That's why I said the browser would be allowed to require a prefix
before the author-specified accelerator. The problem is that the
browser has no way, in general, to generate meaningful mnemonics for the
document-supplied controls. So it's useful to let the author indicate
mnemonics that make sense for the document and allow the browser to do
something sensible with those mnemonics. So, I *do* think it's an issue
of document structure and not simply of style. The document author is
explicitly specifying the structure of a set of controls supporting the
document; this is inherently an author-side activity.
For example, if the browser
provided a menu "Document Controls" which it used as the root for a set
of cascading menus corresponding to the paths in the document-specified
controls, and if the browser used escape-D as a prefix for controls
located in the document menu, then if the author provided a Search
control with the mnemonic "S", the browser could respond to escape-D-s
by going to that control.
Another browser might put the document controls in a floating pallette,
using the mnemonics to label little buttons.
A test-based browser might use the mnemonics to identify entries in a
textual list of options.
The browser is *not* required to provide the mnemonics, it is simply
informed that they are a set of short identifiers for the
document-supplied controls that made mnemonic sense to the author.
