Throughout the Brightspace page templates, you will see copy: start and copy: end. If you want to duplicate an existing element, always select from copy: start to copy: end. This ensures the element is copied correctly and all styling remains intact.
This method can be used in all page templates that include copy: start and copy: end markers.
To duplicate a title section, select from copy: start to copy: end, then press CTRL + C.
Place your cursor where you want to insert the copied element, then press CTRL + V.
Below is also a video demonstrating how to copy and paste the element.
