Hi @aoxiangcao, this [example](https://github.com/jupyterlab/jupyterlab/tree/master/examples/notebook) is still the best place to start.

@afshin, Up/down at the edge of a codemirror: https://github.com/jupyter/notebook/blob/master/notebook/static/notebook/js/cell.js#L234

It looks like the current notebook is still using the deprecated `payload` shell response for the pager: https://github.com/jupyter/notebook/blob/master/notebook/static/notebook/js/codecell.js#L347 http://jupyter-client.readthedocs.org/en/latest/messaging.html#execution-results cc @minrk

@afshin, Completion: https://github.com/jupyter/notebook/blob/41d6da235cbf3bcf6d7f818e11a066e0fd12ff8b/notebook/static/notebook/js/completer.js#L173 Tooltip for inspection: https://github.com/jupyter/notebook/blob/41d6da235cbf3bcf6d7f818e11a066e0fd12ff8b/notebook/static/notebook/js/tooltip.js#L189

@minrk, ah, I see now "Payloads are considered deprecated, though their replacement is not yet implemented." This statement is confusing, I would say it isn't deprecated until there is actually...

@afshin, it looks like all of these will be relevant to you: http://jupyter-client.readthedocs.org/en/latest/messaging.html#payloads-deprecated

The output input, as it were.

Hi @jan-matthis, thank you, those are both excellent suggestions. We've moved development over to https://github.com/jupyter/jupyterlab. @afshin, do you want to migrate the top level comment over there and link to...

Migrated to https://github.com/jupyter/jupyterlab/issues/76

I would add the output area prompt overlay (which I didn't even know existed until I was trying to clone the notebook).
