I've been using Emacs for about 20 years, and whenever I found myself on a headless or embedded system, I would fumble along in vi using h,j,k,l,w,q,i,x, and a. The bare minimum. Spending a couple days getting more elaborate commands under my fingers ('cw', 'dt)' has been totally worth it. I could have saved dozens of hours over the years if I'd learned the commands earlier.
