Moisture damage?

As I'm carrying my MacBook Pro down the street, the skies opened up and I got caught in a downpour. Not thinking anything of it, I did not power down and now the "enter/return key", the "right side shift key", and the "page up/down/and sideways" keys have all stopped functioning. Do I have any recourse or should I start playing "Taps"?

Have a read through this - http://www.mac-forums.com/forums/apple-notebooks/219598-official-i-spilled-liquid-my-macbook-what-do-i-do-now-thread.html - you may get lucky but water never plays well with the MacBooks. I'd at least make sure it was powered down and open it up and dry everything off really well - and then see where you're at.
