# Referencing an area of the course material

The post-it icon is one of the most popular features used by Amanote users, enabling links to be created between the course material and the note-taking area. A numbered dot can be freely placed on the course material page to add clean, structured notes for this part.

This is particularly useful for annotating diagrams, images or charts.
