Select Features
The Select Features tool selects features from GIS layers when ArcObjects has been enabled (the Select Shapes tool is used when ArcObjects is not enabled). All features from selectable layers will be selected as long as the layer is visible. A layer can be turned off from the Project Explorer so that it is not visible, and therefore not selectable. The layers can also be made un-selectable by using the Selectable Layers... command in the Selection menu. The following dialog allows users to check or uncheck layers as being selectable.
Individual features can be selected to create a new selection, added to the current selection, taken from the current selection, or selected from within features already selected as specified by the Interactive Selection method defined from the Selection menu (by default the selection method is create a new selection).
Multiple features may also be selected by dragging a box around all features that the user wants selected. In such cases all features that have any portion within the selection rectangle will be selected.

The Identify tool can be used to view the attributes of selected features (points, lines, or polygons in a GIS layer) in a GIS layer. When selecting a feature the attributes are displayed in the Identify Results window. By default, with ArcObjects enabled, only the attributes of the selected feature in the top most layer (as displayed in the WMS Project Explorer) are displayed, but the Layers drop down combo can be changed to All Layers, or a specific layer as shown in the figure below.
With ArcObjects not enabled, attributes of the selected feature in the top most layer (as displayed in the WMS Project Explorer) are displayed, while features from other shapefile layers can also be viewed by selecting them in the dialog as shown in the figure below.

The Select Shapes tool is used to interactively select shapes when ArcObjects is not enabled. Individual shapes may be selected using this tool and, when holding the SHIFT key down, newly selected shapes can be added to the selection list. A rectangle can also be dragged and all shapes that have any part within the rectangle will be added to the selection list.
