This is for my geeky friends, the only kind who will understand.
I found this here.
I’ll long remember (I no longer say, “I’ll never forget.”) visiting Peter Reintjes in Apex, NC, with a couple of more advanced CS students from UNC. One of them, Mike Peek (sp?), showed me some tricks with vi (the predecessor of vim). I couldn’t believe my eyes when he showed me what a period could do in vi! I consider that the most useful command of all.
I use vim to write almost everything in markdown. This post, however, is written in nvUltra’s editor.
