Checkpoint: OK

A.2.7 For the authoring tool user interface, provide an undo function. 
[Priority 2]

Rationale: OK

Authors who have difficulty making fine movements may be prone to making 
unintended actions. All authors benefit from the ability to easily 
recover from mistakes.


SUCCESS CRITERIA: SC2 and SC3 clarified; Web-based tool note: Changed to 
properly account for SC2 and SC3.

SC1: Actions that modify content must be either reversible with an undo 
function or include a warning to the author that the action is 
irreversible.

SC2: The author must be able to invoke the undo function multiple times 
in order to undo a series of reversible authoring actions (i.e. two or 
more).

SC3: The author must be able to REVERSE any series of undos.

For Web-Based Interface Components: For client-side text input 
operations, Web-based authoring tools may rely on the undo functions of 
the user agent(s) specified in the conformance profile as long as it 
meets the three success criteria for text input areas. For server-side 
operations, a server-side undo function is still required.




Cheers,
Jan
