		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

		80	interesting uses, such as parsing a line from beginning to end.

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

101		245
		246	=item xim-onthespot
		247
		248	This (experimental) perl extension implements OnTheSpot editing. It does
		249	not work perfectly, and some input methods don't seem to work well with
		250	OnTheSpot editing in general, but it seems to work at leats for SCIM and
		251	kinput2.
		252
		253	You enable it by specifying this extension and a preedit style of
		254	C<OnTheSpot>, i.e.:
		255
		256	@@RXVT_NAME@@ -pt OnTheSpot -pe xim-onthespot
		257
		258	=item automove-background
		259
		260	This is basically a one-line extension that dynamically changes the background pixmap offset
		261	to the window position, in effect creating the same effect as pseudo transparency with
		262	a custom pixmap. No scaling is supported in this mode. Exmaple:
		263

		271
		272	=item digital-clock
		273
		274	Displays a digital clock using the built-in overlay.
		275
		276	=item remote-clipboard
		277
		278	Somewhat of a misnomer, this extension adds two menu entries to the
		279	selection popup that allows one ti run external commands to store the
		280	selection somewhere and fetch it again.
		281
		282	We use it to implement a "distributed selection mechanism", which just
		283	means that one command uploads the file to a remote server, and another
		284	reads it.
		285
		286	The commands can be set using the C<URxvt.remote-selection.store> and
		287	C<URxvt.remote-selection.fetch> resources. The first should read the
		288	selection to store from STDIN (always in UTF-8), the second should provide
		289	the selection data on STDOUT (also in UTF-8).
		290
		291	The defaults (which are likely useless to you) use rsh and cat:
		292
		293	URxvt.remote-selection.store: rsh ruth 'cat >/tmp/distributed-selection'
		294	URxvt.remote-selection.fetch: rsh ruth 'cat /tmp/distributed-selection'
		295
		296	=item selection-pastebin
		297
		298	This is a little rarely useful extension that Uploads the selection as
		299	textfile to a remote site (or does other things). (The implementation is
		300	not currently secure for use in a multiuser environment as it writes to
		301	F</tmp> directly.).
		302
		303	It listens to the C<selection-pastebin:remote-pastebin> keyboard command,
		304	i.e.
		305
		306	URxvt.keysym.C-M-e: perl:selection-pastebin:remote-pastebin
		307
		308	Pressing this combination runs a command with C<%> replaced by the name of
		309	the textfile. This command can be set via a resource:
		310
		311	URxvt.selection-pastebin.cmd: rsync -apP % ruth:/var/www/www.ta-sa.org/files/txt/.
		312
		313	And the default is likely not useful to anybody but the few people around
		314	here :)
		315
		316	The name of the textfile is the hex encoded md5 sum of the selection, so
		317	the same content should lead to the same filename.
		318
		319	After a successful upload the selection will be replaced by the text given
		320	in the C<selection-pastebin-url> resource (again, the % is the placeholder
		321	for the filename):
		322
		323	URxvt.selection-pastebin.url: http://www.ta-sa.org/files/txt/%
