You can export a topic or topics to create a new map using the Send To command. You may want to use this feature if:
Your map gets large and you want to "break off" topics to create a separate map.
You want to duplicate a topic or topics in a new map.
To export a topic and all its subtopics to a new map:
Right-click the topic
or
Select several topics and then right-click on one of them.
Click Send To - New Linked Map.
If you selected a single topic you can choose whether it will become the central topic or a main topic (branching off a new central topic) on the new map.
If you want to remove the topics from the current map, choose the Delete original topics and create hyperlinks to exported topics. The topics will move to the new map and hyperlinks will be added to the original map that point to the new map.
Otherwise, the topics are simply copied to create a new map but the original is left unchanged. (This produces the same result as copying the topics, opening a new map and pasting them.)
Maps that are linked together are called Multimaps. You can use the Multimap Workspace to see previews of all the linked maps and execute a variety of commands on them.
