Proposal for SC 4.1.10

From: Jim Allan <jimallan@tsbvi.edu>
Date: Wed, 18 Jun 2008 13:04:05 -0500
To: <w3c-wai-ua@w3.org>
Message-ID: <063e01c8d16d$c0b113d0$42133b70$@edu>

SC 4.1.10 to include override of author supplied bindings that the user
agent can *recognize*. Override of author bindings is not included in the
current SC. We have discussed it several times, but never acted.

<old>
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.

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.

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
