I appologise.

I think that is not possible. Check what the Win32 API says:

========================================================
Windows provides a special keyboard interface for dialog boxes that
carries out special processing for several keys. The interface
generates messages that correspond to certain buttons in the dialog box
or changes the input focus from one control to another. Following are
the keys used in this interface and their respective actions. 

Key	Action
ALT+mnemonic	Moves the input focus to the first control (having the
WS_TABSTOP style) after the static control containing the given
mnemonic.
DOWN	Moves the input focus to the next control in the group.
ENTER	Sends a WM_COMMAND message to the dialog box procedure. The
wParam parameter is set to IDOK or control identifier of the default
push button.
ESC	Sends a WM_COMMAND message to the dialog box procedure. The wParam
parameter is set to IDCANCEL.
LEFT	Moves the input focus to the previous control in the group.
mnemonic	Moves the input focus to the first control (having the
WS_TABSTOP style) after the static control containing the given
mnemonic.
RIGHT	Moves the input focus to the next control in the group.
SHIFT+TAB	Moves the input focus to the previous control that has the
WS_TABSTOP style.
TAB	Moves the input focus to the next control that has the WS_TABSTOP
style.
UP	Moves the input focus to the previous control in the group.
 

The Win32 API automatically provides the keyboard interface for all
modal dialog boxes. It does not provide the interface for modeless
dialog boxes unless the application calls the IsDialogMessage function
to filter messages in its main message loop. This means that the
application must pass the message to IsDialogMessage immediately after
retrieving the message from the message queue. The function processes
the messages if it is for the dialog box and returns a nonzero value to
indicate that the message has been processed and must not be passed to
the TranslateMessage or DispatchMessage function. 

Because the dialog box keyboard interface uses direction keys to move
between controls in a dialog box, an application cannot use these keys
to scroll the contents of any modal dialog box or any modeless dialog
box for which IsDialogMessage is called. When a dialog box has scroll
bars, the application must provide an alternate keyboard interface for
the scroll bars. Note that the mouse interface for scrolling is
available when the system includes a mouse.

Don´t remember exactly but here is a start

http://msdn.microsoft.com/ and check for Platform SDK

Latest version of win32.hlp is given out by Borland. The file name is
b5ms.zip (17 Mb).

I´ll update soon my pages to the server. There should be the links
http://www.geocities.com/josempadron/

I don´t use, know, ... MFC.

Hope this helps. Don´t hesitate to ask more.

Cheers,
