The Universal Edit Button is a green pencil icon in the address bar of a web browser that indicates that a web page on the World Wide Web (most often a wiki) is editable. It is similar to the orange "broadcast" RSS icon (16px) that indicates that there is a web feed available. Clicking the icon opens the edit window. It was invented by a collaborative team of wiki enthusiasts, including Ward Cunningham, Jack Herrick, and many others.
