Summary of Issue: working version of Changing timeout with a dropdown list
Comment (Including rationale for any proposed change):
The working version of Changing timeout with a dropdown list(http://www.w3.org/TR/WCAG-TECHS/working-examples/FLASH24/checkbox_for_extending_timelimit_as3.html) uses a checkbox although the example shows the sample codes for a dropdown list.

Proposed Change:
Rewrite the Example section or replace the working version by the dropdown list working example.
