title: How do I enable the various menu items created by default in a cocoa application?
body: <p>I am trying to make a GUI for a simple hex editor that I have made. But I can't enable any of the default menu items (i.e. "Open...", "Save", etc) No matter what I do they are always grayed out and un clickable.</p>
  
  <p>I have tried to link the "Open..." menu item to the First Responder Object's received action <code>openDocument:</code> as well as making a new class name <code>FileMenuController.m</code> that only has one method <code>-(IBAction)openDocument:(id)sender;</code>  I am new to Xcode, Interface Builder, and Objective-C and at a loss for how to proceed.</p>
  
  <p>Note: This is not a document based application.</p>
  
  <p>Thanks for the help!</p>
