49	It also offers the following bindable event:	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.
		74
		75	This extension also offers following bindable keyboard commands:

71	=item digital-clock	98	Other extensions can extend this popup menu by pushing a code reference
		99	onto C<@{ $term->{selection_popup_hook} }>, that is called whenever the
		100	popup is displayed.
72		101
73	Displays a digital clock using the built-in overlay.	102	It's sole argument is the popup menu, which can be modified. The selection
		103	is in C<$_>, 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 {
		113	/a/ ? ("a to be" => sub { s/a/b/g }
		114	: ()
		115	};
		116
		117	=item searchable-scrollback<hotkey> (enabled by default)
		118
		119	Adds regex search functionality to the scrollback buffer, triggered
		120	by a hotkey (default: C<M-s>). While in search mode, normal terminal
		121	input/output is suspended and a regex is displayed at the bottom of the
		122	screen.
		123
		124	Inputting characters appends them to the regex and continues incremental
		125	search. C<BackSpace> removes a character from the regex, C<Up> and C<Down>
		126	search upwards/downwards in the scrollback buffer, C<End> jumps to the
		127	bottom. C<Escape> leaves search mode and returns to the point where search
		128	was started, while C<Enter> or C<Return> stay at the current position and
		129	additionally stores the first match in the current line into the primary
		130	selection.
		131
		132	=item readline (enabled by default)
		133
		134	A support package that tries to make editing with readline easier. At the
		135	moment, it reacts to clicking with the left mouse button by trying to
		136	move the text cursor to this position. It does so by generating as many
		137	cursor-left or cursor-right keypresses as required (the this only works
		138	for programs that correctly support wide characters).
		139
		140	To avoid too many false positives, this is only done when:
		141
		142	=over 4
		143
		144	=item - the mouse is on the same (multi-row-) line as the text cursor.
		145
		146	=item - the primary screen is currently being displayed.
		147
		148	=item - the text cursor is visible.
		149
		150	=back
		151
		152	The normal selection mechanism isn't disabled, so quick successive clicks
		153	might interfere with selection creation in harmless ways.
		154
		155	=item selection-autotransform
		156
		157	This selection allows you to do automatic transforms on a selection
		158	whenever a selection is made.
		159
		160	It works by specifying perl snippets (most useful is a single C<s///>
		161	operator) that modify C<$_> as resources:
		162
		163	URxvt.selection-autotransform.0: transform
		164	URxvt.selection-autotransform.1: transform
		165	...
		166
		167	For example, the following will transform selections of the form
		168	C<filename:number>, often seen in compiler messages, into C<vi +$filename
		169	$word>:
		170
		171	URxvt.selection-autotransform.0: s/^([^:[:space:]]+):(\\d+):?$/vi +$2 \\Q$1\\E\\x0d/
		172
		173	And this example matches the same,but replaces it with vi-commands you can
		174	paste directly into your (vi :) editor:
		175
		176	URxvt.selection-autotransform.0: s/^([^:[:space:]]+(\\d+):?$/:e \\Q$1\\E\\x0d:$2\\x0d/
		177
		178	Of course, this can be modified to suit your needs and your editor :)
		179
		180	To expand the example above to typical perl error messages ("XXX at
		181	FILENAME line YYY."), you need a slightly more elaborate solution:
		182
		183	URxvt.selection.pattern-0: ( at .*? line \\d+[,.])
		184	URxvt.selection-autotransform.0: s/^ at (.*?) line (\\d+)[,.]$/:e \\Q$1\E\\x0d:$2\\x0d/
		185
		186	The first line tells the selection code to treat the unchanging part of
		187	every error message as a selection pattern, and the second line transforms
		188	the message into vi commands to load the file.
		189
		190	=item tabbed
		191
		192	This transforms the terminal into a tabbar with additional terminals, that
		193	is, it implements what is commonly refered to as "tabbed terminal". The topmost line
		194	displays a "[NEW]" button, which, when clicked, will add a new tab, followed by one
		195	button per tab.
		196
		197	Clicking a button will activate that tab. Pressing B<Shift-Left> and
		198	B<Shift-Right> will switch to the tab left or right of the current one,
		199	while B<Shift-Down> creates a new tab.
74		200
75	=item mark-urls	201	=item mark-urls

		204	make them clickable. When middle-clicked, the program specified in the
		205	resource C<urlLauncher> (default C<x-www-browser>) will be started with
		206	the URL as first argument.
		207
		208	=item automove-background
		209
		210	This is basically a one-line extension that dynamically changes the background pixmap offset
		211	to the window position, in effect creating the same effect as pseudo transparency with
		212	a custom pixmap. No scaling is supported in this mode. Exmaple:
		213

		232	=item selection-pastebin
		233
		234	This is a little rarely useful extension that Uploads the selection as
		235	textfile to a remote site (or does other things). (The implementation is
		236	not currently secure for use in a multiuser environment as it writes to
		237	F</tmp> directly.).
		238
		239	It listens to the C<selection-pastebin:remote-pastebin> keyboard command,
		240	i.e.
		241
		242	URxvt.keysym.C-M-e: perl:selection-pastebin:remote-pastebin
		243
		244	Pressing this combination runs a command with C<%> replaced by the name of
		245	the textfile. This command can be set via a resource:
		246
		247	URxvt.selection-pastebin.cmd: rsync -apP % ruth:/var/www/www.ta-sa.org/files/txt/.
		248
		249	And the default is likely not useful to anybody but the few people around
		250	here :)
		251
		252	The name of the textfile is the hex encoded md5 sum of the selection, so
		253	the same content should lead to the same filename.
		254
		255	After a successful upload the selection will be replaced by the text given
		256	in the C<selection-pastebin-url> resource (again, the % is the placeholder
		257	for the filename):
		258
		259	URxvt.selection-pastebin.url: http://www.ta-sa.org/files/txt/%

		301	=head2 Extension Objects
		302
		303	Very perl extension is a perl class. A separate perl object is created
		304	for each terminal and each extension and passed as the first parameter to
		305	hooks. So extensions can use their C<$self> object without having to think
		306	about other extensions, with the exception of methods and members that
		307	begin with an underscore character C<_>: these are reserved for internal
		308	use.
		309
		310	Although it isn't a C<urxvt::term> object, you can call all methods of the
		311	C<urxvt::term> class on this object.
		312
		313	It has the following methods and data members:
