我还是不添加下划线了。您采用的编写形式，让我这个对编写程序完全空白的人，能够尽情的尝试，不必担心调用出现错误而无法恢复。我将把如何修改菜单显示的方法告诉了一些有需要的使用者，让他们自己能够自由的定制需要的脚本菜单这比max的菜单容易得多。
（max实现下划线功能可能是使用了多个var internalcmd 我无法弄清楚这和下划线的位置规则具体的关联）
I still won't add an underline. The writing style you have adopted allows me, as someone who is completely blank in programming, to try it out without worrying about errors in the calls and being unable to recover. I will tell some users in need how to modify the menu display, so that they can freely customize the script menu they need, which is much easier than Max's menu.
(Max's implementation of the underline function may be due to the use of multiple var internalcmd, and I cannot figure out the specific association between this and the position rule of the underline)

再次感谢您制作的菜单。简便而明确。（Thank you again for creating the menu. Simple and clear.）
