As I'm just one of many forums hosted here I don't think that there is. But holding the 'Control' key and rotating the mouse wheel away from you should 'zoom in' on the page. Wheel back to reduce it. At least with Firefox that's how it works. I've become so used to having to do this for all the different pages I visit I don't give it a thought now. The zoom menu is normally hidden under the 'View' menu.
