If you have the habit of using the fancy-pants Chrome Beta for access to the latest features to the browser of your choice, try this hand gesture to zoom out. In any page on the desktop, double-tap anywhere on the second tap and hold your finger on the screen. Then, slide your finger up and down to zoom quickly and easily. It works the same way as the "pinch to zoom" function does, but with one finger.
