MOS 77-419 provide shortcuts to a mobile site URL??

I am studying for the MOS 77-419.

In the skills measured section of the link below under "Create and format content(25-30%)" section, I have a question in regards to "Manage lists and libraries".  In the bullet, it says "provide shortcuts to a mobile site URL".  How is that done?

I guess the appending /m to the url is what they're getting at.

In fact, after I posted I found this description of both mobile views they now provide;
