Zoom Tool¶

The Zoom tool allows the user to zoom towards or away from the map.

The Zoom tool provides the following options:

• If the left mouse button is clicked then the zoom is towards the map. The point clicked is the new center of the display after the zoom.
• If the right mouse button is clicked then the zoom is away from the map. The point clicked is the new center of the display after the zoom.
• If the left mouse button is dragged to form a box then the box indicates the new area that will be displayed on the screen (a zoom in).
• If the right mouse button is dragged to form a box then the area on the screen during the drag will be fit into the box (a zoom out).
• Rotating the mouse wheel will zoom towards or away from the map, keeping the center of the display the same.

An alternative to using the mouse wheel is holding alt- and moving the mouse left or right.
