Adding and editing second camera

Hi.
For some reason I am unable to change the position or zoom of my camera. I am trying to add in a second camera for a cut to a closer view of a character in scene but when I add the second camera I am unable to do anything. The camera view bow that is usually red and movable is grey and it does not have a grab handle. I can move the position of the camera’s cone but the camera view does not change. Any help or insight is appreciated.

Well, if you like, here is a little “video-demonstration”:
