 my main objective is to modify event queue elements within a DESK ACCESSORY
so that an application can retrieve modified keydown events.  somebody
suggested me to use NGetTrapAddress/NSetTrapAddress.  i looked up the Inside 
Mac but could not figure how to patch GetNextEvent using these two traps.
 then i posted a question on comp.sys.mac how to patch GetNextEvent and 
somebody suggested to use jGNEFilter saying that there was an article about it
in MacTutor.  that is my story.

 therefore, if i can modify keydown events within a desk acc without patching
GetNextEvent, i will be happy to hear the method.  if i have to patch, i 
would like to know how to patch it (probably using these two traps).

 thanks.
