Something worth noting: some machines have both left and right command
keys and/or option keys, not sure which machines.  Those keys send
different signals, and in some cases, only one set works for
command-option-o-f.  Also worth noting, the timing is critical on
PowerBooks.  IIRC you have to hit it right as the machine goes bong, not
before, not after it finishes.  Finally, at least on the G3 series (black
rounded case), it usually only works when it's from a power-on, not when
rebooting.  Not sure why.
