You can autoload macros and keymaps as well as ordinary functions.

An autoloaded keymap loads automatically during key lookup when a prefix
key's binding is the symbol @var{function}. Autoloading does not occur

with those symbols. (Loading saves these in the @code{autoload}
property of the symbol.)
