You can also do it by adding a "delete:" action method to the document 
or window controller that is in charge of the table view's window, and 
have that action do whatever is necessary (in the simplest case, send 
a "remove:" action to the NSArrayController controlling the table view).

The catch is that you may need to look at the window's first responder 
to check that the delete came from the table view and not somewhere 
else in the window.

But it's fairly easy to add refinements like confirmation dialogs if 
you use this approach.
