Zoomed in IN-GAME

Yesterday while i was playing I hit the scroll wheel on my mouse. I know I know....I need a new mouse, but there is not a way to zoom all the way out IN-GAME!!!!! Do you have any idea how hard that was playing on a zoomed in screen!?!?!?!?! Does anyone know how to zoom out without the mouse IN-GAME? No PageUp/PageDown does not work.
