中文说明

左cmd的 右cmd在自定义快捷的？

@BitionSong 没明白你说的是什么意思？

@BitionSong没明白你说的是什么意思？
左cmd+空格键和 右cmd+空格键可以修改为其他app的快捷键吗？
需要怎么修改呢？

@BitionSong 可以的，以左 Command (⌘) 为例，主要就是修改 32-36 行 为你想要的快捷键，然后去除 8-17 行的条件规则。

具体请自行参考 Karabiner-Elements 的文档和规则样例：

新版kb有点不兼容左control大写，希望测试一下

@llity
可以调整一下规则的顺序，先把ctrl映射到caps, 再把caps映射到escape和control
