How to unzoom Chrome-* console
On Mac with a keyboard layout where you cannot do shift++ (since you need shift to do a +, like on the French keyboard layout) you have to "Undock into seperate window", and only then can use Command+0, Command++ or Command+- like you would in a normal window.
I have the same problem when typing ] with AltGr++ key the console interprets as zoom in. (More info on AltGr key here)
To zoom out try pushing AltGr+- or Ctrl+-.
To type } try its Ascii code, which is 125: AltGr+125
