All layers in a map are listed to the left of the map in the legend. The legend shows the layer name and the symbol used to draw each layer. The check box next to each layer indicates whether it is currently turned on or off in the map, that is, whether it is currently drawn on the map or not.

The order in which the layers are listed in the legend is also important. The layers at the top of the legend are drawn on top of those below it. Layers that form the background of your map are listed at the bottom of the legend. To change the order a layer is drawn in, drag the layer up or down in the legend. The Move Layer choice on a layer's right-click menu gives options for moving the layer.

You can change the width of the legend by dragging the border between the legend and the map either left or right. This is useful if you want to increase the width of the legend so that you can see long layer names.

You can turn the legend off by clicking the View menu and unchecking the Legend choice.  You must Refresh Map to view your changes.
