On my IMac at home I have the Magic mouse and trackpad, on a web site I can hold two fingers side by side and spread them apart making the wed page fill the screen, I just picked up my Fire Dept. Chief a new IMac and didn't get a trackpad (he's tight) and I can not for the life of me figure out how to make the page fill the screen and I don't want to use the function that does the whole screen zoom either. Please help me as this is probable simple
