Change the Image comment

How do I change the image comment in the D70 menu? I cant seem to find a way to delete or backspace?
I also cant find anything about this in the manual.
This is im sure is a simple thing to answer from seomone who knows and I will probably slap myself as soon as the first person responds with the answer.
So please.. make me slap myself
