Many of menu accelerators do not work. Firstly accelerator names like Ctrl+F disappeared from menu item texts. After additon:

pCommandBars->GetCommandbarsOptions()->bAutoUpdateShor tcuts = FALSE;

the accelerator names returned back to the item text. However these accelerators do not work at all! I read your advice to assign all accelerators to CMainFrame. This solution is not applicable for us because our MDI application opens different kinds of child windows. Each kind of child window has its own menu that contains its own accelerators. It means that, for example, Ctrl+F in one window calls metod A while the same accelerator in another window calls method B. So I can not assign both accelerators to CMainFrame. Is there a way to use same accelerators in different child windows?
