'underline' has nothing to do with looking up the command in
self.callbacks. It is a keyword parameter for the add_command method, and
is handled like all other values passed by name, and as you did for the
other arguments

         file_menu.add_command(
             label='New',
             underline=0,
             command=self.callbacks['file->new],
             accelerator='Ctrl+N'
         )

Note: PEP 8 style is no spaces around '=' used for keyword arguments. Here is an example from idlelib.editor, 978.

   menu.add_command(label=ulchars[i] + " " + file_name,
                    command=callback,
                    underline=0)

Thank you for the clarification.
