Glad it made sense and worked. I usually need a visual cue, so YouTube videos and blog tutorials with images really help me. I learn so much here myself - happy to share anything I do actually know.

One thing - if other people are working on the same documents as you, you might want to make sure they have "show bookmarks" turned on in File/Options/Advanced (it's checkbox under "show document content" there), so they realize where the bookmarks are and don't type or backspace them out. Been there, done that.
