This is what I sent to Jim and Kelly. I'm not thrilled with the 
testability of "most commonly used functions" (maybe we could define the 
term and use examples like functions in the highest level button bars 
that are on by default). Anyhow, here it is:

Direct keyboard commands are provided to activate the following classes
of functions (contingent on direct keyboard commands being available in
the *operating environment*):
(a) most commonly used functions (e.g., address bar, "back" button, etc.)
(b) display-related functions (e.g., increase/decrease text size,
volume, etc.)

Note: Change "operating environment" Def'n to add device restrictions:

operating environment
The environment that governs the user agent's operation, including both
software (e.g., operating system, programming language environments such
as Java) and hardware (e.g., mobile devices with a limited number of
buttons).

Cheers,
Jan
