If you compiled your grammar with -debug, then it will wait on 
startup for a connection from ANTLRWorks before continuing.  When 
you're not using ANTLRWorks, you should regenerate your 
parser/lexer without -debug.

In this and similar rules, you might want to call the WS rule (or 
something like it) instead of coding the space 
directly.  Otherwise it won't match cases where the user has put 
tabs or newlines between the two halves of the keyword -- which 
would probably be unusual, but normally isn't illegal.
