We are currently intercepting CTRL X etc on key down for some extra processing we need to do (there may be better ways of doing this since GoJS already handles these shortcuts but we want to also handle them outside the diagram so this is the easiest way to handle them consistently). This works great on Windows and also works on the Mac but our Mac users would prefer to use Command X etc. We hook into the keydown event and the Command button being pressed triggers the event but not Command X. Other combinations such as Command K trigger the event. Is this a bug?
