The instance variable :caption can be assigned a character string to be displayed at position :capRow and :capCol whithin the :display() method. If the :caption string contains an ampersand (&), the ampersand is removed from the :caption string and the next character to the right of the ampersand is used as accelerator key while READ is active. The accelerator is displayed in a separate color (see :colorSpec).
