To explore the words that have been used in the quotations linked to one or more codes, you can create a word list or word cloud. Word lists and word clouds are described in detail in the section Exploring Data.
To create a Word Cloud or Word List, select Analysis > Word List/Cloud from the main menu.
Set the type to Codes and select one or multiple codes from the list. You will see all words that occur in the quotations coded by the selected code(s) on the right-hand side. If you want to change to cloud view, click on the cloud button in the toolbar.
