Today I came across a wonderful collection of helpful hints for Google related tools. Take a look at what they call Google Crib sheets. Lots of great resources for topics including Google Apps for Education, Blogger, Books, Calendar, Docs, Earth, Gmail, Groups, Maps, Mobile, News, Picasa, Reader, Scripts, Search, Sites, Sketch Up, Translate, and Voice.
Each doc includes an explanation of the tool, a why you use it, instructional ideas, and links to examples.
Great ways to quickly learn what a Google tool has to offer!
