Sergey,

Thanks for your suggestion. As usual it was a big help. I've learned alot about the GetKeyState function. However I can't get the state of the Shift Key. As a test, I placed the sample code from the message #12649 in my FieldMerge() method. I then called the FieldMerge() method from the DblClick method of my TextBoxes in a couple of columns in a Grid. Both the CTRL and ALT lines work fine. When I hold down the CTRL key and doubleclick the textbox the message appears as it should. But when I try to do that with the SHIFT key nothing happens.

Is SHIFT reserved in some way in VFP? I really want to use the CTRL and SHIFT keys for this function.

Thanks again.

PROCEDURE DblClick
  ThisForm.FieldMerge()
ENDPROC


PROCEDURE FieldMerge()
 DECLARE SHORT GetKeyState in WIN32API INTEGER KEYCODE
 *!* Is shift key pressed?
 IF (GETKEYSTATE(16) < 0)
     MESSAGEBOX("Shift key pressed")
 ENDIF
 *!* Is ctrl key pressed?
 IF (GETKEYSTATE(17) < 0)
     MESSAGEBOX("CTRL key pressed")
 ENDIF
 *!* Is alt key pressed?
 IF (GETKEYSTATE(18) < 0)
     MESSAGEBOX("Alt key pressed")
 ENDIF
ENDPROC
