Emacs cua-mode is not bad. It does create some confusion with C-x shortcuts, eg. C-x C-s when typed too slowly will cut selected text and enter search, instead of saving :-( But I'd love a more total conversion to CUA... E.g. I have C-o to open files, and C-w to close buffer/window.

-- emacs user for >15yr, tired of motor context switching. (Terminal Ctrl+Shift+X/C/V vs it opening devtools in Chrome is bad enough...)
