How do I go back and forward in Chrome using a Magic Mouse in Lion?
IDK about the Magic Mouse but three finger swiping works on the Magic Trackpad
By default swiping between pages is set to two fingers in Lion. However chrome doesn't currently recognize two finger swiping but it does recognize three finger swiping.
To enable three finger back and forward swiping simply go to the Magic Trackpad preferences and set &quot;Swipe between Pages&quot; to &quot;Swipe left or right with three fingers&quot;.
Update
Google has updated Chrome to work with a one finger swipe for the Magic Mouse and a two finger swipe for the Magic Trackpad in Lion.
