- (void)keyDown:(NSEvent *)event {
    consumedKeyDown = NO;
    [self interpretKeyEvents:[NSArray arrayWithObject:event]];
    if (!consumedKeyDown) [super keyDown:event];
}

- (void)doCommandBySelector:(SEL)selector {
    consumedKeyDown = [self tryToPerform:selector with:nil];
}

-- where consumedKeyDown is an ivar.

Cheers, and sorry for the miscommunication,

Hi, Jim,

NSResponder has -scrollPageUp: and -scrollPageDown: as two of its overridable methods. I don't believe that you will need -keyDown:.

Cheers,

I have a custom view which can be (and often is) embedded in an NSScrollView.

It appears that I get page up/down behavior for free. (By way of - [NSWindow _processKeyboardUIKey:].) But I don't get home/end behavior for free. (Is this a bug or oversight?)

What is the correct way to implement home/end?

I currently have overridden -keyDown: to call -interpretKeyEvents: and have (re)implemented the NSReponder methods for page up/down and home/end. This works, but is it the expected/correct design pattern?

Jim
