I was trying to zoom in/out in my notes but found out that “cmd/ctrl then +/-” gets the content, nav bar and side bar to zoom in/out all together and searched the forum and found a closed case with no solution yet.
The solution is: pinch-to-zoom = use 2 fingers on the touchpad and move them away from/ towards each other to zoom in/out.
P.S. I’m currently using the “Minimal” Theme and I don’t know if it is a general feature or only related to the theme.
