*
* If a flag is not set, fire "up" events for all keys which correspond to

* checked here do not tell what exact keys are down.
*
* If one of the keys corresponding to a flag is down, we rely on

* - It does not work when the application is inactive as described above.
* - It malfactions *after* the modifier state is changed while the
* application is inactive. It is because -[NSEvent keyCode] does not tell
* if the key is up or down, and requires to infer the current state from
* the previous state. It is still possible to fix such a malfanction by
* completely leaving your hands from the keyboard, which hopefully makes
