If I bought something like this. http://www.ebay.com/itm/NEW-TUSCANI...95?pt=Mice&hash=item231c83a7db#ht_6009wt_1347 Could I configure the left side button shown in the photo to do something like open dashboard. I don't see options in mission control or mouse. I finally got a new mini on 23rd with lion. Or does mountain lion have options if I upgrade.
