Focus the taskbar and switch windows with the arrow keys in Windows 7
The taskbar seems like it was meant to be used with the mouse only; it's a very visual thing, especially in Windows 7. But it turns out there's a way to "switch" to the taskbar and then work with it using the keyboard only! Hit Win+T to focus the taskbar, and then use the arrow keys to cycle between the icons. Whenever the focus switches to an application that's currently running, its Aero Peek pane will show up. To start an application that isn't running, press Enter.
What's nice about this system is that it takes your taskbar's orientations into account: for a vertical taskbar, Up/Down will switch windows, while Left/Right would activate the Aero Peek thumbnail pane; for a horizontal one, Left/Right would switch windows and Up/Down would activate the thumbnail pane.
