A system and method of using object sensitivity values and a cursor to select a graphical object from a plurality of graphical objects and sub-objects appearing on a display device. The plurality of graphical objects includes at least one container. A sensitivity value from the set of Normal, Opaque, Transparent, Invisible, Customized, and Automatic is designated for each of the objects. At authoring time, a sensitivity value from this set can be easily assigned to each of the objects, thus affecting the way hit testing proceeds over the objects. More particularly, an object is selected from the plurality of objects based on the position of the cursor, object position, object containment, and the sensitivity value of at least one of the objects.
