 780      * the flag. Note that "down" events are not fired here because the flags
 781      * checked here do not tell what exact keys are down.
 782      *
 783      * If one of the keys corresponding to a flag is down, we rely on
 784      * -[NSEvent keyCode] of an event whose -[NSEvent type] is
 785      * NSEventTypeFlagsChanged to know the exact key which is down, which has
 786      * the following two downsides:
 787      * - It does not work when the application is inactive as described above.
 788      * - It malfactions *after* the modifier state is changed while the
 789      *   application is inactive. It is because -[NSEvent keyCode] does not tell
 790      *   if the key is up or down, and requires to infer the current state from
 791      *   the previous state. It is still possible to fix such a malfanction by
 792      *   completely leaving your hands from the keyboard, which hopefully makes
 793      *   this implementation usable enough.
