This year's event was no different.

United Keys Inc. unveiled the 205 Pro, a PC keyboard with small LCD displays embedded in the tops of each function key.

The LCDs use an "image converter" to display any changes to the keyboard's function keys. The point being the graphics become a reminder to forgetful users of what function can be accessed by each key.

United Keyboard CEO Ronald Brown pointed out that Microsoft alone has 950 different keyboard macros.

The image converter makes its changes by converting any image to hexadecimal code. Images can also be dragged and dropped into place.
