What key capability do Navigation Rules provide for related records in Salesforce?

Navigation Rules in Salesforce play a crucial role in guiding users on how to interact with related records, particularly when those records share relationships within the system. The primary capability of Navigation Rules is to determine the conditions under which additional records should be displayed to the user, based on the context of their current task or data entry. This means that users can dynamically see related records that are relevant to their current work, enhancing efficiency and ensuring they have access to the information pertinent to their current processes.

For example, if a user is viewing a case record, Navigation Rules can dictate that only related tasks or incidents associated with that case are displayed, rather than overwhelming the user with a long list of all related records. This targeted approach improves the user experience in navigating through related records by providing contextually relevant options, making it easier to access and manage related data efficiently.

The other options do not accurately reflect the foundational purpose of Navigation Rules, which is centered around conditional visibility rather than actions like opening in new windows, direct editing, or access restrictions. While those actions may pertain to record management in Salesforce, they are not the core function of Navigation Rules specifically.
