        <pre>Hide arrow is set to NEXT symbol type in PriorityMergedHBox.cxx.
I searched for the other symbols in class symboltype
enum class SymbolType : sal_uInt16
{
    DONTKNOW         = 0,
    IMAGE            = 1,
    ARROW_UP         = 2,
    ARROW_DOWN       = 3,
    ARROW_LEFT       = 4,
    ARROW_RIGHT      = 5,
    SPIN_UP          = 6,
    SPIN_DOWN        = 7,
    SPIN_LEFT        = 8,
    SPIN_RIGHT       = 9,
    FIRST            = 10,
    LAST             = 11,
    PREV             = 12,
    NEXT             = 13,
    PAGEUP           = 14,
    PAGEDOWN         = 15,
    PLAY             = 16,
    STOP             = 19,
    CLOSE            = 25,
    ROLLUP           = 26,
    ROLLDOWN         = 27,
    CHECKMARK        = 28,
    RADIOCHECKMARK   = 29,
    FLOAT            = 31,
    DOCK             = 32,
    HIDE             = 33,
    HELP             = 34,
    PLUS             = 35,
    MENU             = SymbolType::SPIN_DOWN
};

No symbol was matching(looks alike) to double arrow. So, I guess it cannot be
changed directly.</pre>
