Up/Down keys don't work to "Search previous command history" (besides Ctrl-p/Ctrl-n)

[franciscolourenco]

Both Ctrl-p/Ctrl-n and Up/Down work when nothing is typed.
However when something is typed in, only Ctrl-p/Ctrl-n work to search through history, while Up/Down does nothing.

This issue is for the binding of the Up/Down keys to the "Search previous command history" action, when things are typed.

Thanks

Up/Down are bound to history-search-backward/forward, so they scroll through your history based on shared prefix.

Yes, you are right, this is already working as expected.
Sorry for the mistake.

No problem. All of this functionality is provided by readline, not IPython, so it should behave in a similar manner to many other shell programs.
