ZOOM

        [GTVL\]ZOOM [Argument(s)]

    Without arguments, ZOOM calls the cursor to define a new viewing window.
    This  new  window will be defined by its center (at the cursor position)
    and a zooming factor (by steps of 1.414) :
       Z       Increase the zooming factor
       -       Decrease it
       0       Reset it
       E       Exits from the routine
    These commands do not produce effective zooming, press the space bar  to
    do  it. For X11 displays, you may use the mouse buttons for the commands
    <Space> (left mouse button), Z (middle mouse button), and E (right mouse
    button). Use ZOOM OFF to close the zoom window.

    ZOOM X1 X2 Y1 Y2 can  be  used to modify the viewing area of the current
    window.  The zooming does not affect the plot, but only the  way  it  is
    displayed.
