You can put a transparent fixed-position object using CSS. I suppose you

That's where you get a bit greedy. You'll probably need to involve some
programming to do this.

For all these key and mouse events you'll need callbacks. There are some
demos at JavaScript Source, which provide a good starting point.

I don't think you will be able to do this. You over-estimate the
functionality of browsers. If you managed to do it, it probably would not
be valid and only work in one particular browser.

Go and see WYSIWYG Pro (http://www.wysiwygpro.com/demos/demo1.php) which
does some of the things you are after. It's pure JS, IIRC. Not free
unfortunately.
