The title pretty much explains it , I have a client that would like to be able to surf the net, click the wordpress "press this" button and automatically have the page link added to a custom field. I know this is possible bc when you click the "press this" button it automatically adds the link from the page you were on into the post window as a href link .
A next best solution would be finding a way to edit the output to the editor to remove the extra text wordpress adds to the editor automatically.
