Do you even use two hands for shortcuts like copy and paste?

I use ctrl-c and ctrl-v for those. Right hand presses right control with palm of hand (just below pinky). Left hand types the letter like normal.

I just kind of roll my hand to the ctrl key, I don't use a finger to press it.

Same thing with right-ctrl.

Yes. And even considering the locations of C, X, and V on the QWERTY layout, I wouldn't type Control with any of those with one hand.
