Hello I am on Mac OS X and just got a new keyboard (Microsoft Natural Ergonomic 4000). I am trying to get used to the new keys, but there is one function I really miss and I really can't find: "Expose" (used to be F3 on my previous keyboard). When I go in the system pref > Keyboard, there is no "use all the F... as standard function keys", because well I understand this is not a mac keyboard any more. I tried to check in the "keyboard options" all the different functions, but didn't find an "expose" function (even unticked or hiding somewhere). If there is not that function in the list, does it mean that I can't get it at all with my new keyboard? Or do I need an application like this one? http://www.makeuseof.com/tag/reconfigure-mac-keyboard-geek-power-mac/ Thanks for your help! Smurk.
