However, I've found that when an NSTextView receives a keyDown
event that doesn't handle, it doesn't bother to send the event down
the responder chain and just calls NSBeep().
I expect that there isn't a keyDown event that NSTextView doesn't
handle. It sends them all to -interpretKeyEvents. The events go
through the system input manager and get back to the NSTextView in
the form of -insertText: or -doCommandBySelector:. It is
doCommandBySelector: that is firing the beep. You can set a
breakpoint on NSBeep to see the call stack.

You were spot on, Ross. Thanks for the help. Instead of keyDown: being
passed down the responder chain it is doCommandBySelector:.
The solution I've used is to override doCommandBySelector: and convert
it back into a keyDown: call in the last responder in the chain.
Here's the code:
- (void)doCommandBySelector:(SEL)aSelector
{
NSEvent* e = [NSApp currentEvent];
if([e type] == NSKeyDown){
[self keyDown:e];
} else {
[super doCommandBySelector:aSelector];
}
}
Kind regards,
Tom
