Thanks for your reply. (Deanna Nichols is the subject of the profile: I am Dwight Childers.)
I highlighted the phrase "Her Obituary" (already italicized) in the bio and then clicked the bolding tool just above the editing box. It proved in the "Preview" but was not recognized as a change and thus not actually saved.
Earlier, I had italicized the phrase using the tool bar, but the end result is the 5 apostrophes describing in the Editing Tips.
Just now, I tried deleting an extra space from the bio. That was recognized as a change and saved, and now I see that "Her Obituary" is both bold and italic as I wanted.
Can it be that the change process does not recognize a Toolbar action alone?
