Is there an easy way to browse through command history and reuse old commands in a Jupyter notebook? Some equivalent to either the arrow up/down use in the iPython console or to the % sign use in Mathematica. (Although the answer might seem trivial to an expert, it is really hard to find for a newbie)
I was looking for the same. But a year later, and after about 10 min of scouring the best I found (link) is this magic command: %recall last or %recall <integer>, which after execution copies a command from history into a new cell. Probably not quite what you had been looking - a tad too kludgy compared to arrow up/down. But a good option for cells with lots of text.
