How can i design special button so the selected text (into the edit box) will wrap with my own tags, and if there is not selection, just insert  the open tag?
The solution should be compatible with IE and FireFox.
I guess there is internal function for this task, because many standrad buttons doing that (Bold, Italic and etc.), But I can't find any documentation.

I find part of the solution.

For IE:
        editor.setFocus();
        var txt = editor.getSelection().htmlText;
        if (txt != "")
            editor.getSelection().pasteHTML("<tag>"+txt+"</tag>");
        else
            editor.getSelection().pasteHTML("<tag>");

For FireFox:
    var sel = editor.frame.contentWindow.getSelection();
    var txt = sel.getRangeAt(0);
    if (txt != "")
        editor.insertHTML("<tag>"+txt+"</tag>");
    else
        editor.insertHTML("<tag>");

I still have two problems:
1. When selection is empty, the editor insert also the closing tag ("</tag>"). But i need just the opening tag, so the following text will effect from the tag. (My tag is <div...> with some properties).
2. I need way to identify the browser, prefer by functionality, not HTTP Header.

Moshe,   Where did you find this code?  I have been looking for the same thing because I want to do a similar type of operation where I enter my own tags.   Thanks, Nathan
