title: emacs slime: Whats the equivalent of the up arrow in shells?
body: <p>When I type something wrong in dos/linux and it yells at me I can push the up arrow and then modify my line - maybe it was missing a '-' or something.  I just installed lispbox and up arrow moves the cursor up the REPL history.  How do i put on the current line the last line I entered.</p>
  
  <p>So like I type</p>
  
  <pre><code>+ 3 2
  </code></pre>
  
  <p>But obviously I meant </p>
  
  <pre><code>(+ 3 2)
  </code></pre>
  
  <p>How do I get it to say "+ 3 2" so I can just push "Home", "(", "End", ")"?</p>
  
  <p>Or is there some MUCH easier M-x waaahFIXIT command for this?</p>
