For some reason, when right-clicking on a new path within the PATHS tab,
the "Duplicate Paths..." selection is greyed out, and it seems like nothing will make it light up to be usable.
The solution: ... The problem was that this was the first path created by some other means, and it was labeled "Work-path". Double clicking on its label: "Work-path" allows one to change it to something else. Once its been renamed, then the "Duplicate Paths..." tool will light up, allowing for a duplicate to be made.
