Windows Vista has that feature build in that lets you flip through all the open Windows by pressing Alt + Tab. This feature is called Windows Flip in
Windows Vista and is available in all editions of Vista except Home Basic.
Win Flip is a
software for Windows XP that rebuilds this function making it available in XP as well. Instead of accessing the feature by pressing Alt + Tab users press Windows + Tab instead. The only difference from what I can tell is that
videos that are currently playing stop for as long as the user is pressing those keys on the keyboard.
Win Flip uses a surprisingly small amount of
memory. Another nice feature of Win Flip are
mouse gestures which make it possible to access the ‘flipping mode’ by drawing a circle with your mouse. Users can then navigate the open windows with the mouse wheel. A click with the mouse activates the window in front.
