The TOGAF Toolbox Pages
The MDG Technology For TOGAF Toolbox pages provide elements and relationships for the full range of TOGAF diagrams supported by the Technology.
Access Diagram | Toolbox: More tools | TOGAF
When you open a TOGAF diagram, Enterprise Architect displays the Toolbox pages that are most useful for that particular diagram type. In addition, the Common and Artifacts pages of UML elements and relationships displays, regardless of which diagram is open.
The Diagram Toolbox pages can be docked on either side of the diagram, or free floated on top of the diagram to expose more surface for editing.
