How do I make the camera look at things?

I have been looking around for the method on youtube, the forums, and here but cannot seem to find it. I am sure that it is fairly simple.

I want to trigger an event on a widget that makes the camera look at a certain actor while doing its matinee sequence.

“Find Look at Rotation”
feed it the cameras current location, and the location of the object to look at, feed the result into the cameras rotation

Sounds great. How can I access the cameras rotation?

first get the first person camera, then drag off the pin and set rotation
