If you want to find the FullName of a particular notation, one method is 
to wrap an example of the notation in Hold and look at its FullForm:

In[227]:= Hold[a::b] // FullForm
Out[227]//FullForm= Hold[MessageName[a,"b"]]

We discover that the FullForm version of :: is MessageName, which you 
can then look up in the help.
