Actual Size, Fit in Window

In Illustrator, there is often more than one way to do things, and zooming in and out is no different. You can use keyboard shortcuts to change the view to Actual Size (Command-1 [PC: Control-1]) and Fit in Window (Command-Zero [PC: Control-Zero]), and you can also change to these views using the Toolbox. Double-click on the Zoom tool to change to Actual Size view, double-click on the Hand tool to change to Fit in Window.
