If more than one modifier key is held down when the mouse is pressed, the nShift argument contains the sum of the values for the modifier keys. For example, if the user holds CTRL while pressing the mouse button, the nShift argument contains 2. But If the user holds CTRL+ALT while pressing the mouse button, the nShift argument contains 6.
nXCoord, nYCoord

You can use this and the MouseEnter event to create rollover and mouseover behaviors as in DHTML.

A control receives a MouseLeave event when the user moves the mouse out of the control from a mouse position that was previously inside the control. In the case of overlapping or intersecting controls, the topmost control in the z-order receives the event.

A MouseLeave event is passed to objects on forms or toolbars. Forms and toolbars themselves do not receive this event.
