The Meeting Details view of the environment provides a feature to allow the user to add additional participants to the currently selected meeting. However, the control to add participants is created by placing an onclick event handler on an HTML <label> element that does not receive keyboard focus. As such, keyboard-only users have no way of navigating to or activating the control.
Developers must ensure that all simulated controls implemented in the environment are keyboard accessible. As this control is created by placing an onclick event handler on a <label> element, a <tabindex> attribute with a value of "0" must be placed on the <label> to ensure that it can receive keyboard focus. Further, device-independent event handlers must be provided to allow the control to be activated by the keyboard as well as a mouse click.http://qa03-sakai.marist.edu:8080/portal/site/e72d72d4-f582-4dce-8261-6b923060787c/tool/82119d3e-4a6e-4b26-8cee-5b95a366fef6/organizer/orgSignupMeeting#A84dfddfb4fa546594fb0a95ead23702-HTML
