38.4 The Echo Area

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.

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.
