#### Plane Navigation

The navigation actions for this window are:

Left drag
  Pan. On the body of the plot this moves it around up/down/left/right. To move it only vertically, drag on the left of the Y axis. To move it only horizontally, drag below the X axis. You can configure dragging on the body of the plot to be only vertical or horizontal by setting the Pan/Zoom Axes in the Navigation axis configuration tab.
Right drag (CTRL-drag)
  Stretch zoom. On the body of the plot, dragging up/down stretches/squashes the plot vertically, and dragging left/right stretches/squashes it horizontally. Zooming is around the mouse position at the start of the drag. To zoom only vertically, drag on the left of the Y axis. To zoom only horizontally, drag below the X axis.
Center drag (SHIFT-drag)
  Frame zoom. On the body of the plot, dragging right-and-down or right-and-up drags out a frame; when the button is released, the plot will be zoomed in to cover the area enclosed by the frame. Dragging left (and up or down) does something like the opposite, you can zoom out using a similar (though not quite the same) mechanism. To zoom in/out only horizontally, drag right/left below the X axis. To zoom in/out only vertically, drag up/down on the left of the Y axis.
Wheel
  Isotropic zoom. Spinning the mouse wheel forwards/backwards will zoom in/out around the mouse position, just like dragging with the right button up-and-right or down-and-left.
