More support for Azure Notebook

The following features and support are needed: 
・AZNB editing manual for teachers
・A list of shortcut keys available in AZNB (like Y, M to switch cell types, DD to delete cells, Alt+R to run all cells)
・Function to share AZNB between student-teacher (so that it can be executed with M:EE).

I teach MakeCode/Python to 18+ students at a technical school.
I was going to teach Python using Azure Notebook for students who have completed visual programming in MakeCode, but none of the editing, shortcuts, or sharing methods for preparing a course in AZNB seem to exist.
With better support around AZNB, it would be a good teaching tool as a lead-in from visual programming to text-based programming.

For example, AZNB is well suited for having students create and execute code step-by-step.
The teacher can prepare a notebook pre-colored with markup language, and students can run the prepared code with slight modifications, or follow the instructions in the markup cells immediately above.
For students entering the world of programming from visual programming, it is reassuring to know that programming instructions are right next to the same file, making it easy for them to try and error.
Students who understand the lesson quickly can also open the next tab in AZNB to learn the curriculum ahead. (I have not found a way to add tabs in AZNB, but there should be a way to add tabs, just as there are multiple tabs in the INTRODUCTION notebook!)
