That deppends on the key, but to make it simple use this
PUSHBUTTON "C&ancel",-1,0,0,100,15
and when you press the key a the button will be pushed.

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. ================================================================================== >I also noticed that you and a few other win32 programmers have been >talking about MSDN.

If you give the button an ID of IDCANCEL it will be handled by Windows. basically Windows defined IDOK and IDCANCEL and when enter and escape = are pressed knows exactly what to do. See http://msdn.microsoft.com/library/psdk/tools/dlgedit_4pdf.htm for = more info.

Jose, I realised that I could use the & to "accelerate" a key (I use this with my menu items, &Open, for example). >That depends on the key... Do you know the way I can make my "&Cancel" button respond to the "Esc" key? Are there special ways for each key (like DEFPUSHBUTTON, for "Enter")? I also noticed that you and a few other win32 programmers have been talking about MSDN. I have got a version of the SDK help (win32.hlp) but this is very old (based on the content) - it doesn't cover HTML help, only Win Help and a few other things are old too. I'll have a look at the MSDN site, but could you tell me the URL to download the SDK help or, the hyperlinks to take. Also, do you know whether I am using MFC or pure API? I don't use functions like OnInitDlg(), for dialogs I use a BOOL CALLBACK function. Oh, and what does SDK stand for, because although this came from Microsoft, it seems to cover some of the things I use (which I thought was pure API). I could be using both.
