You can also use the mouse wheel to amplify, de-amplify and scroll horizontally. In the case of a 2-plot, move the mouse inside the plot to amplify it (the projections remain the same) or over one of the projections to amplify it (the main plot and the other projection remain the same). On the Mac, you can temporarily disbale the option “Mighty Mouse Can Scroll” with a modifier key (like the ⇧ key).
When you drag something, you can optionally use the ⇧ key to restrict the movements.
When the scale coincides with the margin of the plot, the following rule determines what will move when you click: if you drag outside the plot, the scale will move; if you drag inside the plot, the margin will move.
