+While in the minibuffer, you can use \\<minibuffer-local-completion-map>\\[minibuffer-complete] and \\[minibuffer-complete-word] to complete your input.
+You can also use \\<minibuffer-local-map>\\[minibuffer-complete-history] to complete using history items in the
+input history HIST, and you can use \\[minibuffer-complete-defaults] to complete using
+the default items in DEFAULT-VALUE.

   DEFAULT-VALUE.  It normally should be nil in new code, except when
   HIST is a cons.  It is discussed in more detail below.
