Checkpoint text: OK

A.2.3 For the authoring tool user interface, allow authors to control 
time limits. [Priority 1]

Rationale: OK

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

Note: OK

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

Success Criteria: REWORD AS OPTIONS FOR ONE SC -using wcag language, 
choose a better example of external time constraints

SC1: All user interface time limits must be author configurable unless 
they are controlled by time-sensitive external processes (e.g. time-outs 
of systems outside of the authoring tool).

SC2: If a time limit is under the control of the authoring tool, it must 
not be less than 20 seconds and must be extendible with a single input 
action.

TO:

SC1: If a time limit is not controlled by time-sensitive external 
constraints (e.g. actions of another author in a collaborative authoring 
system, external connection time-outs, etc.), then the time limit must 
meet at least one of the following:
- the author is able to deactivate the time limit,
- the author is able to adjust the time limit over a wide range that is 
at least ten times the length of the default setting, or
- the author is warned before time expires and given at least 20 seconds 
to extend the time limit with a simple action (for example, "hit any 
key"), and the author is allowed to extend the time limit at least ten 
times.



Cheers,
Jan
