Conceptual navigation
From LSWiki
Conceptual navigation occurs during teleportation, such as planeswalking, reading scrolls of recall, or invoking the traveler ability.
CN is a multiple-choice "mini game" used to reach one's destination. Choosing the initial Left or Right determines whether the CN will be vocabulary or mathematics, respectively. The next L R U D choice (difficult) determines how much time it takes between questions. That is, easier questions have a longer delay between them, while harder questions have less delay.
After answering 3 correct questions in a row, the I option allows one to complete the teleport.
