The Optical Allusions AHT (Advanced Hypertext) Help System is a revolutionary hypertext system of help.  This system uses both text and pictures with text, picture, and task links, supplying you with the most powerful help system ever.  This help system works much like the World Wide Web.  When you see one of the below links (which are color coded) you can click on the text to jump to different sections.  Pictures can also jump you to different sections.  A picture is a link if the arrow changes to a      when you position it over the picture.
   Tasks are a new idea (which will be found in System 8) that makes help systems even more powerful.  When you click on a link to a task, this help system will perform actions in MacMod Pro.
