auto-enable already works that way. If you attach to NSFirst it goes 
down the responder chain.

It works but it is not "enough".

If I want to enable "copy" only if an object is selected I need to ask 
my document or view if it has something selected inside. If you just 
validate if your controller supports copy there still might be nothing 
to do.
I wanted to go more "finegrained", up to the point where certain menus 
are enabled only if certain things are selected.
