Also, you can just hold down the control key when you click, whichever of these suggestions works best for you. I tend to use the 2 finger method when I don't have a multi-button mouse attached.
I really like the two finger tap as well... unfortunately... I switch back and forth between Macs and PCs pretty regularly. Everytime I'm on a PC, I start out trying to do the right (secondary) click with the two finger tap. It becomes very intuitive.
Double tap for right click sounds useful but I can't find it. System Preferences > Keyboard and Mouse yields a window with three tabs: Keyboard, Bluetooth, and Keyboard Shortcuts. No Mouse. What to do?
I found that if you go into the control panal and then click on Boot Camp which should be an icon in your control panel if you are running windows in Boot Camp. Then in the Boot Camp options there are options to apply click on tap and second click on double tap. There are also options for using the apple remote and the F1 F2 F3 keys. Just go along the tabs across the top of the BootCamp options window.
I hope this helps
