If you need to reference a trademark in MS Word, such as Gizmo(tm) or Gizmo(R), there are two ways to do it:
1. After the word that needs a trademark, type open parenthesis, t, m, and close parenthesis. MS Word will automatically format the tm designation with a superscript. You can do the same thing to get a registered trademark, type open parenthesis, r, close parenthesis. MS Word will automatically format the r with a circle around it, superscript, etc.
2. You can do the same thing in MS Word by holding down the control and alt keys along and then typing tm or r.
