44	(More) intelligent selection. This extension tries to be more intelligent	48	Extensions that add command line parameters or resources on their own are
45	when the user extends selections (double-click and further clicks). Right	49	loaded automatically when used.
46	now, it tries to select words, urls and complete shell-quoted
47	arguments, which is very convenient, too, if your F<ls> supports
48	C<--quoting-style=shell>.
49
50	A double-click usually selects the word under the cursor, further clicks
51	will enlarge the selection.
52
53	The selection works by trying to match a number of regexes and displaying
54	them in increasing order of length. You can add your own regexes by
55	specifying resources of the form:
56
57	URxvt.selection.pattern-0: perl-regex
58	URxvt.selection.pattern-1: perl-regex
59	...
60
61	The index number (0, 1...) must not have any holes, and each regex must
62	contain at least one pair of capturing parentheses, which will be used for
63	the match. For example, the followign adds a regex that matches everything
64	between two vertical bars:
65
66	URxvt.selection.pattern-0: \\|([^|]+)\\|
67
68	You can look at the source of the selection extension to see more
69	interesting uses, such as parsing a line from beginning to end.
70
71	This extension also offers the following bindable keyboard command:
72
73	=over 4
74
75	=item rot13
76
77	Rot-13 the selection when activated. Used via keyboard trigger:
78
79	URxvt.keysym.C-M-r: perl:selection:rot13
80
81	=back
82
83	=item option-popup (enabled by default)
84
85	Binds a popup menu to Ctrl-Button2 that lets you toggle (some) options at
86	runtime.
87
88	=item selection-popup (enabled by default)
89
90	Binds a popup menu to Ctrl-Button3 that lets you convert the selection
91	text into various other formats/action (such as uri unescaping, perl
92	evalution, web-browser starting etc.), depending on content.
93
94	=item searchable-scrollback<hotkey> (enabled by default)
95
96	Adds regex search functionality to the scrollback buffer, triggered
97	by a hotkey (default: C<M-s>). While in search mode, normal terminal
98	input/output is suspended and a regex is displayed at the bottom of the
99	screen.
100
101	Inputting characters appends them to the regex and continues incremental
102	search. C<BackSpace> removes a character from the regex, C<Up> and C<Down>
103	search upwards/downwards in the scrollback buffer, C<End> jumps to the
104	bottom. C<Escape> leaves search mode and returns to the point where search
105	was started, while C<Enter> or C<Return> stay at the current position and
106	additionally stores the first match in the current line into the primary
107	selection.
108
109	=item selection-autotransform
110
111	This selection allows you to do automatic transforms on a selection
112	whenever a selection is made.
113
114	It works by specifying perl snippets (most useful is a single C<s///>
115	operator) that modify C<$_> as resources:
116
117	URxvt.selection-autotransform.0: transform
118	URxvt.selection-autotransform.1: transform
119	...
120
121	For example, the following will transform selections of the form
122	C<filename:number>, often seen in compiler messages, into C<vi +$filename
123	$word>:
124
125	URxvt.selection-autotransform.0: s/^([^:[:space:]]+):(\\d+):?$/vi +$2 \\Q$1\\E\\x0d/
126
127	And this example matches the same,but replaces it with vi-commands you can
128	paste directly into your (vi :) editor:
129
130	URxvt.selection-autotransform.0: s/^([^:[:space:]]+(\\d+):?$/\\x1b:e \\Q$1\\E\\x0d:$2\\x0d/
131
132	Of course, this can be modified to suit your needs and your editor :)
133
134	To expand the example above to typical perl error messages ("XXX at
135	FILENAME line YYY."), you need a slightly more elaborate solution:
136
137	URxvt.selection.pattern-0: ( at .*? line \\d+\\.)
138	URxvt.selection-autotransform.0: s/^ at (.*?) line (\\d+)\\.$/\x1b:e \\Q$1\E\\x0d:$2\\x0d/
139
140	The first line tells the selection code to treat the unchanging part of
141	every error message as a selection pattern, and the second line transforms
142	the message into vi commands to load the file.
143
144	=item mark-urls
145
146	Uses per-line display filtering (C<on_line_update>) to underline urls and
147	make them clickable. When middle-clicked, the program specified in the
148	resource C<urlLauncher> (default C<x-www-browser>) will be started with
149	the URL as first argument.
150
151	=item block-graphics-to-ascii
152
153	A not very useful example of filtering all text output to the terminal,
154	by replacing all line-drawing characters (U+2500 .. U+259F) by a
155	similar-looking ascii character.
156
157	=item digital-clock
158
159	Displays a digital clock using the built-in overlay.
160
161	=item example-refresh-hooks
