Unbinding Keyboard Shortcut in jupyter notebook

[Lorenz Braun]

Hello there,

i am using the jupyter notebook on my Mac with the German Neo 2 Layout. Unfortunately i can't type ':' because Cmd-d is bind to deleteLine.

I tried to remove the Shortcut by adding this to my notebook:

%%javascript

Jupyter.keyboard_manager.command_shortcuts.remove_shortcut('cmd-d');

 

Which yields this error:

Javascript error adding output!

Error: trying to remove a non-existent shortcut

See your browser Javascript console for more details.

 
I guess i need to change Cmd-d to something else but i can't figure out what it needs to be.
I also tried:
ctrl-d
meta-d
alt-d

Does anyone know what to put in there?

Kind regards
Lorenz

Hi Lorenz,

Delete line is not something bound by our shortcut system - I guess that's defined by Codemirror, the editor component we use. That's going to require totally different code for removing a shortcut, unfortunately.

Hi Thomas,

thanks for the quick answer. I was just wondering if i could not remove that shortcut, because iti s listed nowhere in the jupyter documentation. Seems that this is the case. That is really unfortunate =(

I worked around that problem by editing my keyboard layout so that : is bound to another key, which i don't need.

That's because it's a [CodeMirror][1] bound shortcut. There are ways
to unset it, likely though jupyter's `custom.js` files, but you will
have to figure out how to change the codeMirror KeyMap. It;s not
documented in Jupyter, because we can't re-document all of the
underlying libraries we use.
