We do, see (info "(emacs) Minibuffer Edit"):

     Inside a minibuffer, the keys <TAB>, <SPC>, and ‘?’ are often bound
  to “completion commands”, which allow you to easily fill in the desired
  text without typing all of it.  *Note Completion.  As with <RET>, you
  can use ‘C-q’ to insert a <TAB>, <SPC>, or ‘?’ character.

and (info "(emacs) Completion Commands").
