To run a slide show, select View Show from the Slide Show menu.
You can either let the show run on its own timings (see Slide show setup ) or manually move from one slide to the next using:
Mouse click move to next slide
PgUp move to previous slide
Esc end the slide show (or use the right-click menu)
Spacebar or PgDn move to the next slide
Use right-click and Pointer Options and set it to Pen to draw on a slide during a slide show (for example, to underline a point your making in your commentary). Switch the pen off using the right-click menu.
