How do I create a playlist on the go?

[full frontal messiah]

My mom wants to finally listen to a play list on her Zen V Plus, rather than listen to all of the tracks continuously. I know how to add music to Now Playing but how do I remove the original contents from the Now Playing screen so her play list will be the only thing showing? Also, how do I save the selected music as a play list?
