After enabling the bigbrother code, hold [Ctrl] + [Shift] and press J to 
cycle through the different camera modes. 

These are: 

Mode 1: Controls the "X", "Y", and "Z" axis
Mode 2: Controls only the "X" and "Y" axis 
Mode 3: Normal 

To control the axis, you can use either the cursor keys, or the Left Mouse 
Button + Mouse Wheel. If you go through all three modes then hold [Ctrl] + 
[Shift] and press J again, you will start back at Mode 1, but without the 
values that you previously set.
