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