Duplicate an Edit Pin?

Right-click on the pin you want to duplicate and, from the pop-up menu, choose Duplicate (as seen above). This duplicate will appear directly on top of the original, so it’ll look like nothing happened, but if you click-and-drag right on the edit pin you duplicated, you’ll see you’re dragging a copy off to a new location without disturbing the original. Another way to do this is to press-and-hold Command-Option (PC: Ctrl-Alt), click on the pin, and drag it wherever you want it.
