There is still no solution to this?

I fixed it. Now I can use ctrl+w, ctrl+n, ctrl+t, ctrl+l etc. on my page even there is only Flash visible and nothing else. The method puts the focus out of Flash each time the Flash is clicked. So it's not any more possible to navigate the Flash by keyboard. That's the downside of this solution (or added bonus, actually the keyboard navigation can be also only annoying in many cases). There was also a solution forwarding only specific keypresses but I didn't try that (http://stackoverflow.com/questions/254111/flash-steals-browser-focus).

This is my solution, tested on IE, Firefox and Chrome:

add 'wmode','opaque' to the Flash AC_FL_RunContent part in the html

add <param name="wmode" value="opaque" /> to the Flash object part in the html

this goes anywhere in the html:

<script type="text/javascript" language="javascript">
    function changeFocus(){
        var elem = document.getElementById("anyIdThatExistsInHtml");
        elem.tabIndex = 0;
        elem.focus();
        elem.blur();
    }
</script>

and the AS3 script needs this bit (or customize to your purposes):

    import flash.external.ExternalInterface;

        ..

        function onMouseClick(ev:Event):void
        {
                ExternalInterface.call("changeFocus");
        }
        stage.addEventListener(MouseEvent.CLICK, onMouseClick);

I fixed the text field problem, or made a workaround. This new solution is needed if there are text fields where you could click but you don't want to loose ctrl+w, ctrl+n etc. capability. The main downsides to this workaround are:

- Firefox: you have to copy your text quickly after selection if you want to do that (selection vanishes soon)

- Firefox: if you have a web link on your static text and you click it, you can't hold mouse button for 700ms+

- all other browsers: Right click + Copy does work but ctrl+c you have to press quickly, otherwise it doesn't copy

- on Safari, the keyboard capability breaks if you click multiple times on a text box (probably not so difficult to fix)

This is the new javascript (same as before except some new lines, rememeber the wmode=opaque thing!):

<script type="text/javascript" language="javascript">
    function changeFocusAgain(){
        var elem = document.getElementById("anyIdThatExistsInHtml");
        elem.tabIndex = 0;
        elem.focus();
        elem.blur();
    }
    function changeFocus(){
        var elem = document.getElementById("anyIdThatExistsInHtml");
        elem.tabIndex = 0;
        elem.focus();
        elem.blur();
        setTimeout("changeFocusAgain()",700);
    }
</script>

..and the AS3:

    import flash.external.ExternalInterface;

        ..

        function onMouseClick(ev:Event):void
        {
                ExternalInterface.call("changeFocus");
        }
        stage.addEventListener(FocusEvent.MOUSE_FOCUS_CHANGE, onMouseClick);
        stage.addEventListener(MouseEvent.CLICK, onMouseClick);
