PowerBookG4 F keys

ok here's the deal.. for example when using Macromedia FlashMX if u press F9 the actions box should open but with the powerbook if i press F9 it lowers the keyboard light.. what can i do so that when i press F9 for example it opens the actions box.. Also if i wanted to say burn a music cd or a data or something like that.. what software should i use??

PS: i'm new to mac plattaform and i appreciate whatever help u guys give me.. thanks

First question I think if you hold the Alt/Option button it allows you to use the F buttons (I forget since I haven't use a PB in a while)

Second question...Finder for Data, iTunes for Audio. if you want to get another program the best is Roxio's Toast

its alt...

Actually its the "fn," button, usually in the lower left of the keyboard.
