      <p>Switch the <gui>Desktop Zoom</gui> switch to on.</p>
    </item>
  </steps>

  <note style="tip">
    <p>您可以通过点击在顶栏上的<link xref="a11y-icon">辅助功能图标</link>来快速启用或关闭<gui>缩放</gui>功能。</p>
  </note>

  <p>You can change the magnification factor, the mouse tracking, and the
  position of the magnified view on the screen. Adjust these in the
  <gui>Magnifier</gui> section.</p>

  <p>You can activate crosshairs to help you find the mouse or touchpad
  pointer. Switch them on and adjust their length, color, and thickness in the
  <gui>Crosshairs</gui> section.</p>

  <p>You can switch to inverted colors video, and adjust
  brightness, contrast and color options for the magnifier in the
  <gui>Color Filters</gui> section. The combination of these options is
  useful for people with low-vision, any degree of photophobia, or just
  for using the computer under adverse lighting conditions.</p>
