4. Navigate in the image by: 

    • Zoom in: Moving the mouse scroll wheel forwards.
    • Zoom out: Moving the mouse scroll wheel backwards.
    • Pan: Using the mouse left click.
    • Zoom in quickly on a specific point in the image: point with the mouse the point and press the Alt key. When the key is released, the view returns to the last zoom level.
    • Zoom out to preview the zero zoom level: Press the Shift key. When the key is released, the view returns to the last zoom level.

The Quality Report indicates after Initial Processing if it is needed to mark the Manual Tie Point in more images.

8. Repeat the above steps 2-7 to mark other Manual Tie Points.
9. Click OK.
