Stop/start the "Move with arrow keys" function

I haven't gotten far enough in my production to actually test this, but before i get there i want to know if there is a way to stop and start the "Move with arrowkeys" function? I'm creating a game, and i want to be able to have cutscenes

Thanks

I don't know of any way to disable events in real time - they seem to always be active when the world is running.

You can disable mouse control of an object wile a world is running by setting it's "seldom used" isFirstClass parameter to false. This doesn't seem to work for arrow key control, however (see attached).
