Comment 2 for bug 34897

Fn-Home/Fn-End. Aswell as generating nvram events on the ThinkPad these also get handled directly by the hardware.

The long-term solution is to map all the hot-keys through the input layer. Take the key-event, examine the appropriate hardware-state and if nothing has changed then process the action in software. Wifi/BT toggle, VGA/TFT and Volume are other examples of events that may or may not be handled at a lower-level, but which still generate the key-action.
