If you'd like to code along in the browser with one of the lessons that isn't a lab, you can use the IDE In Browser Sandbox. The IDE Sandbox is very similar to the IDE In Browser. The main difference is that in the Sandbox, your code only saves for the session you're currently in. Once you leave the page or refresh the page, the code you wrote in the Sandbox will be gone. 

So, this the Sandbox is a perfect place to be if you want to try some code out as you read through a lesson that's not a lab, but if you're taking notes, or writing code you want to save, you'll want to keep those elsewhere.
