Routing flows can quickly become very large. With a large routing flow, it is useful to add notes to the routing flow for informational purposes. Such notes might describe the functionality of particular parts of the routing flow, as an aid for future reference or to help other readers to understand your routing flow.
To add a note, right-click in the routing flow background and select Add Note.
To move a note around, drag it using the left or right mouse button.
To modify the note text, select the note and then make changes to the Information box in the Parameters pane.
To delete a note, either right-click on the note and select Delete or select the note and press the Delete key.
Note: Notes have no functional effect on the routing flow at all; they are merely for information.
