How did you learn vi?

1) vilearn
2) vimtutor
3) Documentation (faggot)
4) Other

learn? I've been using this for 15 years as a programmer:

a
i
x
y
p
dd
dw
/...
:/...
:%s/.../.../g
CTRL-w
ESC
:
:<NUM>
:e
:w
:q
:wq
:q!

That's it!

Just recently I learned I could do gI on the pattern match. Note that I once knew how to escape tricky characters in the regex, but I've forgotten how to do that by now.

Sometimes I use hjkl; for navigating, but I always get it wrong, so I rather use the arrow keys.

15 years I tell you...
