Hello! I don’t know if this has been covered in the courses yet (I’m a day behind. 
), but if you want to quickly comment out a piece of code or just create an empty comment to fill in, you can put your cursor in front of the line you want to comment out and hit “CTRL /”. If you want to be extra precise on what you are commenting out, first highlight the line(s) of code and then hit “CTRL /”.
As Jessica likes to say, developers are lazy. I hope this helps you all become lazier coders!
