[jQuery] toggle content link (beginner)

[tlob]

Hi there

I have something like

[code]
function popUp(url) {
                                
newwindow=window.open(url,'soundbumbam','height=50,width=150');
                                window.focus();
                                return false;
}

<div id="sound">
<a href="javascript:popUp('sound.html')" id="soundme">sound on</a>
</div>
[/code]

I like to toggle on click the content "sound on/sound off.
also the popup should close or open corresponding to his state opend/
closed

What function would you take to toggle the content? append?
How can I combine it with toggle()?

thx for helping out a newbie!
