Edube Shortcuts von Alex Radomski

The provided combinations are shared across some other educational websites, eg boot.dev.
Upon testing, they seem to work across different courses without interfering with the normal functionality of Edube.

Edube's Next and Prev buttons seem to always be <a> elements with "Next" or "Prev" contents. They seem to be unique elements of each page. As long as these two things stay the same, the addon will continue to work. The Play/Run button has its own id which seems to stay the same across the board, so the addon targets that.
I hope OpenEGD will implement this functionality themselves at some point.
