Some hidden commands for your Ipod

I know some of the readers here are proud owners of an Ipod (and why wouldn't they be) so I thought I'd share some information I stumbled across that may come in handy. I don't know how useful or relevant these are, I haven't had a chance to try them out on a Ipod myself, but thats where I am asking readers to post the results of their experiments. The original post was from Comman-Tab, there is considerable discussion here. Happy commanding!
