Adding accessiblity to Navigation with Access Keys

There is a great article by Stuart Robertson in A List Apart this week on the use of Access Keys titled, Unlocking Hidden Navigation. What are access-keys you ask? Access Keys (an introduced W3C standard) allows for the navigation of online content without the use of a mouse by assigning a combination of keys (eg. alt+1) to nav items. Adding access-keys to navigation also enables people with limited mobility to access navigation by using the keyboard, voice or via a screen reader. There are also great discussions in the article forum thread.
