How to display a layer in Outline or Wireframe mode?!?

Hello everyone,

I'm working with Illustrator CSS and I want to switch a layer to Outline mode.

Before, you just had to use the shortcut Ctrl + click on the eye of the relevant layer. The eye would become empty, it was simple and practical!

I've been trying every possible way for the past hour, but it doesn't work in my CSS version. And I haven't found anything on the web.

Does anyone know the new method?

Thanks in advance to everyone! ;)
