 <p>Of course, this can be modified to suit your needs and your editor :)</p>

+<p>To expand the example above to typical perl error messages (``XXX at
+FILENAME line YYY.''), you need a slightly more elaborate solution:</p>
+</dd>
+<dd>
+<pre>
+   URxvt.selection.pattern-0: ( at .*? line \\d+\\.)
+   URxvt.selection-autotransform.0: s/^ at (.*?) line (\\d+)\\.$/\x1b:e \\Q$1\E\\x0d:$2\\x0d/</pre>
+</dd>
+<dd>
+<p>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.</p>
