Most laptop touchpads make it possible to perform a middle-click, but not all do. In some situations, you may need to enable this option in your mouse driver’s control panel or install the appropriate drivers first.

大多数笔记本电脑的触摸板都可以执行中键单击，但并非全部都可以。 在某些情况下，您可能需要在鼠标驱动程序的控制面板中启用此选项，或者先安装适当的驱动程序。

To left-click on a touchpad, you click the pad with one finger. To right-click, you click the pad with two fingers. To middle-click, you click the pad with three fingers. That’s the ideal situation, anyway.

要在触摸板上单击鼠标左键，请用一根手指单击触摸板。 要右键单击，请用两根手指单击打击板。 若要单击鼠标中键，请用三个手指单击该打击垫。 无论如何，这是理想的情况。

In practice, this feature is enabled by default on some touchpads, disabled by default on others, and impossible to enable on some touchpads.

实际上，此功能在某些触摸板上默认为启用，在其他触摸板上默认为禁用，在某些触摸板上无法启用。

And, depending on your touchpad, you may just need to tap the pad with the correct number of fingers rather than physically clicking it down.

而且，根据触摸板的不同，您可能只需要用正确数量的手指轻敲触摸板即可，而无需物理地向下点击。

The below instructions are for Windows. On a Mac, you can use the MiddleClick application to enable middle-click with your MacBook’s touchpad.

以下说明适用于Windows。 在Mac上，您可以使用MiddleClick应用程序通过MacBook的触摸板启用中键单击。
