Hello Joseph, how do I know? I don`t know exactly, it´s too long ago
You should find that stuff in the Pro/E help. I can´t say exactly where because I use the german version. Try to look for "superscripted". There are some more things. For example: If you have a note with several lines you can move the leader to a special line if you write @o at the beginning of the line. You can use dimensions, symbols, geometric tolerances in notes, use different styles in one line etc. So it is worth to look into this subject.
