如何制作将选项卡向右切换的applescript

我试过使用代码

tell application "Google Chrome"
    activate
end tell

tell application "System Events"
    keystroke 124 using {command down, option down}
end tell

这个脚本有什么问题吗？因为命令选项箭头通常会切换选项卡

tell application "Google Chrome" 
    activate 
end tell

tell application "System Events" 
    key code 124 using {command down, option down} 
end tell
