Free reference tutorial software for windows

XUL Reference is more than a search engine plugin because the extension knows the names of all XPCOM components and interfaces, XUL elements, XBL Elements, events, scriptable objects and common properties/attributes/style-classes of the XUL Element.
If you highlight one of those, then the right click menu will show you what type of object youve selected and open a background tab with the reference page for that object. For instance, if you select the word nsIMsgFolder, then the right click menu will show XUL Reference (XPCOM interface) and clicking on it will open the reference page for nsIMsgFolder in a background tab.

System requirements:
- Firefox: 2.0 - 3.0.*

Enhancements:
- Only technical changes. The extension now no longer loads all the component data from xulplanet every time a window starts. Instead it ships with text files with the names, but they can be updated by going into Tools - XUL Reference and hitting Reload datq
- Changed some error handling, now it wont continually throw up dialog error boxes when something is wrong with xulplanet.com, which was very annoying.

Here is a free ebook on Windows basics. The idea is to deal with practical aspects of using Windows rather than discuss the mundane stuff. Knowing Windows does not mean that you have to know all there is to know about the control panel, device manager, and system restore. In my terminology, if you are able to use Windows for your work and generally know how to do a task better then you should be happy. Leave the control panel and device manager to the geeks and make sure that you know the basics first.
