Are you fooling with me?
I feel that i should warn you that you'll be wasting your time trying to learn Archicad if you lack the insight to transpose backwards to a prior training guide once someone has even supplied the title of the article you need to see.
Guides are accessed through the "Help" menu as with any other software.
Also: You might now understand that when posting a question it is important to publish your software and hardware in your post signature to avoid wasting time since different Archicad versions sometimes have different solutions.
