If you want to use f7 and f8, you need to turn on the thing above or instead, whenever you want to orb, you hold down that little key called "fn" and then press f7 and f8. (Holding fn turns off the special functions for those keys) Personally, I just rebound the admin controls to M to orb and N to drop player.
Thanks, I totally understood it now. Everybody were telling me different things.
