A keymap with such a vector is called a @dfn{full keymap}. Other keymaps are called @dfn{sparse keymaps}. +A @code{nil} binding is used to mean that a key is explicitly not bound. +Just like any other binding, it takes precedence over a default binding +or a binding in the parent keymap, but on the other hand, it does not +take precedence over keymaps of lower priority. + When a keymap contains a vector, it always defines a binding for each @sc{ascii} character, even if the vector contains @code{nil} for that character. Such a binding of @code{nil} overrides any default key |
