Using freecodecamp for months and never saw that. I pressed shift/maiusc or ctrl(shift most probably) combined with a button on the right of the keyboard. It opened me an external window that doesn’t make me continue due to an “inception” of windows, it’s like it mirrored the screen on the right.

Yes @gabbuz04.parkour,
Those kind of surprising things happen while you are doing something!
So if you are strugling with it becouse of the double tab it is not working for you you can maybe try to Reset that browser!
Good luck
You are missing an “s” at the end. It should be locations.
location is a browser property on the window object. If you open your browser console and put location = "https://google.com" it will navigate to that site.
