Move Brushes

From ZBrush Info

In addition to several new Move brushes, ZBrush offers now new behaviors while dragging the polygons with the Move brush:

Press the SHIFT key to slide the stretched polygons along the surface. As an example, you can easily pick the corner of the lips and slide them along the cheeks. Press the ALT key to do the deformation along the average normal of the surface corresponding to the brush size like in ZBrush 3.1.

Note: You can use the Brush Imbed and Depth to affect the form of the Move brush while using these shortcuts.
