New REPL multiline editing feature not documented

Documentation

Reading the Python 3.13 release notes I became curious about the new REPL multiline editing feature:

However, I cannot find any explanation of this feature in the documentation. Clicking on the "interactive" link redirects to the Appendix which mentions the new interactive mode, but doesn't add anything about the multiline editing feature that isn't in the release notes already.

I suppose there's not that much to document other than that one can now navigate multiline commands with arrow keys, something that wasn't previously possible:

See also PEP 762 "REPL-acing the default REPL": https://peps.python.org/pep-0762/

A nice write up on the new REPL I found is: https://realpython.com/python313-repl/

Hi! Is this an open issue? If it is, could I help with this? I'm a newcomer and would like to contribute to CPython if possible.
