Go to start of timeline on MBP

update: why yes, it was a stupid question: I just found it under view: playback: play from beginning (control-shift-I).

Probably a dumb question, but what's the keyboard shortcut to go to the beginning of the timeline, on a Macbook Pro (I know you can hit the home key on a desktop Mac)? In the menu under Mark I see "go to beginning" with a diagonal arrow, but I don't have diagonal arrows or home keys on my 2009 MBP.
