The status bar is a lonely, empty place just waiting for you to take advantage
of. You can use it to display a description of the link your mouse is currently
over, show some message etc.
For example, I create a link below that uses this function to a description
of the link
<a href="http://www.google.com" onMouseover="writetostatus('Search the web!')"
I like this
example by Website Abstraction, which gets really creative and
"unscrambles" the message into view.
The key to writing to the status is using the property
remembering to return true if you're adding it to a function.
