Better Play, Pause and Rewind controls via Web player

So since playing content via the Web Player on my computer has gotten better with the latest beta I’d like to request better controls via a keyboard like YouTubes does please.

Pause = Space bar

10 sec skip back = Left arrow

30 sec skip forward = right arrow.

If this can be done or anyone has a hack for Google Chrome.

Right now For me these buttons do nothing or are very inconsistent.
