Thanks, but I’m afraid that the shift first-to-last option doesn’t work for me, because I also have dozens if not hundreds of footnotes. I don’t see any way to select-all for comments only. Even the “find” by format option only lets you cycle through comments, not select them all. Is there another option?
(And yes, I know how about selecting multiple comments. But since I have dozens, spread out among often 200+ footnotes (I write law review articles), this is very painful to do.)
