Hi Dmitry thanks for the reply. see [1], I change the [Red arrow] key to [ALTGR] then I can easy change the defkeymap.map. make all the red keys work. but for the [Blue Fn] key. I don't know how to make it work in keymap? there is [SHIFT] [CONTROL] [SHIFT] [ALTGR] four modifier keys. all used. so I can not may the [Fn] to those four modifier keys. can I make the leftAlt and rightAlt generate different keys? like: LeftAlt + 'U' = Alt + 'U' RightAlt + 'U' = '7' thanks for help.
