- Hitting a ctrl key combo will actually call onPrepareOptionsMenu(), which
will change the state of the workspace incorrectly. Instead, listen for
the menu button, and only allow the user to enter overview mode if they
are currently not dragging or in an overlay state (like all apps or
widgets).
- Also making the overview buttons focusable so that they are focused when
you go into overview mode.
