I now know what S31 is. (F2)

On the circuit board there are a bunch of connectors. 1 connector only has 2 wires in it. This connector does switches 25 - 32 per the silk screen on the board. Hmm.... I wonder. The sitches are active low, meaning you ground the contact to activate. So 25 & 26 are used. That leaves 27 - 32. Grounding these comes up with (including 25 & 26 for reference)

25 - X
26 - [
27 - ESC
28 - ENTER
29 - TAB
30 - F1
31 - F2
32 - P

So all you have to do is add a switch to these lines on the connector with one side of the switch going to ground.
