NSText handles this properly; when it posts an NSTextDidEndEditingNotification,
that includes NSTextMovement as a key. I'm not sure if
NSControlTextDidEndEditingNotification is kind enough to pass that on too, or
if you'll have to listen out for the original notification from the field
editor._______________________________________________
