[Feature Request] Web Version: 'e' button keyboard shortcut for next, customizable personal shortcuts?

It’d be cool if I could use the ‘E’ key as my shortcut for Next, together with the Enter key, because that way in lessons when I don’t need to type or use the mouse my left hand could do all the work without needing to change position. It makes sense ergonomically to me. We already have the ‘R’ key for repeating audio/video, makes sense to have E for Enter since they’re both close by.

Would be also cool if I could just select which button shortcut works for me instead of it being a universal shortcut for everyone.
