Is it possible to disable Ctrl + F of find in page?

Question

I have a puzzle site and its an awful way of cheating. Its okay if only partially, but can it be done?
Something I had in mind was replacing the letters with images, but

you can do it with javascript - this is only pseudocode (written in jQuery) as I'm not certain how to listen for both a ctrl AND an f, but you get the idea:

$(body).keypress(function(e)
{
    if (e.keyCode===17)
    {
        //ctrl has been pressed, listen for subsequent F press (keyCode 70)
        //if next keyCode===70
        return false;
    }
});

Returning false like this will stop the browser doing anything when the keys are pressed, as far as I know. you could also use e.preventDefault(); to try to prevent anything happening if return false; isn't enough.

Hope this helps
