You are right that you don't see them that often in SignWriting. They are generally used for more information (like for Spelling Sequence). I don't blame you for wanting to know where to find information about them. SymbolBank has a short eplaination about every base symbol of the IMWA. There I found this page:

I also go into SignText or SignMaker to see all of the symbols and how they rotate and what not. If you still don't understand something, please ask. :-)
