With the advent of mice, many of these keyboard shortcuts fell by the wayside. I know that sometime when I tell people to "ctrl + c" or "ctrl + v," I get a toe-headed look in return.

"Windows keyboard shortcuts are all intended to provide some sort of convenient alternative to common tasks, and whether specific combinations do so is up to the individual to decide. Some are simple time-saving motions, while others are complex maneuvers in finger gymnastics."
