Using the Dictionary and Thesaurus
NOTE! Dictionary and Thesaurus currently only works in Cmaps with text written in English.
From an open Cmap:
Select Tools, then Dictionary and Thesaurus...
You will now see the Dictionary and Thesaurus window.
In the top left text input, enter the word or term you wish to look up, and click the Look Up Related Word button.
You will now see all the alternatives for the word you just looked up.
If you had a concept selected when you started this process, you can simply click Replace, and the word will be replaced with your new selection. Otherwise, you can click the Add as a New Concept and a new concept will be created with your selected word.
