jquery emulate key press "ctrl and +"
<p>I know the technique for zoom the page using the shift of CSS.</p>

<p>I want to make a button for emulate the user that press <kbd>CTRL</kbd> and <kbd>+</kbd> in same time.</p>

<p>In firefox if I press <kbd>CTRL</kbd> and <kbd>+</kbd> in the same time the page zooms. I want to write a function that I call and I emulate the press of <kbd>CTRL</kbd> and <kbd>+</kbd></p>

<p>How can I do that?</p>
