There are four different screens available after selecting Start Labeling:
In the List view there are all documents of a Candidate Set listed. As an overview you see all titles, highlights and already tagged extracts of the documents of the selected Candidate Set. The document can get tagged and studied more in detail on the right side. In the left panel you can switch between different Candidate Sets.

The proximity rule can get defined after tagging an text extract, if the Define Proximity Search rules option is activated in the configuration of the Ground Truth.
...
In the Focus view screen you get directly guided to the highlighted section in the documents of the Candidate Set.
