title: Force Chrome/Firefox into Full Screen?
body: <p>I want to use chrome to display a full-screen html page for a presentation.  You can set chrome to fullscreen mode, but it seems the only way to exit is moving the mouse to the top of the screen and clicking:</p>

  <p>I don't want to disable the ability to exit full-screen, I just want to make it so the only way to exit is via pressing the ESC key, not the mouse position.  That way basically browser "admin" are the only ones who can get out of the presentation.  Is that possible in Firefox or Chrome?  Could I write an extension for this if it's not possible?</p>
