I am going to reply to my own post.  Are these correct:
Colors:
   Green = Public Scope
   Blue = Protected Scope
   Red = Private Scope
   yellow = enum value??
Symbols under the Symbols page
   () = Functions
   + = Constructor
   - = Destructor
   (Tri-block icon) = class or structure
   enum = enumurator
   Unions are listed under Others as the individual variable names
   {} = namespaces
