And furthermore, manipulating the active document from your NSApp delegate is often not what you want. For things like menu items that should apply to the active document, you'll want to connect to the First Responder instead. As an aside, if you do check the main window or ask NSDocumentController for the current document, be aware that neither one will work if your application is not frontmost at the time that the code runs. For reasons I don't fully understand, -mainWindow returns nil when the application is in the background, which shoots this down. Obviously not a problem if you're responding to a GUI event, but something to be aware of.
