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.

Start by reviewing the current slide show to identify an existing slide that needs a caption, then consult the Appendix in the training manual if needed. Add one or two captions to the selected slide and confirm they appear in the slide show.
