The more keyboard shortcuts you learn to use, the easier you’ll be able to navigate most applications. Several little-known keystrokes work particularly well on Facebook. Practice using them and you can be more efficient while wasting your time on the site.
Here are a few of the shortcuts, courtesy of The Next Web:
* When scrolling through photos, just push “L” to like. Press it again to unlike it.
* Press “1″ on your keypad to return to the home screen.
* Hit “5″ to bring up your notifications.
