COMMAND NAME:

        MARKER

USAGE:
        MARKER OFF
        MARKER ON <time>

        This command causes a vertical cursor to be placed on the screen
        at <time> with corresponding value at its intersection with 
        waveforms to be displayed at the right hand edge of the screen.
        <time> can be entered from the keyboard or by using the LEFT
        MOUSE BUTTON. Marker snapping to the nearest edge is toggled
