Instead of Ctrl+Shift+I, I usually use F12 because it works in all 3 browsers Chrome, Firefox, and IE. In IE, Ctrl+Shift+I brings up Favorites/Feeds/History.

Instead of Ctrl+Shift+I, I usually use F12 because it works in all 3 browsers Chrome, Firefox, and IE. In IE, Ctrl+Shift+I brings up Favorites/Feeds/History. However, on Mac OSX, Ctrl+Shift+I makes more sense because the default for F12 is to adjust sound volume up. You have to press Fn+F12 which is more awkward than Ctrl+Shift+I. (Or Cmd+Alt+I in Safari).
