In MS word or ppt, if you click 2 hypens -- and then a space, it turns the 2 hyphens into an em dash. In google docs, you have to select substitutions and find the right dash (it's a pain, but you can do it). In Acrobat, I want to insert an em dash and I can't see how to do it, so I'm stuck using 2 hyphens -- and it looks very unprofessional.
