In fairness, Emacs has long had cua-mode for rebinding C-c, C-v, C-x, and C-z to copy, paste, cut, and undo, so at least those changes are not too radical.

Agree with you. Coming from sublime and always wanting to give emacs a fair try, I found ergoemacs [0] that wanted to expand the cua mode for beginners, but that was not enough for me. I wanted more, and now with IDEmacs it is almost like what I want. With emacs you can do pretty much anything, why not a full cua mode ?

It was pc mode and then cua mode
