825 * the application is inactive (i.e. no events fire) and we don't want to
826 * wait for another modifier state change to detect such a change.
828 * NSEventModifierFlagCapsLock requires a special treatment. The other flags
829 * are handled in similar manners.
831 * NSEventModifierFlagCapsLock
832 * ---------------------------
834 * If CapsLock state is changed, "up" and "down" events will be fired in
835 * sequence, effectively updates CapsLock state on the guest.
840 * If a flag is not set, fire "up" events for all keys which correspond to
841 * the flag. Note that "down" events are not fired here because the flags
842 * checked here do not tell what exact keys are down.
844 * If one of the keys corresponding to a flag is down, we rely on
845 * -[NSEvent keyCode] of an event whose -[NSEvent type] is
846 * NSEventTypeFlagsChanged to know the exact key which is down, which has
847 * the following two downsides:
848 * - It does not work when the application is inactive as described above.
849 * - It malfactions *after* the modifier state is changed while the
850 * application is inactive. It is because -[NSEvent keyCode] does not tell
851 * if the key is up or down, and requires to infer the current state from
852 * the previous state. It is still possible to fix such a malfanction by
853 * completely leaving your hands from the keyboard, which hopefully makes
854 * this implementation usable enough.
