Text Blocks are used to create Inline Interactions. A text block is basically a paragraph, and forms a framework into which one of the two available text-based inline interactions (Inline Choice, Text Entry) is then inserted.
1. Using Text Blocks with Inline interactions
This creates a field (containing a sample text) in which a text may be entered from a favorite source (you can copy and paste text from any text editor, or website, for instance), or typed in.
To enter your text, click inside the text field.
Note: See the section on Interaction Authoring Tools for details on text editing options such as using italics or bold text in your item, and inserting features such as shared stimuli or media, tables or formulae.
