The status bar is the space immediately below the browser display and you can configure it to display text when you hover over a link by using a little javascipt. We'll use the onMouseOver and onMouseOut events, so that when the mouse hovers over the link the text appears, and when it moves away from the link, the status bar is set to blank:
<a href="http//www.codetoad.com" onMouseOver="window.status='Click here to visit one of the best scripting sites around';
return true" onMouseOut="window.status=''; return true">Click here</a>
Keep all the above on one long line to ensure it works properly. Also, don't forget to add the return=true; to the script, otherwise it won't work.
