Keypress anywhere to text field?
<p>I'm wanting to mimic the functionality in the new Myspace. What happens is you can simply start typing and the UI changes to a "search". The characters entered are now within a large text field with auto complete showing results.</p>

<p>How do I detect a keypress anywhere on the page, not within a specific text field? 
How do I then show the text and/or focus on the text field with the text being entered?</p>
