<p>Described herein is an improved apparatus and method for aiding computer applications in processing information on a display via keyboard entries. The invention traps keyboard interrupt signals and determines, based on a particular interrupt signal, which key was pressed. If the key was one of the arrow keys, the PgUp or PgDn key, then, depending on which of a plurality of modes the system is currently in, an appropriate action will be taken. Actions include rotation of the current object on the display, movement of an object, zooming in or zooming out. Thus, instead of making the user wade through a plurality of menus and cursor pointings, pressing a single key accomplishes any one of a set of functions. <IMAGE></p> |
