Multiline navigation keybinding setup

General

Is there a way to configure shortcut key to move up and down the editor by 10 lines at a time instead of 1 line at a time?

Suggestions seems to be using a keybinding.json file. But this file doesn’t seem to exist and unsure on where its location is meant to be. (Using a mac).

Could I get some help with this pls.

The following is the suggested setting in that file. Yet to set it up considering am not sure if it should already exist and I don’t know the path, or if I need to create this file at a certain path, or if it differs for cursor vs vs code.

[
  {
    "key": "cmd+j",
    "command": "cursorMove",
    "args": {
      "to": "down",
      "by": "line",
      "value": 10
    }
  },
  {
    "key": "cmd+k",
    "command": "cursorMove",
    "args": {
      "to": "up",
      "by": "line",
      "value": 10
    }
  }
]
