Guideline 9. Design for device-independence.

Checkpoint 9.3 - For scripts, specify logical event handlers rather than device-dependent event handlers

How do I do it?

For scripts, applets and objects don't specify device-dependent event handlers. For example, choose onFocus rather than onMouseOver or onKeyPress.

How do I check that it meets the WCAG criteria?

Where <object>s and <applet>s exist (as verified by Guideline 8.1) they should not use device dependant scripts. These elements can be tested by attempting to control them independently with mouse only and keyboard only actions. Elements which cannot be controlled by both independently will cause the page the fail the check.
