Link Propositions Between Cmaps
From two open Cmaps:
You can link propositions between Cmaps that have been saved to either My Cmaps or Places. Begin connecting concepts and/or linking phrases between multiple Cmaps by first opening and positioning the Cmaps, so that overlapping is not a problem.
Two or more Cmaps can be linked to each other in much the same way as concepts and linking phrases connect to one another on a single Cmap. Left-click and drag from the arrows at the top of a concept or linking phrase, then release the mouse above a Cmap you want to link to.
Now when viewing the Cmaps, a concept appears on each Cmap with a shortcut arrow on its bottom right corner, indicating that the new concept links to another Cmap when left-clicked. Shortcut concepts, and any linking phrases or lines that they are connected to, can be modified to your liking. (The sections Create a New Proposition from One Concept and Create a Proposition from Existing Concepts further explore various connection possibilities that may also be used to connect multiple Cmaps.)
