Note: This tab is only available for pictures, text frames and AutoShape drawings.
On the AutoShapes tab, you can assign an AutoShape to the object. Thus you can turn a rectangle into a speech balloon or any other shape you like, for example.
To change the shape, simply click on the desired AutoShape in the list.
Tip: You will also find this option as the command Change AutoShape directly on the contextual ribbon tab Object. For more information, see Changing the AutoShape of frames.
For more information on AutoShapes, see Inserting drawings.
