Steps to reproduce the problem:
No problem, other than this should already be a thing.

What is the expected behavior?
When you are in the mp3/audio player, you should be able to press the Forwards Page button for fast-forwards, Page Back for rewind, Reload for toggle repeat, and maybe fullscreen for shuffle or show menu.

What went wrong?
Nothing.

Did this work before? N/A
