  <title>警告音の代わりに画面をひらめかせる</title>

  <p>特定のメッセージやイベントにたいして簡潔な警告音が鳴ることがあります。この音が聞き取りづらい場合、警告音を鳴らす代わりに画面あるいは現在開いているウィンドウを視覚的にひらめかせることができます。</p>

  <p>This can also be useful if you’re in an environment where you need your
  computer to be silent, such as in a library. See <link xref="sound-alert"/>
  to learn how to mute the alert sound, then enable visual alerts.</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>Hearing</gui> section to open it.</p>
    </item>
    <item>
      <p>In the <gui>Visual Alerts</gui> section, switch the <gui>Visual Alerts</gui>
      switch to on.</p>
    </item>
    <item>
      <p>Under <gui>Flash Area</gui>, select whether you want the entire screen or just
      your current window title to flash.</p>
    </item>
  </steps>

  <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>視覚警告</gui>を選択すると、視覚警告のオン/オフを簡単に切り替えられます。</p>
