I've been playing guitar since I was a little kid. I wonder how learning "two-handed" skills such as playing music impacts how "handy" or "polydextrous" one is. There are left-handed guitar players that play right-handed, such as Nick Johnston, who claim the gaps in their technique or preference for certain left-hand-only techniques are informed by being left-handed; so it seems that a life-long of an insane amount o…

It's like Super Mario Bros. With a 4-way d-pad and 2 action buttons, why is the more complex 4-way on the left? Because most of the time you're holding a direction first with less requirement for precise timing, and then pressing the button at the correct instant depending on the movement. (We're talking general platformer play, not hyper precise d-pad moves for something like Super Metroid speedrunning.)
Even typing on a keyboard, I never hold a right-side shift or other modifier key, it's always left-shift then the target key.
