I haven't got around to adding any actions to text fields

In the meantime, you could put a key_down method on the
containing window that catches the Return or Enter key.

Unfortunately that's not easy to do at the moment. Due to
disparities in the way events are handled by the underlying
toolkits, PyGUI doesn't promise to let you intercept events
on the built-in control types by overriding methods.

I really need to rethink the whole event handling stragegy,
as it's rather a mess at the moment.

That's another thing for the future. If you're feeling
adventurous, you could have a go at rolling your own based
on a View.

Anyway, glad you're finding it useful. Feel free to ask if
you have any more questions.
