Hi Ulodesk. You're right, thanks for mentioning that. Sometimes it's necessary in that step to replace with a space, though not always. I've seen it both ways.

I never do a whole document at once. Usually I do a few paragraphs at the beginning until I see how it's going. As I get more comfortable I'll do larger sections at a time but it's still a good idea to keep checking. I've seen some documents change several times.
