Qt menu search

Remove a 'TODO' for once.  Have the popup that's used to accept the
target string--after clicking on [search] or typing ':' to initiate
menu search+select operation--force keyboard focus to itself.  Menu
searching worked without this, but only if you manually clicked on
the search popup prior to typing the target string.  Failure to do
so resulted in typed characters being used to select menu entries.
