I'm not going to argue that emacs if "for everyone" and there's plenty in my own life that I'm happy to accept defaults in. But that said, it's not that hard to glue emacs onto existing tools if needed.

On MacOS, Apple script does wonders and for Windows there's AutoHotKey. Linux obviously is infinitely malleable.
