Fix remaining issues with menu keyboard navigation (#3248)

* Fix remaining issues with menu keyboard navigation
* Entry menu now locks focus on entry when used from menubar
* When using keyboard navigation to select menubar menus,
  do not lose focus on selected entry (fixes #3246)
* Enable all entry keyboard shortcuts while in search (fixes #3034)
* When the search text edit has focus, retain selected entry keyboard
  shortcuts and button pressing capability
