/**
    @class wxAcceleratorTable

    An accelerator table allows the application to specify a table of keyboard
    shortcuts for menu or button commands.

    The object ::wxNullAcceleratorTable is defined to be a table with no data, and
    is the initial accelerator table for a window.

    Example:

    @code
    wxAcceleratorEntry entries[4];
    entries[0].Set(wxACCEL_CTRL, (int) 'N', ID_NEW_WINDOW);
    entries[1].Set(wxACCEL_CTRL, (int) 'X', wxID_EXIT);
    entries[2].Set(wxACCEL_SHIFT, (int) 'A', ID_ABOUT);
    entries[3].Set(wxACCEL_NORMAL, WXK_DELETE, wxID_CUT);

    wxAcceleratorTable accel(4, entries);
    frame->SetAcceleratorTable(accel);
    @endcode

    @remarks
    An accelerator takes precedence over normal processing and can be a convenient
    way to program some event handling. For example, you can use an accelerator table
    to enable a dialog with a multi-line text control to accept CTRL-Enter as meaning
    'OK'.
