<p>Many mice and some touchpads have a middle mouse button. On a mouse
with a scroll wheel, you can usually press directly down on the scroll
wheel to middle-click. If you don’t have a middle mouse button, you
can press the left and right mouse buttons at the same time to
middle-click.</p>

<p>如果触摸板支持多指点按，您可以同时按三个手指来完成中键点击。您要在触摸板的设置中<link xref="mouse-touchpad-click">启用鼠标点击</link>。</p>

<p>许多程序用中键作为高级的快捷键。</p>

  <item><p>In the <gui>Activities</gui> overview, you can quickly open a new
  window for an application with middle-click. Simply middle-click on the
  application’s icon, either in the dash on the left, or in the applications
  overview. The applications overview is displayed using the grid button in the
  dash.</p></item>

  <item><p>Most web browsers allow you to open links in tabs quickly with the
  middle mouse button. Just click any link with your middle mouse button, and
  it will open in a new tab.</p></item>

  <item><p>在文件管理器中，中键有两种用法：如果您点击一个文件夹，它将在新标签打开，这类似于浏览器的行为，如果您点击的是文件，将会打开它就像双击一样。</p></item>
