Checkpoint details
Comments:
- Seems like accesskey not implemented. Lots of UI
features have keyboard access.
Provision details
-
Ensure that the user can operate through keyboard input alone any user agent functionality available through the user interface.
Provision details
-
Allow the user to activate, through keyboard input alone, all event handlers that are explicitly associated with the element designated by the content focus.
-
In order to satisfy provision one of this checkpoint, the user must be able to activate as a group all event handlers of the same input device event type.
Provision details
-
Ensure that every message (e.g., prompt, alert, notification, etc.) that is a non-text element and is part of the user agent user interface has a text equivalent.
Provision details
-
Render content according to format specification (e.g., for a markup language or style sheet language).
Provision details
-
For content authored in text formats, provide a view of the text source. For the purposes of this checkpoint, a text format is any media object given an Internet media type of "text" (e.g., "text/plain", "text/html", or "text/*") as defined in RFC 2046 [RFC2046], section 4.1.
Provision details
-
Allow configuration to provide access to each piece of unrendered conditional content "C".
-
When a specification does not explain how to provide access to this content, do so as follows: If C is a summary, title, alternative, description, or expansion of another piece of content D, provide access through at least one of the following mechanisms: (1a) render C in place of D; (2a) render C in addition to D; (3a) provide access to C by allowing the user to query D. In this case, the user agent must also alert the user, on a per-element basis, to the existence of C (so that the user knows to query D); (4a) allow the user to follow a link to C from the context of D. Otherwise, provide access to C through at least one of the following mechanisms: (1b) render a placeholder for C, and allow the user to view the original author-supplied content associated with each placeholder; (2b) provide access to C by query (e.g., allow the user to query an element for its attributes). In this case, the user agent must also alert the user, on a per-element basis, to the existence of C; (3b) allow the user to follow a link in context to C.
Provision details
-
For rendered content where user input is only possible within a finite time interval controlled by the user agent, allow configuration to provide a view where user interaction is time-independent.

For graphical user interfaces, as part of satisfying provision one of this checkpoint, allow at least one configuration where the highlight mechanisms for the four classes of information: differ from each other, and do not rely on rendered text foreground and background colors alone.
-
For graphical user interfaces, as part of satisfying provision one of this checkpoint, if a highlight mechanism involves text size, font family, rendered text foreground and background colors, or text decorations, offer at least the following range of values: for text size, the range required by provision three of checkpoint 4.1. for font family, the range required by provision three of checkpoint 4.2. for text foreground and background colors and decorations, the range offered by the conventional utility available in the operating environment for users to choose rendered text colors or decorations (e.g., the standard font and color dialog box resources supported by the operating system).
