2000 Windstar CD player?

so i bought a used windstar a few weeks ago and it has a cd/cassette player. I cannot figure out how to change the song on the disc player. You know, track 1, to track 2 etc. Anyone know how to do that? I feel so silly that I cannot figure this out!

Use the seek control on the left side of radio to go forward or backwards within a cd.
