You use your pinkies and there's barely any movement.

  Just as much movement as hitting any other key. Plus slightly more because you have to keep it held during the next key. It's really easy to do, but it's still more than double the effort of hitting a single letter, and when you're hitting many keys per second that makes a difference. Shift, letter, unshift is great for a single capital letter, but if you're doing that several times in a row then capslock is a lot simpler. As is holding a single shift, if you're used to it.
