That's not "cross-dominant", you are simply a lefty who has adapted to living in a right-handed world, just like me. I can't use a computer mouse or fire a gun left-handed, but only because they rarely made these things for left-handed people when I was growing up, so Ive only ever used then with my right hand and struggle to switch sides.

That said, my aim with a mouse and a gun are awful because I'm not right-handed. I have a feeling that I would do a lot better with these devices if I was more accommodated in my childhood.
