## Section1.1Rotating the 3D Plot & Key Shortcuts

Click on the 3D plot window and drag the mouse on the plot. This should rotate the surface in the direction you move the mouse about the focus point (the origin, by default). To reset the viewpoint to the original one, press the Home key (fn-left arrow on Mac).

Useful key shortcuts are shown below for rotating the plot and many other features (on any device with a real keyboard).
