Set operations allow sets to be created, destroyed, written to disk, sorted.
Reverse order Coalesce sets Swap Pack Pick ops Pick ops use the point in a set nearest to the location of the pointer when clicked to select the set for the chosen operation. The nearest point is determined by the Euclidean distance which can be very different from the point that is visually closer. As long as there are sets with points, the operation will always be performed, which means that a bit of care should be exercised using these operations. Kill nearest set Kill the set nearest the pointer. Copy nearest set Select a set to copy with one click, and the destination, which may be in another graph, with another click.
