Jquery scrolling or sliding div with overflow?

Question

I'm trying to make a a fairly simple jquery function to slide through some "tweets" with varying heights. I've tried numerous carousel / slider plugins but none of them seem to allow for simple continuous scroll onmousedown, and they are all tied to animating from one "slide" item to the next. There is jScrollPane but it seems impossible to style without a scroll bar (I;m looking only to use arrows). Overflow: auto isn't an option :)

This seems like it should be a a fairly simple thing, but I can't seem to find any plugins that accomplish this -- any ideas?

#scroll-container {
  positon: relative;
  overflow: hidden;
  height: 300px;
  width: 200px;

#scroll-region { 
  position: absolute
}

<div id="scroll-container">
  <ul id="scroll-region>
    <li class="item"></div>
    <li class="item"></div>
    <li class="item"></div>
    <li class="item"></div>
    <li class="item"></div>
  </ul>
</div>

<div id="actions>
  <a href="#" class="next>Next</a>
  <a href="#" class="next>Prev</a>
</div>
