We use a global setting to determine if Caps Lock should be remapped to Control because we don't care how keyboard events come in, just that they should be massaged into different scan codes. The `proc` filesystem is able to manipulate this global variable using the `sysctl` utility like so: ``` # sysctl caps_lock_to_ctrl=1 ```
