How to interchange the behaviour of the Keys

[anda_skoa]

But the problem is i am unable to see change in the behaviour of the keys, is it possible to do so.
i.e if is press on uparrow the cursor should move downwards and if i press on downarrow the cursor should move upwards this is my required output.

It might make sense to read all of the responses, some might contain additional input.

Cheers,
