I was sitting with a client the other day, and I watched him carefully move his mouse up to the top left of his screen, click "Edit," and scroll down to "Copy." Then he navigated over to a new document, clicked "Edit" again, and hit "Paste."
It took him about ten seconds. When I showed him how to do the exact same thing in less than a second without ever taking his hands off the keyboard, he looked at me like I had just performed magic.
