[thelist] accessibility issues

[Kevin]

I was thinking of using javascript  to eliminate the dotted
line around my links and images when they gain focus.

onFocus=this.blur();

I have read this creates an accessibility issue for some users.
To work around this issue I thought I could create an object 
for just this group of users so they could kill this javascript 
function by choice.

A check box in the top right corner or some such device.

Can you advise on best practices?

Thank You
Kevin
