Question: Demo Camera Controls

I've noticed that under the "Camera Controls" options in the demo, the left/right arrow keys are supposed to rotate the camera. However, in the tutorial battle, they teach you that the left/right arrow keys pan the camera left and right, while you must push the mouse cursor to one side of the screen to rotate the camera. This seemed like an odd contradiction.

I continued playing the tutorial battle, and soon the Gauls were routed. Suddenly, I noticed that the left/right arrow keys were actually rotating the camera, rather than panning it. I thought this was great, until I selected one of my units, at which point the camera controls were set back to what they had been before, which meant that the left/right arrows were back to panning the camera.

Does anyone have any idea what might be going on? I prefer to be able to rotate the camera using the keyboard, since this leave my mouse free to be elsewhere. I'd rather be able to control the camera with only the keyboard, rather than a combination of keyboard/mouse.

What is your camera setting. During a battle if you hit escape and open on of the options(gameplay or video, can't rememer) you can set the camera to 'RTS' 'FPS' or 'Total War' on Total War the camera works just like in MTW where you can use only the keyboard
