The keyboard subset contains one or more input buttons that can be customized to send keystrokes, hotkey sequences, or specialized commands to the computer. This device may be docked in the main keyboard for use during regular typing, or it may be detached and used separately from the main keyboard. (See Figure)

One advantage of this invention is realized when controlling a slideshow presentation from a computer or laptop. By mapping the detachable keys to the "Next Slide" and "Previous Slide" functions, the lightweight device can be separated and carried by the presenter. This gives the presenter complete control over the slideshow without needing to walk back and forth to the keyboard.
