Editor > Annotation > Duplicate Annotation

Duplicating is copying and pasting in one step. You can only duplicate annotation items within a Graph window.

Duplicated items are placed 20 pixels down and 20 pixels to the right of the current item. In the graph below, an arrow was created using graph annotation tools.

Rather than recreate the arrow manually for three other points, use the Duplicate Annotation function, then rotate and move the arrows into place.
