I haven't used this in a while, but in my keyboard shortcut settings 
(Settings -> Keyboard -> Application Shortcuts) I have a couple of keys 
mapped to "light -A 10" and "light -U 10".  (Note:  requires the "light" 
app to be installed.  https://github.com/haikarainen/light  That app 
apparently has been orphaned, but I'm sure there's something similar 
available.)

HTH,
