== A little _vi_ twitch

I am not the world's most sophisticated user of vi, but I have a number
of little twitches. One of them is that I never use either _ZZ_ or _:wq_;
instead I always use _:w_ and then _:q_. I know the commands, but I just
don't like them for the fundamental reason that they're not vi commands.

Well, obviously they're vi commands in one sense. But they aren't in the
sense that they break [[the rules of vi commands LikingVi]]. Vi commands
as I remember them are single letters, both for 'action' commands
and for _:_ commands, and both of these fast-exit commands break the
rules. (_ZZ_ breaks them flagrantly; a doubled action command normally
applies to the line that you're on, whereas if _ZZ_ applies to anything,
it applies to the entire file. And of course there's no _Z_ command.)

(I expect that modern versions of vim have all sorts of multi-letter
commands. I ignore them, or more exactly I don't even go looking for
them so I have no idea which ones exist beyond _:set_. One of these
days I will actually find and read a complete index of vi commands,
but in the mean time I get by.)

These fast-exit commands may be convenient, but for me they are not
worth using precisely because they break the rules.  I would rather exit
from vi slightly slower and with more steps in exchange for preserving
vi's useful regularity in my mind and in my reflexes.

(I'm aware that I'm preserving an illusion, but it's a useful illusion.
By the way, this has nothing to do with vi versus vim, as both of these
commands were in the original BSD vi.)
