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