We present a method for controlling the spatial properties of a high-order harmonic beam on a subcycle time scale. By adding a second-harmonic field to the driving laser field, we modify the spatiotemporal structure of the harmonic beam and manipulate it with attosecond resolution. Such a manipulation maps the subcycle dynamics of a recolliding electron to the spatial domain.
