Jupyter Notebook Ctrl+Shift+- (splitting cell) does not work

Ctrl + Shift + - is supposed to split the cell from where the cursor is, but it just zooms out the window.

If your keyboard has more than one key corresponding to -, and one zooms out instead of splitting cells, try using the other key.

On Linux, Ctrl-Shift-Minus zooms out, and takes priority over the jupyter setting.

To change the binding, edit ~/.jupyter/nbconfig/notebook.json and insert the following immediately before the final close curly brace:

 , "keys": { "edit": { "bind": { "Ctrl-\\": "jupyter-notebook:split-cell-at-cursor" } } } 

This changes it to Ctrl-Backslash.

If you want to change a command mode keybinding, replace "edit" above with "command".

You can find the list of functions to bind to in the sources at:

On Mac it is actually:

control ⌃ + shift ⇧ + -

and it does not zoom out, unless you press ⌘ instead.
