people actually use right-ctrl and right-shift? i forgot those keys even existed.

but why not just use the left-ctrl? it's as easy as can be: pinky on ctrl, index finger on x, they're the perfect distance apart, you press them in one fluid movement.

maybe I find this easier because I'm left handed?

My laptop keyboards don't have them, so even though I learned to use them, I'm picking up bad habits.
