Command r not working

Hi, I'm trying to create a fusion drive but I need to boot into safe mode to access Terminal. I know holding command + r during start up is suppose to get me there but it's not working. I'm running 10.9 and I've tried using my regular Apple BT keyboard as well as a USB windows keyboard (tried windows key +r as well as cnrt+r) but I can't get it work.



Any suggestions??
