Adding a Note with a Leader
To add a note which specifically points to something on your one‑line, click 
Note with Leader from the Equipment Palette or Insert tab. Hold the left mouse button to set the leader's pointing arrow at the target location, and drag to the location where you want the note outline box. You can drag and resize the note's outline box later as described in Dragging and Resizing a Note.
When this type of note is selected, you will see an additional handle at the tip of the leader's pointing arrow. You can drag this handle to change the location of the pointer.
