This switch puts in action the fine regulation to 16 pure bit of the tables; when it is activated, every time I give a click with the mouse, the value raises or diminishes of a low bit.

Many times a single point of shifting is not enough; in that case keeping pressed the shift and giving a click with the mouse, the shifting is 20 byte low for every click.

This value of shifting can be changed in the square of lift and let the plane down.
