To them, ease of use was pretty much a hypocritical concept. A two-inch curb is enough to prevent a motorized wheelchair from getting up on the sidewalk. For that reason, we set ourselves the task of trying to identify where we needed to build, in effect electronic curb cuts into the computer. Suppose, for example, that you're working with a Macintosh and you make a mistake. Or consider the repeat key.
Most good typists report that it's a wonderful feature.
Most good typists, however, don't have poor gross or fine motor skills. If they did, they'd discover the frustration that's caused by not being able to remove their fingers from the keys quickly enough and, as a result, end up with rows of repeating characters filling up the screen. There are also other obstacles, generally born of an attempt to improve hardware or software technology. For example, most software programs now and again require you to press down two or three keys simultaneously. This is impossible if you happen to be able to type only by using a head wand or mouth stick, or if you are able to use only one finger.
