Expanding on "not possible"...

The "Same origin policies" apply: your only way of communicating with the contents of iframes that come from another [domain|subdomain|protocol|port] is through the postMessage API, which of course requires the other part (the document inside the iframe) to listen to your messages. This means that unless you're a google employee with access to the search frontend, this won't be possible.

If you work at google and want to press a button forcefully, I recommend standing with your foot on your mouse: your weight will help push it with more strength.
