Quick camera question

I read about this in a tutorial somewhere, and for the life of me cannot find it again. Somehow my camera is no longer the default camera, and I cannot render with that camera view. How do I make my camera the rendering view camera again?

hit ctrl 0, and if it doesn’t change make sure that the little ‘lock’ icon is not pressed.

Aha. the lock button was pressed XD

Thanks, that did it.
