Duel Navigation:

Please could all members voice their opinions:

Is it too restrictive to insist on there being only one element in  
focus at any time? even in a gaming situation?

Does anyone have experience of using dual controls to navigate(1)?
Where one set of controls is linear, the other planar?

Has someone has already come across something similar, though not  
necessarily identical,
and perhaps already analysed and resolved the issues likely to arise?

thanks again

(1) keyboard tab and mouse offer alternative methods to navigate a  
web page or application.
Assuming that it is device independent and accessible.

However it hasn't been satisfactorily described what should happen  
when both are in use:
what will the window.status show as the destination URL? (2)

If there is to be a single focus, should the tab 'jump' to the  
current mouse event locus? and vice versa
Would changing mouse location might be more contentious?

If one had separate controls on a steering column in a car, this  
would be expected,
Even with a space-warp drive the expectation might be that jumping on  
a bicycle doesn't drop one back where one last used it....

This relates to a bug I am proposing to the CDFWG http://www.w3.org/ 
2004/CDF/ :

window.status & duel focus one example of a really fundamental  

Should there be only one element allowed to be in focus?

For instance if one tabs through a document and at the same time  
mouseover a
It will be normal that a click will deliver me to one URL, whereas an  
will deliver me to another.

Device independence suggests that maybe this isn't such a good idea.
consider, what will the window.status show as the destination URL?
It can only be 'right' 50% of the time.

Unless one implements a 'last use' policy with a single focus.
