Multiple Cameras

I have two cameras, as i have one in a specifyed position i don’t want to change and the other i created so i could render a certain part of my landscape and see it in detail. When i go to camera view, my first, original, camera is what i see through and render through.

How can i change what camera i am looking through and/or is it possible?

A timely responce would be appriciated.

Select the other camera and press Ctrl+numpad0.

Can this be done through animation too? Or do you ‘have’ to use Python for that?
