Hi, I'm really new to Mac, and I'm hoping I'm just missing something easy here. What I want to do is be able to minimize all the windows on my screen with one button. To make it clearer, say i needed to get a file off my desktop, instead of minimizing or moving all the windows around to get there, I just hit one key and they all minimize. I have the new wireless keyboard, and the only two unused "F" keys are F5 and F6, which do nothing. Another note, my girlfriend has a macbook and she says F9 does the trick. F9 skips a track in itunes on my iMac.
