鼠标左键成了右键快捷键
Most mice have two main buttons: the primary button and the secondary button. The primary button is usually on the left side of the mouse, but some users prefer to swap them if they are left-handed or have a different preference. Here’s how to do that on your Mac.
大多数鼠标都有两个主按钮：主按钮和辅助按钮。 主按钮通常位于鼠标的左侧，但是如果某些用户习惯用左手或具有不同的首选项，则希望将其交换。 这是在Mac上执行此操作的方法。
First, open System Preferences by clicking on the Apple logo on the menu bar then selecting “System Preferences.”
首先，通过单击菜单栏上的Apple徽标，然后选择“系统偏好设置”，打开“系统偏好设置”。
In System Preferences, locate “Mouse” and click on it. This will open the mouse options.
在系统偏好设置中，找到“鼠标”，然后单击它。 这将打开鼠标选项。
In Mouse options, find the “Primary Mouse Button” section, then select either Left or Right depending on your personal preference. The default primary mouse button is Left, but some right-handed users use the Right button as primary.
在“鼠标”选项中，找到“主鼠标按钮”部分，然后根据您的个人喜好选择向左或向右。 默认的主鼠标左键是“左”，但是一些惯用右手的用户将“右键”用作主鼠标。
The secondary button is usually used for what many people call “right-clicking,” which is another way to bring up contextual menus or other options with the mouse.
辅助按钮通常用于许多人所说的“ 右键单击 ”，这是用鼠标调出上下文菜单或其他选项的另一种方法。
Now you can close System Preferences, and your option will be saved. You can always change it back at any time by visiting System Preferences > Mouse again. Happy clicking!
现在，您可以关闭“系统偏好设置”，并且您的选项将被保存。 您始终可以随时通过再次访问系统偏好设置>鼠标将其更改回去。 点击愉快！
