Now that's a clever idea, never thought of that.

  The pin-out on every PCB is different. I've even seen two apparently identical keyboards have completely different pin-outs. But it's not very hard to figure out the mapping. Just open up a text editor and test out combining two different pins. Usually, there are three "long" pins on the ends of the PCB and about 30 short pins in the middle. You combine a long and a short pin to make a key code. This is where N-key rollover problems come from, so if you want your controller to support multiple button presses, you'll have to be creative in your selection, which means you will only be able to use it in apps where you have arbitrary control over key bindings.
