Thank you - I don't think that would work for mum. It has to be simple - forward and back. not needing a lot of finesse until she gets more control. Besides, whilst I would be able to do the programming, at the moment we are spending a lot of time at the hospital (as much as they are allowing us - she is not out of the woods yet) which would be prohibative to doing it 'properly'.
I'll start looking for something for a different device.
