If you are using PMP, I have something for you.  
This was posted while PMP was still Plex Pass-only. So you might haven’t seen it yet.

This is done by copying the keyboard.json file from the inputmaps/examples/ folder to the inputmaps/ folder and changing it in a text editor.  
[https://support.plex.tv/hc/en-us/articles/216459997-Create-your-own-inputmap](https://support.plex.tv/hc/en-us/articles/216459997-Create-your-own-inputmap)

edit the file, seek the line  
`"\\-": "decrease_volume",`  
and add this line directly underneath it:  
`"Ctrl\\+D": "host:player af toggle lavfi=[acompressor]",`

now you can toggle ‘Night Mode’ with CTRL+D while playing a movie.

I wouldn’t want to listen to music with this active, but for movies it works pretty well.
