Keyboard accelerator doesn't catch CTRL + A

I have a window with a menu and an edit class handle. In the menu I have an Edit section with some options like cut, copy, paste, ecc.

I have defined 2 keyboard accelerators:

IDR_ACCELERATOR2 ACCELERATORS
BEGIN
    "A",            ID_EDIT_SALL,           VIRTKEY, CONTROL, NOINVERT
    "Z",            ID_EDIT_UNDO,           VIRTKEY, CONTROL, NOINVERT
END

CTRL + Z works, but CTRL + A doesn't. In the WM_COMMAND case I have this:

switch (LOWORD(wParam))
            {
            case ID_EDIT_CLEAR:
                SendMessage(hwndEdit, WM_CLEAR, 0, 0);
                break;
            case ID_EDIT_COPY:
                SendMessage(hwndEdit, WM_COPY, 0, 0);
                break;
            case ID_EDIT_CUT:
                SendMessage(hwndEdit, WM_CUT, 0, 0);
                break;
            case ID_EDIT_PASTE:
                SendMessage(hwndEdit, WM_PASTE, 0, 0);
                break;
            case ID_EDIT_SALL:
                SendMessage(hwndEdit, EM_SETSEL, 0, -1);
                break;
            case ID_EDIT_UNDO:
                SendMessage(hwndEdit, WM_UNDO, 0, 0);
                break;
            }

When I click on the menu option Select All, the option works well, it does select all the text in the editor handle, but when I try to use the keyboard combination CTRL+A Windows makes that error sound (like when you try to delete words in an empty document)
