MAGic will magnify your screen in several ways, depending on how you set up the controls palette. Also, MAGic will read what it magnifies, including words you type.
When you select MAGic from the desktop, the control pallette is superimposed over any application you have open. Toggle any of the controls on or off, and right-click to fine-tune its settings. After you set up the magnification you want, you can minimize the controls.
