[Javascript] Text selection property/method?

[Peter Brunone]

List,

	I'm trying to find a way (in IE right now, but may need it for
Mozilla later) to identify and alter the region selected by a mouse drag
(usually identified by highlighting in a color opposite the background).
The selected text will most likely be in a TD.  Any thoughts on what
this mysterious attribute might be called?

Cheers,

Peter Brunone
