Feature request: scroll line up/down using keyboard shortcut

[jsh9]

Hi!

I've found that vscode and pycharm have a quite neat feature, which is to scroll down/up one line per key press, using ctrl + up/down.

Here is vscode's keyboard shortcut: https://code.visualstudio.com/docs/getstarted/keybindings (seacrh for "scrollLineDown"), and PyCharm has the same keyboard shortcut.

Currently, Spyder's ctrl + up/down is reserved for navigating between different code cells, so I wonder if we can have a line-by-line scroll assigned to another keyboard shortcut?

Again, a nice suggestion of yours but unfortunately we don't have time to implement it. You're welcome to submit a PR for it though.

I think this would be a nice feature to have for the editor.

The hard part is to find a proper key sequence that everyone will agree with...

[jnsebgosselin]

Maybe we could use Ctrl+Shift+Up and Ctrl+Shift+Down?

@goanpeca any thoughts?

[jsh9]

Psychologically, ctrl + up/down feels more incremental, and ctrl + shift + up/down feels more like a bigger step. If we are OK with breaking past user behaviors, I'd say assign ctrl + up/down to "scroll by line", and ctrl + shift + up/down to "navigate by cell".

@jsh9, you can easily remap shortcuts to your convenience, so I don't think that's necessary.

Ok I can take care of that one, I've tested it and it is simple to implement.

Sure, thanks a lot for your help @jnsebgosselin!

I think new, non-critical features should go for Spyder 5. So please create your branch from master.
