I sent an earlier version of this with a stray regrets subject line -- 
please ignore the earlier one.

Proposed Link numbers navigation guideline:

This should probably go in or after 4.7.

*4.X.X Direct clickable element access*. The user can directly click any 
clickable element, including links, images, check boxes, fields etc. 
using a short series of keystrokes, e.g. numpad number keys and then 
"Enter", to navigate to that element. A keyboard shortcut is provided to 
hide/show clickable element indicators, e.g. numbers (A).

- Clickable element indicators' keystrokes and hide/show shortcut key(s) 
can be modified by the user (X)  [[Note: not sure if this is needed or 
covered elsewhere]]

- The user can control what the clickable element indicators look like, 
including size, color, style, transparency and location (X).

- The user can control what types of clickable element indicators show 
by group, e.g. links, images, check boxes, fields etc. (X).

- A control is provided to turn on/off dynamic updates of clickable 
element indicators (X).

*Notes: *
- As Web pages have gotten more complicated, there are many situations 
where users who find it difficult or impossible to use the mouse need 
more than sequential navigation. Direct navigation allows such users, 
including speech users, to quickly navigate Web elements.

- Working example : Firefox's mouseless browsing extension  
https://addons.mozilla.org/en- US/firefox/addon/879.

- Clickable element indicators are also a tool for Web developers to 
debug their installations -- you can instantly see the order of links 
and  missing links.
