Peter,

>>ACCESSKEYs Usage of the site could be dramatically speeded up by the inclusion of ACCESSKEYs for the most commonly used links and fields

 

In the version 5.2, ACCESSKEYs are supported in the link dialog, and form controls( textarea, input...).

 

>>Spell Check The spell check function available with the rich text editor was usable with Jaws but was very cumbersome to use.

The NetSpell project is an open source project.  You can download the code of this project and modify it to meer your own requirements.
