您一定已经注意到键盘顶部的整行都有F1-F12 的^(F1-F12)标签。您会在每个键盘上找到这些键，无论是Mac^(Macs)还是 PC。这些键可以执行不同的操作，例如 Fn 锁定键在按住时执行单独的功能，因此您可以使用 Fn 键的辅助操作，您可以在键盘顶部的数字键上方找到该键。这些 Fn 键的其他用途是它们可以控制亮度、音量、音乐播放等。

但是，您也可以锁定 Fn 键；这类似于大写锁定，打开时，您可以写大写字母，关闭时，您会看到小写字母。同样，当您锁定 Fn 键时，您可以使用 Fn 键执行特殊操作，而无需按住 Fn 锁定键。因此，如果您已启用 Fn 锁定键，我们将在此处提供一个小指南，您可以按照该指南了解 如何在 Windows 10 中使用 Fn 键锁定。^{(how to use the Fn key lock in Windows 10.)}
