@travigd@rubendibattista thinking a little bit more, I think we can probably add a keyboard shortcut to enable that... can you open an issue for that? (or find the related one where some of these things were discussed and add this to the discussion). Thanks!
@damianavila I was just thinking some kind of option in nbconfig/notebook.json (which I believe is the way the other RISE options are configured? I'm pretty new to RISE myself, I am but a humble proxy for a less technical faculty member)
But at any rate I can open an issue later today if you'd like me too. :)
