Use captions to create labels, speech bubbles, and thought clouds. Here's how to add captions in Articulate Storyline:

  1. Go to the Insert tab on the ribbon, click Caption, and choose a caption style.
  2. Click and drag on your slide canvas to draw the caption to your slide.
  3. If you want to add text to the caption, select it and begin typing. You don't need to add a separate text box.
  4. If the caption style you chose has a pointer, you can make it point anywhere on your slide. Just click and drag the yellow handle at the end of the pointer. 

The default fill, line, and text colors are controlled by your theme colors. To format a caption with different colors and effects, use the tools on the Format tab on the ribbon, or right-click the caption and choose Format Shape or Size and Position.

Tip: If you format a caption and want that same formatting to be used on new captions in the same project, right-click the caption and choose Set As Default Shape.
