Using the code I pasted on the bottom, you can emulate these buttons by creating them in your website interface.

To maximise: save the current position with Namespace.outerPositionGet() and size with Namespace.outerSizeGet(), then do Namespace.outerPositionSet({left:0,top:0}) and Namespace.outerSizeSet({width:window.screen.availWidth, height:window.screen.availHeight}).

To restore: just set position and size which were saved when maximising.

var Namespace = (function() {

    var N, W, framePosition, frameChrome, setFramePosition, setFrameChrome;

    N = {};

            top : W.screenTop,

            left : W.screenLeft

        framePosition = {

            left : tmp0.left - W.screenLeft
