And the top comment is about Emacs. Yep, that's a vi post alright.
One of the reasons Emacs grew a fan base is that it had powerful features nothing else had. Sometimes decades before anyone else.
It's quite fitting as a vim using HAM (with a callsign username), that the top comment on that thread is also a HAM saying how you can also do this in emacs. The world changes all around us, and yet it's always the same.
