I dont have time to look itup but there is some kind of key thing that lets you place keys on a mat anywhwere you want you could put a trackball (normal kind) in the middle I think and have those movable keys around the edges. Or your nordstrom can be surrounded by more keys. Or umm does the belken or siatech pads have more keys then the nordstrom?

Otherwise get a mouse with more keys some company makes a 14 button mouse or something google stainless and mouse and world of warcraft.
