715     * the flag. Note that "down" events are not fired here because the flags
716     * checked here do not tell what exact keys are down.
717     *
718     * If one of the keys corresponding to a flag is down, we rely on
719     * -[NSEvent keyCode] of an event whose -[NSEvent type] is
720     * NSEventTypeFlagsChanged to know the exact key which is down, which has
721     * the following two downsides:
722     * - It does not work when the application is inactive as described above.
723     * - It malfactions *after* the modifier state is changed while the
724     *   application is inactive. It is because -[NSEvent keyCode] does not tell
725     *   if the key is up or down, and requires to infer the current state from
726     *   the previous state. It is still possible to fix such a malfanction by
727     *   completely leaving your hands from the keyboard, which hopefully makes
728     *   this implementation usable enough.
