# Navigation Tools
**The magnifying glass** allows you to zoom in or out on a selected point of a surface. Left clicking will zoom in, right clicking will zoom out. Clicking and dragging the left mouse button will zoom in on an area of interest.
**The grab tool** allows you to move the surface on the screen by clicking and holding, then dragging. This is most useful with large surfaces or when zoomed into a single section of the surface.
**The pointer tool** switches the cursor back to selection mode.
**Zoom to full extent** will change the zoom level to fit the entire surface on the screen.
**The crosshairs** will toggle on and off the display of a crosshair at the mouse’s position on the working area.
**The camera** captures the surface as a geo-image with latitude and longitude or UTM (easting and northing), in multiple standard image types.
**Google Earth** will capture the current display area and overlay it on a satellite image of the field location.
NOTE: You must have Google Earth Pro installed on your computer for this to work.
**The ruler** is used to measure the distance along a selected origin point and the current cursor position. Left-click to add points, and right-click to start measuring a new line. The tool measures the total length of the line and the area enclosed by the line will also be displayed.
**Rotate** will cause the surface to rotate 90° to the right with each click. There is no option to change rotation direction or degrees it will rotate by.
