Facebook has a small, but useful set of keyboard shortcuts you can use to navigate the social networking site. 

The shortcuts work best with Chrome in Windows and Firefoxon Mac OS X, because they only need one modifier key, plus the shortcut key. Also keep in mind that the number shortcuts must be pressed from the number row; they don't work with the number pad.

Here are the keyboard shortcuts for Facebook:

Windows

Firefox modifier: Shift + Alt + #

Chrome modifier: Alt + #

Mac

Firefox modifier: Control + #

Chrome modifier: Control + Option + #

Safari modifier: Control + Option + #

Shortcuts

1 : home

2 : timeline/profile

3 : friends

4 : messages

5 : notifications

6 : general account settings

7 : privacy settings

8 : Facebook's Facebook page

9 : legal terms

0 : help center

m : new message

? : search

That's it. If you're wondering why Internet Explorer 9 was left out, it's because only the home and timeline shortcuts seem to work. If you want to use IE9 anyway, the modifier is Alt + #, then Enter.

Using the Facebook Shortcuts from Keyboard in your Browser

The shortcuts work generally by pressing the Alt + key. But if you are in Firefox, only pressing the Alt key and then the shortcut key will not work exactly as the Alt key heads up Firefox’s own controls. To use the Facebook shortcut in Firefox, add another key “Shift” before that combination i.e the shortcuts tuns into Shift + Alt + Key for Firefox. For the other browser like Chrome, Opera, Safari, just the “Alt + key” works fine. However, this shortcuts may not be working properly in Internet Explorer.

Composing a new message: Alt + M

You can compose mail from any where in your Facebook profile. Be it you are reading wall posts or any thing else, you can compose messages by pressing the Alt + M (For Firefox Shift + Alt + M).

Facebook Search: Alt + ?
