I am new to Linux and KDE. I have recently been a Gnome user during my short experience with Linux, but am checking out KDE now and quite like it.

I'm having some difficulty, however, figuring out how to attach the so-called Exposé effect (shows all open windows) to activate with the press of the mouse wheel. I have found a setting where I can attach this to a keyboard combination, but I'm used to using the mouse wheel button to activate it on OSX and Gnome. Is there any way to accomplish this in KDE?

Thank you in advance for any advice you can give.
