By default, new content items are added to the bottom of a Lesson Builder page. You can use the Reorder tool to arrange the content in any order.
To start, click the Reorder button at the top of the page. Drag and drop content items into your preferred order. Click Save to complete the process.
Note that it is also possible to use the keyboard to move items. Select the number to the left of the item, and use the control key, plus up-arrow or down-arrow. With certain browsers it may be necessary to key the arrows twice.
