iTunes hotkeys

I've tried searching for this, but I guess I'm using the wrong keywords.

When I'm in Firefox for example, and I want to change to the next song, is there a key combo I can hit to do this? As well as pause, etc.

Thanks!

You need to download a 3rd party app that can control iTunes, google for iTunes controller.

I've been using this free app and it works well: http://www.yousoftware.com/tunes

oh yeah, and QuickSilver has an iTunes plugin
