It doesn't work like in CC.
You have default controls set to the behavior you are using.
For example using a platform behavior for your character, you will have a property "Default control" in the properties bar.
To change the controls, you have to set it to no, and then with a keyboard object you'd have first inserted into the layout/project, you intercept the commands.
I can't seem to find a good example showing right now, but you can see the technic used in several platformer examples of the how do I FAQ.
Edit: Of course, I jumped the obvious, the example folder.
Thanks Ashley.
