Tab Wheel (Ctrl+E) od Milan Spiridonov

Hold Ctrl+E and a round menu appears in the center of your screen, showing each open tab as a slice with its icon and a short title. Just move your mouse over the slice you want—its highlight will brighten—and let go of the key to jump straight to that tab. The menu disappears as soon as you’ve made your choice (or click elsewhere), giving you a fast, visual way to switch tabs without hunting through the tab strip.
