For those of you not in the know, magnification software "does what it says on the tin". That is,it magnifies the details on the computer screen, typically from two times to 16 times. Most software packages will also allow you to magnify in different ways. For example, magnifying the whole screen as a whole, allow you to split the screen either horizontally or vertically, and some also allow you to use the mouse like a handheld magnified.
The market leaders are probably Magic (from Freedom Scientific), Lunar (from Dolphin) and ZoomText (from ai squared). I am familiar with all three of these products and will show you how to configure them to just the way that you want and how to get the most out of them for whatever programmes you use most.
