This question already has an answer here:
I found this article:
According to changing between multiple opened documents in LibreOffice and Chrome.
But I was testing in macOS Sierra with Spanish Keyboard and was not Working on LibreOffice and Chrome.
Here the video of my result testing: https://youtu.be/1oz0OlNmw2E
Is not working.
Where I Can set a new Key combination alternative (different to WITCH)?
