helpFrame.prevPage()

    h.nexPage()
    h.prevPage()
    h.showPage(num)
    h.maxmin()

The "nextPage()", "prevPage()" and "showPage()" methods are the equivalents to the three navigation buttons in the titlebar of the helpFrame. That way a helpFrame can be steered programmatically, e.g. by menu buttons. The "maxmin()" method is equivalent to clicking the titlebar without moving: it will minimize or maximize the helpFrame.
