Selection.IPAtEndOfLine Property (Word)
True if the insertion point is at the end of a line that wraps to the next line. Read-only Boolean.
A variable that represents a Selection object.
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.
If the insertion point isn't already at the end of the line, this example moves it there.
