How can I map a middle click to control click? Just started to use a Mac for my new job and not being able to use the middle button to open links in a new tab is killing me. I know I can press control and do a regular click but it's not the same. I know the Mac knows I'm trying to do something because it beeps at me when I press the middle button on my mouse. Is there any hope?  

Note I tried the trick about setting expose dashboard to - but it didn't work.
Try holding the Command button instead. A Command click is a middle click. Control clicks give you a right click.

What kind of Mac? If you're using a Magic Mouse you can use a program like MagicPrefs to turn a three finger click into a Command click. If you're using the Magic Trackpad or the built-in trackpad on a MacBook/MacBook Pro there is a program called MiddleClick I've used that adds a three finger tap/click ability to map to the Command click.
