The link autocomplete feature is a browser implementation and it is supported only by Internet Explorer. I was unable to create a link by typing www. or http:// and pressing space, enter or copying and pasting it in the content area in other browser except in IE.
If you need this functionality you could attach to the content area events
or to the OnClientPasteHtml event
and implement it yourself and modifying the selected content. Note that you can handle the Paste event only in IE and Firefox, due to browser restrictions.
