The magnified portion of the image is selected un,der control of a pointing device connected to the computer. A method is described for changing the characteristics of the magnified portion. A configuration utility which creates the magnified portion of the display includes a menu of display properties for the magnified portion. The properties are selected from the display menu, and each refresh of the area within the magnified portion of the image is refreshed with the selected properties. In a text/browser application, the background color, text color, text style and size may be selected differently than the remaining portion of the image displayed on the computer display.
