Windows 7: Did You Know Facebook Has Built-In Shortcut Keys?

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.
