Checkboxes in Mac OS X.

In computing, a check box is a graphical user interface element (widget) that indicates a two-way choice or state (true/false) which can be edited by the user. Normally, check boxes are shown on the screen as a square box that can contain white space (for false) or a tick mark or X (for true).
