// @description Finds and marks links to you visually with a tiny favicon of yours. Install and customize what sites should get which icons, and browse the web, getting visual cues for what links go back to you wherever you roam. As a bonus, the first ten links to you on any page (except your own) can be focused by way of access key 1..9 (and 0) -- i e Alt+1 will scroll the first link into view. Visit the script homepage to set it up or reconfigure it. You can also use this hack to change favicons for any page or URL to any other icon you might prefer. An easy way to minimize typing to add a new site to the tool is to run this bookmark on a site you would like to add: javascript:location='http://ecmanaut.blogspot.com/2006/02/mark-my-links-configuration-updates.html'
