• A check box is a control that operates as a toggle, used to select one or more options from a fixed list. Each option must be composed of a text or graphic label and a graphic that shows whether or not the option is selected. (Motif fills in the box, Windows puts in a check mark).

  

• The options in the list must not be mutually exclusive -- check boxes are for choices that can be used in combination.

• An empty check box means the window is not selected; a filled check box means the item is selected.

• Selecting a check box does not affect its label.

• Selecting one option in a group must not affect the selection or deselection of any other option within that group.

• To separate check boxes from other information on the screen, surround the group of check boxes with blank space, or put them inside a group box..

• Used for selection, not for navigation or for invoking a command.

• Use positive terminology when designing check boxes. For a check box controlling a copy option, for example, the label should say Copy not Do not copy.
