I'm not sure there is a way to rebind those keyboard shortcuts, at least in Windows, since I believe they are all handled in the current program's Windows message handler as key inputs rather than cut/copy/paste events. So, afaik, it would need to be set up on a per program basis with that program's support.

There might be a utility that does that remapping on a key by key basis, but I figure such an app might not work as well with games that use ctrl as a modifier key but not for cut/copy/paste.

For Linux, most of the work I do there is via the terminal which doesn't even have the usual ctrl key combos for those operations (like ctrl+c is SIGTERM instead of copy).

If I'm doing something that is heavy on copy/paste and mouse use, middle click paste covers a lot and for what it doesn't, I can move my left hand to hit the qwerty period or I buttons on the right side of the keyboard, so this issue hasn't been enough of a problem for me to seek out a better solution. I've also got a two button switch keyboard layouts shortcut so I could just switch it to qwerty for that and switch back easy enough.

Though I did use to rebind those shortcuts in word and the like when qwerty habits were fresher in my mind. Thinking back on it, I'm not sure when it was that I "unlearned" those shortcuts.
