Google's Real-Time Search
The people at Google seem to love doing custom scrollbars. RÃ©my Rakic points out that real-time search features another one:
Ben Sargent writes that Aperture has a small "auto-scroll" widget on its scrollbar:
Clicking on this widget scrolls the view without requiring the user to move the mouse, similar to Picasa's scrollbar. zx ads that Evernote on Windows features a similar split scrollbar with a "regular" part and an "auto-scroll" part.
