I like taking screen shots from films I have and using them for training material but there is only are only X, Y, and Z axis keys for the camera position using the keypad, arrow keys, and page up and page down. I'd like to see a roll camera key so, for instance, I can roll the camera level with the horizon and make the screen shots I use for training purposes a little less confusing.
If this function already exists then I apologize for wasting your time and please tell me the key for it!
