Open folder in <ugh> Explorer?

Once in a while I want to look at something in Explorer. But I guess I have full integration set. I tried launching folders on the Explorer command line, even that opens a Lister. How can I do this from a menu? Is it difficult?

Thanks

Perhaps with a button command something like:

"/windows\explorer.exe" /n, /e, {s}

That works great, thanks!
