- There are many pre-designed templates and extensive libraries of images, sounds, animations and videos that make presentations easy to use and look professional. - Hyperlinks can be used to jump between slides, presentations, other software and websites. - Animation and visual/audio effects should be used sparingly to keep the audience engaged without being distracting. - High contrast colors and large, readable fonts should be used so the presentation is easy to see from the back of the room. Slide timing can be manually controlled or set. - Pictures should not be too large or irrelevant, as they distract from important information. The presenter can blank or white out the screen using keyboard shortcuts when they want full attention.
