Because I love to share: Have you ever used the formatting paintbrush? I use it as a shortcut all the time, particularly after I cut and paste between Word and other documents.
I just discovered you can toggle it. Double-click on the paintbrush, and it keeps the last format you clicked in.
Wish I’d discovered this years ago.
Toggle it off by clicking on the paintbrush again, or hitting the escape key. (The Escape key is your friend. First one I go to any time I want some kind of annoying MS feature stopped.)
