I really don't know much about Ruby, but I would have to say that considering Ruby is a server side language, I would say you can't change things after the page loads, unless you use AJAX (which I assume you can use with Ruby). Nevertheless, AJAX isn't going to do anything to create a cursor... you don't need to refer back to the server at all.
You are going to need to use a client side scripting language (javascript) to create something like this. Post this question in the Javascript forum and you will probably get some great help there.
By the way, do you know any javascript? Where would the user be typing this message? In a text area? A little more info would be helpful.
Again, I don't know much about Ruby, but that is my view.
EDIT: WOOPS! I thought you were taking about Ruby on Rails... disregard this whole post, unless you really were talking about RoR.
