@DelilahSDawson Note to self: When you change the char's name from Tom to Jimbo with a blanket Find & Replace, you get a lot of Jimboomorrow.That tweet from Delilah made me remember a story I meant to tell you guys!
So one of my clients wrote a manuscript. At a certain point, he decided that the "trolls" in the book should really be "elves"... and the use of Word's "Find & Replace" feature created some hi-larious mistakes.
Characters found themselves "selfing around" instead of strolling. Trolleycars because "Elfeycars". A plate of sweetrolls became "sweeelves" - and you need a lotta coffee to wash those bad boys down, believe me.
These mistakes did not get caught until the book was almost printed, because, though they were all changed in the first pass, there was a mix-up with the versions. Whoopsie! So if it wasn't for some late-breaking intervention, there was a very real possibility that you'd have been trying to work out a good recipe for sweeelves while reading this book.
The point I am making might sound silly, but it can't be repeated often enough: Those little shortcuts and conveniences the computer lets you take with your manuscript can be handy and great, but you'd better not take for granted that they've worked properly. And when you think you are done re-reading, try taking a break, and re-reading again.
ETA: My sister sent me this episode of Radiolab- the first segment discusses innocent copyediting errors that lead to bigger unexpected problems. (Funny... but not for the person who loses their job over it)
