Windows only: Reader Zarek writes in with an excellent tip for switching between open windows using just the mouse—all it takes is a couple of lines of AutoHotkey code.
The script binds one of your extra mouse buttons combined with the mouse wheel to activate Alt-Tab or Shift-Alt-Tab, depending on which way you are scrolling the mouse. To set this up for yourself, you'll need to create a new AutoHotkey script or paste the following into your existing one to activate your 5th mouse button:
XButton2 & WheelDown::AltTab XButton2 & WheelUp::ShiftAltTab
If you would rather use the 4th button, you can substitute XButton1 in the code where you see XButton2. If your mouse doesn't have any extra buttons, Zarek still has you covered—this solution will activate Alt-Tab using the middle mouse button combined with the scroll wheel—although it's a little more difficult to use.
MButton& WheelDown::AltTab MButton & WheelUp::ShiftAltTab
Where this tip becomes really useful is for readers using Windows 7—once you've activated the Alt-Tab dialog you can simply hold your mouse over any of the preview thumbnails to see the entire window through Aero Peek—very useful when you have too many applications running at once. Thanks, Zarek!
