Currently the undo/redo functionality is implemented so that the text pane needs focus and captures key strokes.
I see two possibilities to improve the user experience:
add buttons for undo/redo above the text pane / after the Open/Save/Validate buttons.
Protégé has a separate functionality for undo/redo, that is available in the Edit menu. It might be possible to integrate with this, however I fear this could get complicated.
