* *4: if no keys registered to host

* *6: only if no keys down
* *7: ignore Fn because Fnk key and stored key are down.
* *8: move to IDLE if layer switch(off) occurs, else stay at current state
* *9: repeat key if pressing Fnk twice quickly(move to PRESSING)
* *a: layer switch and process waiting key and code if code == wainting key, else unregister key
*
* States:
* IDLE: No key is down except modifiers
* DELAYING: delay layer switch after pressing Fn with alt keycode
* WAITING: key is pressed during DELAYING
*
* Events:
* Fn: Fn key without alternative keycode
* Fnk: Fn key with alternative keycode
* -: ignore
* Delay: layer switch delay term is elapsed
*
* Actions:
* Rk: register key
* Uk: unregister key
* Rf: register Fn(alt keycode)
* Uf: unregister Fn(alt keycode)
* Rs: register stored key
* Us: unregister stored key
* Sk: Store key(waiting Key)
* Sf: Store Fn(delayed Fn)
* Ps: Process stored key
* Ps: Process key
* Is: Interpret stored keys in current layer
* L+: Switch to new layer(*unregister* all keys but modifiers)
* L-: Switch back to last layer(*unregister* all keys but modifiers)
* Ld: Switch back to default layer(*unregister* all keys but modifiers)
