Fun!
From All Forces:
"As a surprise and delight to many web developers, Safari 1.3 (released a few days ago via Software Update) includes WYSIWYG / RichText editing. This feature has been long rumored to be in the upcoming Mac OSX version Tiger. Although there appears to be no documentation, Safari’s developer Dave Hyatt reports that Safari is adapting Microsoft’s contentEditable including execCommand and designMode. So far no web developer has been able to get execCommand to work but contentEditable seems to work just fine. Hopefully there will be some documentation released soon on how to build Javascript interaction so that we can bring some sort of App like interaction.
Safari DEMO:This post is an example of WYSIWYG editing. Got Safari 1.3? Go ahead and DOUBLE CLICK ME (saving not allowed of course). You can try using Command+B or Command+I to make text bold or italic. also, you can drag the image around or even drag and drop an image from the browser or even your Desktop."
