In a collection that uses multiple selection, the navigation keys move the location cursor independently from the current selection. The Select key or the Spacebar on an unselected element adds the element to the current selection. Pressing the Select key or the Spacebar on a selected element removes the element from the current selection. 

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