Allow Edit Boxes to Use Leading Space
This only applies if the External Leading option (above) is non-zero. If so, it allows edit boxes to extend approximately half way into the leading area below the current row. This is often useful to allow sufficient space for the characters to fit within the box. (Depending on your scaling options, window size, etc., you may find that your edit boxes are clipping off the bottoms of the characters. If so, this is one way to deal with it.)
