There’s a well known feature/trick that allows you to right-click using just your trackpad in OS X. What’s slightly lesser known is that the same trick can be extended to XP and Vista running via BootCamp, or guest Operating Systems running in Parallels or VMware Fusion.

1. For Operating Systems running on your Mac via BootCamp, all you have to do is place two fingers on the trackpad, and click the button. That will bring up the right-click menu.
2. For guest Operating Systems running in Parallels or VMware Fusion, open the OS X System Preferences and select Keyboard & Mouse. Place a check in the box labeled For secondary clicks, place two fingers on the trackpad then click the button.



3. Now when you’re running a guest OS in VMware Fusion, you can right-click by placing two fingers on the trackpad and clicking the button once.



4. Same thing for Operating Systems running in Parallels.
