48		53
		54	A double-click usually selects the word under the cursor, further clicks
		55	will enlarge the selection.
		56
		57	The selection works by trying to match a number of regexes and displaying
		58	them in increasing order of length. You can add your own regexes by
		59	specifying resources of the form:
		60
		61	URxvt.selection.pattern-0: perl-regex
		62	URxvt.selection.pattern-1: perl-regex
		63	...
		64
		65	The index number (0, 1...) must not have any holes, and each regex must
		66	contain at least one pair of capturing parentheses, which will be used for
		67	the match. For example, the followign adds a regex that matches everything
		68	between two vertical bars:
		69
		70	URxvt.selection.pattern-0: \\\|([^\|]+)\\\|
		71
		72	Another example: Programs I use often output "absolute path: " at the
		73	beginning of a line when they process multiple files. The following
		74	pattern matches the filename (note, there is a single space at the very
		75	end):
		76
		77	URxvt.selection.pattern-0: ^(/[^:]+):\
		78
		79	You can look at the source of the selection extension to see more
		80	interesting uses, such as parsing a line from beginning to end.

		132	The following will add an entry C<a to b> that transforms all C<a>s in

		154	selection.
82		155
83	=item digital-clock	156	The regex defaults to "(?i)", resulting in a case-insensitive search. To
		157	get a case-sensitive search you can delete this prefix using C<BackSpace>
		158	or simply use an uppercase character which removes the "(?i)" prefix.
84		159
85	Displays a digital clock using the built-in overlay.	160	See L<perlre> for more info about perl regular expression syntax.
		161
		162	=item readline (enabled by default)
		163
		164	A support package that tries to make editing with readline easier. At
		165	the moment, it reacts to clicking shift-left mouse button by trying to
		166	move the text cursor to this position. It does so by generating as many
		167	cursor-left or cursor-right keypresses as required (the this only works
		168	for programs that correctly support wide characters).
		169
		170	To avoid too many false positives, this is only done when:
		171
		172	=over 4
		173
		174	=item - the tty is in ICANON state.
		175
		176	=item - the text cursor is visible.
		177
		178	=item - the primary screen is currently being displayed.
		179
		180	=item - the mouse is on the same (multi-row-) line as the text cursor.
		181
		182	=back
		183
		184	The normal selection mechanism isn't disabled, so quick successive clicks
		185	might interfere with selection creation in harmless ways.
		186
		187	=item selection-autotransform
		188
		189	This selection allows you to do automatic transforms on a selection
		190	whenever a selection is made.
		191
		192	It works by specifying perl snippets (most useful is a single C<s///>
		193	operator) that modify C<$_> as resources:
		194
		195	URxvt.selection-autotransform.0: transform
		196	URxvt.selection-autotransform.1: transform
		197	...
		198
		199	For example, the following will transform selections of the form
		200	C<filename:number>, often seen in compiler messages, into C<vi +$filename
		201	$word>:
		202
		203	URxvt.selection-autotransform.0: s/^([^:[:space:]]+):(\\d+):?$/vi +$2 \\Q$1\\E\\x0d/
		204
		205	And this example matches the same,but replaces it with vi-commands you can
		206	paste directly into your (vi :) editor:
		207
		208	URxvt.selection-autotransform.0: s/^([^:[:space:]]+(\\d+):?$/:e \\Q$1\\E\\x0d:$2\\x0d/
		209
		210	Of course, this can be modified to suit your needs and your editor :)
		211
		212	To expand the example above to typical perl error messages ("XXX at
		213	FILENAME line YYY."), you need a slightly more elaborate solution:
		214
		215	URxvt.selection.pattern-0: ( at .*? line \\d+[,.])
		216	URxvt.selection-autotransform.0: s/^ at (.*?) line (\\d+)[,.]$/:e \\Q$1\E\\x0d:$2\\x0d/
		217
		218	The first line tells the selection code to treat the unchanging part of
		219	every error message as a selection pattern, and the second line transforms
		220	the message into vi commands to load the file.
		221
		222	=item tabbed
		223
		224	This transforms the terminal into a tabbar with additional terminals, that
		225	is, it implements what is commonly refered to as "tabbed terminal". The topmost line
		226	displays a "[NEW]" button, which, when clicked, will add a new tab, followed by one
		227	button per tab.
		228
		229	Clicking a button will activate that tab. Pressing B<Shift-Left> and
		230	B<Shift-Right> will switch to the tab left or right of the current one,
		231	while B<Shift-Down> creates a new tab.
		232
		233	The tabbar itself can be configured similarly to a normal terminal, but
		234	with a resource class of C<URxvt.tabbed>. In addition, it supports the
		235	following four resources (shown with defaults):
		236
		237	URxvt.tabbed.tabbar-fg: <colour-index, default 3>
		238	URxvt.tabbed.tabbar-bg: <colour-index, default 0>
		239	URxvt.tabbed.tab-fg: <colour-index, default 0>
		240	URxvt.tabbed.tab-bg: <colour-index, default 1>
		241
		242	See I<COLOR AND GRAPHICS> in the @@RXVT_NAME@@(1) manpage for valid
		243	indices.

		250	the URL as first argument.
		251
		252	=item xim-onthespot
		253
		254	This (experimental) perl extension implements OnTheSpot editing. It does
		255	not work perfectly, and some input methods don't seem to work well with
		256	OnTheSpot editing in general, but it seems to work at leats for SCIM and
		257	kinput2.
		258
		259	You enable it by specifying this extension and a preedit style of
		260	C<OnTheSpot>, i.e.:
		261
		262	@@RXVT_NAME@@ -pt OnTheSpot -pe xim-onthespot
		263
		264	=item automove-background
		265
		266	This is basically a very small extension that dynamically changes the
		267	background pixmap offset to the window position, in effect creating the
		268	same effect as pseudo transparency with a custom pixmap. No scaling is
		269	supported in this mode. Exmaple:
		270

		278
		279	=item digital-clock
		280
		281	Displays a digital clock using the built-in overlay.
		282
		283	=item remote-clipboard
		284
		285	Somewhat of a misnomer, this extension adds two menu entries to the
		286	selection popup that allows one ti run external commands to store the
		287	selection somewhere and fetch it again.
		288
		289	We use it to implement a "distributed selection mechanism", which just
		290	means that one command uploads the file to a remote server, and another
		291	reads it.
		292
		293	The commands can be set using the C<URxvt.remote-selection.store> and
		294	C<URxvt.remote-selection.fetch> resources. The first should read the
		295	selection to store from STDIN (always in UTF-8), the second should provide
		296	the selection data on STDOUT (also in UTF-8).
		297
		298	The defaults (which are likely useless to you) use rsh and cat:
		299
		300	URxvt.remote-selection.store: rsh ruth 'cat >/tmp/distributed-selection'
		301	URxvt.remote-selection.fetch: rsh ruth 'cat /tmp/distributed-selection'
		302
		303	=item selection-pastebin
		304
		305	This is a little rarely useful extension that Uploads the selection as
		306	textfile to a remote site (or does other things). (The implementation is
		307	not currently secure for use in a multiuser environment as it writes to
		308	F</tmp> directly.).
		309
		310	It listens to the C<selection-pastebin:remote-pastebin> keyboard command,
		311	i.e.
		312
		313	URxvt.keysym.C-M-e: perl:selection-pastebin:remote-pastebin
		314
		315	Pressing this combination runs a command with C<%> replaced by the name of
		316	the textfile. This command can be set via a resource:
		317
		318	URxvt.selection-pastebin.cmd: rsync -apP % ruth:/var/www/www.ta-sa.org/files/txt/.
		319
		320	And the default is likely not useful to anybody but the few people around
		321	here :)
		322
		323	The name of the textfile is the hex encoded md5 sum of the selection, so
		324	the same content should lead to the same filename.
		325
		326	After a successful upload the selection will be replaced by the text given
		327	in the C<selection-pastebin-url> resource (again, the % is the placeholder
		328	for the filename):
		329
		330	URxvt.selection-pastebin.url: http://www.ta-sa.org/files/txt/%
