Abstract
An input device with a user-selectable key that includes a proximity detector associated with the key. The proximity detector detects the proximity or touch of a user's finger and provides user feedback related to the function of the key, without actually activating the function of the key. This allows a user to determine what a particular key on a keyboard or other device will do by simply hovering the user's finger near the top of the key, or lightly touching the key without depressing it.
