Some ASUS laptops like UX550GE has hotkey (Fn+F7) for keyboard backlight toggle which would emit the scan code 0xc7 each keypress. On the UX550GE, the max keyboard brightness level is 3 so the toggle would not be simply on/off the led but need to be cyclic. Per ASUS spec, it should increment the brightness for each keypress, then toggle(off) the LED when it already reached the max level.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
