Searches the document body text for a string and selects the first matching string. Optionally, you can specify whether the search should be case-sensitive or should search upward in the document. With the found text selected in Navigator 4, you can then use the document.getSelection( ) method to grab a copy of the found text. You don't, however, have nearly the dynamic content abilities afforded by Internet Explorer 4's TextRange object (for Win32). This method is disconnected in Netscape 6 (it always returns false), but is reconnected in Netscape 7.
