Check out the Gesture shortcuts for Cyanogen11
Other gestures available include some for the music player. Use two fingers to make vertical lines to play or pause music. Draw a left arrow to hear the previous track (the one that played before the tune you currently hear) and draw a right arrow to skip ahead to the next track.
The gestures need to be enabled, which you can do by going to the Gesture section in Settings, and make sure that the ones you plan on using have been toggled on. It goes without saying that if you fail to enable a specific Gesture shortcut on your device, it will not work on your phone. Also, keep in mind that these controls may not be available to all phones using Cyanogen,
