I've seen some people suggest hitting the ctrl key with the 'side' of your hand instead of your pinky. I've found that using the bone directly below your pinky (towards your palm) also works (at least in my case), and is fairly comfortable.

I was inspired to do this by Aikido, where one of the techniques is a pressure-point application using the bones on the inside of your hand to apply specific pressure while holding someone's wrist in a grip.
