|  | Above and below the  illuminated page on the left - 
      framed in black - you will find buttons which enable you to magnify (Zoom 
      in) and to reduce (Zoom out) the picture. If you move the mouse over one 
      of the four smaller buttons in the middle the picture will be moved upwards, 
      downwards, to the left or right. The Internet Explorer does not support 
      the function of the Zoom buttons. Alternativ you may open the context menue 
      by clicking the right mouse button (Win 9x/NT) or by clicking the mouse 
      button during pressing "control" (MacOS) and then click on "Zoom 
      in" and "Zoom out". You can move the enlarged page by hand 
      by pressing the mouse button over the page. If there are instructions for 
      the illuminated page in the Model Book a small icon can be found on the 
      right. Clicking on the icon shows the corresponding pattern from the Model 
      Book. |
