Accesskey
The accesskey attribute allows page authors to define a shortcut key for interactive page elements (e.g., <a href=”search.htm” accesskey=”s”>Search</a> defines “s” as the accesskey for the search page). Browsers provide varying keyboard shortcut combinations to activate this accesskey. Because of the wide variety of browser and assistive technology shortcut keys, and because there is not a set of keys reserved for use with accesskey, authors can never be sure that their defined accesskey will not conflict with end-user shortcut keys. Because of these difficulties, accesskey should generally be avoided, except in controlled situations where the user systems are well defined, or when users can define their own site accesskeys.
