right-click event in IE 5.0+

[ovrmyhead]

Is there a right-click mouse event that can be detected in IE 5.0+? I am trying to use Javascript to detect and act on the user right-clicking an object. This is not related to other posts re: text/image theft. Also need to detect and act on a double-click event. Are either or both events valid in IE? Looks like they are in Netscape but my users are on IE. Thanks.
