I was googling for a way to wrestle control of the keyboard's backlight away from the unhelpful control of the ambient light sensor, and I stumbled upon this developer page.

What most interested me was this:



so Fn- is Windows key and Fn-enter is Menu key. I always just assumed that was part of the windows emulation software, but it's actually hard coded on a much deeper level.
…I just thought that was pretty interesting.
