How to remove empty column on the right of the window


I got an annoying empty column on the right of my window.

This happened when I pressed the 3 following keys on my Mac: alt cmd - . Now I am not managing to remove it and did not find any related question. I tried alt cmd +, but unfortunately it did not work.

Anybody can help?


There is a FAQ post for this issue Where did this empty space come from? How do I get rid of it?


Great! I missed that. Hopefully this will also help other people that google this issue in the future.
