To move inside the virtual image, HOLD DOWN your left mouse button and drag the 4arrow icon in the direction you wish to move. Hint: The 4arrow icon drives the virtual image slowly if held near the center of the picture. The closer the 4arrow gets to the edge of the picture, the faster the virtual image moves.

The 2arrow icon, which allows you to zoom in and zoom out, appears when the cursor is slightly above or slightly below the center of the virtual image. To zoom closer into the virtual image, HOLD DOWN your mouse button when the 2arrow icon is slightly above the center of the virtual image. To zoom further out of the virtual image, HOLD DOWN your mouse button when the 2arrow icon is slightly below the center of the virtual image.
