In your handout, starting on page 4, there is a list of many of the keyboard shortcuts available in PowerPoint.
Put a * next to the shortcuts you think you will use. Post this close to your workstation.
In the movie The Pursuit of Happyness, the main character Chris Gardner (played by Will Smith), figures out a shortcut of his own. By not putting the phone down he saved time. I have the same theory about the use of a mouse. Time yourself reaching for your mouse. How much time a day could you save by using keyboard shortcuts.
