Recently upgraded to Lion. I keep accidentially clicking somehow on the mouse and the opened application zooms in. What am I doing and how do I zoom out? Thanks.
It's probably the smart zoom feature of the magic mouse. A Double tap with one finger will zoom.
Double tap until it unzooms. You can turn the feature off in System Preferences > Mouse > Point & Click tab > Smart zoom.
You may have also held down the 'Control' key while using two fingers on the track pad - this zooms as well! To zoom out, just press 'Control' + Use two fingers and pull toward you!
