Mike,

You can use Windows API function GetKeyState to determine status of Shift key.

DECLARE SHORT GetKeyState IN WIN32API INTEGER
#define VK_SHIFT    0x10
#define VK_CONTROL  0x11
IF GetKeyState( VK_SHIFT ) < 0
  * SHIFT key is down
ENDIF

>I'm trying to determine if the Shift key is pressed when the MouseWheel event is fired for a grid. I've put the following code into the event:
>
>

>IF nShift = 1
>   WAIT WINDOW NOWAIT TRANSFORM(nShift)
>ENDIF
>

>
>It never executes. If I remove the IF/ENDIF, the wait window displays "0" if no key is pressed (as expected), but, no wait window appears if I press the Shift key. It appears to me that the grid's MouseWheel event does not respect the nShift parameter.
