Zoom in/out via external keyboard In there a way to get the effect of (zoom out/pinch put)/in with external mouse and or/keyboard?
For games like angry birds or using google earth.
Hold the key Ctrl and &nbsp;↓&nbsp; on your keyboard. Two little opaque circles will appear near your mouse. Hold down the left button of your mouse  and move those little circles. It will zoom in-and-out just using two fingers.
