How do I create a link to an activity in a text box?
Tip: If you are creating a text box in the Lessons tool, you may also insert activities directly as individual items on the page, rather than within the Rich Text Editor. See How do I add activities to Lessons? for more information.
Select the text to be linked.

In the text box, select the text you would like to serve as a link to the activity.
Click Browse Server.

This displays the Entity Picker. If you have any Forums, Assignments or Test & Quizzes posted, they will be displayed in the Entity Picker.
