    store - Store source statement (called from PyShell.resetoutput).
    fetch - Fetch stored statement matching prefix already entered.
    history_next - Bound to <<history-next>> event (default Alt-N).
    history_prev - Bound to <<history-prev>> event (default Alt-P).

        .text - Idle wrapper of tk Text widget, with .bell().
        .history - source statements, possibly with multiple lines.
        .prefix - source already entered at prompt; filters history list.
        .pointer - index into history.
        .cyclic - wrap around history list (or not).
