 757      * the flag. Note that "down" events are not fired here because the flags
 758      * checked here do not tell what exact keys are down.
 759      *
 760      * If one of the keys corresponding to a flag is down, we rely on
 761      * -[NSEvent keyCode] of an event whose -[NSEvent type] is
 762      * NSEventTypeFlagsChanged to know the exact key which is down, which has
 763      * the following two downsides:
 764      * - It does not work when the application is inactive as described above.
 765      * - It malfactions *after* the modifier state is changed while the
 766      *   application is inactive. It is because -[NSEvent keyCode] does not tell
 767      *   if the key is up or down, and requires to infer the current state from
 768      *   the previous state. It is still possible to fix such a malfanction by
 769      *   completely leaving your hands from the keyboard, which hopefully makes
 770      *   this implementation usable enough.
