Hi Adam,
Thanks for your answer.

This is basically what I did. I needed to get current selection as well, so here is the trick :

//Function to get current selection in IE (6 & 7) and Firefox (2.0)
function getSel() {
    var editor = document.getElementById('CE_Editor1_ID');
    var txt = editor.GetSelection();
     if(txt == '[object]') {
       //In IE we need this trick
        txt = txt.createRange().text;
     }
    return txt;
}
