Re: Question about SC 2.4.3 Focus Order

 I think the key is the term 'advancing', which suggests 'forward' (as
opposed to backward) movement.

Logic (to me) suggests that *IF* the 'advancing' tab order (1, 2, 3, 4, 5)
is logical and appropriate when moving forward, it would stand that going
in the opposite direction would expect a tab order in reverse (5, 4, 3, 2,
1). Since the user is already consciously "reverse-advancing" (retreating?)
using shift+tab, I would suspect their expectation would be that the
visible tab focus proceeds in *THAT* (reversed) order.
