Apparently that trace is just a marker around the perimeter of the mylar sheet, and does not perform any function other than decorative.

Before trying to bridge the broken trace, I plugged the keyboard back into the computer just to see how badly I had wrecked it by soaking it in soapy water (electronics and all) in my bathtub. To my absolute astonishment it is now 100% functional. The only problem that arose was a sticking "Alt" key, and a single drop of teflon lubricant fixed that. I now have two working AnyKeys, and three more coming in the mail. Is it possible to have too much of a good thing?

I guess these keyboards are pretty robust.
