The Kinesis Advantage Dual Foot Switch Accessory is the most efficient way to utlilize the unique foot input options provided with all Kinesis Contoured keyboards. The default actions are "Keypad Shift" and "Shift". The "Keypad Shift" action turns on the embedded keypad layer as long as the pedal is held down. If the Keypad Toggle function key is tapped first, then the "Keypad Shift" pedal will turn OFF the embedded keypad layer while the pedal is held down. With a programmable Contoured keyboard, the foot switch may be configured to perform any user-defined keystroke or macro!
