As per my action item from today's call, here's what I see as the main 
pieces. I've also split them up since they may lend themselves to 
different priorities:

NOTE: Keyboard shortcut probably needs a definition that excludes 
keyboard controls for sequential navigation (arrow keys, ENTER, TAB, etc.)

(1) Visual Keyboard Shortcut Indicator ("Chrome"): Provide a user 
setting in which currently visible user interface "chrome" components 
visually indicated their keyboard shortcuts, IF ANY (e.g., with 
accesskey letters underlined).

(2) Ensure Keyboard Shortcuts: Any user interface "chrome" component 
that can receive *user interface focus* using the keyboard has a 
keyboard shortcut, unless the *operating environment* prevents this.

(3) Visual Keyboard Shortcut Indicator (Content Display): Provide a user 
setting in which any *recognized* keyboard shortcuts for currently 
visible content are visually indicated (e.g., with overlays).

(4) Programmatically Available Keyboard Shortcuts ("Chrome" and Content 
Display): If a keyboard shortcut exists for a component, then it is 
available programmatically.

(5) Document Keyboard Shortcuts ("Chrome"): Any *warping keyboard 
shortcuts* (shortcuts to destinations requiring multiple mouse clicks) 
are listed in the documentation. Note: Separate lists are permitted for 
the "base" user agent, each extension and each plug-in.

(6) Content Focus Keyboard Commands (Content Display): Users may request 
a list of all keyboard commands that are currently available and are 
"recognized" to move the content focus.
