The collaboration2.0 diagram offers a special context command, named New with a submenu for adding new elements to the diagram:
The New command for the collaboration diagram offers a submenu with the following additional options:
Choosing Part adds a part element to the diagram.
Choose Collaboration from the submenu to add a collaboration element to the diagram.
Choose Collaboration Occurrence from the submenu to add a collaboration occurrence element to the diagram.
Choosing Note adds a note element to the diagram.
