What is the meaning of the green curved arrow in the Visual Studio code editor?

Question

If you go to this webpage, and scroll down:

http://www.unauthorised-access.com/category/nettiers/

You see a green U-turn like arrow. Does anyone know what this means? I read somewhere, a long time ago, it has something to do with threading and multi-threaded code but I can't remember.

Thanks

Answer 1

Isn't this simply a symbol to indicate that the line was wrapped by the source code formatter?

Answer 2

I think that's just showing a line break. The line with the green arrow should be on the same line as the one above, but it's been split because it is too wide for the page.
