When using my Apple MacBook I have found that right-clicking without an external mouse can be problematic, as the MacBook only has a single button under the trackpad. However, there is a neat feature in Mac OS X to address this issue. Go to the Apple menu > “System Preferences”. Open the “Keyboard & Mouse” preferences and select the “Trackpad” page. Enable “Place two fingers on trackpad and click button for secondary click”. Now, if you place two fingers on the trackpad and press the button, this will simulate a right-click. Unfortunately, this does not work for Windows XP through Boot Camp. However, there is a free utility called Apple Mouse Utility which will simulate a right-click when holding the Control key at the same time. This utility can be downloaded for free at: www.geocities.com/pronto4u/applemouse.html .
