	That was an encouraging article at least as far as it
goes. I've been in computers now for 30 years this month and
great strides in accessibility have always just been around the
next corner or so. Having never used a touch-screen device, I
have one question.

	What is the difference between moving the point of focus
around the screen and actually making the choice? If the device
gave out audible as well as visual prompts as one moved a finger
over the screen, it would be possible to tell what you were
about to select. What sort of action does one do to tell the
device that this is what I want as opposed to just touching the
screen. In mouse terms, it's the difference between moving the
mouse and clicking on something.
