26.2 Top-Level Definitions, or Defuns

In Emacs, a major definition at the top level in the buffer, such as a function, is called a defun. The name comes from Lisp, but in Emacs we use it for all languages.

• Left Margin Paren		An open-paren or similar opening delimiter starts a defun if it is at the left margin.
• Moving by Defuns		Commands to move over or mark a major definition.
• Imenu		Making buffer indexes as menus.
• Which Function		Which Function mode shows which function you are in.
