Professional speaker Fred Miller suggests when doing a projected presentation you bring a remote that:
- Advances and reverses the slide
- Adjusts volume
- Blanks the screen (turns off the light from the projector)
- Has an infrared pointer
- Is wireless RF (so you can stand in any part of the room and use it)
