 (More) intelligent selection. This extension tries to be more intelligent

+arguments, which is very convenient, too, if your F<ls> supports
+C<--quoting-style=shell>.
+A double-click usually selects the word under the cursor, further clicks
+will enlarge the selection.
+The selection works by trying to match a number of regexes and displaying
+them in increasing order of length. You can add your own regexes by
+specifying resources of the form:
+   URxvt.selection.pattern-0: perl-regex
+   URxvt.selection.pattern-1: perl-regex
+   ...
+The index number (0, 1...) must not have any holes, and each regex must
+contain at least one pair of capturing parentheses, which will be used for
+the match. For example, the followign adds a regex that matches everything
+between two vertical bars:
+   URxvt.selection.pattern-0: \\|([^|]+)\\|
+You can look at the source of the selection extension to see more
+interesting uses, such as parsing a line from beginning to end.

-=item digital-clock
+=item selection-autotransform
-Displays a digital clock using the built-in overlay.
+This selection allows you to do automatic transforms on a selection
+whenever a selection is made.
+It works by specifying perl snippets (most useful is a single C<s///>
+operator) that modify C<$_> as resources:
+   URxvt.selection-autotransform.0: transform
+   URxvt.selection-autotransform.1: transform
+   ...
+For example, the following will transform selections of the form
+C<filename:number>, often seen in compiler messages, into C<vi +$filename
+$word>:
+   URxvt.selection-autotransform.0: s/^(\\S+):(\\d+):?$/vi +$2 \\Q$1\\E\\x0d/
+And this example matches the same,but replaces it with vi-commands you can
+paste directly into your (vi :) editor:
+   URxvt.selection-autotransform.0: s/^(S+):(d+):?$/\\x1b:e \\Q$1\\E\\x0d:$2\\x0d/
+Of course, this can be modified to suit your needs and your editor :)
+To expand the example above to typical perl error messages ("XXX at
+FILENAME line YYY."), you need a slightly more elaborate solution:
+   URxvt.selection.pattern-0: ( at .*? line \\d+\\.)
+   URxvt.selection-autotransform.0: s/^ at (.*?) line (\\d+)\\.$/\x1b:e \\Q$1\E\\x0d:$2\\x0d/
+The first line tells the selection code to treat the unchanging part of
+every error message as a selection pattern, and the second line transforms
+the message into vi commands to load the file.
 =item mark-urls
 Uses per-line display filtering (C<on_line_update>) to underline urls and
 make them clickable. When middle-clicked, the program specified in the
-resource C<urlLauncher> (default C<x-www-browser>) will be started.
+resource C<urlLauncher> (default C<x-www-browser>) will be started with
+the URL as first argument.
 =item block-graphics-to-ascii
 A not very useful example of filtering all text output to the terminal,
 by replacing all line-drawing characters (U+2500 .. U+259F) by a
 similar-looking ascii character.
+=item digital-clock
+Displays a digital clock using the built-in overlay.
 =item example-refresh-hooks
 Displays a very simple digital clock in the upper right corner of the
 window. Illustrates overwriting the refresh callbacks to create your own
 =item on_sel_extend $term
 Called whenever the user tries to extend the selection (e.g. with a double
 click) and is either supposed to return false (normal operation), or
 should extend the selection itelf and return true to suppress the built-in
-processing.
+processing. This can happen multiple times, as long as the callback
+returns true, it will be called on every further click by the user and is
+supposed to enlarge the selection more and more, if possible.
 See the F<selection> example extension.
 =item on_view_change $term, $offset
 Called whenever the user presses a key combination that has a
 C<perl:string> action bound to it (see description of the B<keysym>
 resource in the @@RXVT_NAME@@(1) manpage).
+=item on_x_event $term, $event
+Called on every X event received on the vt window (and possibly other
+windows). Should only be used as a last resort. Most event structure

 Called whenever the window gets the keyboard focus, before rxvt-unicode
 does focus in processing.
