The Text Mapper allows users to divide the text data of a particular data category of an entry into substrings, so that relations can be created not only between data categories but also between parts of them. To do that, drag the data category of en entry into the Edit in Text Mapper box. The text will be displayed in a new window. In order to create a substring, mark the relevant part of the text with the mouse cursor.

The substring will appear in the bar at the bottom of the page. You can either save or delete them. The next time you will drag this item into the Show in Knowledge Space or Add to Knowledge Space box you will be asked whether you want to view the whole text or only one of the defined substrings. The same will happen if you drag it either to the Source or Target box, so that you can decide for which parts of the text you want to create relations.
