Hi guys

This one is sending my brain a bit awry.

I want to create a very simple form, which one question per page and I would like the user to be able to choose an option by pressing a number key. The question will be:

How useful did you find the service? Use the number keys to select an option.

1. Very good
2. Good
3. Ok
4. Poor
5. Very poor

Thus if they hit '3' they would be selecting 'Ok'. Is this possible?
