Spell-check

"Some people might wonder why we still need copy editors when we have spell-check. Although it is a pain whenever I want to double a consonant before a suffix, per New Yorker style, and the spell-check prefers the no-frills version—“mislabeled,” say, instead of “mislabelled”—and I have to go back and poke in the extra letter and then put up with a disapproving red line under the word, I would never disable spell-check."
