body: <p>I would like to use dabbrev completion in icicles as mentioned in the following page.</p>

  <blockquote>
    <p>If user option `icicle-top-level-key-bindings’ contains an entry for
    ‘dabbrev-completion’ then Icicles remaps keys normally bound to
    command ‘dabbrev-completion’ to command ‘icicle-dabbrev-completion’,
    which uses Icicles completion whenever there are multiple completion
    candidates. You can then use any Icicles features, such as apropos
    completion and candidate cycling. In addition, you can complete an
    empty prefix, starting from scratch with apropos completion.</p>

  <p>However I don't understand how to set the 'icicle-top-level-key-bindings' in my .emacs file.
  I tried a number of steps that didn't work.
  'M-x describe-variable RET icicle-top-level-key-bindings' shows me a list with lot of options. How could I add ‘dabbrev-completion’ to this existing list.</p>
  
  <p>I got the icicle library from <a href="http://www.emacswiki.org/emacs/Icicles_-_Libraries" rel="nofollow">http://www.emacswiki.org/emacs/Icicles_-_Libraries</a></p>
  
  <p>I also see following code in <a href="http://www.emacswiki.org/emacs/icicles-opt.el" rel="nofollow">icicles-opt.el</a></p>
  
  <pre><code> (dabbrev-completion icicle-dabbrev-completion
                       (&lt; emacs-major-version 24))
  </code></pre>
  
  <p>Does it mean dabbrev mode is not supported in emacs2.4.3 ?</p>
