How does one navigate back after clicking an intra-document link? For example, consider the scenario of linking to reference materials. In Row Z, I enter the details of a particular reference. In Rows A through D, I discuss the subject matter and place one or more row links to Row Z as a means of citing a reference. Clicking on any of those links takes me to to the reference details found in Row Z. How does one navigate back to the row from which I original came?
