/**
* The justUp value allows you to test if this Key has just been released or not.
* When you check this value it will return `true` if the Key is up, otherwise `false`.
* You can only call justUp once per key release. It will only return `true` once, until the Key is pressed down and released again.
* This allows you to use it in situations where you want to check if this key is up without using a Signal, such as in a core game loop.
