50A double-click usually selects the word under the cursor, further clicks
51will enlarge the selection.
52
53The selection works by trying to match a number of regexes and displaying
54them in increasing order of length. You can add your own regexes by
55specifying resources of the form:
56
57 URxvt.selection.pattern-0: perl-regex
58 URxvt.selection.pattern-1: perl-regex
59 ...
60
61The index number (0, 1...) must not have any holes, and each regex must
62contain at least one pair of capturing parentheses, which will be used for
63the match. For example, the followign adds a regex that matches everything
64between two vertical bars:
65
66 URxvt.selection.pattern-0: \\|([^|]+)\\|
67
68You can look at the source of the selection extension to see more
69interesting uses, such as parsing a line from beginning to end.

83=item digital-clock 109=item selection-autotransform
84 110
85Displays a digital clock using the built-in overlay. 111This selection allows you to do automatic transforms on a selection
112whenever a selection is made.
113
114It works by specifying perl snippets (most useful is a single C<s///>
115operator) that modify C<$_> as resources:
116
117 URxvt.selection-autotransform.0: transform
118 URxvt.selection-autotransform.1: transform
119 ...
120
121For example, the following will transform selections of the form
122C<word:number> into C<vi +$number $word>:
123
124 URxvt.selection-autotransform.0: s/^(S+):(d+):?$/vi +$2 $1\\x0d/
125
126And this example matches the same,but replaces it with vi-commands you can
127paste directory into your (vi :) editor:
128
129 URxvt.selection-autotransform.0: s/^(S+):(d+):?$/\\x1b:e $1\\x0d:$2\\x0d/
