Got nothing to do with it. Computing wasn't invented in 1990.

Ctrl-c/v is a essentially a kludge introduced into Windows because the IBM Model M keyboard and similar didn't have a Meta key. It wasn't until Windows 3.1 that we see Ctrl-C and Ctrl-V being a 'thing'. Before then it was all about IBMs CUA. Apple had CMD-C/V/X on the Lisa 9 years before. I'm not sure what Xerox did on the Alto or if it even used keyboard shortcuts, but they did refer to the operation as Copy/Paste (coined by Larry Tesla who went on to work at Apple).
