DISQUS

Damn, I wanted to add that you can do it by creating a little apple script like:

tell application "ScreenSaverEngine"
activate
end tell

1) Save that in an applescript somewhere.
2) Then open the Quicksilver preferences and go to Triggers.
3) Add a new trigger by clicking on the plus Icon
4) Type in the name of your script and select it (you might need to rerun your indexing for quicksilver so it gets the script)
5) You can now add any keyboard shortcut you like.

(Taken from the comments in http://www.macosxhints.com/article.php?story=20...)

You can also use quicksilver to lock your screen without clicking.

How do you actually get the filesystem support? I can only see the sshfs command and nothing else :(
