Here is a cool little trick for resizing your icons in Vista. Similar to how some online maps, such as Google Maps, now allow you to zoom in and out with the simple scroll of a mouse wheel,
you can now resize your file icons from small to huge by pressing the
Ctrl key and scrolling the mouse wheel. Since different media types
are typically viewed in different ways, resizing your icons with the
mouse wheel can cut down on the time it takes to view large thumbnails
of your photos or small icons for data files.
