More broadly:

*  Do all the _non-alphabetical_ commands (or symbols, or operators, or 
abbreviations, or whatever is their proper appellation) like  "/.",  
"//.",  "->",  "=>",  "@",  etc, etc, etc, have a unique appellation _as 
a class_?

*  Does each of these non-alphabetical constructs also have a unique 
individual name?

*  Suppose one wanted to get a complete (complete!) list of all of these 
non-alphabetical constructs, their names, and maybe a brief description 
of their meaning, to use maybe as a reference list, a crib sheet, or 
just to see which of them one hasn't learned yet.  Where would one go?
