Emacs is self-documented, as demonstrated on the response to your
previous inquiry. Additionally, it comes with a manual for the Emacs
Lisp language and for Emacs proper.
To learn more explore the contents of the Help menu in your Emacs.
If your question is about representing key sequences, see the "Key
Sequences" section on the Elisp Manual.
