Here are some techniques for checkpoints 2.1 through 2.6.

Technique 2.1

Use the techniques in section 1.1 as they pertain to a keyboard input device.

Technique 2.2

- Documentation for default keyboard commands should be provided in electronic
format for direct access as defined in Technique 1.5. Keyboard
commands should include but not be limited to shortcuts, accelerators, tab keys,
and element activation keys.

Technique 2.3

- Documentation for the current keyboard commands should be provided in
electronic format for direct access as defined in Technique 1.5. Keyboard
commands could change as a result of the addition of navigation bar tasks,
addition of document defined accesskeys, and/or changing the default keyboard
actions through a keyboard mapping facility. When constructing a keyboard
mapping facility it is important to provide associated descriptions for the task
being mapped.

Technique 2.4

A mechanism for allowing the user to configure the mapping of key strokes to
user agent functionalities is to implement a keyboard mapping facility.

Technique 2.5

A mechanism to allow the user to turn on and off author-specified keyboard
configurations is to add a checkbox in the keyboard mapping dialog to that would
toggle the support for author-specified keyboard configurations. An example of
author-specified keyboard configurations is the use of the HTML 4.0 accesskeys.

Technique 2.6

Platform conventions used to indicate which keys activate which user agent
functionalities are using the shortcut key (mnemonics), and keyboard
accelerators defined in standard controls. These are visually rendered using an
underscore under a character in a menu item or button corresponding to the
shortcut key activated with an ALT+character.  For  menu accelerators the text
in the menu item is often followed by a CNTRL+function key. These are
conventions used by the Sun Java Foundations Classes and Microsoft Foundations
Classes for Windows.


Provide information to the user about the current keyboard configuration
 Provide documentation on default keyboard commands and include with user agent
documentation and/or user help system
