781     * NSEventTypeFlagsChanged to know the exact key which is down, which has
782     * the following two downsides:
783     * - It does not work when the application is inactive as described above.
784     * - It malfactions *after* the modifier state is changed while the
785     *   application is inactive. It is because -[NSEvent keyCode] does not tell
786     *   if the key is up or down, and requires to infer the current state from
787     *   the previous state. It is still possible to fix such a malfanction by
788     *   completely leaving your hands from the keyboard, which hopefully makes
789     *   this implementation usable enough.
