What’s New in Dataquest v1.63: Hotkeys, Custom Hints, and More

At Dataquest, we want to help you reach your goals. Learning is easier when your environment works with you. We’re excited to announce a few new features that will speed up your learning.

Lesson reference tab

With our new lesson reference tab, you can easily search through all our content. You’ll find it at the top of your in-lesson page, between Q&A and ADMIN.


Let’s say you’re working through our Movies Reviews Guided Project and want to check back on how to use the Jupyter Notebook. Simply click on “MISSION REFERENCE” and type in “jupyter” for relevant results.


Or maybe you want to see if we have content on a topic, without leaving your current lesson.

For example, you’re in our Machine Learning Guided Project on predicting car prices and you want to know what we have on neural networks.


Have you tried out the reference tab? Let us know your thoughts!


Our lessons now have an autocomplete feature — start to type the word you need and it’ll pop up for you. This works for general terms:


And for words specific to lessons:


Custom hints

Troubleshooting — both the thought process and the final result — is an important part of data science. However, we all know how frustrating and intimidating the dreaded error notification is.

Until now, getting an error in your lesson looked something like this:


That error message didn’t give you a lot to work with. Our new custom hints help you build your troubleshooting skills by giving more specific feedback, and suggestions for how to fix what went wrong:



Life is better when you don’t have to use your mouse or trackpad. We’ve updated the list of keyboard shortcuts you use in your lessons:

  • alt + enter: run code
  • alt + t: switch focus to editor
  • alt + r: reset lesson
  • alt + n: next step
  • alt +b: back step

Note that if you’re on a Mac, you should substitute Command for Alt.

Other new features include:

  • When you click on links in the Learn text, they’ll now open in new tabs. No more losing focus because you’re taken out of the lesson, and needing to find your way back.
  • We’ve removed the survey questions from the ends of lessons, for a smoother transfer to your next lesson.

What should we build next?

Feedback from our users is really important to us — we’d love to get your take on what we should build next. If you have an idea, you can e-mail us or get in touch on Twitter!
