+=head2 SEARCH MODE (AND EXTEND MODE)
+
+Search mode is a special mode which lets you type a search string (a Perl
+regex) and then select one of the matches. Afterwards you can extend the
+match. For example select the complete word or to the end of the line. This
+allows quick selection of arbitrary text.
+
+The following mappings are available during the extension mode (not
+configurable at the moment):
+
+=over 4
+
+=item B<w> select current word
+
+=item B<b> extend word to the left
+
+=item B<e> extend word to the right
+
+=item B<W> select current WORD
+
+=item B<B> extend WORD to the left
+
+=item B<E> extend WORD to the right
+
+=item B<0> extend to beginning of line
+
+=item B<$> extend to end of line
