Add summary slide
Create a slide with a summary of your selected slide titles (or all of them), to ensure your storyline makes sense. This can be used as a table of contents, as the basis of an executive summary or just added as a temporary slide for an editorial review.
To select all slides, Ctrl-A in the slide selector.
