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

4. Direct keyboard commands can be used to activate the following
important functions (list)
(a) move content focus to the next/previous enabled element in document
(b) activate the link designated by the content focus
(c) open search function, search again
(d) increase/decrease the scale of rendered text
(e) increase/decrease global volume
(f) stop/pause/resume and navigate efficiently audio and
animations,including video and animated images
(g) next/previous history state (i.e., forward/back)
(h) enter a URI for a new resource
(i) add a URI to favorites (i.e., bookmarked resources)
(j) view favorites
(k) reload a resource
(l) interrupt a request to load or reload a resource
(m) navigate forward and backward through rendered content by
approximately the height of the viewport
(n) for user agents that render content in lines of (at least) text:
move the point of regard to the next and previous line
