安装脚本插件如Violent Monkey，然后添加如下脚本：

// ==UserScript==
// @name AiStudio shortcut
// @namespace Violentmonkey Scripts
// @match https://aistudio.baidu.com/*/notebooks/*
// @grant BienChen
// ==/UserScript==
// 
// 
(function () {
  function sleep(ms) {
    return new Promise(resolve = > setTimeout(resolve, ms));
  }
  
  async function runAll(e) {
    // this would test for whichever key is 82 (r) and the meta key at the same time
    if (e.metaKey && e.keyCode == 82) {
      run_button = document.querySelectorAll('.notebook-header-menu-list.ant-dropdown-trigger') [2]
      if (run_button.textContent == '运行') {
        constevt = new MouseEvent('mouseover', {
          'view': window,
          'bubbles': true,
          'cancelable': true
        })
        run_button.dispatchEvent(evt);
        awaitsleep(500);
        button_list = document.querySelectorAll('div.h-m-i-btn')
        for (var i = button_list.length; i--; ) {
          if (button_list[i].textContent == '全部运行') {
            button_list[i].click();
          }
        }
      }
    }
  }
  
  async function restartKernel(e) {
    // this would test for whichever key is 81 (q) and the meta key at the same time
    if (e.metaKey && e.keyCode == 81) {
      run_button = document.querySelectorAll('.notebook-header-menu-list.ant-dropdown-trigger') [3]
      if (run_button.textContent == '环境') {
        constevt = new MouseEvent('mouseover', {
          'view': window,
          'bubbles': true,
          'cancelable': true
        })
        run_button.dispatchEvent(evt);
        awaitsleep(500);
        button_list = document.querySelectorAll('div.h-m-i-btn')
        for (var i = button_list.length; i--; ) {
          if (button_list[i].textContent == '重启环境') {
            button_list[i].click();
          }
        }
      }
    }
  }
  
  async function saveResult(e) {
    // this would test for whichever key is 83 (s) and the ctrl key at the same time
    if (e.metaKey && e.keyCode == 83) {
      button1 = document.querySelectorAll('.notebook-header-menu-list.ant-dropdown-trigger') [0]
      if (button1.textContent == '文件') {
        constevt = new MouseEvent('mouseover', {
          'view': window,
          'bubbles': true,
          'cancelable': true
        })
        button1.dispatchEvent(evt);
        awaitsleep(500);
        button_list = document.querySelectorAll('div.h-m-i-btn')
        for (var i = button_list.length; i--; ) {
          if (button_list[i].textContent == '保存') {
            button_list[i].click();
          }
        }
      }
    }
  }

  window.addEventListener('keyup', restartKernel, false);
  window.addEventListener('keyup', runAll, false);
  window.addEventListener('keyup', saveResult, false);
}) ()

其中Meta键（win键）+ r 是全部运行，Meta键+ s 是保存文件，Meta键+ q 是重启环境。
