Question

The new release of IPython does not depend any more on readline but uses the pure Python library prompt-toolkit, solving maintenance problems on Apple\

Answer 1

You could change xterm's configuration.

xterm is configurable (and documented). In the xterm manual, the Default Key Bindings section shows the default binding for this key:

                        Alt Return:fullscreen() \n\

You can suppress that binding in more than one way:

• using the omitTranslation resource to suppress the feature
• setting the fullscreen resource to never

However, just suppressing it will not make it send something interesting (xterm ignores the modifier for Enter). Setting a translation resource works, e.g., in your $HOME/.Xdefaults file:

*VT100*translations:      #override \n\ 
     Alt Return: string("\033[27;3;13~")
