In a collection that uses single selection, the navigation keys move the location cursor independently from the selected element. If the user presses the Select key or the Spacebar on an unselected element, the element with the location cursor is selected, and any other selection in the collection is deselected.  

Single selection supports only add mode. Pressing the Select key or the Spacebar is similar to clicking BSelect.
