How does the navigation work on an iPod Shuffle?

[BentValve]

I'd like to get a small MP3 player for my mom for Mother's Day but I need one that is easy for her to use. The iPod Shuffle is small and cheap but I have never used one before. Would somebody please explain to me just how the navigation thru the albums and songs work on an iPod Shuffle?
thanks

It talks to you and tells you where in the menu structure you are.
