CHUWI tablet Windows Button Trapping?

The CHUWI tablet (dual OS) running android has a "physical" (sort of) windows icon button below the screen that works like a back button. But trapping keypresses does nothing so it must not be a keypress that B4A sees. The question: Can I trap for that button and return true so to block it's function as aborting my application?
