Please, I never got a answer to this. In Xcode 3, you could go to the help tab; click on open man page; type in what you were looking for (i.e. memcpy); and the men page would open. How do I do that in Xcode 4? BTW. I complained that Xcode 4 didn't have an open recent file choice. It does, however, allow the creation of workspaces without the need to start a project.
