the last version didnt answer the question, so here it is:
(this code snippet is taken from php-fusion and it answers
the question -> !selected text!)
*/
function addText(elname, wrap1, wrap2) {
	if (document.selection) { // for IE 
		var str = document.selection.createRange().text;
		document.forms['inputform'].elements[elname].focus();
		var sel = document.selection.createRange();
		sel.text = wrap1 + str + wrap2;
		return;
	} else if ((typeof
document.forms['inputform'].elements[elname].selectionStart) !=
'undefined') { // for Mozilla
		var txtarea = document.forms['inputform'].elements[elname];
		var selLength = txtarea.textLength;
		var selStart = txtarea.selectionStart;
		var selEnd = txtarea.selectionEnd;
		var oldScrollTop = txtarea.scrollTop;
		//if (selEnd == 1 || selEnd == 2)
		//selEnd = selLength;
		var s1 = (txtarea.value).substring(0,selStart);
		var s2 = (txtarea.value).substring(selStart, selEnd)
		var s3 = (txtarea.value).substring(selEnd, selLength);
		txtarea.value = s1 + wrap1 + s2 + wrap2 + s3;
		txtarea.selectionStart = s1.length;
		txtarea.selectionEnd = s1.length + s2.length + wrap1.length +
wrap2.length;
		txtarea.scrollTop = oldScrollTop;
		txtarea.focus();
		return;
	} else {
		insertText(elname, wrap1 + wrap2);
	}

Ok. I admit it. This code doesnt actually do the required
but you should be able to understand the principle.
Have fun with the code as I had :)
