global search

Is there such a thing as global search (and replace) in Scrivener? At least in the Windows 2.1 beta, there doesn’t seem to be. Is there a trick to getting S to search across files?

What is the purpose of the Option (in the Navigation tab), “Open all documents in editor view in search results list”? What is the search results list? Is this a Mac-only feature?
