## The rail order

The order of scenes in the left rail is the order learners walk
through with next/previous. Drag to change it.

This order is load-bearing for one activity: **Order the sequence**
hands learners your scenes shuffled and asks them to put them back,
marking against the rail order. If you reorder scenes after learners
have attempted it, earlier attempts were marked against the old
answer — say so, or reset the activity.

## Jump links

A pin can link to another scene. That is how you build spatial
navigation: a pin on the doorway of the lobby scene that jumps to the
corridor scene. Learners follow the space rather than a list.

Jump links are what **Wayfinding challenge** uses. If you plan to use
that activity, build the links as a real map of the building rather
than a convenience shortcut, or the "shortest path" it measures
against will not mean anything.

## The cover

The cover is what a learner sees before they enter. Give it a title, a
short description and an image that makes it obvious what this is.
