electric-buffer-menu-mode is an interactive compiled Lisp function in `ebuff-menu.el
'.
(electric-buffer-menu-mode)
Parent mode: `Buffer-menu-mode'.
Toggle Electric Buffer Menu mode in this buffer.
With a prefix argument ARG, enable Long Lines mode if ARG is
positive, and disable it otherwise. If called from Lisp, enable
the mode if ARG is omitted or nil.
Electric Buffer Menu mode is a minor mode which is automatically
enabled and disabled by the M-x electric-buffer-list command.
See the documentation of `electric-buffer-list' for details.
In addition to any hooks its parent mode `Buffer-menu-mode' might have run,
this mode runs the hook `electric-buffer-menu-mode-hook', as the final step
during initialization.
