Undefine

Editor Command

Argument: None
Key sequence: None

Without a prefix argument, this undefines the current top level definition. That is, the defining form around or preceding the current point.

With a non- nil prefix argument, this does not undefine the definition but instead inserts into the buffer a Lisp form which, if evaluated, would undefine the definition.
