Map command key to caps lock. Setting

(global-set-key (kbd "M-P") 'scroll-down-line)

(global-set-key (kbd "M-N") 'scroll-up-line)

Has also been indispensable for scrolling (though you may choose to do so differently, coming from vim).

Hear hear. Ctrl on caps lock changed my life. Then I bought a TECK^, which comes with a split spacebar and put left alt on caps (or where caps is usually, teck has control there) and right control on the right spacebar. This is honestly the best setup ever and I don't even use Emacs, I use Vim.

^ truly ergonomic computer keyboard. It's nice, but the hardware can be a bit wonky.

I forgot about that. Caps lock is useless 99% of the time and having that control available easily with your left pinky makes emacs (and everything else) work.

I'm so confused when I get on other people's computers and caps lock is actually caps lock.

Since he is looking at spacemacs, I'd recommend mapping caps lock to escape when it's tapped, but ctrl when it's pressed in conjunction with other keys. Very useful,

(though I suffer from the same problem when on other peoples computers)
