IPAtEndOfLine Property
True if the insertion point is at the end of a line that wraps to the next line. False if the selection isn't collapsed, if the insertion point isn't at the end of a line, or if the insertion point is positioned before a paragraph mark. Read-only Boolean.
Example
If the insertion point isn't already at the end of the line, this example moves it there.
Selection.Collapse Direction:=wdCollapseEnd
If Selection.IPAtEndOfLine = False Then
Selection.EndKey Unit:=wdLine, Extend:=wdMove
End If
