From a Line or other applicable 4-dancer formation.
Centers Step Ahead as Ends Run into the adjacent Center position.
Ends in either a Box (2 x 2) or a "Z" (4 spots within a 2 x 3 Matrix).
Step & Flip is similar to 
  Step & Fold [C1]
  except that on a Step & Flip the original Ends always finish holding
  hands with each other.

Notes:
- 
From a Wave, Step & Flip ends in a "Z" whereas
    Step & Fold
    ends in a Mini-Wave Box.
- 
The 'Step' of Step & Flip is a step ahead, which often (but not
    always) is the same as a Press Ahead.  'Flip' means Run into the
    adjacent position (as in Flip The Diamond).
- 
Unlike 
    Step & Fold,
    Step & Flip can be done from any line of 4.
    Upon completion of the call, the original Ends are adjacent to each
    other.  From Parallel Lines, Step & Flip is done in each Line, and
    nobody crosses the center line to the other half of the set.
