I have difficulty believing such studies, especially since I could copy & paste files in Windows Explorer, using the mouse right-button shortcuts, ever since my parents got me a computer in 1995. I also do not live in the Valley or in the US for that matter, and having non-technical friends down here is the norm, rather than the exception. I have never seen one that could not cut/copy/paste files in Windows Explorer.

The only thing I noticed is that some people don't understand the difference between "cut" and "copy", or why the mouse drag&drop sometimes produces the former, while other times it produces the later. But these are separate things entirely that can't be solved by ribbon shortcuts.

Having worked at a library providing computer tutoring and assistance, I can absolutely believe such studies. You say "using the mouse right-button shortcuts" - the vast majority of people don't know these exist, or if they do, no idea how to use them (or what a "context-sensitive" menu is). When I guide my grandmother through something over the phone, I often have to specify whether she needs to click or double-click something - which I find so obvious now as to not even think about. Go figure.

Yes, but can your /parents/ copy & paste? Mine use computers but barely understand files. Folders are beyond them.
