If the parent window is a browser window, I believe what you want is 

NativeWebKeyboardEvent wrappedEvent(event)
if ([BrowserWindowUtils shouldHandleKeyboardEvent:wrappedEvent])
    [BrowserWindowUtils handleKeyboardEvent:event inWindow:[self parentWindow]];

This allows you to handle menu shortcuts, as well.
