Where is macbook's keyboard backlight access binary prg?

[Sindhu S <sindhus live in>]

Hello

Sorry for the lack of clear title.

I am putting together my system in arch linux and am running /usr/lib/gnome-settings-daemon/gnome-settings-daemon binary in my awesome-wm session.

I looked through /usr/lib/gnome-settings-daemon... to set screen brightness there is gsd-backlight-helper but how does one access the keyboard backlight via the gnome settings daemon?

Thanks!
