rewiring keyboard matrix?

I want to know if it is possible to rewire the traces that go to the numpad on a keyboard so that the numpad section can be cut out? I've seen some boards where this is done but no explanation was given of what's going on. The trace that is supposed to go to the numpad keys should be rerouted back somehow, I am guessing.

You'll need to pull it apart and map out the traces. If there is a continue loo on one of the sides that goes through the number pad area then you'll need to add a new trace to reconnect that loop once the number pad is cut out.
