I explained how C-x is handled as an example.

But the remapping is the elegant part of cua ---  in each
of the keymaps for the region, rectangle, and global mark
I simply remap kill-ring-save to cua-kill-region, cua-kill-rectangle
or cua-kill-to-global-mark ... ignoring the specific keybindings the
user may be using for kill-ring-save  (and copy-region-as-kill BTW).

Well, they define other bindings which are specific for cua's
handling of the region, rectangles, and global mark.
