                           The By Vertex option is available in all but the Vertex subobject mode. It requires that you click a vertex in
                           order to select an Edge, Face, Polygon, or Element. It selects all edges and faces that are connected to a ver-
                           tex when the vertex is selected. This is handy because selecting a vertex is often easier than selecting numer-
                           ous faces or edges.

                           The Ignore Backfacing option selects only those subobjects with normals pointing toward the current view-
                           port. This option is helpful if many subobjects are on top of one another in the viewport. For example, if a
                           sphere object were converted into an Editable Patch, you could enable the Ignore Backfacing option, and
                           then selecting subobjects on the front of the sphere would not select the subobjects on the back of the
                           sphere at the same time.
                           The Shrink and Grow buttons decrease or increase the selected subobjects by adding or deleting all adjacent
                           subobjects to the current selection. The Ring and Loop buttons are available only in Edge subobject mode.
                           Ring selects all edges that are parallel to the current edge, and Loop selects all other edges that have the
                           same alignment as the current edge.
                           The Select Open Edges option is active only in Edge subobject mode. This button lets you select all the
                           edges in the patch that are connected only to one face. This provides an easy way to quickly locate all the
                           holes in your current model.

                           At the bottom of the Selection rollout is some information on the current selection. This lists the current
                           subobject type and number selected.
