When I first learned to type it was on one of those old manual typewriters with the "ding" at the end of each row to let you know when to push the return carraige bar for another line. Those stupid little eraser pencils always ripped the sheet of paper (that was even before white-out!). When you put "cc" at the end of a memo or letter it didn't just mean "copy to someone else" it stood for carbon copy. We didn't use xerox machines or computers of course so we had real carbon paper to type two copies at once
