'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)
