"Home" and "End" keys in FCP on MacBook Pro (2008/09)

I just started using my new MacBook Pro 17. While I was in FCP and tried to move the playhead to the "Home" position, I realized that my keyboard doesn't have a "Home" or an "End" key. What keys/functions do I need to use in this case? When I tried to look up the solution online, I found a forum in which someone suggested "Command/Arrow Key" (up for "Home" and "down for "End") but that didn't work.
Thank you!
