Permuting
The option v will exchange planes, exchange and complement, exchange half-CAM 's, and so on. The exact list is:
0 - complement plane 0 1 - exchange planes 0, 1 2 - exchange planes 0, 2 3 - exchange planes 0, 3 c - cyclic permutation C - anticyclic permutation x - exchange evens, odds X - exchange CAM-A , CAM-B
l - longer cycle: ``Dabc''
As more and more demonstrations and specialized submenus have been added, the use of this option has declined.
