  <title>画面を拡大表示する</title>

  <p>画面を拡大表示することは、<link xref="a11y-font-size">文字のサイズ</link>をただ大きくするだけではありません。これは、ルーペを使って画面を見るような機能であり、画面の一部にズームインして画面上を移動できようになります。</p>

  <steps>
    <item>
      <p>Open the <gui xref="shell-introduction#activities">Activities</gui> overview and
      start typing <gui>Accessibility</gui>.</p>
    </item>
    <item>
      <p>Click on <gui>Accessibility</gui> to open the panel.</p>
    </item>
    <item>
      <p>Select the <gui>Zoom</gui> section to open it.</p>
    </item>
    <item>
      <p>Switch the <gui>Desktop Zoom</gui> switch to on.</p>
    </item>
  </steps>

  <p>これで画面上を移動できるようになります。画面の端へマウスを動かすことで拡大した領域が様々な方向へ移動し、お好みの場所を表示することができます。</p>

  <note style="tip">
    <p>トップバーの<link xref="a11y-icon">アクセシビリティアイコン</link>から、<gui>ズーム</gui>を選択すると、ズームのオン/オフを簡単に切り替えられます。</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>
