P.S. I wonder what the guys fifty years from now will say, when they
have been "raised up" using jog buttons and jogwheels, instead of the
handwheels WE began with??? I really do believe you "feel" its
faster because you have been "programmed" by your experience to
believe so, and therefore it IS faster for you! Notice I'm not
disputing your claim to doing some things faster by hand control;
just wondering if you'd feel the same if all your past experience
was "cut by wire"???
