This event is fired when a Key is released, with the passed argument being the key that was released.


  • Not all keys generate this event. However, you can get around this with a few of the keys, “/” for example, by using the [[API:Class/Mouse/KeyUp|KeyUp]] event.
  • Some keys generate the same string as other keys.
  • It’s possible for the string to be empty (possibly due to “\0” key code).

Mouse KeyUp

The below example, assuming that ‘mouse’ was defined, would print the key that was released (e.g. “q”) along with the ascii value for that key (e.g. 113).
