If I type a word that is in the dictionary already and press Enter or Tab, The Combine shows a dialog to let me choose an existing entry or create a new one. I can use the up and down arrows and press enter to select an entry (good). However, after I select an entry, I need to press Tab twice before I can use the arrow keys and Enter to select a sense (expected: I can immediately press Enter without having to press Tab twice).
