 834      * If one of the keys corresponding to a flag is down, we rely on
 835      * -[NSEvent keyCode] of an event whose -[NSEvent type] is
 836      * NSEventTypeFlagsChanged to know the exact key which is down, which has
 837      * the following two downsides:
 838      * - It does not work when the application is inactive as described above.
 839      * - It malfactions *after* the modifier state is changed while the
 840      *   application is inactive. It is because -[NSEvent keyCode] does not tell
 841      *   if the key is up or down, and requires to infer the current state from
 842      *   the previous state. It is still possible to fix such a malfanction by
 843      *   completely leaving your hands from the keyboard, which hopefully makes
 844      *   this implementation usable enough.
