Update:
If anyone is watching this post, I added another related post here:
Comprehensive and Succinct List of Cursor Features
which links to a GitHub Page I put up here:
https://litecodeai.github.io/cursorfeatures
It is a work in progress, but it lists all the features I have come across as I learn Cursor.
And I am starting to add large annotated screenshots and short demo videos of each feature 
.
