 833      * the following two downsides:
 834      * - It does not work when the application is inactive as described above.
 835      * - It malfactions *after* the modifier state is changed while the
 836      *   application is inactive. It is because -[NSEvent keyCode] does not tell
 837      *   if the key is up or down, and requires to infer the current state from
 838      *   the previous state. It is still possible to fix such a malfanction by
 839      *   completely leaving your hands from the keyboard, which hopefully makes
 840      *   this implementation usable enough.
