Is there a shortcut in Mac OS X that resizes two or more open windows automatically so that each window is shown on the screen simultaneously? For example, I want to have a safari window open and a word document open so that one half of the screen is showing safari and the other half is word. I know I can resize them manually but I was wondering if there is a shortcut or a third party utility that resizes any open windows to fit the entire screen? This would be useful, for example, with the new 27 inch iMacs where the wide screen can easily display three (or more) windows side by side utilizing the entire screen area; having them resized automatically would be more productive than having to resize them manually. Any thoughts?
