When Fn-lock hotkey gets pressed to switch to function mode: [85951.591542] dell_wmi: Unknown key with type 0x0010 and code 0xe035 pressed [85951.591546] dell_wmi: Unknown key with type 0x0010 and code 0x0000 pressed When Fn-lock hotkey gets pressed to switch to multimedia mode: [85956.667686] dell_wmi: Unknown key with type 0x0010 and code 0xe035 pressed [85956.667690] dell_wmi: Unknown key with type 0x0010 and code 0x0001 pressed When radio hotkey gets pressed: [85974.430220] dell_wmi: Unknown key with type 0x0010 and code 0xe008 pressed These events are for notification purpose, so we can ignore them.
