Appendix G Buffer-Local Variables

The table below lists the general-purpose Emacs variables that automatically become buffer-local in each buffer. Most become buffer-local only when set; a few of them are always local in every buffer. Many Lisp packages define such variables for their internal use, but we don't try to list them all here.

Each minor modes defines a buffer-local variable named `modename-mode'. See Minor Mode Conventions. Minor mode variables will not be listed here.
