OF is primarily the equivalent of the bios, and like any bios it knows
how to boot (but not how to _select_ an OS to boot). So far, I haven't
found any comprehensive list of keyboard shortcuts.

Last I heard, grub (v2) wasn't ready for ppc. I expect it's come on
since then, but at the moment you'll be using yaboot. I don't run OSX
so I don't know the exact specifics of disk-partitioning for it, but
it's documented on the yaboot site (look for it at www.penguinppc.org, I
think).
