I would keep it off (>and leave it off) until whatever spilled dries thoroughly. It sounds like your rapid action might have saved it!
Anyone have thoughts/input on my situation?
In the future, keep the beverages a full arms length away from your computer.
Incidentally, I follow my own advice. My coffee is almost an arm's length away from my computer and on an extension which makes it virtually impossible for an accidental spill to run into my KB.
I think you're ok because of your quick action. Most of the occurrences I've read the liquid shorted out components immediately. Let yours dry thoroughly before turning on again.
