Touch typing: what is the best way to press key combinations? Two hands or one, if possible?

Question

Keyboard

A question for those who have been using blind dialing for more than a year.
I am now switching to touch typing, everything is fine. However, the question remains, how best to press key combinations. The same banal ctrl + c, ctrl + v.
How do you press key combinations: always with 2 hands or one, if possible? And, if the latter, what combinations with two hands, and which with one (curiously)?

Answer 1

When printing with a shift - different.
Copy-paste ctrl + c, v, x - with one hand, left.
