Actually no, that's not how it works :)  The difference is even 
simpler: lexer rules start with a capital letter and parser rules 
start with a lowercase letter.

That one tripped me up for quite a while when I first started 
using ANTLR3, since I couldn't find anywhere on the website that 
mentioned the distinction.  (I haven't read the PDF, but it didn't 
exist at that point anyway.)
