3.5 Documentation

GNU Emacs has convenient built-in help facilities, most of which derive their information from documentation strings associated with functions and variables. This chapter describes how to access documentation strings in Lisp programs. Documentation strings are specified in the definitions of the functions and variables they apply to.

This section also describes ‘ElDoc’ mode, and some help commands:

• Info-goto-emacs-command-mode
• documentation-property
• documentation
• describe-function
• describe-variable
• describe-symbol
