I was spending some time browsing around Facebook today (translation: wasting time), when I noticed that they have some shortcut keys for navigating around the site using the keyboard, so I put together a list for everybody.
Note: for each of these shortcut keys, if you’re using Firefox, you’ll need to use Shift+Alt instead of just Alt, and for Internet Explorer you’ll need to hit the Enter key after the shortcut to trigger it. If you’re using a Mac, you’ll need to use Ctrl+Opt instead of Alt.
New Message: Alt + M
This shortcut key doesn’t seem to work in Internet Explorer at all, but if you’re using Google Chrome or Firefox, it should work fine, though Firefox will use Shift+Alt+M instead.
Search Box: Alt + ?
This shortcut key is the same in Chrome and Internet Explorer, but is Shift+Alt+? in Firefox—it’s really a very useful shortcut, since the search box gets you access to all your friends easily.
Home Page: Alt + 1
This shortcut takes you to your home page—if you’re in Firefox it’s Shift+Alt+1 and IE is Alt+1 and then Enter.
Your Profile: Alt + 2
This shortcut takes you to your profile page—if you’re in Firefox it’s Shift+Alt+2 and IE is Alt+2 and then Enter.
Friend Requests: Alt + 3
This shortcut is somewhat useless unless you’re the most popular person in the world, as it opens up the friend requests page. If you’re in Firefox it’s Shift+Alt+3 and IE is Alt+3 and then Enter.
Messages: Alt + 4
This shortcut opens up the Messages dialog. If you’re in Firefox it’s Shift+Alt+4 and IE is Alt+4 and then Enter.
Notifications: Alt + 5
This shortcut opens up the Notifications dialog. If you’re in Firefox it’s Shift+Alt+5 and IE is Alt+5 and then Enter.
There’s a couple of other shortcut keys, for Alt+6 through 0 on the keyboard, which take you to the settings, privacy, about, terms, and help pages.
