Zooming In and Out of the Display

Zooming enables you to magnify (zoom in) or shrink (zoom out) the display.
To zoom in or out, first click the button so it appears depressed.
To zoom in (magnify), place the cursor on the display and click the left mouse button. The display will be magnified 1.5 times and centered at the clicked point.
To zoom out (shrink), place the cursor on the display and click the right mouse button. The display will be reduced by 1.5 times and centered at the clicked point.
Another way to zoom in is to press and hold the left mouse button, drag the curson to draw a rectangle, and then release the mouse button. The drawing is magnified to fill the rectangle.
To zoom out to the unmagnified view, hold down the "Shift" key and click on the drawing with the left mouse button.
