Each view represents a camera. The cameras are moveable and support many options. To move a camera, two techniques can be used. Even at the same time! The first technique involves the use of the space bar. Holding down the space bar (in any mode) puts the mouse into a special movement mode. In a 2D view pressing the left mouse button while holding the space bar will allow you to pan the camera rapidly. In a 3D mode, the left mouse button allows you to orient the camera. The right mouse button allows you to pan the camera. The mouse wheel works in either view as a method to zoom the camera in.
