Wrong - CUA's standard keys are Shift-Del, Ctrl-Ins, Shift-Ins for the
same operations. The alphabetics are not part of the CUA standard.
That said, though, most applications support both - primarily because
most GUI widgets are built to support both, and applications are
taught to respond to signals like 'paste'. This is one of those cases
where building your own is both way more work AND way less useful to
people; the same thing often happens when a program decides to be
"cute" with its UI and get rid of the title bar and regular frame,
painting its own window borders and stuff. It's a lot of work to make
that look decent, and then you end up with something that doesn't play
nicely with the rest of the system. You'd better have a really good
justification for that - and no, "it looks pretty" is NOT that
justification.
