Those keys are reserved? You've got to be kidding me.

Call me strange, but I've used the number key area of the keyboard for every single game I've ever played.

By reserving keys and not allowing them to be mapped, you're really destroying the entire point of keymapping, which is to allow users to make mappings that they prefer, not forcing them into configurations that you think are good.

Severely disappointed with this, it's just unacceptable. You've got to change this in a patch.
