As an author in Build, you can create an internal link to another unit in your course. This allows you to direct a learner to a previous unit to reinforce an important point covered previously, or it can serve as a refresher of information already covered in the course.
To add an internal link to your learning content, enter Editing mode and click the Internal link button in the text editor toolbar.
In the dialogue box, you can add an introduction to your internal link and you can select the unit that you wish to create a link for. The introduction gives the learner a brief description of why the linked unit is important to review.
Internal links are identifiable by a 3-point link icon on the left hand side of the channel in which the text is placed in.
