Selectable Layers Tab
The Selectable Layers tab displays the feature layers that may be selected in the map. If the checkbox next to a feature layer is checked, features in that layer may be selected on the map. Feature layers with unchecked checkboxes may not be selected in the map (e.g., Building, Map Grid, and Parcel in the example below). Check or uncheck a checkbox to modify its selectability. Hold down the Ctrl key while clicking a checkbox to select or unselect ALL checkboxes in the list.
