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 tty is in ICANON state.
		145
		146	=item - the text cursor is visible.
		147
		148	=item - the primary screen is currently being displayed.
		149
		150	=item - the mouse is on the same (multi-row-) line as the text cursor.
		151
		152	=back
		153
		154	The normal selection mechanism isn't disabled, so quick successive clicks
		155	might interfere with selection creation in harmless ways.
		156
		157	=item selection-autotransform
		158
		159	This selection allows you to do automatic transforms on a selection
		160	whenever a selection is made.
		161
		162	It works by specifying perl snippets (most useful is a single C<s///>
		163	operator) that modify C<$_> as resources:
		164
		165	URxvt.selection-autotransform.0: transform
		166	URxvt.selection-autotransform.1: transform
		167	...
		168
		169	For example, the following will transform selections of the form
		170	C<filename:number>, often seen in compiler messages, into C<vi +$filename
		171	$word>:
		172
		173	URxvt.selection-autotransform.0: s/^([^:[:space:]]+):(\\d+):?$/vi +$2 \\Q$1\\E\\x0d/
		174
		175	And this example matches the same,but replaces it with vi-commands you can
		176	paste directly into your (vi :) editor:
		177
		178	URxvt.selection-autotransform.0: s/^([^:[:space:]]+(\\d+):?$/:e \\Q$1\\E\\x0d:$2\\x0d/
		179
		180	Of course, this can be modified to suit your needs and your editor :)
		181
		182	To expand the example above to typical perl error messages ("XXX at
		183	FILENAME line YYY."), you need a slightly more elaborate solution:
		184
		185	URxvt.selection.pattern-0: ( at .*? line \\d+[,.])
		186	URxvt.selection-autotransform.0: s/^ at (.*?) line (\\d+)[,.]$/:e \\Q$1\E\\x0d:$2\\x0d/
		187
		188	The first line tells the selection code to treat the unchanging part of
		189	every error message as a selection pattern, and the second line transforms
		190	the message into vi commands to load the file.
		191
		192	=item tabbed
		193
		194	This transforms the terminal into a tabbar with additional terminals, that
		195	is, it implements what is commonly refered to as "tabbed terminal". The topmost line
		196	displays a "[NEW]" button, which, when clicked, will add a new tab, followed by one
		197	button per tab.
		198
		199	Clicking a button will activate that tab. Pressing B<Shift-Left> and
		200	B<Shift-Right> will switch to the tab left or right of the current one,
		201	while B<Shift-Down> creates a new tab.
74		202
75	=item mark-urls	203	=item mark-urls

		206	make them clickable. When middle-clicked, the program specified in the
		207	resource C<urlLauncher> (default C<x-www-browser>) will be started with
		208	the URL as first argument.
		209
		210	=item automove-background
		211
		212	This is basically a one-line extension that dynamically changes the background pixmap offset
		213	to the window position, in effect creating the same effect as pseudo transparency with
		214	a custom pixmap. No scaling is supported in this mode. Exmaple:
		215

		234	=item selection-pastebin
		235
		236	This is a little rarely useful extension that Uploads the selection as
		237	textfile to a remote site (or does other things). (The implementation is
		238	not currently secure for use in a multiuser environment as it writes to
		239	F</tmp> directly.).
		240
		241	It listens to the C<selection-pastebin:remote-pastebin> keyboard command,
		242	i.e.
		243
		244	URxvt.keysym.C-M-e: perl:selection-pastebin:remote-pastebin
		245
		246	Pressing this combination runs a command with C<%> replaced by the name of
		247	the textfile. This command can be set via a resource:
		248
		249	URxvt.selection-pastebin.cmd: rsync -apP % ruth:/var/www/www.ta-sa.org/files/txt/.
		250
		251	And the default is likely not useful to anybody but the few people around
		252	here :)
		253
		254	The name of the textfile is the hex encoded md5 sum of the selection, so
		255	the same content should lead to the same filename.
		256
		257	After a successful upload the selection will be replaced by the text given
		258	in the C<selection-pastebin-url> resource (again, the % is the placeholder
		259	for the filename):
		260
		261	URxvt.selection-pastebin.url: http://www.ta-sa.org/files/txt/%

		303	=head2 Extension Objects
		304
		305	Very perl extension is a perl class. A separate perl object is created
		306	for each terminal and each extension and passed as the first parameter to
		307	hooks. So extensions can use their C<$self> object without having to think
		308	about other extensions, with the exception of methods and members that
		309	begin with an underscore character C<_>: these are reserved for internal
		310	use.
		311
		312	Although it isn't a C<urxvt::term> object, you can call all methods of the
		313	C<urxvt::term> class on this object.
		314
		315	It has the following methods and data members:
		316
		317	=over 4
