More rationales gor GL1

Following is a start on proposed text for Guideline 1 checkpoints as per 
my action item from May 2.  Thoughts?

--------------------------------------------

A.?.2 Provide author profile functionality. [Priority ?]

Rationale: When a large number of configuration settings are available, 
authors working on shared systems benefit from the ability to save and 
later reload a profile that contains all of these settings.

SC1: The ability to save and reload a set of configuration settings must 
be provided for all configuration settings related to visual or auditory 
output and keyboard operability.

--------------------------------------------

A.?.4 Ensure previews emulate accessible rendering features of browsers 
[Priority ?]

Rationale: The workflow of many authoring tools includes periodically 
checking a preview of how content will appear in a browser. When this 
functionality is not provided by an external browser, the authoring tool 
should ensure the same level of accessibility to the content as a 
browser would provide.

--------------------------------------------

A.1.7 Ensure that all user interface controls have clearly associated 
labels. [Priority ?]

Rationale: When there is a clearly associated label, the purpose and 
operation of a control is more clear.

--------------------------------------------

A.2.3 Allow authors to control time limits on their reading or 
interaction. [Priority ?]

Rationale: Authors who have difficulty typing, operating the mouse, or 
processing information can be prevented from using systems with short 
time limits.

Note: Some time limits may be imposed by external systems. This 
checkpoint only applies to time limits within the control of the 
authoring tool.

--------------------------------------------

A.2.7 Provide an undo function.. [Priority ?]

Rationale: Authors who have difficulty making fine movements may be 
prone to making unintended actions.

--------------------------------------------

A.2.8 Separate selection from activation. [Priority ?]

Rationale: Successful keyboard navigation requires that the author be 
able to move the focus through the interface controls until the target 
control is reached. This process is prevented when controls other than 
the target automatically activate.

--------------------------------------------

A.3.2 Organize content consistently from "page to page" and make 
interactive components behave in predictable ways.@@"Maintain 
consistency within the authoring tool user interface."@@ [Priority ?]

Rationale: Authors who may become disoriented easily will have less 
difficulty when consistent and predictable responses to author actions 
are provided.

--------------------------------------------

A.4.1 Support interoperability with assistive technologies. [Priority 1].

Rationale: Authors who use assistive technologies (e.g. screen readers, 
etc.) may not be able to use authoring tools that are not sufficiently 
interoperable with their assistive technology.
