Command history in Interactive Window

[leifwalsh]

When using the Interactive Window, I'd like to be able to reuse previous inputs, like I'd do in a shell like bash or a command line Python or IPython REPL, so I can rerun previous input cells, or edit them slightly before running again.

I'd like to be able to access these with keyboard shortcuts that are familiar to how I use interactive shells in a terminal, so I'd expect something close to readline support (up/down arrow keys to go back and forward in command history, Ctrl-P/Ctrl-N if I'm using Emacs keybindings, or j/k if I'm using Vim keybindings). Even better would be command search like Ctrl-R for searching backwards through history. See https://readline.kablamo.org/emacs.html for inspiration too.

It might also be interesting to be able to navigate through the output window above the prompt, maybe as something like a read-only buffer, but one where you can select and copy previous inputs (or maybe also outputs) from it. Again, ideally accessible only via keyboard shortcuts, for people who try to avoid the mouse :)

Thanks for the suggestion.
Using the up/down keys in the Interactive Window's input box currently navigates through previously run commands, but only if they were run in the input box - Are you suggesting that cells run from the .py file should also be included in that list?

Also, take a look at #4716 which I think covers part of what you're looking for.

Hmm, up/down doesn't do that for me, but it could be my keybinding extension (tuttieee.emacs-mcx) getting in the way. I'll try disabling it and poking around.

#4716 does cover the readline stuff I was talking about, and the rest of this issue is just a problem with my installation, so let's close this. Thanks for the quick answer!

[leifwalsh]

Yeah, adding a new C-p and C-n keybinding to interactive.history.{next,previous} helped, but I'm not sure what was capturing that before.

This is broken for me when using Vim. I'd like to be able to use K and J like up and down to access previously run input boxes, but it doesn't work. Maybe because I have K and J mapped to g-k and g-j (for navigating on wrapped lines)

@kjohnsen can you open a new issue for what you're seeing and those specific settings
