Have you ever used a typewriter?

Nay.

Couldn't have been much fun. I suppose anytime you made a typographical error, you got to rewrite the entire page on which it appeared?

As I said, I never suffered the gross misfortune of having to use one. But I don't see how white-out would help if you omitted a word or two. I guess you could white out the entire line and hope there is enough space in the margin—or white out the entire paragraph, and hope (in most cases, with more confidence) that there is enough space in the sum of the remaining margins.

In the above paragraph, the "in most cases, " and "remaining" bits were added at the end. I doubt it would be pleasant to make that change on a typewriter.
