i just need one simple little question

hey how do you activate a freakin camera. for some reason i do this every once and a while and i deactivate a camera and then the rendering of coarse gets all screwy. how do i reactivate or select a different camera.

o and what ever happened to the chat room thing on elysiun? i miss that. i used it a lot for quick little questions like this.

Select camera and press Ctrl-0

thanx dude. i can do a lot on blender ive just never learned how to do that one little task.
