macOS 交换 Fn 键和 Control 键

September 09, 2015

下载 Karabiner

从 https://pqrs.org/osx/karabiner/ 下载 Karabiner，链接内含安装步骤

配置

选中如下项目：

Change Control_L Key (Left Control) 的子项 Control_L to Fn
Change Fn Key 的子项 Fn to Control_L
Fn+Functional Keys to F1..F12 的全部子项

Done!

如果接入外接键盘，此配置也会生效，可以切换多个配置文件来解决，但是会比较麻烦。我们可以自定 Karabiner 的选项，针对指定设备交换按键。App 目录下Contents/Resources/include/checkbox/standards/ 包含了程序自带的配置，作为参考。

获取键盘设备 ID 命令：

ioreg -n IOHIDKeyboard -r | grep -e 'class IOHIDKeyboard' -e VendorID\" -e Product

改好的 private.xml 如下：
