Sure. But the tab order has to reflect the worflow all the way through. If  
you have to move a zillion times to get back to add a subject or CC, there  
are serious problems. About 3/4 of my mail uses a Cc, about 10% a Bcc -  
maybe I am a little unusual, but maybe not. And very nearly all of the  
mail I compose directly is to people in my contacts list.

Hmm. The "select from contacts" function is something I only use about 95%  
of the time.

accesskey is designed to provide accelerated access to things. It is badly  
specified, and badly implemented in some browsers, but it is still about  
the best there is. And can be well implemented on the same markup.

How you move around is ultimately a function of the browser, not the page.  
Opera provides several different ways to navigate (by link, or by form  
control, or by header, or in 2-D, or with accesskeys) from the keyboard -  
other browsers do some of this. And phone browsers and the like make the  
picture reasonably complex. Pages that try to specify how navigation works  
fail more often they succeed, whereas pages that provide clear structures  
and waypoints, allowing browsers to provide navigation that is useful, are  
more helpful to the web.
