If you’ve always wished you could browse through a larger, more diverse range of categories on Netflix, you’re in luck. Thanks to a simple trick that’s actually been around for a while but is now going viral, you can search through tons of different genres with the right codes — everything from British Comedies Based on Books (code 2965) to Critically-Acclaimed Comedies from the 1950s (code 3084). It’s easy — just scroll through this alphabetized list of codes and, in your browser, add the code numbers.

The hack picked up steam again on the Internet this week, and now, of course, you can use the secret codes to satisfy all your niche Netflix needs.
