documentation
"
    An EnterBox2 is like an EnterBox but with 2 action buttons.
    This is used (for example) in the search-boxes, where two ok-buttons
    'find-previous' and 'find-next' are needed in addition to the abort button.
    The protocol is like that of EnterBox, the additional buttons label
    can be set with 'okText2:aString' and its action with 'action2:aBlock'.
