JGNESample This snippet is a sample GetNextEvent filter which uses the JGNEFilter mechanism described in Tech Note #85 "GetNextEvent: Blinking Apple Menu". The init, written in MPW assembler, installs a filter which SysBeeps whenever a key is pressed with the shift key held down. The jGNE mechanism is the only valid place where the event record can be examined after a GetNextEvent call, since tail patching GetNextEvent breaks several aspects of the system.
