Query: Depicting a generalized shift move in crown diagrams   This paper gives a diagrammatic way to perform a generalized shift move on a
crown diagram of a smooth 4-manifold. Applications include a simplified proof
that if two crown diagrams are related by a generalized shift move, then they
are slide-equivalent; a method for converting a genus g > 1 Lefschetz fibration
into a crown diagram; and the fact that the vanishing cycles of such a crown
diagram are slide-equivalent to a standard inclusion of the Lefschetz vanishing
cycles into a genus g + 1 surface.
