Just have a look at what i am doing here : http://www.ialma-musica.com/ and press a few time on “TAB” key… see top left… and accesskeys i use in the code. Usefull for blind persons or tetraplegic persons who surf with a trackball at chin by example. Another example here, more visible just over the header : http://www.mouvement-social.be/
I can do it by myself but would be great to include that in the settings of U-Design.
Also, give the possibility to put a text-decoration:underline;
