Keyboard and Volume?


I know this is a little off subject with OSX but doesnt anyone know how I can set my f1 - f12 keys to adjust my volume in OS 9.0.4? I know some people are able to but I can't figure it out. if anyone can help me out thanks.
Speaking of F-keys ... How about a way to program the F-keys to open files and apps the way you can in OS 9? (And before OS 9, I used a 3rd-party utility called QuickPop to do the same.)
