813	whether or not to use color.
814
815	How do I set the correct, full IP address for the DISPLAY variable?
816	If you've compiled rxvt-unicode with DISPLAY_IS_IP and have enabled
817	insecure mode then it is possible to use the following shell script
818	snippets to correctly set the display. If your version of
819	rxvt-unicode wasn't also compiled with ESCZ_ANSWER (as assumed in
820	these snippets) then the COLORTERM variable can be used to
821	distinguish rxvt-unicode from a regular xterm.
822
823	Courtesy of Chuck Blake <cblake@BBN.COM> with the following shell
824	script snippets:
825
826	# Bourne/Korn/POSIX family of shells:
827	[ ${TERM:-foo} = foo ] && TERM=xterm # assume an xterm if we don't know
828	if [ ${TERM:-foo} = xterm ]; then
829	stty -icanon -echo min 0 time 15 # see if enhanced rxvt or not
830	echo -n '^[Z'
831	read term_id
832	stty icanon echo
833	if [ ""${term_id} = '^[[?1;2C' -a ${DISPLAY:-foo} = foo ]; then
834	echo -n '^[[7n' # query the rxvt we are in for the DISPLAY string
835	read DISPLAY # set it in our local shell
836	fi
837	fi
838
839	How do I compile the manual pages for myself?
840	You need to have a recent version of perl installed as
841	/usr/bin/perl, one that comes with pod2man, pod2text and pod2html.
842	Then go to the doc subdirectory and enter "make alldoc".
843
844	My question isn't answered here, can I ask a human?
845	Before sending me mail, you could go to IRC: "irc.freenode.net",
846	channel "#rxvt-unicode" has some rxvt-unicode enthusiasts that might
847	be interested in learning about new and exciting problems (but not
848	FAQs :).
