Group shape
Annotations and placeholders
You can use the Group shape as a placeholder for functionality yet to be added, or you can use it to make annotations about what actions take place within it.
The name property on the Group shape can be up to 512 characters long. You can type annotations into the Name property and, when the shape is collapsed, the entire name will be displayed. When the shape is expanded, the name is truncated.
