792     * If a flag is not set, fire "up" events for all keys which correspond to
793     * the flag. Note that "down" events are not fired here because the flags
794     * checked here do not tell what exact keys are down.
795     *
796     * If one of the keys corresponding to a flag is down, we rely on
797     * -[NSEvent keyCode] of an event whose -[NSEvent type] is
798     * NSEventTypeFlagsChanged to know the exact key which is down, which has
799     * the following two downsides:
800     * - It does not work when the application is inactive as described above.
801     * - It malfactions *after* the modifier state is changed while the
802     *   application is inactive. It is because -[NSEvent keyCode] does not tell
803     *   if the key is up or down, and requires to infer the current state from
804     *   the previous state. It is still possible to fix such a malfanction by
805     *   completely leaving your hands from the keyboard, which hopefully makes
806     *   this implementation usable enough.
