How to close the doc reading part of the IPython notebook?

Question

In an IPython notebook, when you look at some docs with ? or help(), a split frame is opened at the bottom of the screen where the documentation shows up. While I find this useful as a guide for continuing to play with some Python code, I would like to close this spit frame when I'm done reading the docs, so to get back the screen space. But I can't find instructions anywhere, not with Google and not in the IPython notebook docs how to do this?

Anybody knows?

Answer 1

Doh, one has to click on the very slim divider line. The subframe then closes...

Answer 2

You have to press the q key. That works for me.
