The "Sign Up" feature of the Meetings page in the Sakai environment provides a control to expand all recurring meetings. This control is presented visually as a plus sign, placed directly to the left of the meeting displayed. However, this is a simulated control that cannot receive keyboard focus and relies solely on the use of a mouse to activate. As such, keyboard-only users are unable to either navigate to or activate 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 <span> element, developers must include a <tabindex> value of "0" on the <span>, as well as device-independent event handlers to provide support for activating the control with the keyboard.http://qa03-sakai.marist.edu:8080/portal/site/e72d72d4-f582-4dce-8261-6b923060787c/tool/82119d3e-4a6e-4b26-8cee-5b95a366fef6/signupMeetings#A61f53ad1718bfc170e3fab0ba86ca25-HTML
