They call it Fast Pass there, there's only some of the rides that have fast pass, and they are the more popular ones.
1) Go to the area of the ride you want to get fast pass for
2) Look at the fast pass schedule, it will say something like (13:30 - 14-30), means that your fast pass will be valid during that period, from 1.30pm to 2.30pm.
3) if it works for you (like if you are not intending to catch a parade or show or something during that time), go to the counters and scan your ticket QR code, and it will issue you the fast pass ticket.
4) return to the ride during that time to get fast pass access.
note that you can only get one pass pass per ride, and one fast pass every hr or 2, this depends on the time that is stated at the back of your fast pass ticket.
hope it helps!
