AT shortcut keys override HTML access keys. If an AT user encounters ALT+S,
and they already have an ALT+S defined as part of the AT shortcut keys, the
AT shortcut key will take precedence. Given that AT shortcuts override HTML
accesskeys, adding shortcut keys, in my opinion, brings no benefit to AT
users.

I was specifically referring to accesskeys (as HTML attribute)

By using the 'focus' event it is possible to expose shortcuts, etc to
keyboard users, while keeping them hidden from the conventional visual
display.

Smart design can will ensure accesskeys are exposed to users when
applicable. Ignoring the benefits accesskeys can bring to a large segment
of the user population (such as older people who may have problems clicking
a mouse, or people with RSI) who do not have AT installed, is like throwing
out the baby with the bathwater. Careful consideration of how the accesskey
attribute is used, can enhance the experience for a huge group of people
without causing interference to others.
