GarageBand 10 "Go to Beginning" keyboard shortcut missing?

What is the keyboard shortcut in GarageBand for "Go to Beginning" now that "z" is no longer an option? Or is there no alternative? A single letter cannot be added in System Prefs, Keyboard Shortcuts (I prefer this to using two keys since i use it so much). I've hit every key and it's just not there - though I do not have a numeric keypad, which some beefier DAWs rely on. Thanks!
