Need help for naming a switch on our website

I need help for naming a switch on our website.

Our company provides online education services. On our website, learners can view learning materials and content. The learning materials and content come with complete learning highlights and notes.

For one of the learning sections, the teacher is able turn on/off the learning highlights and notes. By doing so, the teacher assigns a 'special mode' which would only display highlights and notes the teacher would like students to learn.

My question is, how would you give a name to describe such a switch?

Would you call it a 'learning mode' or a 'key mode' in learning? Is there any better way to describe it?
