[Newbies] Is there a way to find examples of how a certain method is used?

[Murphy Stein]

Hi All,

I am trying to find some good examples of how the Dictionary class is  
used, particularly basic stuff like examples of how add: works.  The  
sender button in the SystemBrowser calls up about a million examples  
of add: , but I don't see a way to filter by a specific class.  Is  
there a built-in way to do this?

Thanks,
Murphy
