This differs from one man to the next, as well as by specialty. Some people work better by typing out code quickly, permuting it several different ways, and coming up with a final revision. On the other hand, I sometimes spend ten minutes staring at my screen, then bang out ten lines of code that get something _just right_. However, someone who's more devops/sysadmin focused might type more, as he's piping lots of tools together to filter the output of something, at least from my experience.
