		28	=item The new selection selects pieces that are too big, how can I select
		29	single words?
		30
		31	Yes. For example, if you want to select alphanumeric words, you can use
		32	the following resource:
		33
		34	URxvt.selection.pattern-0: ([[:word:]]+)
		35
		36	If you click more than twice, the selection will be extended
		37	more and more.
		38
		39	To get a selection that is very similar to the old code, try this pattern:
		40
		41	URxvt.selection.pattern-0: ([^"&'()*,;<=>?@[\\\\]^`{|})]+)
		42
		43	Please also note that the I<LeftClick Shift-LeftClik> combination also
		44	selects words like the old code.
		45
		46	=item I don't like the new selection/popups/hotkeys/perl, how do I
		47	change/disable it?
		48
		49	You can disable the perl extension completely by setting the
		50	B<perl-ext-common> resource to the empty string, which also keeps
		51	rxvt-unicode from initialising perl, saving memory.
		52
		53	If you only want to disable specific features, you first have to
		54	identify which perl extension is responsible. For this, read the section
		55	B<PREPACKAGED EXTENSIONS> in the @@RXVT_NAME@@perl(3) manpage. For
		56	example, to disable the B<selection-popup> and B<option-popup>, specify
		57	this B<perl-ext-common> resource:
		58
		59	URxvt.perl-ext-common: default,-selection-popup,-option-popup
		60
		61	This will keep the default extensions, but disable the two popup
		62	extensions. Some extensions can also be configured, for example,
		63	scrollback search mode is triggered by B<M-s>. You can move it to any
		64	other combination either by setting the B<searchable-scrollback> resource:
		65
		66	URxvt.searchable-scrollback: CM-s
		67
		68	=item Why doesn't rxvt-unicode read my resources?
		69
		70	Well, why, indeed? It does, in a way very similar to other X
		71	applications. Most importantly, this means that if you or your OS loads
		72	resources into the X display (the right way to do it), rxvt-unicode will
		73	ignore any resource files in your home directory. It will only read
		74	F<$HOME/.Xdefaults> when no resources are attached to the display.
		75
		76	If you have or use an F<$HOME/.Xresources> file, chances are that
		77	resources are loaded into your X-server. In this case, you have to
		78	re-login after every change (or run F<xrdb -merge $HOME/.Xresources>).
		79
		80	Also consider the form resources have to use:
		81
		82	URxvt.resource: value
		83
		84	If you want to use another form (there are lots of different ways of
		85	specifying resources), make sure you understand wether and why it
		86	works. If unsure, use the form above.
		87
		88	=item I can't get transparency working, what am I doing wrong?
		89
		90	First of all, transparency isn't officially supported in rxvt-unicode, so
		91	you are mostly on your own. Do not bug the author about it (but you may
		92	bug everybody else). Also, if you can't get it working consider it a rite
		93	of passage: ... and you failed.
		94
		95	Here are four ways to get transparency. B<Do> read the manpage and option
		96	descriptions for the programs mentioned and rxvt-unicode. Really, do it!
		97
		98	1. Use inheritPixmap:
		99
		100	Esetroot wallpaper.jpg
		101	@@RXVT_NAME@@ -ip -tint red -sh 40
		102
		103	That works. If you think it doesn't, you lack transparency and tinting
		104	support, or you are unable to read.
		105
		106	2. Use a simple pixmap and emulate pseudo-transparency. This enables you
		107	to use effects other than tinting and shading: Just shade/tint/whatever
		108	your picture with gimp:
		109
		110	convert wallpaper.jpg -blur 20x20 -modulate 30 background.xpm
		111	@@RXVT_NAME@@ -pixmap background.xpm -pe automove-background
		112
		113	That works. If you think it doesn't, you lack XPM and Perl support, or you
		114	are unable to read.
		115
		116	3. Use an ARGB visual:
		117
		118	@@RXVT_NAME@@ -depth 32 -fg grey90 -bg rgba:0000/0000/4444/cccc
		119
		120	This requires XFT support, and the support of your X-server. If that
		121	doesn't work for you, blame Xorg and Keith Packard. ARGB visuals aren't
		122	there yet, no matter what they claim. Rxvt-Unicode contains the neccessary
		123	bugfixes and workarounds for Xft and Xlib to make it work, but that
		124	doesn't mean that your WM has the required kludges in place.
		125
		126	4. Use xcompmgr and let it do the job:
		127
		128	xprop -frame -f _NET_WM_WINDOW_OPACITY 32c \
		129	-set _NET_WM_WINDOW_OPACITY 0xc0000000
		130
		131	Then click on a window you want to make transparent. Replace C<0xc0000000>
		132	by other values to change the degree of opacity. If it doesn't work and
		133	your server crashes, you got to keep the pieces.
		134
		135	=item Isn't rxvt supposed to be small? Don't all those features bloat?
		136
		137	I often get asked about this, and I think, no, they didn't cause extra
		138	bloat. If you compare a minimal rxvt and a minimal urxvt, you can see
		139	that the urxvt binary is larger (due to some encoding tables always being
		140	compiled in), but it actually uses less memory (RSS) after startup. Even
		141	with C<--disable-everything>, this comparison is a bit unfair, as many
		142	features unique to urxvt (locale, encoding conversion, iso14755 etc.) are
		143	already in use in this mode.
		144
		145	text data bss drs rss filename
		146	98398 1664 24 15695 1824 rxvt --disable-everything
		147	188985 9048 66616 18222 1788 urxvt --disable-everything
		148
		149	When you C<--enable-everything> (which _is_ unfair, as this involves xft
		150	and full locale/XIM support which are quite bloaty inside libX11 and my
		151	libc), the two diverge, but not unreasnobaly so.
		152
		153	text data bss drs rss filename
		154	163431 2152 24 20123 2060 rxvt --enable-everything
		155	1035683 49680 66648 29096 3680 urxvt --enable-everything
		156
		157	The very large size of the text section is explained by the east-asian
		158	encoding tables, which, if unused, take up disk space but nothing else
		159	and can be compiled out unless you rely on X11 core fonts that use those
		160	encodings. The BSS size comes from the 64k emergency buffer that my c++
		161	compiler allocates (but of course doesn't use unless you are out of
		162	memory). Also, using an xft font instead of a core font immediately adds a
		163	few megabytes of RSS. Xft indeed is responsible for a lot of RSS even when
		164	not used.
		165
		166	Of course, due to every character using two or four bytes instead of one,
		167	a large scrollback buffer will ultimately make rxvt-unicode use more
		168	memory.
		169
		170	Compared to e.g. Eterm (5112k), aterm (3132k) and xterm (4680k), this
		171	still fares rather well. And compared to some monsters like gnome-terminal
		172	(21152k + extra 4204k in separate processes) or konsole (22200k + extra
		173	43180k in daemons that stay around after exit, plus half a minute of
		174	startup time, including the hundreds of warnings it spits out), it fares
		175	extremely well *g*.
		176
		177	=item Why C++, isn't that unportable/bloated/uncool?
		178
		179	Is this a question? :) It comes up very often. The simple answer is: I had
		180	to write it, and C++ allowed me to write and maintain it in a fraction
		181	of the time and effort (which is a scarce resource for me). Put even
		182	shorter: It simply wouldn't exist without C++.
		183
		184	My personal stance on this is that C++ is less portable than C, but in
		185	the case of rxvt-unicode this hardly matters, as its portability limits
		186	are defined by things like X11, pseudo terminals, locale support and unix
		187	domain sockets, which are all less portable than C++ itself.
		188
		189	Regarding the bloat, see the above question: It's easy to write programs
		190	in C that use gobs of memory, an certainly possible to write programs in
		191	C++ that don't. C++ also often comes with large libraries, but this is
		192	not necessarily the case with GCC. Here is what rxvt links against on my
		193	system with a minimal config:
		194
		195	libX11.so.6 => /usr/X11R6/lib/libX11.so.6 (0x00002aaaaabc3000)
		196	libc.so.6 => /lib/libc.so.6 (0x00002aaaaadde000)
		197	libdl.so.2 => /lib/libdl.so.2 (0x00002aaaab01d000)
		198	/lib64/ld-linux-x86-64.so.2 (0x00002aaaaaaab000)
		199
		200	And here is rxvt-unicode:
		201
		202	libX11.so.6 => /usr/X11R6/lib/libX11.so.6 (0x00002aaaaabc3000)
		203	libgcc_s.so.1 => /lib/libgcc_s.so.1 (0x00002aaaaada2000)
		204	libc.so.6 => /lib/libc.so.6 (0x00002aaaaaeb0000)
		205	libdl.so.2 => /lib/libdl.so.2 (0x00002aaaab0ee000)
		206	/lib64/ld-linux-x86-64.so.2 (0x00002aaaaaaab000)
		207
		208	No large bloated libraries (of course, none were linked in statically),
		209	except maybe libX11 :)
		210
		211	=item Does it support tabs, can I have a tabbed rxvt-unicode?
		212
		213	Beginning with version 7.3, there is a perl extension that implements a
		214	simple tabbed terminal. It is installed by default, so any of these should
		215	give you tabs:
		216
		217	@@RXVT_NAME@@ -pe tabbed
		218
		219	URxvt.perl-ext-common: default,tabbed
		220
		221	It will also work fine with tabbing functionality of many window managers
		222	or similar tabbing programs, and its embedding-features allow it to be
		223	embedded into other programs, as witnessed by F<doc/rxvt-tabbed> or
		224	the upcoming C<Gtk2::URxvt> perl module, which features a tabbed urxvt
		225	(murxvt) terminal as an example embedding application.

		249
		250	=item I am maintaining rxvt-unicode for distribution/OS XXX, any
		251	recommendation?
		252
		253	You should build one binary with the default options. F<configure>
		254	now enables most useful options, and the trend goes to making them
		255	runtime-switchable, too, so there is usually no drawback to enbaling them,
		256	except higher disk and possibly memory usage. The perl interpreter should
		257	be enabled, as important functionality (menus, selection, likely more in
		258	the future) depends on it.
		259
		260	You should not overwrite the C<perl-ext-common> snd C<perl-ext> resources
		261	system-wide (except maybe with C<defaults>). This will result in useful
		262	behaviour. If your distribution aims at low memory, add an empty
		263	C<perl-ext-common> resource to the app-defaults file. This will keep the
		264	perl interpreter disabled until the user enables it.
		265
		266	If you can/want build more binaries, I recommend building a minimal
		267	one with C<--disable-everything> (very useful) and a maximal one with
		268	C<--enable-everything> (less useful, it will be very big due to a lot of
		269	encodings built-in that increase download times and are rarely used).
		270
		271	=item I need to make it setuid/setgid to support utmp/ptys on my OS, is this safe?
		272
		273	It should be, starting with release 7.1. You are encouraged to properly
		274	install urxvt with privileges necessary for your OS now.
		275
		276	When rxvt-unicode detects that it runs setuid or setgid, it will fork
		277	into a helper process for privileged operations (pty handling on some
		278	systems, utmp/wtmp/lastlog handling on others) and drop privileges
		279	immediately. This is much safer than most other terminals that keep
		280	privileges while running (but is more relevant to urxvt, as it contains
		281	things as perl interpreters, which might be "helpful" to attackers).
		282
		283	This forking is done as the very first within main(), which is very early
		284	and reduces possible bugs to initialisation code run before main(), or
		285	things like the dynamic loader of your system, which should result in very
		286	little risk.

1497	=head2 Overview of menuBar operation
1498
1499	For the menuBar XTerm escape sequence C<ESC ] 703 ; Pt ST>, the syntax
1500	of C<Pt> can be used for a variety of tasks:
1501
1502	At the top level is the current menuBar which is a member of a circular
1503	linked-list of other such menuBars.
1504
1505	The menuBar acts as a parent for the various drop-down menus, which in
1506	turn, may have labels, separator lines, menuItems and subMenus.
1507
1508	The menuItems are the useful bits: you can use them to mimic keyboard
1509	input or even to send text or escape sequences back to rxvt.
1510
1511	The menuBar syntax is intended to provide a simple yet robust method of
1512	constructing and manipulating menus and navigating through the
1513	menuBars.
1514
1515	The first step is to use the tag B<< [menu:I<name>] >> which creates
1516	the menuBar called I<name> and allows access. You may now or menus,
1517	subMenus, and menuItems. Finally, use the tag B<[done]> to set the
1518	menuBar access as B<readonly> to prevent accidental corruption of the
1519	menus. To re-access the current menuBar for alterations, use the tag
1520	B<[menu]>, make the alterations and then use B<[done]>
