Feewhee (Feel the Wheel) is a utility to enhance your mouse wheel with additional functions. With a single turn, you may resize windows or change the transparency.http://www.nattyware.com/help/feewhee.php
Feewhee does not have a user interface. Once started, it runs quietly in background.
Requirement: MouseWheel, Win XP, Vista, 7
How it works:
Put the mouse pointer to a window title bar and roll the mouse wheel to resize the window. Hold down the Shift key when rolling to change the window's transparency.
If you want to disable Feewhee then simply run it again.
License: free for both personal and commercial use.
