 =head1 USAGE
 
+Short overview of the general usage, details below:
+
+    - start fcscs
+    - configure actions (optional)
+        - enable pasting
+        - ...
+    - select mode (optional, URL mode is used on startup):
+        - f: file paths
+        - u: URLs
+        - ...
+        - /: search mode
+    - for `normal' modes:
+        - select match by displayed number or <return> for lowest numbered
+          match
+        - configured action is run, e.g. URL is opened with browser
+    - for `search' mode:
+        - perform incremental search
+        - on <return> go to `normal' mode to select a match
+        - after the match is selected wait for confirmation or extension
+        - confirmation: <return> run previously selected action
+        - extension: change match, e.g. select complete word or line

+=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<^> extend to beginning of line
+
+=item B<$> extend to end of line
+
+=back
+
+C<word> includes any characters matching C<\w+>, C<WORD> any non-whitespace
+characters (C<\S+>), just like in Vim.
