Unless no slides exist yet, one slide is always marked as the ‘current’ slide, indicated by a checkmark in the lower left corner of the slide. A storyboard has only one current slide at a time. To select the slide (which also marks it as current), click the slide.
You can rename slides only in Authoring Mode.
To give a slide a more intuitive name:
You can also right-click the slide and select Rename from the menu that appears.
Change the duration of a slide
You can change the duration of slides only in Authoring Mode. At a minimum, a slide must be long enough to allow its final shot to complete.
To change the duration of a slide:
You can also right-click the slide and select Change duration from the menu that appears, or change the duration in the Slide Properties window.
Create a snapshot icon to easily recognize a slide
You can create snapshot icons only in Authoring Mode.
To make it easy to see what’s in a slide:
You can duplicate slides only in Authoring Mode.
To duplicate a slide, right-click the slide, then select Duplicate. The slide is inserted to the right of the slide you clicked.
You can delete slides only in Authoring Mode.
