If you are referring to the zoom in or out, follow these steps:
1)If you have a mouse with a wheel, hold down the CTRL key, and then scroll the wheel to zoom in or out.
2) If you click the Change Zoom Level button , it will cycle through 100%, 125%, and 150%, giving you a quick enlargement of the webpage.
