Descriptions of symbols in the class view of a .NET solution

Where can I find descriptions of the various symbols used in the class view of a .NET solution?
Look for "Class View and Object Browser Icons" in the Microsoft Integrated documentation in Visual Studio. The URL is ms-help://MS.VSCC.2003/MS.MSDNQTR.2004OCT.1033/vsintro7/html/vxgrfclassviewicons.htm
