Shift <N>, Shifty

On Shift <N>, the first <N> parts of the call are skipped, the rest of the call is done, and then the <N> skipped parts are done. Shifty means Shift 1.

A Shift 1 Alter the Wave is:

Fan Back
Counter Rotate the Diamond 1/2
Flip the Diamond

This concept can become quite complicated when mixed with fractional concepts, Reverse Order, and meta-concepts.
