Viewing the photos sent back from NASA’s Mars Curiosity mobile science laboratory has been exciting over the last week, but here’s one with a twist… and a roll.

Option-Click in Scroll Bars for Jump Scrolling
In Mac OS X in general, and thus in most native Mac OS X applications, hold down the Option key and click anywhere in a window's scroll bar to jump to that spot (rather than scrolling one screen).
