CalendarKeyDown is a procedure which implements the OnKeyDown event handler for the Calendar control. The method ensures that the key down virtual key code represented by Key and Shift is applied to the Calendar control, and includes:

VK_RETURN, VK_SPACE: Calls ReturnDate to apply the selected date value in Month view, and signals the OnReturnDate event handler.
VK_ESCAPE: Calls Close to close the form.

If the virtual key code is handled in the method, the value in Key is set to zero (0). Otherwise, it is retained for use in event handlers at the Form or Application level.
