@b0rk Also, two notes:
* I'd add `ctrl-K` (clear to end of line) to the list of "very useful" readline keystrokes. I type `ctrl-A ctrl-K` all the time to clear the line. (Although apparently that's because I don't know about `ctrl-U` 😂
* Weirdly, a lot of the emacs movement commands work in arbitrary text areas/inputs in MacOS 🤷
