This script creates a small remote control that lets you move
backwards and forwards through your history, or reload the
current page for this window.<p>

<FONT SIZE=4>
The remote control is created as a separate window; the <FONT COLOR="007777">opener</FONT> property of the
new window points back to this window. The remote needs this in order to access this page's
history. If no parent window is found, the remote will first attempt to
back up and otherwise will close itself.<P>
