You move around a lot more and faster than I do on a touchpad!

I don't think I've ever manually changed the backlight level on any of
my various laptops. My wife's netbook automatically dims. I found that
annoying initially, but it brightens back up when you do something with
it, so it's really minor.
Possible that those Fn+key combinations are activated by the laptop's
ACPI BIOS (or equivalent). I doubt many BIOSes are RT safe!
