Changing the Adjustment Method for the BΘzier Interpolation Option
To change the adjustment method for the BΘzier interpolation option:
  Alt+click (Windows) or Option+click (Macintosh) the direction handle.
Each time you do, the adjustment method cycles to the next adjustment method: symmetrical, asymmetrical, and independent.
For example, suppose you make an adjustment using independent direction handles, and then move the cursor away from the keyframe. To continue using independent direction handles, click the direction handle and make further adjustments. To change the adjustment method from independent to symmetrical, Alt+click (Windows) or Option+click (Macintosh) the direction handle.
