### Zoom

Zooming is usually accomplished by holding down the left mouse button and dragging the mouse to delineate a zoom region. Some platforms may require using a different mouse button. The original plot can be restored by typing the 'u' hotkey in the plot window. The hotkeys 'p' and 'n' step back and forth through a history of zoom operations.

The option zoomcoordinates determines if the coordinates of the zoom box are drawn at the edges while zooming. This is on by default.

If the option zoomjump is on, the mouse pointer will be automatically offset a small distance after starting a zoom region with button 3. This can be useful to avoid a tiny (or even empty) zoom region. zoomjump is off by default.
