Example
This example sets the horizontal and vertical offsets for the
shadow of shape three on myDocument. The shadow is offset 5 points
to the right of the shape and 3 points above it. If the shape doesn't already
have a shadow, this example adds one to it.
Set myDocument = Worksheets(1)
With myDocument.Shapes(3).Shadow
.Visible = True
.OffsetX = 5
.OffsetY = -3
End With
