Are you using Firefox as your browser? Read on.
I am still not fluent in all the commands and other mouse-avoiding shortcuts in Firefox. The Firefox help lists many keyboard shortcuts, and there is more Firefox accessibility information in the MozillaZine knowledge base.

Not using Firefox? Hop over to Firefox and download! It’s my preferred browser, although I do have Internet Explorer and Opera installed for checking the way browsers display a particular site, and for generally staying in touch with the various options out there.
