Nextion Scereen with button

Hi, guys
I wanna do a program using a nextion screen. I have 12 pages in my nextion display and I want to use 12 buttons to change each page of the nextion display, I want to use each button for each page of the nextion display. I want to press button one and change to page one , and press button two and change to page two until page 12. I´ve been looking for a tutorial or something but I don´t find nothing. Any advice?
Thanks

Have a search of the displays section of the forum-Perry has done a lot of work here.

Google …..

Thanks man
