I have Solus installed on a MacBook Air (2008). The keyboard lacks PgUp, PgDn,Home, End, and Delete keys, so I want to assign the commands for those to KbdBrightnessUp, KbdBrightnessDown, alt+KbdBrightnessUp, alt+KbdBrightnessDown, and Eject, respectively.
What are the commands and how can I do this?
