setTimeout in Flash MX2004?

Hello,
I’ve been searching this forum for a way to have animations appear at different times from each other. A lot of threads advise to use setTimeout, but I don’t think my version of flash even has this capability. When I type the word ‘setTimeout’ into my actions frame, it doesn’t turn blue like it’s a recognized function in flash (like if I were to type the word ‘function’). Can somebody please explain this for me?
