I wasn't exactly sure what forum to post this in.  Please advise if you think a different one would have been more appropriate.

I help people with Office products on a fairly regular basis.  I struggle sometimes with Office versions that I'm not familiar with.

Does anyone have a recommendation of a resource that shows the menu structures for different versions of Office? 

Ideally I would like to see a "simulator" where I could interact with the different versions live over the web but just having a group of screenshots of all the different menus / ribbons would be a nice start. 

Thanks!
