I've been using vi variants for decades and didn't know ZZ or ZQ. This solves a major pain point for me (mis-typing :q, trying again, now I'm off in the weeds).

ZZ is particularly nice since it sorta "does the right thing" in that if you have an unwritten empty buffer, it will silently discard it and quit. I guess I haven't really run into this as I was taught ZZ from the beginning but I imagine hitting :wq<cr> on such a buffer is pretty annoying.

The worst part is q: is a different command. so if you are trying to :q and miss the colon and try again, you run some other damn f*cking command.
