Control mode is a minor mode for Emacs that provides a
"control" mode, similar in purpose to vim's "normal" mode. Unlike
the various vim emulation modes, the key bindings in Control mode
are derived from the key bindings already setup, usually by making
the control key unnecessary, e.g. "Ctrl-f" becomes "f". This
provides the power of a mode dedicated to controlling the editor
without needing to learn or maintain new key bindings. See

documentation.
