// Place your key bindings in this file to overwrite the defaults
[
    {
        "key": "shift+cmd+s",
        "command": "workbench.action.files.saveAll"
    },
    {
        "key": "shift+cmd+s",
        "command": "-workbench.action.files.saveAs"
    },
    {
        "key": "cmd+b",
        "command": "editor.action.goToDeclaration",
        "when": "editorHasDefinitionProvider && editorTextFocus && !isInEmbeddedEditor"
    },
    {
        "key": "cmd+n",
        "command": "-workbench.action.files.newUntitledFile"
    },
    {
        "key": "cmd+n",
        "command": "workbench.action.quickOpen"
    },
    {
        "key": "cmd+ctrl+n",
        "command": "workbench.action.files.newUntitledFile"
    },
    {
        "key": "alt+cmd+l",
        "command": "editor.action.formatDocument",
        "when": "editorTextFocus && !editorReadonly"
    }

Windows Version:

        "command": "editor.action.formatDocument",
        "when": "editorTextFocus && !editorReadonly"
    },
    {
        "key": "ctrl+b",
        "command": "editor.action.goToDeclaration",
