I found the use of the manual in electronic format an excellent teaching aid. I already have it open when I teach a class, so if I need to point out a certain paragraph or a particular exercise, students see it right away on the screen.

Not only it saves precious minutes, but it keeps the students focused on the task on hand, instead of having to ask questions and hunt for things in the manual.

Is anyone else doing something similar? What else do you do differently?
