I've already added it to the development version of the manual:  
   https://librecad-docs-dev.readthedocs.io/en/latest/ref/fundamentals.html#drawing-and-editing-entities  (See "Using the Keyboard")

As a FYI, I follow a release of the application with a release of the manual to keep things aligned.
