As you can see, that didn't work. And for what it's worth, Safari doesn't seem to have the "find and replace" feature we all used so much back in the '80s and '90s in word processing programs. (Yes, maybe I could have changed this to Word and tried to do just that, but I am too lazy.)
What happens--which I think is very weird--is that copying and pasting the text changes SOME, but not ALL instances of the letter "e" in the text.
Any suggestions? That article doesn't matter a great deal, but I've seen it happen in other posts.
