From ca51c1ad22ab812ee2611f5a22c93688ffd9b5f3 Mon Sep 17 00:00:00 2001

Subject: [PATCH 04/11] HID: asus: add keycodes for 0x6a, 0x4b, and 0xc7
These two keys are found on some models with dual display.
- 0x6a is intended for controlling the secondary screen brightness.
- 0x4b is intended for toggling the arrow keys between arrows and
page up / page down.
This key is found on a slightly modified keyboard layout.
- 0xc7 is intended to cycle through keybvoard brightnesses (upwards) but
there is not suitable existing code for this behaviour. Using
`KEY_KBDILLUMTOGGLE` is different behaviour to Windows but at least
is picked up by many desktops already.
