Hey!  You found the sample input port and the sample button!  Just
kidding...  =)

Heh, you have one of the early boards that still has the debugging
connectors on it.  I think the first large batch of these inadvertently
came with that connector still stuffed.  Later rev boards just have an
empty space for it.  That connector allows you to program the PIC
(handles button scanning, LED lighting and the keypad scanner).  It's
the chip in the upper right of your picture.

Another vestige of the early rev boards.  When the board was laid out,
somehow an extra button creeped in.  It doesn't do anything.  Again,
later revs still have the circuit, but the switch is left unstuffed. 
Wait, maybe I'm wrong.  What I was thinking of is an extra LED that
snuck in under the 7seg EDIT button.  I'm not sure what that switch is.
 Maybe a reset for the PIC, but I doubt it since it's way over there. 
Hmm, now I'm curious...
