I recently moved to Brazil from the US, and I am loving it. Since then I have tried to install a local keyboard in addition to the G15 keyboard that I own. Both keyboards are functional but both are using the the US layout and none of the "special" characters respond correctly. It is obvious that the Brazillian keyboard has the same layout as the G15. So here is my question, is it possible to assign differently layouts to two seperate keyboards (both which are usb) so that I can switch to the local Brazillian keyboard for my non english speaking friends? And if it is possible can you explain how. Molinski
