In this issue I will focus on working on my own system to handle the brightness and volume key. I will also allow the key to be pass-through, meaning that if your current screen is a native display, the app will simply pass the command to macOS default, changing the brightness/volume natively.

Hopefully this will fix the following issues :

• Karabiner Elements dependency
• Using the shortcut keys while in an app making use of the same shortcuts would result in the app registering the shortcut too.
• You could not change a native display brightness/volume using Karabiner Elements as it would override the default key.

I'll update the issue when the dev of the features discussed will be completed.
