Last year, Facebook introduced a "Snooze" option that allows you to mute a friend for 30 days on your News Feed. Now it's extending that feature to keywords. According to Facebook, "Keyword Snooze" allows you to automatically hide any post that features a keyword you don't want to see for 30 days. You can access the feature the same way you find regular Snooze options -- through the post's upper right-hand menu in News Feed. It's currently being tested with a small percentage of people in the US and will roll out more broadly later this year.
