48		56
		57	A double-click usually selects the word under the cursor, further clicks
		58	will enlarge the selection.
		59
		60	The selection works by trying to match a number of regexes and displaying
		61	them in increasing order of length. You can add your own regexes by
		62	specifying resources of the form:
		63
		64	URxvt.selection.pattern-0: perl-regex
		65	URxvt.selection.pattern-1: perl-regex
		66	...
		67
		68	The index number (0, 1...) must not have any holes, and each regex must
		69	contain at least one pair of capturing parentheses, which will be used for
		70	the match. For example, the following adds a regex that matches everything
		71	between two vertical bars:
		72
		73	URxvt.selection.pattern-0: \\|([^|]+)\\|
		74
		75	Another example: Programs I use often output "absolute path: " at the
		76	beginning of a line when they process multiple files. The following
		77	pattern matches the filename (note, there is a single space at the very
		78	end):
		79
		80	URxvt.selection.pattern-0: ^(/[^:]+):\
		81
		82	You can look at the source of the selection extension to see more
		83	interesting uses, such as parsing a line from beginning to end.

		157	selection if the C<Shift> modifier is active.
82		158
83	=item digital-clock	159	The regex defaults to "(?i)", resulting in a case-insensitive search. To
		160	get a case-sensitive search you can delete this prefix using C<BackSpace>
		161	or simply use an uppercase character which removes the "(?i)" prefix.
84		162
85	Displays a digital clock using the built-in overlay.	163	See L<perlre> for more info about perl regular expression syntax.
86		164
87	=item mark-urls	165	=item readline (enabled by default)
88		166
		167	A support package that tries to make editing with readline easier. At
		168	the moment, it reacts to clicking shift-left mouse button by trying to
		169	move the text cursor to this position. It does so by generating as many
		170	cursor-left or cursor-right keypresses as required (this only works
		171	for programs that correctly support wide characters).
		172
		173	To avoid too many false positives, this is only done when:
		174
		175	=over 4
		176
		177	=item - the tty is in ICANON state.
		178
		179	=item - the text cursor is visible.
		180
		181	=item - the primary screen is currently being displayed.
		182
		183	=item - the mouse is on the same (multi-row-) line as the text cursor.
		184
		185	=back
		186
		187	The normal selection mechanism isn't disabled, so quick successive clicks
		188	might interfere with selection creation in harmless ways.
		189
		190	=item selection-autotransform
		191
		192	This selection allows you to do automatic transforms on a selection
		193	whenever a selection is made.
		194
		195	It works by specifying perl snippets (most useful is a single C<s///>
		196	operator) that modify C<$_> as resources:
		197
		198	URxvt.selection-autotransform.0: transform
		199	URxvt.selection-autotransform.1: transform
		200	...
		201
		202	For example, the following will transform selections of the form
		203	C<filename:number>, often seen in compiler messages, into C<vi +$filename
		204	$word>:
		205
		206	URxvt.selection-autotransform.0: s/^([^:[:space:]]+):(\\d+):?$/vi +$2 \\Q$1\\E\\x0d/
		207
		208	And this example matches the same,but replaces it with vi-commands you can
		209	paste directly into your (vi :) editor:
		210
		211	URxvt.selection-autotransform.0: s/^([^:[:space:]]+(\\d+):?$/:e \\Q$1\\E\\x0d:$2\\x0d/
		212
		213	Of course, this can be modified to suit your needs and your editor :)
		214
		215	To expand the example above to typical perl error messages ("XXX at
		216	FILENAME line YYY."), you need a slightly more elaborate solution:
		217
		218	URxvt.selection.pattern-0: ( at .*? line \\d+[,.])
		219	URxvt.selection-autotransform.0: s/^ at (.*?) line (\\d+)[,.]$/:e \\Q$1\E\\x0d:$2\\x0d/
		220
		221	The first line tells the selection code to treat the unchanging part of
		222	every error message as a selection pattern, and the second line transforms
		223	the message into vi commands to load the file.
		224
		225	=item tabbed
		226
		227	This transforms the terminal into a tabbar with additional terminals, that
		228	is, it implements what is commonly referred to as "tabbed terminal". The topmost line
		229	displays a "[NEW]" button, which, when clicked, will add a new tab, followed by one
		230	button per tab.
		231
		232	Clicking a button will activate that tab. Pressing B<Shift-Left> and
		233	B<Shift-Right> will switch to the tab left or right of the current one,
		234	while B<Shift-Down> creates a new tab.
		235
		236	The tabbar itself can be configured similarly to a normal terminal, but
		237	with a resource class of C<URxvt.tabbed>. In addition, it supports the
		238	following four resources (shown with defaults):
		239
		240	URxvt.tabbed.tabbar-fg: <colour-index, default 3>
		241	URxvt.tabbed.tabbar-bg: <colour-index, default 0>
		242	URxvt.tabbed.tab-fg: <colour-index, default 0>
		243	URxvt.tabbed.tab-bg: <colour-index, default 1>
		244
		245	See I<COLOR AND GRAPHICS> in the @@RXVT_NAME@@(1) manpage for valid
		246	indices.
		247
		248	=item matcher
		249
89	Uses per-line display filtering (C<on_line_update>) to underline urls.	250	Uses per-line display filtering (C<on_line_update>) to underline text
		251	matching a certain pattern and make it clickable. When clicked with the
		252	mouse button specified in the C<matcher.button> resource (default 2, or
		253	middle), the program specified in the C<matcher.launcher> resource
		254	(default, the C<urlLauncher> resource, C<sensible-browser>) will be started
		255	with the matched text as first argument. The default configuration is
		256	suitable for matching URLs and launching a web browser, like the
		257	former "mark-urls" extension.
		258
		259	The default pattern to match URLs can be overridden with the
		260	C<matcher.pattern.0> resource, and additional patterns can be specified
		261	with numbered patterns, in a manner similar to the "selection" extension.
		262	The launcher can also be overridden on a per-pattern basis.
		263
		264	It is possible to activate the most recently seen match or a list of matches
		265	from the keyboard. Simply bind a keysym to "perl:matcher:last" or
		266	"perl:matcher:list" as seen in the example below.
		267
		268	Example configuration:
		269
		270	URxvt.perl-ext: default,matcher
		271	URxvt.urlLauncher: sensible-browser
		272	URxvt.keysym.C-Delete: perl:matcher:last
		273	URxvt.keysym.M-Delete: perl:matcher:list
		274	URxvt.matcher.button: 1
		275	URxvt.matcher.pattern.1: \\bwww\\.[\\w-]+\\.[\\w./?&@#-]*[\\w/-]
		276	URxvt.matcher.pattern.2: \\B(/\\S+?):(\\d+)(?=:|$)
		277	URxvt.matcher.launcher.2: gvim +$2 $1
		278
		279	=item xim-onthespot
		280
		281	This (experimental) perl extension implements OnTheSpot editing. It does
		282	not work perfectly, and some input methods don't seem to work well with
		283	OnTheSpot editing in general, but it seems to work at least for SCIM and
		284	kinput2.
		285
		286	You enable it by specifying this extension and a preedit style of
		287	C<OnTheSpot>, i.e.:
		288
		289	@@RXVT_NAME@@ -pt OnTheSpot -pe xim-onthespot
		290
		291	=item kuake<hotkey>
		292
		293	A very primitive quake-console-like extension. It was inspired by a
		294	description of how the programs C<kuake> and C<yakuake> work: Whenever the
		295	user presses a global accelerator key (by default C<F10>), the terminal
		296	will show or hide itself. Another press of the accelerator key will hide
		297	or show it again.
		298
		299	Initially, the window will not be shown when using this extension.
		300
		301	This is useful if you need a single terminal that is not using any desktop
		302	space most of the time but is quickly available at the press of a key.
		303
		304	The accelerator key is grabbed regardless of any modifiers, so this
		305	extension will actually grab a physical key just for this function.
		306
		307	If you want a quake-like animation, tell your window manager to do so
		308	(fvwm can do it).
		309
		310	=item overlay-osc
		311
		312	This extension implements some OSC commands to display timed popups on the
		313	screen - useful for status displays from within scripts. You have to read
		314	the sources for more info.

		321
		322	=item digital-clock
		323
		324	Displays a digital clock using the built-in overlay.
		325
		326	=item remote-clipboard
		327
		328	Somewhat of a misnomer, this extension adds two menu entries to the
		329	selection popup that allows one to run external commands to store the
		330	selection somewhere and fetch it again.
		331
		332	We use it to implement a "distributed selection mechanism", which just
		333	means that one command uploads the file to a remote server, and another
		334	reads it.
		335
		336	The commands can be set using the C<URxvt.remote-selection.store> and
		337	C<URxvt.remote-selection.fetch> resources. The first should read the
		338	selection to store from STDIN (always in UTF-8), the second should provide
		339	the selection data on STDOUT (also in UTF-8).
		340
		341	The defaults (which are likely useless to you) use rsh and cat:
		342
		343	URxvt.remote-selection.store: rsh ruth 'cat >/tmp/distributed-selection'
		344	URxvt.remote-selection.fetch: rsh ruth 'cat /tmp/distributed-selection'
		345
		346	=item selection-pastebin
		347
		348	This is a little rarely useful extension that uploads the selection as
		349	textfile to a remote site (or does other things). (The implementation is
		350	not currently secure for use in a multiuser environment as it writes to
		351	F</tmp> directly.).
		352
		353	It listens to the C<selection-pastebin:remote-pastebin> keyboard command,
		354	i.e.
		355
		356	URxvt.keysym.C-M-e: perl:selection-pastebin:remote-pastebin
		357
		358	Pressing this combination runs a command with C<%> replaced by the name of
		359	the textfile. This command can be set via a resource:
		360
		361	URxvt.selection-pastebin.cmd: rsync -apP % ruth:/var/www/www.ta-sa.org/files/txt/.
		362
		363	And the default is likely not useful to anybody but the few people around
		364	here :)
		365
		366	The name of the textfile is the hex encoded md5 sum of the selection, so
		367	the same content should lead to the same filename.
		368
		369	After a successful upload the selection will be replaced by the text given
		370	in the C<selection-pastebin-url> resource (again, the % is the placeholder
		371	for the filename):
		372
		373	URxvt.selection-pastebin.url: http://www.ta-sa.org/files/txt/%
		374
		375	I<Note to xrdb users:> xrdb uses the C preprocessor, which might interpret
		376	the double C</> characters as comment start. Use C<\057\057> instead,
		377	which works regardless of whether xrdb is used to parse the resource file
		378	or not.
		379
		380	=item macosx-clipboard and macosx-clipboard-native
		381
		382	These two modules implement an extended clipboard for Mac OS X. They are
		383	used like this:
		384
		385	URxvt.perl-ext-common: default,macosx-clipboard
		386	URxvt.keysym.M-c: perl:macosx-clipboard:copy
		387	URxvt.keysym.M-v: perl:macosx-clipboard:paste
		388
		389	The difference between them is that the native variant requires a
		390	perl from apple's devkit or so, and C<macosx-clipboard> requires the
		391	C<Mac::Pasteboard> module, works with other perls, has fewer bugs, is
		392	simpler etc. etc.

		800
		801	Works similar to C<@TERM_INIT>, but contains perl package/class names, which
		802	get registered as normal extensions after calling the hooks in C<@TERM_INIT>
		803	but before other extensions. Gets cleared just like C<@TERM_INIT>.

		811	=item urxvt::fatal $errormessage
		812
		813	Fatally aborts execution with the given error message (which should
		814	include a trailing newline). Avoid at all costs! The only time this
		815	is acceptable (and useful) is in the init hook, where it prevents the
		816	terminal from starting up.
		817
		818	=item urxvt::warn $string
		819
		820	Calls C<rxvt_warn> with the given string which should include a trailing
		821	newline. The module also overwrites the C<warn> builtin with a function
		822	that calls this function.
		823
		824	Using this function has the advantage that its output ends up in the
		825	correct place, e.g. on stderr of the connecting urxvtc client.
		826
		827	Messages have a size limit of 1023 bytes currently.

		833	objects that have perl extensions attached will be returned (because there
		834	is no urxvt::term object associated with others).
		835
		836	=item $time = urxvt::NOW

		867
		868	Rendition bitsets contain information about colour, font, font styles and

		870
		871	The following "macros" deal with changes in rendition sets. You should
		872	never just create a bitset, you should always modify an existing one,
