jQuery UI Dialog : Modal Form

jQuery UI Dialog : Modal Form


With ref to: http://www.jqueryui.com/demos/dialog/#modal-form
Can someone please let me know what I would need to modify in order
for the ui-state-hover to be actived when the 'Create new user' button
is onFocus.
I am not great with JS - so if you can provide tested code/snippets it
would be greatly appreciated
In fact wherever there is a 'hover' element/visual change - I would
like there to be the equivelent onFocus.
I love jQuery UI plugins, but sometimes there are basic accessibility
issues - onFocus visual representation is the most overlooked - users
that have restricted movement and can only use tabbing to move through
links can get lost in the links when there is no 'focus' state equal
to that of the 'hover' state.
Many thanks in advance
