Gary talked about selectors and some of the specific calls for  
manipulating menus and menuitems. I have some additional discussion  
and code examples for manipulating menus in the interface tutorial  
that is in .../ccl/contrib/krueger/InterfaceProjects/Documentation/ 
InterfaceBuilderWithCCLTutorial. If you're not already familiar with  
it, one of the things you'll need to understand to make your changes  
work is the First Responder chain which defines where selectors  
without a specific target are sent. That is discussed in the tutorial.  
If you prefer, it is relatively straightforward to alter the menu  
items so that they send a selector of your choice to a specific object  
of your choice, but then it would be up to you to figure out what  
window was on top (if any) and what document it was associated with so  
that you know what to act on.
