explain the usage of the rehearse timing option of presentation software
Answers
Answer:
While you rehearse, use the Slide Timing feature to record the time that you need to present each slide, and then use the recorded times to advance the slides automatically when you give your presentation to your actual audience. The Slide Timing feature is ideal for creating a self-running presentation.
Answer:
When you want to record a running time for each slide, use the Rehearse Timings feature. This enables you to run through your presentation in Slide Show view and record the time each slide takes. Then, use the timings to run the show automatically, either to help you rehearse, or for a self-running show.
