The Mouse is the button that is mainly needed? they keyboard is needed only on rare occasions.
Click on the Track you would like to open and listen to.
The first two buttons on a song move it up and down in the track, the third one mutes the specific song.
The pause button for the entire track is at the top, somewhat in the middle.
Everything else should be rather easy, I hope. If not, let me know, and I will address it if I can.
Thanks for your patience =).
