How to skip around in the middle of a presentation
One of the advantages of the acetate slide era was that it was easy to call up the particular slide you wanted at a particular time. With PowerPoint a lot of speakers feel they need to click through all their slides to get to a particular slide. There is a better way.
1. Hit the slide sorter command on your presentation. You'll see the slides along with their corresponding number (the numbers are a little hard to see on the figure below, but they are just below the lower left corner of each slide).
2. Take a screen shot of your slides (cmd-shift-4)
3. Print out the screen shot and take the printout to your talk
4. At any point in the presentation mode, you can enter the number of the slide on the screen shot, hit return and you will get right to the slide
