title: VIm : How to use only the "mouse scrolling" without the other feature of :set mouse=a
body: <p>I just discovered <code>:set mouse=a</code>. Amazing thing, it allows my coworkers to scroll over my openend files. </p>
  
  <p>But here is the thing : I really don't want the cursor to move when I left-click somewhere. I don't want either the standard cursor which <code>:set mouse=a</code> brings (I want to keep the default text cursor).</p>
  
  <p>In others words : is there a way to <strong>enable mouse scrolling</strong> in VIm <em>without</em> enable other support mouse stuff ?</p>
  
  <p>Thanks.</p>
  
  <p>EDIT - <strong>other idea</strong> : can I bind the <code>wheel mouse UP</code> to do the same thing that <code>Page Up</code> key ? It would be awesome !</p>
