Do you use contextual menus in Mac OS X (Mac OS X 10.5 & 10.4)? If you don't, you might be surprised to know that contextual menus can provide unexpected useful features. For example, in Safari, a contextual menu can be used to easily view or print a web page or to view the source code (HTML code) of any web page. In addition, there are excellent free contextual menu plug-ins that can be added to Mac OS X to let you easily view images, launch applications or organize files.
