Here are some screens shots of KDE using right click on mouse and the cjk keyboard. The mouse does not show in screen shots but the pointer is the size of a pc mouse pointer. On screen very fast and right clicking, left/right mouse and scroll wheel all work. Thanks to Penguinbait on KDE, and Jolouis and Benson on otg adapter and mouse and the guys who did the work on the cjk keyboard for all their hard work. Dan
