Preview the map at the remote end of a topic hyperlink or relationship

Where I have a topic-to-topic link in a map, I would like to preview (or "peek") the destination branch without losing my current position. A pop-up window could show a small area around the destination topic. This would be very useful where a map contains reference information, e.g. definitions or legends that you want to quickly refer to.

For links within the same map, the Window split feature could be used and the destination topic shown in a split pane. The topic hyperlink context menu could contain a "Preview in split window" command.

The same could be done for relationships, allowing the remote end to be previewed.
