[FEAT] Cheatsheet implementation

[BooleanCube]

Describe the solution you'd like
Cheat sheet: https://www.reddit.com/media?url=https%3A%2F%2Fi.redd.it%2Flc0y2uahxngb1.png

I want to be able to log each key that is typed into the typing ground window in neovim, and then based on the keys found, determine what keys the user is not using that could be of help and inform them. This makes them aware of all tools and utilities that neovim has to provide and provides a nice way to gain productivity whilst coding on neovim.

Describe alternatives you've considered
Add an advice section explaining all the keys in the cheatsheet so its easy to consume for beginners.

Additional context
Would love to get some advice for any other useful keys you don't see on the linked cheatsheet.
