Looks great.

Related story. In late 2010 a client asked me to write effectively the same thing for him as a Mac app, using that one protocol I can't remember the name of, but which had promise and never quite caught on. All I can remember about it is that I implemented JavaScript's `for await (...)` in 2010-era Objective-C, and I felt like a genius because I had never even heard of such a concept before, and came up with it on my own just to solve a problem in that project. That function worked amazingly and only took like 100 loc or something. I wonder if he still has that source code around somewhere.

Did things change? We used to use "responder chains" to do this. In fact that concept was created to avoid having to subclass for keyboard shortcuts.
