With a vary minor addition, "Cycled" mode is working.
Both modes advance pole by pole, from first pole to last pole.
Then:
By push button, Cycled mode jumps from last pole to first pole. (delta = -5)
Or, By push button, Tic-tac mode reverses (delta = -1), from last pole to next to last pole, etc, back down to first pole.

Mode may be changed in the Info box.

Wire color is working.

"Final" version attached.
No plans for "Button" mode, at this time.
