Is this what you are talking about? Code -> Reformat Code:

option+command+L。

...Mac下大部分Window的Ctrl都可以用小菊花instead.

windows是Ctrl + Alt + L
Mac是小菊花 + Alt + L

option+command+L, just look at the Reformat Code in the code menu

I often use this function:
Windows is obviously ctrl + alt + L
Mac is command + alt + L
Why do some people always say the wrong answer? In addition, you can see the shortcut keys when entering the menu

cmd option l
建议配合.editorconfig
