    Alt-E

    If vertices are selected while doing an extrude, but they do not form an edge or face, they will extrude as expected, forming a edge. Similarly, if edges are selected that do not form a face, they will extrude to form a face.

    To force a vertex or edge selection to extrude as a vertex or edge, respectively, use Alt-E to access the Extrude Edges Only and Vertices Only.
