28 years of vi and TIL about ZZ.

Thanks friend! ^_^

ZZ is the first vi command I learned. After typing vi and only seeing a column of ~s, I asked how do I get out of this thing. Someone answered - ZZ.

Did they say "zz" or specify [capital] "ZZ"?

I just learnt it the other day, as well. Granted, it was from chapter 1 of "Learning the vi and vim Text Editors" but shhh
