In Safari you can switch to the next tab in the current window with Control+Tab. Add the Shift key and you’ll switch to the previous tab. This also works in the Finder if you are in a window with multiple tabs.

Aaron: Can you elaborate on that? The ~ key doesn't do anything for me in switching between tabs in Safari.
