Uses YouTube's HTML5 player and your mouse scrollwheel to control playback:
hold 'shift + wheelup / wheeldown' to 'jump forward / back' (seek +/- 5 seconds)
hold 'alt + wheelup / wheeldown' to 'speed up / down' (speed +/- 0.25 rate)
Works on both normal and fullscreen player.
A small text display will appear above the top-right of the video to indicate current playback speed.
