feat: Keyboard shortcuts

[snowystinger]

Closes

I think I've solved the chaining issue we had. By using chain, each handler is wrapped in it's own createEventHandler. This means that if any of the handlers or shortcuts call stopPropagation, it'll be stopped, same with preventDefault. They can't interfere with each other and the stricter behaviour wins. Stricter behaviour === stopping propagation and preventing of default.

In addition, I fixed a couple issues where I didn't quite translate the old behaviour correctly.
