自定义快捷键不生效

[iamqiz]

我改了assets\template\default.html 里的 toolbar 的redo 的快捷键为 ⇧⌘Z ,如下倒数第二行, 但是不生效
大佬帮忙看看怎么解决?

    const vditor = new Vditor('vditor', {
        "theme": darcula ? "dark" : "light",
        "height": document.documentElement.clientHeight,
        "lang": "{{Lang}}",
        "cache": {
            "enable": false
        },
