About mail-composer's keyborad navigation

Hi,

I find that when we navigation the mail-composer window with keyboard,
the toolbar between "Subject" line and mail body will never get the
focus. I knew someone complained about focusing toolbar, because user
cannot easily enough go to the body. But through the follow
link(http://developer.gnome.org/projects/gup/hig/2.0/input-keyboard.html)
we should make the toolbar focusable, and it is easily to make a patch
for this. What should we fix this?

Regards,
Li
