Remember Correction Ribbon?

When I learned to type I was terrible! I am not so great now, but between Spellcheck and the backspace button, I survive, lol! I had to use White Out constantly. But then I got a typewriter that had the correction ribbon! It was so easy peasy - just backspace, hit the key that typed a white letter over the mistake, hit backspace AGAIN, and type the correct letter. Five hours later and the term paper was finished! :P
