In blender it has become too much of a hassle to check the wireframe of the objects. You have to go to object properties > display and turn on wire and draw all edges.
As I was used to the wire frame on shaded in maya I thought It would be nice if we have a shortcut to directly enable and disable wireframe for all the objects in the scene.
Wrote this small script to do that... you can toggle wireframe display with shift + W
hope it helps.
