The little blue triangle, is this done in jquery?

Answer 1

not neccersarly you can you the :focus css selecter to add list-style with desired attribute

example:

a:focus {list-style-type:circle;}

would give a circle to all focused links
the jquery versioned would be something like

$('a').focus(function(){
 $(this).css('list-style','circle');
});
