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 from the keyboard.
		265	Simply bind a keysym to "perl:matcher" as seen in the example below.
		266
		267	Example configuration:
		268
		269	URxvt.perl-ext: default,matcher
		270	URxvt.urlLauncher: sensible-browser
		271	URxvt.keysym.C-Delete: perl:matcher
		272	URxvt.matcher.button: 1
		273	URxvt.matcher.pattern.1: \\bwww\\.[\\w-]+\\.[\\w./?&@#-]*[\\w/-]
		274	URxvt.matcher.pattern.2: \\B(/\\S+?):(\\d+)(?=:|$)
		275	URxvt.matcher.launcher.2: gvim +$2 $1
		276
		277	=item xim-onthespot
		278
		279	This (experimental) perl extension implements OnTheSpot editing. It does
		280	not work perfectly, and some input methods don't seem to work well with
		281	OnTheSpot editing in general, but it seems to work at least for SCIM and
		282	kinput2.
		283
		284	You enable it by specifying this extension and a preedit style of
		285	C<OnTheSpot>, i.e.:
		286
		287	@@RXVT_NAME@@ -pt OnTheSpot -pe xim-onthespot
		288
		289	=item kuake<hotkey>
		290
		291	A very primitive quake-console-like extension. It was inspired by a
		292	description of how the programs C<kuake> and C<yakuake> work: Whenever the
		293	user presses a global accelerator key (by default C<F10>), the terminal
		294	will show or hide itself. Another press of the accelerator key will hide
		295	or show it again.
		296
		297	Initially, the window will not be shown when using this extension.
		298
		299	This is useful if you need a single terminal that is not using any desktop
		300	space most of the time but is quickly available at the press of a key.
		301
		302	The accelerator key is grabbed regardless of any modifiers, so this
		303	extension will actually grab a physical key just for this function.
		304
		305	If you want a quake-like animation, tell your window manager to do so
		306	(fvwm can do it).
		307
		308	=item overlay-osc
		309
		310	This extension implements some OSC commands to display timed popups on the
		311	screen - useful for status displays from within scripts. You have to read
		312	the sources for more info.

		319
		320	=item digital-clock
		321
		322	Displays a digital clock using the built-in overlay.
		323
		324	=item remote-clipboard
		325
		326	Somewhat of a misnomer, this extension adds two menu entries to the
		327	selection popup that allows one to run external commands to store the
		328	selection somewhere and fetch it again.
		329
		330	We use it to implement a "distributed selection mechanism", which just
		331	means that one command uploads the file to a remote server, and another
		332	reads it.
		333
		334	The commands can be set using the C<URxvt.remote-selection.store> and
		335	C<URxvt.remote-selection.fetch> resources. The first should read the
		336	selection to store from STDIN (always in UTF-8), the second should provide
		337	the selection data on STDOUT (also in UTF-8).
		338
		339	The defaults (which are likely useless to you) use rsh and cat:
		340
		341	URxvt.remote-selection.store: rsh ruth 'cat >/tmp/distributed-selection'
		342	URxvt.remote-selection.fetch: rsh ruth 'cat /tmp/distributed-selection'
		343
		344	=item selection-pastebin
		345
		346	This is a little rarely useful extension that uploads the selection as
		347	textfile to a remote site (or does other things). (The implementation is
		348	not currently secure for use in a multiuser environment as it writes to
		349	F</tmp> directly.).
		350
		351	It listens to the C<selection-pastebin:remote-pastebin> keyboard command,
		352	i.e.
		353
		354	URxvt.keysym.C-M-e: perl:selection-pastebin:remote-pastebin
		355
		356	Pressing this combination runs a command with C<%> replaced by the name of
		357	the textfile. This command can be set via a resource:
		358
		359	URxvt.selection-pastebin.cmd: rsync -apP % ruth:/var/www/www.ta-sa.org/files/txt/.
		360
		361	And the default is likely not useful to anybody but the few people around
		362	here :)
		363
		364	The name of the textfile is the hex encoded md5 sum of the selection, so
		365	the same content should lead to the same filename.
		366
		367	After a successful upload the selection will be replaced by the text given
		368	in the C<selection-pastebin-url> resource (again, the % is the placeholder
		369	for the filename):
		370
		371	URxvt.selection-pastebin.url: http://www.ta-sa.org/files/txt/%
		372
		373	I<Note to xrdb users:> xrdb uses the C preprocessor, which might interpret
		374	the double C</> characters as comment start. Use C<\057\057> instead,
		375	which works regardless of whether xrdb is used to parse the resource file
		376	or not.
		377
		378	=item macosx-clipboard and macosx-clipboard-native
		379
		380	These two modules implement an extended clipboard for Mac OS X. They are
		381	used like this:
		382
		383	URxvt.perl-ext-common: default,macosx-clipboard
		384	URxvt.keysym.M-c: perl:macosx-clipboard:copy
		385	URxvt.keysym.M-v: perl:macosx-clipboard:paste
		386
		387	The difference between them is that the native variant requires a
		388	perl from apple's devkit or so, and C<macosx-clipboard> requires the
		389	C<Mac::Pasteboard> module, works with other perls, has fewer bugs, is
		390	simpler etc. etc.

		806

		811	that calls this function.
		812
		813	Using this function has the advantage that its output ends up in the
		814	correct place, e.g. on stderr of the connecting urxvtc client.

		856
		857	Rendition bitsets contain information about colour, font, font styles and

		859
		860	The following "macros" deal with changes in rendition sets. You should
		861	never just create a bitset, you should always modify an existing one,
