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	You can look at the source of the selection extension to see more
		73	interesting uses, such as parsing a line from beginning to end.

		97
		98	Other extensions can extend this popup menu by pushing a code reference
		99	onto C<@{ $term->{selection_popup_hook} }>, that is called whenever the
		100	popup is displayed.
		101
		102	It's sole argument is the popup menu, which can be modified. The selection
		103	is in C<$_>, which can be used to decide wether to add something or not.
		104	It should either return nothing or a string and a code reference. The
		105	string will be used as button text and the code reference will be called
		106	when the button gets activated and should transform C<$_>.
		107
		108	The following will add an entry C<a to b> that transforms all C<a>s in
		109	the selection to C<b>s, but only if the selection currently contains any
		110	C<a>s:
		111
		112	push @{ $self->{term}{selection_popup_hook} }, sub {

		130	selection.
82		131
83	=item digital-clock	132	=item selection-autotransform
84		133
85	Displays a digital clock using the built-in overlay.	134	This selection allows you to do automatic transforms on a selection
		135	whenever a selection is made.
		136
		137	It works by specifying perl snippets (most useful is a single C<s///>
		138	operator) that modify C<$_> as resources:
		139
		140	URxvt.selection-autotransform.0: transform
		141	URxvt.selection-autotransform.1: transform
		142	...
		143
		144	For example, the following will transform selections of the form
		145	C<filename:number>, often seen in compiler messages, into C<vi +$filename
		146	$word>:
		147
		148	URxvt.selection-autotransform.0: s/^([^:[:space:]]+):(\\d+):?$/vi +$2 \\Q$1\\E\\x0d/
		149
		150	And this example matches the same,but replaces it with vi-commands you can
		151	paste directly into your (vi :) editor:
		152
		153	URxvt.selection-autotransform.0: s/^([^:[:space:]]+(\\d+):?$/:e \\Q$1\\E\\x0d:$2\\x0d/
		154
		155	Of course, this can be modified to suit your needs and your editor :)
		156
		157	To expand the example above to typical perl error messages ("XXX at
		158	FILENAME line YYY."), you need a slightly more elaborate solution:
		159
		160	URxvt.selection.pattern-0: ( at .*? line \\d+[,.])
		161	URxvt.selection-autotransform.0: s/^ at (.*?) line (\\d+)[,.]$/:e \\Q$1\E\\x0d:$2\\x0d/
		162
		163	The first line tells the selection code to treat the unchanging part of
		164	every error message as a selection pattern, and the second line transforms
		165	the message into vi commands to load the file.
		166
		167	=item readline
		168
		169	A support package that tries to make editing with readline easier. At the
		170	moment, it reacts to clicking with the left mouse button by trying to
		171	move the text cursor to this position. It does so by generating as many
		172	cursor-left or cursor-right keypresses as required (the this only works
		173	for programs that correctly support wide characters).
		174
		175	It only works when clicking into the same line (possibly extended over
		176	multiple rows) as the text cursor and on the primary screen, to reduce the
		177	risk of misinterpreting. The normal selection isn't disabled, so quick
		178	successive clicks might interfere with selection creation in harmless
		179	ways.
		180
		181	=item tabbed
		182
		183	This transforms the terminal into a tabbar with additional terminals, that
		184	is, it implements what is commonly refered to as "tabbed terminal". The topmost line
		185	displays a "[NEW]" button, which, when clicked, will add a new tab, followed by one
		186	button per tab.
		187
		188	Clicking a button will activate that tab. Pressing B<Shift-Left> and
		189	B<Shift-Right> will switch to the tab left or right of the current one,
		190	while B<Shift-Down> creates a new tab.
86		191

		197	the URL as first argument.
		198
		199	=item automove-background
		200
		201	This is basically a one-line extension that dynamically changes the background pixmap offset
		202	to the window position, in effect creating the same effect as pseudo transparency with
		203	a custom pixmap. No scaling is supported in this mode. Exmaple:

		222
		223	=item selection-pastebin
		224
		225	This is a little rarely useful extension that Uploads the selection as
		226	textfile to a remote site (or does other things). (The implementation is
		227	not currently secure for use in a multiuser environment as it writes to
		228	F</tmp> directly.).
		229
		230	It listens to the C<selection-pastebin:remote-pastebin> keyboard command,
		231	i.e.
		232
		233	URxvt.keysym.C-M-e: perl:selection-pastebin:remote-pastebin
		234
		235	Pressing this combination runs a command with C<%> replaced by the name of
		236	the textfile. This command can be set via a resource:
		237
		238	URxvt.selection-pastebin.cmd: rsync -apP % ruth:/var/www/www.ta-sa.org/files/txt/.
		239
		240	And the default is likely not useful to anybody but the few people around
		241	here :)
		242
		243	The name of the textfile is the hex encoded md5 sum of the selection, so
		244	the same content should lead to the same filename.
		245
		246	After a successful upload the selection will be replaced by the text given
		247	in the C<selection-pastebin-url> resource (again, the % is the placeholder
		248	for the filename):
		249
		250	URxvt.selection-pastebin.url: http://www.ta-sa.org/files/txt/%
