How to mod keyboard to use SPST switches? Answered

I'm converting my bluetooth keyboard into a foot controller for my iPad.
I opened it up today and I don't understand how the signal gets sent in a keyboard. It looks like the piece of rubber presses down to a white dot, and I don't get how that works.

How can I mod this to use momentary SPST switches to send signals as if they were keys on the keyboard?

The key board works on the same principle as a touch pad SPST switches will work but you may need a resistor in line with the switch.
