<p> I am a long-time user of short-lived Emacs sessions who is now trying to take advantage of having a browser that runs for days or weeks at a time—I&#39;ve configured my desktop shell to auto-start <code class="verbatim">emacs –daemon</code> when I log in, and I rarely restart it (though it&#39;s probably still do it more often than a really hard-core Emacs user would).</p> <p> As a consequence, my minibuffer history starts to fill up with good stuff that I want to re-use in order to increase my efficiency.</p>
