Add a Caption To an Existing Slide

## Can you think of a better caption?
Each slide can have more than one caption. Check out the current slide show and add a caption (or two).
If you need help, check out the Appendix in the training manual.

Open the current slide show and inspect how existing captions are represented. Use the Appendix in the training manual if needed, then add one or two captions to an existing slide. Done means the new caption or captions appear in the slide show.
