Navigate in the loop 

When you (or your students) move around in a loop, there are some different ways of doing that. If you click a hub, the hub panel will unfold and there you can choose shortcuts to the different nodes at that very hub by clicking names or symbols. You can also move on to the other hubs that are connected to the hub you are currently at, by clicking their hub images or names. Another way is to click the nodes directly in the map to come to them and to navigate between the hubs by grabbing the map and pulling it sideways to reach the hub you want.
