Facebook doesn't have a large collection of keyboard shortcuts and many of them require browser-specific modifiers. Still, if you spend a lot of time in Facebook, using the keyboard shortcuts can be time-savers. The News Feed navigation shortcuts in particular, are convenient and easy to remember because they work the same in every Web browser (no modifier required).

To scroll through your News Feed, just use j to scroll down and k to scroll up.

to scroll down and to scroll up. To comment on the selected story from your News Feed, use c .

. To like or unlike a selected story, use l.

Keep in mind that when you select a story, the left border of the story's location will darken to let you know where you are.
