Selection.MoveStartWhile (Word)
Moves the start position of the specified selection while any of the specified characters are found in the document.
While any character in Cset is found, the start position of the selection is moved. This method returns the number of characters that the start position of the selection moved as a Long value. If not Cset characters are found, the selection isn't changed and the method returns 0 (zero). If the start position is moved forward to a position beyond the original end position, the end position is set to the new start position.
