I just found out that OSX can zoom the screen in and out ... I found out because I was leaning on the Control key and trying to scroll with the wheel and and everything started zooming ... cool!
Totally off topic I know, but I've had this machine for 2 1/2 years and didn't know it did that :-)
You're a Mac user?! I didn't know that. There are hundreds of little features in OS X that most people don't know about. You should browse through MacOSXHints.com (http://www.macosxhints.com/) to find more. Also, if you've got a Mac (check) and you love Commodore computers (check) then you owe it to yourself to check out Think Commodore (http://www.thinkcommodore.com). :)
