Inside Mac, vol. I, p.254:  

"	There's also a global _system event mask_ that controls which events
get posted into the event queue.  Only event types corresponding to bits set
in the system event mask are posted; all others are ignored.  When the
system starts up, the system event mask is set to post all except key-up
event - that is, it's initialized to

	everyEvent - keyUpMask

Note:	Key-up events are meaningless for most applications...[You can] set
	the system event mask with... SetEventMask."
