explains how to customize key bindings, which is done by editing your
init file (@pxref{Init Rebinding}).
Since most modes define their own key bindings, activating a mode
might override your custom key bindings. A small number of keys are
reserved for user-defined bindings, and should not be used by modes,
so key bindings using those keys are safer in this regard. The
reserved key sequences are those consisting of @kbd{C-c} followed by a
letter (either upper or lower case), and function keys @key{F5}
through @key{F9} without modifiers (@pxref{Modifier Keys}).
