TIG,
Thank you. I don't remember ever hearing about that.
Although moving away from the edge, intersecting and moving the result back to the edge leaves segments that, if deleted, deletes the whole brown filling of the plane!
After deleting them and redrawing the right edge in two parts ending with the circle segment restores the fill with the hole breaking the edge, BUT, the hole in the center is filled in and not clickable for deletion. Mission sort of accomplished.

Deleting segments deletes the fill
Success: Sort of
