When performing a select by location, sometimes it is necessary to select by location within the extent of another feature. For example, suppose you have a selection of point buildings that you would like to search through, to find the ones that are "within the extent of" areal building footprints. The points were placed very close to the centroid of the building geometry but are not necessarily within the areal buildings geometry. In this situation, it is not possible to use a buffer (since the neighboring buildings point may be closer than the actual point of interest). In either case, adding two options to the "That" portion of the "Select by Location" dialog that say; "are within the extent" or "are within the hull" would be useful.
