The echo area is used for displaying error messages
(see Errors), for messages made
with the message primitive, and for echoing
keystrokes. It is not the same as the minibuffer, despite the
fact that the minibuffer appears (when active) in the same place
on the screen as the echo area. See
The Minibuffer in The GNU Emacs Manual.
Apart from the functions documented in this section, you can
print Lisp objects to the echo area by specifying t
as the output stream. See Output Streams.
