From an open Cmap:
You can get a list of suggestions for concepts to add to a Cmap. The CmapTools Suggester is available to use once you have accessed one or more items on the Cmap, and at least a few concepts or linking phrases on the Cmap are labeled. To begin gathering suggestions for a Cmap, either select Concepts from the Suggestions submenu under Tools, or click the Suggestions button (This button may also be used to expand or collapse the Suggestions console).
The Suggestions console opens to the side of the Cmap you are working on. Click the blue arrows button to obtain a list of suggestions relative to the latest contents of the Cmap.
Click the stop and go button to change the red indicator light to green if you want to allow the suggester to automatically refresh the list of suggestions as the Cmap changes, otherwise the suggester will only refresh the list when you click the blue arrows button. You can drag and drop individual concept suggestions from the list that appears onto the Cmap using the mouse.
A concept that has been dragged and dropped onto the Cmap appears as new concept.
