I found a first edition copy of Learning GNU Emacs at work. I've started reading it just to see how much of it is still relevant 27 years later. I'm not through the whole book yet, but so far all of it still applies. ALL of it.
There's more to do with #emacs these days, but holy cow that is cool that it's still pretty much the same editor it has always been.
@adw That saves a lot of time. Learn the editor once and it's good for decades.
