Editing an embedded block diagram

There are two ways to edit an embedded diagram:

      Open and edit the source file to which the embedded diagram is linked. When you edit a source file, all embedded diagrams linked to that source file are immediately updated to reflect the changes.

      Press CTRL+ALT+W to override the read-only status of the embedded diagram and make the edits directly to the diagram. To save the edits, make sure you execute File > Save Embedded.
