I might be a perfect complement to the grandparent.
I use w b $ and ^ to move horizontally. I like using w and b because then I can hit cw to make a small change. For vertical (I don't really think in terms of horizontal and vertical, I think about it as a streams of "words" and "spaces") I usually do a search (/ or ? to go up or down) or for some files I do 20j like you. Shamefully, I do sometimes use the mouse out of habit from other programs.

I can't remember the last time I used f.
