Optional Object. The direction in which to collapse the selection.
Can be either of the following WdCollapseDirection constants: wdCollapseEnd or wdCollapseStart. The default value is wdCollapseStart.
If you use wdCollapseEnd to collapse a selection that refers to an entire paragraph, the selection is located after the ending paragraph mark (the beginning of the next paragraph). However, you can move the selection back one character by using the MoveEnd method after the selection is collapsed.
