KILL

        [GREG3\]KILL

    KILL calls the interactive cursor to interact  with  the  current  IMAGE
    buffer.  The  buffer must have been loaded in write mode (IMAGE /WRITE).
    Recognised keys are:
      - V to give the value of the pixel,
      - K to give the current blanking value to the pixel,
      - I to interpolate the value from the neighbour pixels,
      - E to exit from interactive cursor mode.
    Any other key is ignored.
