It was recalled that the drift of adatoms strongly influenced the so-called wandering of an isolated step which moved within a surface-diffusion field. When the drift velocity had a component which was opposed to step motion and which exceeded a critical value, a straight step became unstable to long-wavelength fluctuations, and wandered. This wandering could be controlled by changing the direction of drift. When the drift had no component parallel to the step edge, the unstable step obeyed the Kuramoto-Sivashinsky equation and had a chaotic form. When the drift had a component parallel to the step edge, the step obeyed the Benney equation. If the parallel component was sufficiently large, the step had a regular form.
