global wire-frame

Is there a way in blender 2.5 to do a global show wire-frame. For example if you select an object and under display you have an option to toggle "wire. This however is for the selected object only. Is there a way to do a global wire for all objects in the scene. Akin to the f4 key in 3ds max for those who are familiar with Max.

In the menu header for the 3d window, to the right of the mode selection box is your display options. Z-key also toggles to wireframe. If you want wireframe overlayed on top of colored mesh, the only way I know to do that is thru the object panel display options on a mesh by mesh basis.

Hope this helps,

Yeah, I was looking for global toggle for a wireframe over the open-gl mesh. thanks for the info anyway, appreciate it.
