ARROW KEYS (left and right) to skip backward and forward 5 seconds, but there will be a bug if this is done while the video is not playing. SPACEBAR to pause and play the video. SPEED modifier is in the bottom right corner.
This is a Scratch project I published a few months ago. Now you can rewind, fast-forward, restart, change speed... almost everything a YouTube player can do! With one downside, there is no sound :( I am working on how to fix this problem, and already thought of a solution.
