nHTMLn.DLL comes with a nice html documentation. Here's an example that opens yahoo.com and refreshes the page every 30 seconds: //window @@ | dll $nhtmln attach $window(@@).hwnd | dll $nhtmln navigate w[/i]ww.yahoo.com | .timerREFRESH 0 30 dll $nhtmln refresh

($nhtmln is a custom identifier that returns the path to nHTMLn.dll. I recommend you to use it this way.)
