Select multiple lines with cursors at each line start in Dr Racket

I want to select multiple lines and put a cursor at the beginning of each line in the code editor Dr Racket. I know that this is possible in VS Code and many others but I don't find a keyboard shortcut to do it in Dr Racket. Is it possible? How?

I tried:

• ctrl + shift + L and then put cursor at beginning of each line.
• option + shift + I.
• I'd love to have a solution for both Windows and MacOS.

DrRacket does not currently support multiple cursors, to the best of my knowledge.
