Kiosk keyboard keys

Watershed’s internet kiosks have 5 special keys at the bottom: www. | .com | | :-( | :-). In earlier versions of the keyboards, these keys were actually just F1-F5 (which the computer then had to map to the right text), but it seems the later keyboards are programmed to tell the computer that […]
