I Agree with that!

There is also a problem of authors using javascript to trap the 
keyboard, which has the same effect.

Not really, this works over one site but not over the all sites - and 
until we have a standard we can't expect a specific key binding 
definition to give us next / prev / menu / sidebars and the like - as 
well as the finer commands of say document processing WebApps, we can't 
expect cross site compatibility. In fact the rel was really good over 
things like sections, pages chapters etc however I only found Amaya 
implemented it last time I looked (admittedly years ago) - however if a 
standard can be reached for page movement and document jumping - surely 
we can do something across sites.
