Select - Reselect reselects all points and objects that were unselected in the last unselection action. For example, if you have selected a group of objects and then unselect one object by use of a click of the mouse while pressing the control key, Reselect will once again add that object to those presently selected. This item is unavailable whenever the last action included a selection of an object or point.
