  <title>Moving around a document</title>

  <!-- TODO: split into smaller pages for 3.14 -->
  <p>You can move around each page of a document by any of the following
  methods:</p>

  <list>
    <item>
      <p>Scrolling up and down using the mouse wheel. To move around a page

      <steps>
        <item>
          <p>Right-click the page and select <gui>Autoscroll</gui>.</p>
        </item>
        <item>
          <p>Move the mouse pointer towards the bottom of the window to scroll
          down; it will scroll faster depending on how far down the window you
          go.</p>
        </item>
        <item>
          <p>To stop autoscrolling, click anywhere in the document.</p>
        </item>
      </steps>
    </item>
    <item>
      <p>Using the scroll bar on the document window.</p>
    </item>
    <item>
      <p>Using the up and down arrow keys of your keyboard.</p>
    </item>
    <item>
      <p>Dragging the page around with your mouse, as if you are grabbing it.
      To do this:</p>
      <list>
        <item>
          <p>Move the mouse pointer over the page and hold down the middle
          mouse button to drag it around.</p>
        </item>
        <item>
          <p>If you don't have a middle mouse button, hold down the left and
          right mouse buttons at the same time, then drag.</p>
        </item>
