869     *
870     * If one of the keys corresponding to a flag is down, we rely on
871     * -[NSEvent keyCode] of an event whose -[NSEvent type] is
872     * NSEventTypeFlagsChanged to know the exact key which is down, which has
873     * the following two downsides:
874     * - It does not work when the application is inactive as described above.
875     * - It malfactions *after* the modifier state is changed while the
876     *   application is inactive. It is because -[NSEvent keyCode] does not tell
877     *   if the key is up or down, and requires to infer the current state from
878     *   the previous state. It is still possible to fix such a malfanction by
879     *   completely leaving your hands from the keyboard, which hopefully makes
880     *   this implementation usable enough.
