Ah, well if the bluetooth version of the keyboard actually uses a standard HUT code for that and that maps to KEY_FILE, then I agree that it would be best to map the "F-12" key to KEY_FILE. > Personally I've no fondness to what the keys map to, since I remap them to > how they are labelled on an Thinkpad X230, which is pause/nexttrack.

If you switch F-11 to KEY_SCALE in the next version of your patch set, then I'll send a followup patch for thinkpad-acpi to change F-12 to KEY_FILE, and then the 2 mappings will be in sync. Agreed ?
