Simple modification of the electronics of a STM allows operation in various tracking modes. Profiles of steepest inclination, equal height, equipotential, electrical field lines, etc., can be traced out. The tunnel tip can also be locked to a surface extremity for indefinite time. Some of these possibilities were tested experimentally.
