Good place for a comment?

The onKeyDown function is really interesting - I notice you plan to mention it in the presentation, which I'm looking forward to because tbh I don't get it. It might also be good to include an explanatory comment for yourself six months down the line.

^ I need to get better at leaving comments. All too often I just delete them and don't think about how James in 3 weeks time is going to deal with it when looking over the codebase.
