title: CTRL+mouse wheel in gvim (windows) not paging
body: <p>I'm loving vim, but one thing that's bugging me is that when I hold the control key and mouse wheel up or down, the window scrolls normally when the bindings are telling it to page up/down. </p>
  
  <p>I'm using the exact same vimrc file (and plugins) on one of my linux machines and the CTRL+mouse wheel does page up down (as opposed to just normally scrolling like in windows).</p>
  
  <p>Is there some way to force gvim to response to a ctrl+MouseUp/Down event? It seems to be ignoring it in windows ='[</p>
