There are a load of ways to move around in vim.
The first things you learn (
l) generally aren’t that efficient.
/ (buffer search) &
f (line search) are usually better.
On top of these, there’s a handful of other, lesser-known commands:
z commands (also used for folding)
zz move current line to middle of screen
zt move current line to top of screen
zb move current line to bottom of screen
Moving over lines quickly
ctrl-e move up 1 line
ctrl-y move down 1 line
ctrl-u move up 1/2 page
ctrl-d move down 1/2 page
ctrl-b move up 1 page
ctrl-f move down 1 page
