RE: Proposal for SC 4.1.10

Dean,
Good point. Always a problem when trying to make a SC do too much.
Perhaps splitting it would be better.

<old Jim proposal>4.1.10 User Override any Binding: The user can override
any binding that is part of the user agent default input configuration
except for conventional bindings for the operating environment (e.g., for
access to help). The user can override any author supplied content
keybinding (i.e. access key) that the user agent can *recognize*. The
keyboard combinations offered for rebinding include single key and key plus
modifier keys if these are available in the operating environment.
</old Jim proposal>

Splitting them reverts 4.1.10 to its original state before I added the new
line about user override.

<original>4.1.10 User Override any Binding: The user can override any
binding that is part of the user agent default input configuration except
for conventional bindings for the operating environment (e.g., for access to
help). The keyboard combinations offered for rebinding include single key
and key plus modifier keys if these are available in the operating
environment.
</original>

<new>
The user can override any author supplied content keybinding (i.e. access
key) that the user agent can *recognize*.
</new>

Note: *recognize* is a defined term. With AJAX and other scripting authors
can create keybindings of which the UA is unaware and has no ability to
allow the user to reassign keybindings. See SC 4.1.5
