Hi,

AcceleratorTable does use a menu for some reason. However, you don't 
need to display the menu. Here's some sample code:

<code>

import wx

class MyFrame(wx.Frame):
    def __init__(self):
        wx.Frame.__init__(self, None, wx.ID_ANY, title='Accelerator Test')

        self.panel = wx.Panel(self, wx.ID_ANY)

        # menubar code
        menubar = wx.MenuBar()
        fileMenu = wx.Menu()
        save_menu_item = fileMenu.Append(-1, '&Save\tCtrl+S', 'Saves the 
Data')
        printDefault_menu_item = fileMenu.Append(-1, '&Print\tCtrl+P', 
'Prints to Default Printer')
        menubar.Append(fileMenu, '&File')
        self.SetMenuBar(menubar)

        # bind events to menu items
        self.Bind(wx.EVT_MENU, self.onSave, save_menu_item)
        self.Bind(wx.EVT_MENU, self.onPrint, printDefault_menu_item)

        # accelerator table code
        accel_tbl = wx.AcceleratorTable([(wx.ACCEL_CTRL, ord('P'), 
printDefault_menu_item.GetId()),
                                         (wx.ACCEL_CTRL, ord('S'), 
save_menu_item.GetId())
                                         ])
        self.SetAcceleratorTable(accel_tbl)

        # show the frame
        self.Show()

    def onPrint(self, event):
        print 'in onPrint'

    def onSave(self, event):
        print 'in onSave'

if __name__ == '__main__':
    app = wx.PySimpleApp()
    frm = MyFrame()
    app.MainLoop()

</code>

If you comment out the line "menubar.Append(fileMenu, '&File')", then my 
menu will not show up, but the keyboard events that I've bound in my 
AcceleratorTable are still able to be fired.

A little goofy, but it works!
