Right clicking an object to obtain and modify its properties goes back to Windows 3 at least. Once you have remembered that little "trick" you have learned how to perform thousands of different tasks on different objects. It is a "trick" with a big pay-off, which tends to help people to remember them. Even then, I doubt more then 50% of daily computer users even know what a right click does, Start Button or not. Good gracious I don't want to start an Apple v. PC war, but it is something that Apple had to be dragged kicking and screaming to embrace.
