title: Check if a menu item event if coming from a click or shortcut
body: <p>Is there anyway to check if a menu item event is coming from a click in the menu or from a short cut key being pressed?</p>
  
  <p>I've tried adding event handlers to the key press and key down events, however these events aren't being "fired" when it's a shortcut key that's pressed (They do work as expected when it's not a shortcut key). I couldn't find anything in the sender object that was different between the menu click or shortcut click.</p>
