Mac Attack

Got to work this morning, only to find that the Mac Mouse of much mightiness has gone AWOL. As I haven't been born with a mouse in my hand, I sat and tried to use the keyboard. Not a good idea. For starters, choosing a desktop icon and hitting "Enter" lets you modify the shortcuts name. This is probably what Apple refer to as intuitive interface.
About 15 minutes later, I managed to delete two icons and open the Script Editor (Whatever that is). Eventually I googled this page. Action + O ('O'pen?) does the trick. More interesting is the "close window" command: Command + W (close 'W'indow?). I've no idea why they have to use different keys than the ones used at Windows or GNU/Linux.
