Commandline options  

U/V/N 
Moves a control point in the u, v, or normal direction. 
Scale 
Sets the scale of the sliders. The clicker arrows jump the current number by an order of magnitude. 
UV Move mode 
Along tangentThe u and v sliders move the points in a plane that is roughly tangent to the surface. Along control polygonThe u and v sliders move the points along control polygon chords. Along extensionsThe control point will move along the imaginary extensions of the control polygon. U Symmetry / V SymmetryMakes it possible to edit two sides of a symmetrical surface at the same time. You must select all points to edit. 
Smoothing U/V 
Use smoothing before MoveUVN to make it possible to combine the actions. Smoothing tends to even out the control point grid, and the other controls can be used for making small changes to the shape.
