Jupyter doesn't let me type the left square bracket

Question

Recently I have installed Jupyter Notebook on my Mac for didactical use and I've noticed a problem: doing list = Jupyter doesn't let me type the left square bracket, and if I type that in a new line it allows me to type, for example:

[]

I've just tried to reinstall completely Jupyter from the prompt using Homebrew and it doesn't worked. How can I do?

This is a known issue:

You can do:

Settings → Settings Editor → JSON Settings Editor → Keyboard Shortcuts → User → paste → save

paste:

{
  "shortcuts": [
    {
      "args": {},
      "command": "inline-completer:next",
      "keys": [
          "Alt ]"
      ],
      "selector": ".jp-mod-completer-enabled",
      "disabled": true
    },
    {
      "args": {},
      "command": "inline-completer:previous",
      "keys": [
          "Alt ["
      ],
      "selector": ".jp-mod-completer-enabled",
      "disabled": true
    },
    {
      "args": {},
      "command": "inline-completer:invoke",
      "keys": [
          "Alt \\"
      ],
      "selector": ".jp-mod-completer-enabled",
      "disabled": true
    }
  ]
}

As @everson commented please restart your notebook after changes.
