 <h2 class="chapter">Minibuffers</h2>    <p>A <em>minibuffer</em> is a special buffer that Emacs commands use to read arguments more complicated than the single numeric prefix argument. These arguments include file names, buffer names, and command names (as in <kbd>M-x</kbd>). The minibuffer is displayed on the bottom line of the frame, in the same place as the echo area (see <a href="the-echo-area">The Echo Area</a>), but only while it is in use for reading an argument. </p> <table class="menu" border="0" cellspacing="0"> <tr>
