1. A method of illuminating a computer keyboard, comprising: providing a computer keyboard that has keys that are each individually illuminatable; after a key on the computer keyboard has been pressed, probabilistically determining the most likely key or keys that would be pressed next; illuminating the key or keys that are determined to be probabilistically most likely pressed next while leaving the keys probabilistically least likely to be pressed next unilluminated, wherein an electronic dictionary is utilized to determine, for selective illumination of keyboard keys, the most likely keys to be needed and wherein the electronic dictionary presents suggested keys based on a specific application that is running on a computer such that, if a calculator application is running, numeric keys will be illuminated and if a word processor application is running the most likely alphabet keys, along with enter and space bar, will be illuminated; continuously updating the electronic dictionary to include new words typed on the keyboard; automatically disabling the selective illumination of keyboard keys when user identification and password fields are being filled; providing a user with the option of enabling or disabling the selective illumination of keyboard keys; after a configured timeframe when none of the suggested keys have been pressed, automatically illuminating all of the keys; after an additional configured timeframe where none of the illuminated all of the keys have been pressed, unilluminating all of the keys.
