Adding a Bookmark for Twitterrific in Safari (Mac)

How do I add a bookmark to Safari that composes a new tweet in Twitterrific with a link to the current page?

To create a Twitterrific bookmark on Safari on Mac, create a new bookmark, then edit the bookmark's URL by going to Bookmarks -> Show All Bookmarks. Change the URL of the desired bookmark to:

javascript:window.location='twitterrific:///post?message='+escape(window.location)

Then, add it to Safari's Bookmarks Bar section. From there, you'll be able to click on it from any page and have a new tweet open in Twitterrific with the link to that page already filled in.
