Yes, sir!  When you click unlock, a screen comes up asking for your password/phrase, on the lower left hand corner there's a small checkbox that say's "unlock for staking only".  Click that box, put in your password/phrase, and then hit okay.  In a few seconds to a minute or so, on the lower right hand corner you'll get a green miner's hammer that says that you're staking and how much, etc.  It should say how long until you get your first block reward.  Getting your first block reward is amazing, lol!
