Question

I have the following configuration for shortcuts, that works after running it in the cell of Jupiter notebook:

%%javascript


IPython.keyboard_manager.comman         


        

Answer 1

1. For changing command mode shortcuts: refer Salvador's answer

2. For changing edit mode shortcuts:

Edit the file, ~/.jupyter/nbconfig/notebook.json as explained on https://jupyter-notebook.readthedocs.io/en/stable/extending/keymaps.html

For example, after replacing the control-enter shortcut to execute code, with command-enter on macOS, the file looks like this:

{
  "Notebook": {
    "Toolbar": true,
    "Header": true
  },
  "Cell": {
    "cm_config": {
      "lineNumbers": true
    }
  },
  "keys": {
    "command": {
      "unbind": [
        "ctrl-enter"
      ],
      "bind": {
        "cmdtrl-enter": "jupyter-notebook:run-cell"   
      }
    }, 
    "edit": {
      "unbind": [
        "ctrl-enter"
      ],
      "bind": {
        "cmdtrl-enter": "jupyter-notebook:run-cell"
      }  
    } 
  }   
}
