Typeahead find for Disobedience searching. This is implemented by

hackily redirecting most keyboard events sent to the main view to the
search entry.

^F focuses it, which is probably wrong given you can type into it
anyway.  ^G moves to the next match, which is why ^F focusing is
wrong, because ^G breaks when you're focused on the search entry.

The next/prev buttons (and ^G) now loop when you reach the end.
